## Installation
|
|
|
|
npm install inline-html
|
|
|
|
## Usage
|
|
|
|
This:
|
|
|
|
```js
|
|
var inlineHtml = require('inline-html');
|
|
inlineHtml('path/to/file.html').then(function (html) {
|
|
...
|
|
});
|
|
```
|
|
|
|
Turns this:
|
|
|
|
```html
|
|
<link rel="stylesheet/less" href="main.less"/>
|
|
<style>
|
|
div { background-image: url('path/to/file'); }
|
|
</style>
|
|
<div style="background-image: url('path/to/file');"></div>
|
|
<img src="path/to/file"/>
|
|
```
|
|
|
|
Into this:
|
|
|
|
```html
|
|
<style>
|
|
@font-face { src: url('data:...'); }
|
|
div { background-image: url('data:...'); }
|
|
</style>
|
|
<style>
|
|
div { background-image: url('data:...'); }
|
|
</style>
|
|
<div style="background-image: url('data:...');"></div>
|
|
<img src="data:..."/>
|
|
```
|
|
|
|
Where:
|
|
|
|
- `main.less`
|
|
|
|
```css
|
|
@import (inline) 'main.css';
|
|
div { background-image: url('path/to/file'); }
|
|
```
|
|
|
|
- `main.css`
|
|
|
|
```css
|
|
@font-face { src: url('path/to/file'); }
|
|
```
|
|
|
|
## API
|
|
|
|
### inlineHtml( filename [, options] )
|
|
|
|
Reads an HTML file and embeds the contents of local assets referenced by the following elements and data types:
|
|
|
|
- LESS stylesheets - The LESS is compiled and the result is inlined within a `<style>` element.
|
|
|
|
<link rel="stylesheet/less" href="main.less"/> -> <style>...</style>
|
|
|
|
- CSS url data types - The reference path is replaced with a datauri. These can be used in linked stylesheets, style elements, and element style attributes.
|
|
|
|
url('file.ext') -> url('data:...')
|
|
|
|
- Images - The source path is replaced with a datauri.
|
|
|
|
<img src="file.ext"/> -> <img src="data:..."/>
|
|
|
|
Returns a `Promise` that is fulfilled with an `html` string or a `results` object depending on the value of `options.verbose`.
|
|
|
|
#### Arguments
|
|
|
|
- `filename` - The filename of the HTML file to be inlined. Relative file paths are resolved relative to the filename directory.
|
|
- `options`
|
|
- `less` - An object containing LESS options to pass to the less compiler. Defaults to `{}`.
|
|
- `verbose` - A boolean that determines the promises fulfillment value. Defaults to `false`.
|
|
- `true`: promise is resolved with an instance of `Results`
|
|
- `false`: promise is resolved with `html`
|
|
|
|
#### Results object
|
|
|
|
The `Promise` returned by this function is optionally fulfilled with a `results` object that has the following properties:
|
|
|
|
- `html` - The inlined html
|
|
- `files` - An array of filenames of the inlined local assets.
