inline-html
As of V0.4.1
this module is now ESM
only. Use previous versions for CJS
support.
This module takes a path to an HTML file and returns a promise that resolves with a string of HTML. Output HTML has all link
and script
tags with the inline
attribute replaced with the content of the linked file compiled and inlined in a style
or script
tag. Output HTML is formatted using Prettier.
How it works
Install the package in your project
npm i @joshkolenko/inline-html
Say you have a project named example
that consists of 3 files: index.html
, example.scss
& example.js
and a file index.js
outside of the project where you're going to be calling the inlineHTML
module.
The folder structure looks like this:
├── index.js
└── src
├── index.html
├── index.ts
├── main.scss
└── module.ts
For this example, this is the code in index.html
. (See other example code in example/
)
<body>
<h2>Hello, world!</h2>
</body>
<link rel="stylesheet" href="main.scss" inline />
<script src="index.ts" inline></script>
Notice the inline
attribute on the link
and script
tags. This tells inlineHTML
that you want these tags replaced with the compiled contents of the referenced files.
In index.js
you can call inlineHTML
like this:
import { inlineHTML } from '@joshkolenko/inline-html';
(async () => {
const html = await inlineHTML('example/index.html');
// ...
})();
This is the resulting html
<body>
<h2>Hello, world!</h2>
</body>
<style>
body {
display: flex;
align-items: center;
justify-content: center;
}
body h2 {
font-size: 2rem;
}
</style>
<script>
'use strict';
(() => {
// example/src/module.ts
var str = 'Hello, world!';
// example/src/index.ts
console.log(str);
})();
</script>
You can also provide an options
object as the second argument.
Property | Description |
---|---|
attribute? | Attribute inlineHTML will look for to inline tags. Defaults to inline
|
dir? | Directory where paths in html string be will resolved from. Defaults to process.cwd()
|
format? | Prettier config object. Default values are printWidth: 200 , tabWidth: 2 , semi: true
|
loadPaths? | Paths on the filesystem that Sass will look in when resolving imports |
For more Prettier options, see the documentation.
For example:
import { inlineHTML } from '@joshkolenko/inline-html';
(async () => {
const html = await inlineHTML('example/index.html', {
attribute: 'bundle',
format: {
printWidth: 60,
tabWidth: 3,
semi: false,
},
});
// ...
})();
As of V0.3.0
, you can now pass an html string as the first parameter to inlineHTML
. The paths in the html
string will be resolved relative to the current working directory, or you can pass a dir
option to the Options
object to resolve the paths relative to the specified path.
(async () => {
const htmlPath = path.resolve('example/src/index.html');
const htmlStr = await fs.readFile(htmlPath, 'utf8');
const html = await inlineHTML(htmlStr, {
dir: 'example',
});
// ...
})();
