+# ES6-Promise (subset of [rsvp.js](https://github.com/tildeio/rsvp.js))
+
+This is a polyfill of the [ES6 Promise](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-constructor). The implementation is a subset of [rsvp.js](https://github.com/tildeio/rsvp.js), if you're wanting extra features and more debugging options, check out the [full library](https://github.com/tildeio/rsvp.js).
+
+For API details and how to use promises, see the <a href="http://www.html5rocks.com/en/tutorials/es6/promises/">JavaScript Promises HTML5Rocks article</a>.
+
+## Downloads
+
+* [es6-promise](https://raw.githubusercontent.com/jakearchibald/es6-promise/master/dist/es6-promise.js)
+* [es6-promise-min](https://raw.githubusercontent.com/jakearchibald/es6-promise/master/dist/es6-promise.min.js)
+
+## Node.js
+
+To install:
+
+```sh
+npm install es6-promise
+```
+
+To use:
+
+```js
+var Promise = require('es6-promise').Promise;
+```
+
+## Usage in IE<9
+
+`catch` is a reserved word in IE<9, meaning `promise.catch(func)` throws a syntax error. To work around this, you can use a string to access the property as shown in the following example.
+
+However, please remember that such technique is already provided by most common minifiers, making the resulting code safe for old browsers and production:
+
+```js
+promise['catch'](function(err) {
+  // ...
+});
+```
+
+Or use `.then` instead:
+
+```js
+promise.then(undefined, function(err) {
+  // ...
+});
+```
+
+## Auto-polyfill
+
+To polyfill the global environment (either in Node or in the browser via CommonJS) use the following code snippet:
+
+```js
+require('es6-promise').polyfill();
+```
+
+Notice that we don't assign the result of `polyfill()` to any variable. The `polyfill()` method will patch the global environment (in this case to the `Promise` name) when called.
+
+## Building & Testing
+
+* `npm run build` to build
+* `npm test` to run tests
+* `npm start` to run a build watcher, and webserver to test 
+* `npm run test:server` for a testem test runner and watching builder

+      Promise objects represent the eventual result of an asynchronous operation. The
+      primary way of interacting with a promise is through its `then` method, which
+      registers callbacks to receive either a promise's eventual value or the reason
+      why the promise cannot be fulfilled.
+
+      Terminology
+      -----------
+
+      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+      - `thenable` is an object or function that defines a `then` method.
+      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+      - `exception` is a value that is thrown using the throw statement.
+      - `reason` is a value that indicates why a promise was rejected.
+      - `settled` the final resting state of a promise, fulfilled or rejected.
+
+      A promise can be in one of three states: pending, fulfilled, or rejected.
+
+      Promises that are fulfilled have a fulfillment value and are in the fulfilled
+      state.  Promises that are rejected have a rejection reason and are in the
+      rejected state.  A fulfillment value is never a thenable.
+
+      Promises can also be said to *resolve* a value.  If this value is also a
+      promise, then the original promise's settled state will match the value's
+      settled state.  So a promise that *resolves* a promise that rejects will
+      itself reject, and a promise that *resolves* a promise that fulfills will
+      itself fulfill.
+
+
+      Basic Usage:
+      ------------
+
+      ```js
+      var promise = new Promise(function(resolve, reject) {
+        // on success
+        resolve(value);
+
+        // on failure
+        reject(reason);
+      });
+
+      promise.then(function(value) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Advanced Usage:
+      ---------------
+
+      Promises shine when abstracting away asynchronous interactions such as
+      `XMLHttpRequest`s.
+
+      ```js
+      function getJSON(url) {
+        return new Promise(function(resolve, reject){
+          var xhr = new XMLHttpRequest();
+
+          xhr.open('GET', url);
+          xhr.onreadystatechange = handler;
+          xhr.responseType = 'json';
+          xhr.setRequestHeader('Accept', 'application/json');
+          xhr.send();
+
+          function handler() {
+            if (this.readyState === this.DONE) {
+              if (this.status === 200) {
+                resolve(this.response);
+              } else {
+                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+              }
+            }
+          };
+        });
+      }
+
+      getJSON('/posts.json').then(function(json) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Unlike callbacks, promises are great composable primitives.
