@joshkolenko/inline-html v0.4.1
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-htmlSay 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.tsFor 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',
});
// ...
})();