+
+      ```js
+      Promise.all([
+        getJSON('/posts'),
+        getJSON('/comments')
+      ]).then(function(values){
+        values[0] // => postsJSON
+        values[1] // => commentsJSON
+
+        return values;
+      });
+      ```

+      this._subscribers = [];
+

+    lib$es6$promise$promise$$Promise.prototype = {
+      constructor: lib$es6$promise$promise$$Promise,
+
+    /**
+      The primary way of interacting with a promise is through its `then` method,
+      which registers callbacks to receive either a promise's eventual value or the
+      reason why the promise cannot be fulfilled.
+
+      ```js
+      findUser().then(function(user){
+        // user is available
+      }, function(reason){
+        // user is unavailable, and you are given the reason why
+      });
+      ```
+
+      Chaining
+      --------
+
+      The return value of `then` is itself a promise.  This second, 'downstream'
+      promise is resolved with the return value of the first promise's fulfillment
+      or rejection handler, or rejected if the handler throws an exception.
+
+      ```js
+      findUser().then(function (user) {
+        return user.name;
+      }, function (reason) {
+        return 'default name';
+      }).then(function (userName) {
+        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+        // will be `'default name'`
+      });
+
+      findUser().then(function (user) {
+        throw new Error('Found user, but still unhappy');
+      }, function (reason) {
+        throw new Error('`findUser` rejected and we're unhappy');
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+      });
+      ```
+      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+      ```js
+      findUser().then(function (user) {
+        throw new PedagogicalException('Upstream error');
+      }).then(function (value) {
+        // never reached
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // The `PedgagocialException` is propagated all the way down to here
+      });
+      ```
+
+      Assimilation
+      ------------
+
+      Sometimes the value you want to propagate to a downstream promise can only be
+      retrieved asynchronously. This can be achieved by returning a promise in the
+      fulfillment or rejection handler. The downstream promise will then be pending
+      until the returned promise is settled. This is called *assimilation*.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // The user's comments are now available
+      });
+      ```
+
+      If the assimliated promise rejects, then the downstream promise will also reject.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // If `findCommentsByAuthor` fulfills, we'll have the value here
+      }, function (reason) {
+        // If `findCommentsByAuthor` rejects, we'll have the reason here
+      });
+      ```
+

+
+      Synchronous Example
+
+      ```javascript
+      var result;
+
+      try {

+/**
+  Promise objects represent the eventual result of an asynchronous operation. The
+  primary way of interacting with a promise is through its `then` method, which
+  registers callbacks to receive either a promise's eventual value or the reason
+  why the promise cannot be fulfilled.
+
+  Terminology
+  -----------
+
+  - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+  - `thenable` is an object or function that defines a `then` method.
+  - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+  - `exception` is a value that is thrown using the throw statement.
+  - `reason` is a value that indicates why a promise was rejected.
+  - `settled` the final resting state of a promise, fulfilled or rejected.
+
+  A promise can be in one of three states: pending, fulfilled, or rejected.
+
+  Promises that are fulfilled have a fulfillment value and are in the fulfilled
+  state.  Promises that are rejected have a rejection reason and are in the
+  rejected state.  A fulfillment value is never a thenable.
+
+  Promises can also be said to *resolve* a value.  If this value is also a
+  promise, then the original promise's settled state will match the value's
+  settled state.  So a promise that *resolves* a promise that rejects will
+  itself reject, and a promise that *resolves* a promise that fulfills will
+  itself fulfill.
+
+
+  Basic Usage:
+  ------------
+
+  ```js
+  var promise = new Promise(function(resolve, reject) {
+    // on success
+    resolve(value);
+
+    // on failure
+    reject(reason);
+  });
+
+  promise.then(function(value) {
+    // on fulfillment
+  }, function(reason) {
+    // on rejection
+  });
+  ```
+
+  Advanced Usage:
+  ---------------
+
+  Promises shine when abstracting away asynchronous interactions such as
+  `XMLHttpRequest`s.
+
+  ```js
+  function getJSON(url) {
+    return new Promise(function(resolve, reject){
+      var xhr = new XMLHttpRequest();
+
+      xhr.open('GET', url);
+      xhr.onreadystatechange = handler;
+      xhr.responseType = 'json';
+      xhr.setRequestHeader('Accept', 'application/json');
+      xhr.send();
+
+      function handler() {
+        if (this.readyState === this.DONE) {
+          if (this.status === 200) {
+            resolve(this.response);
+          } else {
+            reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+          }
+        }
+      };
+    });
+  }
+
+  getJSON('/posts.json').then(function(json) {
+    // on fulfillment
+  }, function(reason) {
+    // on rejection
+  });
+  ```
+
+  Unlike callbacks, promises are great composable primitives.
+
+  ```js
+  Promise.all([
+    getJSON('/posts'),
+    getJSON('/comments')
+  ]).then(function(values){
+    values[0] // => postsJSON
+    values[1] // => commentsJSON
+
+    return values;
+  });
+  ```
+

+  @param {function} resolver

+  this._subscribers = [];

+  if (noop !== resolver) {
+    if (!isFunction(resolver)) {
+      needsResolver();
+    }
+
+    if (!(this instanceof Promise)) {
+      needsNew();
+    }
+
+    initializePromise(this, resolver);
+  }

+/**
+  The primary way of interacting with a promise is through its `then` method,
+  which registers callbacks to receive either a promise's eventual value or the
+  reason why the promise cannot be fulfilled.
+
+  ```js
+  findUser().then(function(user){
+    // user is available
+  }, function(reason){
+    // user is unavailable, and you are given the reason why
+  });
+  ```
+
+  Chaining
+  --------
+
+  The return value of `then` is itself a promise.  This second, 'downstream'
+  promise is resolved with the return value of the first promise's fulfillment
+  or rejection handler, or rejected if the handler throws an exception.
+
+  ```js
+  findUser().then(function (user) {
+    return user.name;
+  }, function (reason) {
+    return 'default name';
+  }).then(function (userName) {
+    // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+    // will be `'default name'`
+  });
+
+  findUser().then(function (user) {
+    throw new Error('Found user, but still unhappy');
+  }, function (reason) {
+    throw new Error('`findUser` rejected and we're unhappy');
+  }).then(function (value) {
+    // never reached
+  }, function (reason) {
+    // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+    // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+  });
+  ```
+  If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+  ```js
+  findUser().then(function (user) {
+    throw new PedagogicalException('Upstream error');
+  }).then(function (value) {
+    // never reached
+  }).then(function (value) {
+    // never reached
+  }, function (reason) {
+    // The `PedgagocialException` is propagated all the way down to here
+  });
+  ```
+
+  Assimilation
+  ------------
+
+  Sometimes the value you want to propagate to a downstream promise can only be
+  retrieved asynchronously. This can be achieved by returning a promise in the
+  fulfillment or rejection handler. The downstream promise will then be pending
+  until the returned promise is settled. This is called *assimilation*.
+
+  ```js
+  findUser().then(function (user) {
+    return findCommentsByAuthor(user);
+  }).then(function (comments) {
+    // The user's comments are now available
+  });
+  ```
+
+  If the assimliated promise rejects, then the downstream promise will also reject.
+
+  ```js
+  findUser().then(function (user) {
+    return findCommentsByAuthor(user);
+  }).then(function (comments) {
+    // If `findCommentsByAuthor` fulfills, we'll have the value here
+  }, function (reason) {
+    // If `findCommentsByAuthor` rejects, we'll have the reason here
+  });
+  ```
+
+  Simple Example
+  --------------
+
+  Synchronous Example
+
+  ```javascript
+  var result;
+
+  try {
+    result = findResult();
+    // success
+  } catch(reason) {
+    // failure
+  }
+  ```

+  findResult(function(result, err){
+    if (err) {
+      // failure
+    } else {

+
+  If any of the `promises` given to `all` are rejected, the first promise
+  that is rejected will be given as an argument to the returned promises's

+Kerberos
+========
+
+The `kerberos` package is a C++ extension that requires a build environment to be installed on your system. You must be able to build node.js itself to be able to compile and install the `kerberos` module. Furthermore the `kerberos` module requires the MIT Kerberos package to correctly compile on UNIX operating systems. Consult your UNIX operation system package manager what libraries to install.
+
+{{% note class="important" %}}
+Windows already contains the SSPI API used for Kerberos authentication. However you will need to install a full compiler tool chain using visual studio C++ to correctly install the kerberos extension.
+{{% /note %}}
+
+### Diagnosing on UNIX
+
+If you don’t have the build essentials it won’t build. In the case of linux you will need gcc and g++, node.js with all the headers and python. The easiest way to figure out what’s missing is by trying to build the kerberos project. You can do this by performing the following steps.
+
+```
+git clone https://github.com/christkv/kerberos.git
+cd kerberos
+npm install
+```
+
+If all the steps complete you have the right toolchain installed. If you get node-gyp not found you need to install it globally by doing.
+
+```
+npm install -g node-gyp
+```
+
+If correctly compiles and runs the tests you are golden. We can now try to install the kerberos module by performing the following command.
+
+```
+cd yourproject
+npm install kerberos --save
+```
+
+If it still fails the next step is to examine the npm log. Rerun the command but in this case in verbose mode.
+
+```
+npm --loglevel verbose install kerberos
+```
+
+This will print out all the steps npm is performing while trying to install the module.
+
+### Diagnosing on Windows
+
+A known compiler tool chain known to work for compiling `kerberos` on windows is the following.
+
+* Visual Studio c++ 2010 (do not use higher versions)
+* Windows 7 64bit SDK
+* Python 2.7 or higher
+
+Open visual studio command prompt. Ensure node.exe is in your path and install node-gyp.
+
+```
+npm install -g node-gyp
+```
+
+Next you will have to build the project manually to test it. Use any tool you use with git and grab the repo.
+
+```
+git clone https://github.com/christkv/kerberos.git
+cd kerberos
+npm install
+node-gyp rebuild
+```
+
+This should rebuild the driver successfully if you have everything set up correctly.
+
+### Other possible issues
+
+Your python installation might be hosed making gyp break. I always recommend that you test your deployment environment first by trying to build node itself on the server in question as this should unearth any issues with broken packages (and there are a lot of broken packages out there).
+
+Another thing is to ensure your user has write permission to wherever the node modules are being installed.

+
+Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
+
+This project also contains some helper utilities that make addon development a bit more pleasant.

+## News & Updates
+
+<a name="usage"></a>
+## Usage
+
+Simply add **NAN** as a dependency in the *package.json* of your Node addon:
+
+``` bash
+$ npm install --save nan
+```
+
+Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
+
+``` python
+"include_dirs" : [
+    "<!(node -e \"require('nan')\")"
+]
+```
+
+This works like a `-I<path-to-NAN>` when compiling your addon.
+
+<a name="example"></a>
+## Example
+
+Just getting started with Nan? Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.
+
+For a simpler example, see the **[async pi estimation example](https://github.com/nodejs/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does. Below are just some parts of the full example that illustrate the use of **NAN**.
+
+For another example, see **[nan-example-eol](https://github.com/CodeCharmLtd/nan-example-eol)**. It shows newline detection implemented as a native addon.

+Additional to the NAN documentation below, please consult:
+
+* [The V8 Getting Started Guide](https://developers.google.com/v8/get_started)

+* [V8 API Documentation](http://v8docs.nodesource.com/)
+
+<!-- START API -->
+
+### JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://developers.google.com/v8/embed#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+ - <a href="doc/methods.md#api_nan_set_instance_template"><b><code>Nan::SetInstanceTemplate()</code></b></a>
+
+### Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
+
+### Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.
+

+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
+
+### New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.
+
+ - <a href="doc/new.md#api_nan_new"><b><code>Nan::New()</code></b></a>
+ - <a href="doc/new.md#api_nan_undefined"><b><code>Nan::Undefined()</code></b></a>

+ - <a href="doc/new.md#api_nan_false"><b><code>Nan::False()</code></b></a>
+ - <a href="doc/new.md#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
+
+
+### Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
+
+ - <a href="doc/converters.md#api_nan_to"><b><code>Nan::To()</code></b></a>
+
+### Maybe Types
+
+The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

+ - <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
+
+
+### Errors
+
+NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
+
+Note that an Error object is simply a specialized form of `v8::Value`.
+
+Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.

+
+
+### Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.
+
+ - <a href="doc/buffers.md#api_nan_new_buffer"><b><code>Nan::NewBuffer()</code></b></a>
+ - <a href="doc/buffers.md#api_nan_copy_buffer"><b><code>Nan::CopyBuffer()</code></b></a>
+ - <a href="doc/buffers.md#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
+
+### Nan::Callback
+
+`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
+
+ - <a href="doc/callback.md#api_nan_callback"><b><code>Nan::Callback</code></b></a>
+
+### Asynchronous work helpers
+
+`Nan::AsyncWorker` and `Nan::AsyncProgressWorker` are helper classes that make working with asynchronous code easier.

+
+
+### V8 internals
+
+The hooks to access V8 internals—including GC and statistics—are different across the supported versions of V8, therefore NAN provides its own hooks that call the appropriate V8 methods.

+## Governance & Contributing
+
+NAN is governed by the [io.js](https://iojs.org/) Addon API Working Group
+
+### Addon API Working Group (WG)
+
+The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
+
+Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other io.js projects.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project [README.md](./README.md#collaborators).
+
+Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
+
+_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
+
+For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
+
+### Consensus Seeking Process
+
+The WG follows a [Consensus Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
+
+Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
+
+If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.
+
+### Developer's Certificate of Origin 1.0

+## Asynchronous work helpers
+
+`Nan::AsyncWorker` and `Nan::AsyncProgressWorker` are helper classes that make working with asynchronous code easier.

+### Nan::AsyncWorker
+
+`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
+
+Definition:
+
+```c++
+class AsyncWorker {
+ public:
+  explicit AsyncWorker(Callback *callback_);
+
+  virtual ~AsyncWorker();
+
+  virtual void WorkComplete();
+
+  void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);

+
+  const char* ErrorMessage();
+};

+
+<a name="api_nan_async_progress_worker"></a>
+### Nan::AsyncProgressWorker
+
+`Nan::AsyncProgressWorker` is an _abstract_ class that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+Definition:
+
+```c++
+class AsyncProgressWorker : public AsyncWorker {
+ public:
+  explicit AsyncProgressWorker(Callback *callback_);
+
+  virtual ~AsyncProgressWorker();
+
+  void WorkProgress();
+
+  class ExecutionProgress {

+
+  virtual void Destroy();
+```
+
+<a name="api_nan_async_queue_worker"></a>
+### Nan::AsyncQueueWorker
+
+`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.
+

+### Nan::NewBuffer()
+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.

+### Nan::CopyBuffer()
+
+Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
+
+Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.

+## Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.

+### Nan::MaybeLocal
+
+A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/io.js-3.0/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
+
+If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::MaybeLocal {
+ public:
+  MaybeLocal();
+
+  template<typename S> MaybeLocal(v8::Local<S> that);
+
+  bool IsEmpty() const;
+
+  template<typename S> bool ToLocal(v8::Local<S> *out);
+
+  // Will crash if the MaybeLocal<> is empty.
+  v8::Local<T> ToLocalChecked();
+
+  template<typename S> v8::Local<S> FromMaybe(v8::Local<S> default_value) const;
+};
+```
+
+See the documentation for [`v8::MaybeLocal`](https://v8docs.nodesource.com/io.js-3.0/d8/d7d/classv8_1_1_maybe_local.html) for further details.

+### Nan::Maybe
+
+A simple `Nan::Maybe` type, representing an object which may or may not have a value, see https://hackage.haskell.org/package/base/docs/Data-Maybe.html.
+
+If an API method returns a `Nan::Maybe<>`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, a "Nothing" value is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::Maybe {
+ public:
+  bool IsNothing() const;
+  bool IsJust() const;
+
+  // Will crash if the Maybe<> is nothing.
+  T FromJust();
+

+## JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://developers.google.com/v8/embed#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+
+`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/io.js-3.0/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
+
+Definition:
+
+```c++

+### Nan::ReturnValue
+
+`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/io.js-3.0/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
+
+Example usage:

+### Method declaration
+
+JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
+
+```c++
+typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
+```
+
+Example:
+
+```c++
+void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+
+You do not need to declare a new `HandleScope` within a method as one is implicitly created for you.
+
+**Example usage**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static void Bar(const Nan::FunctionCallbackInfo<v8::Value>& info);
+  static void Baz(const Nan::FunctionCallbackInfo<v8::Value>& info);
+}
+
+
+// .cc:
+void Foo::Bar(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+
+void Foo::Baz(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+A helper macro `NAN_METHOD(methodname)` exists, compatible with NAN v1 method declarations.
+
+**Example usage with `NAN_METHOD(methodname)`**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static NAN_METHOD(Bar);
+  static NAN_METHOD(Baz);
+}
+
+
+// .cc:
+NAN_METHOD(Foo::Bar) {
+  ...
+}
+
+NAN_METHOD(Foo::Baz) {
+  ...
+}
+```
+
+Use [`Nan::SetPrototypeMethod`](#api_nan_set_prototype_method) to attach a method to a JavaScript function prototype or [`Nan::SetMethod`](#api_nan_set_method) to attach a method directly on a JavaScript object.

+
+
+<a name="api_nan_new"></a>
+### Nan::New()
+
+`Nan::New()` should be used to instantiate new JavaScript objects.
+
+Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/io.js-3.0/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
+
+Signatures:
+
+Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
+
+Empty objects:
+
+```c++
+Nan::New<T>();
+```
+
+Generic single and multiple-argument:
+
+```c++
+Nan::New<T>(A0 arg0);
+Nan::New<T>(A0 arg0, A1 arg1);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
+```
+
+For creating `v8::FunctionTemplate` and `v8::Function` objects:
+
+_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
+
+```c++
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>());
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>(),
+            A2 a2 = A2());
+```
+
+Native types:
+
+```c++
+v8::Local<v8::Boolean> Nan::New<T>(bool value);
+v8::Local<v8::Int32> Nan::New<T>(int32_t value);
+v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
+v8::Local<v8::Number> Nan::New<T>(double value);
+v8::Local<v8::String> Nan::New<T>(std::string const& value);
+v8::Local<v8::String> Nan::New<T>(const char * value, int length);
+v8::Local<v8::String> Nan::New<T>(const char * value);
+v8::Local<v8::String> Nan::New<T>(const uint16_t * value);
+```
+
+Specialized types:
+
+```c++
+v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
+v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
+v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
+```
+
+Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/io.js-3.0/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

+## Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+<a name="api_nan_weak_callback_info"></a>
+### Nan::WeakCallbackInfo
+
+`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.
+
+Definition:
+
+```c++
+template<typename T> class WeakCallbackInfo {
+ public:
+  typedef void (*Callback)(const WeakCallbackInfo<T>& data);
+
+  v8::Isolate *GetIsolate() const;
+
+  /**
+   * Get the parameter that was associated with the weak handle.
+   */
+  T *GetParameter() const;
+
+  /**
+   * Get pointer from internal field, index can be 0 or 1.
+   */
+  void *GetInternalField(int index) const;
+};
+```
+
+Example usage:
+
+```c++
+void weakCallback(const WeakCallbackInfo<int> &data) {
+  int *parameter = data.GetParameter();
+  delete parameter;
+}
+
+Persistent<v8::Object> obj;
+int *data = new int(0);
+obj.SetWeak(data, callback, WeakCallbackType::kParameter);
+```
+
+See the V8 documentation for [`WeakCallbackInfo`](https://v8docs.nodesource.com/io.js-3.0/d8/d06/classv8_1_1_weak_callback_info.html) for further information.
+
+<a name="api_nan_weak_callback_type"></a>
+### Nan::WeakCallbackType
+
+Represents the type of a weak callback.
+A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
+A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
+Note that only `v8::Object`s and derivatives can have internal fields.
+
+Definition:

+## Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
+
+<a name="api_nan_handle_scope"></a>
+### Nan::HandleScope
+
+A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/io.js-3.0/d3/d95/classv8_1_1_handle_scope.html).
+
+Definition:
+
+```c++
+class Nan::HandleScope {
+ public:
+  Nan::HandleScope();
+  static int NumberOfHandles();
+};
+```
+
+Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
+
+Example:
+
+```c++
+// new object is created, it needs a new scope:
+void Pointless() {
+  Nan::HandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+
+// JavaScript-accessible method already has a HandleScope
+NAN_METHOD(Pointless2) {
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+```
+
+<a name="api_nan_escapable_handle_scope"></a>
+### Nan::EscapableHandleScope
+
+Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
+
+Definition:
+
+```c++
+class Nan::EscapableHandleScope {
+ public:
+  Nan::EscapableHandleScope();
+  static int NumberOfHandles();
+  template<typename T> v8::Local<T> Escape(v8::Local<T> value);
+}
+```
+
+Use `Escape(value)` to return the object.
+
+Example:
+
+```c++
+v8::Local<v8::Object> EmptyObj() {
+  Nan::EscapableHandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+  return scope.Escape(obj);
