vite-plugin-inline-source


A Vite plugin which inlines source files in HTML files where the inline-source attribute is present. This is similar in premise to vite-plugin-singlefile, but allows you to control which assets are inlined.

This plugin was heavily influenced by markup-inline-loader for webpack. I wanted the same functionality, but couldn't find a suitable replacement in the Vite ecosystem.

Example Usage

Check out the interactive demo on StackBlitz!

vite.config.ts
``typescript
import { defineConfig } from "vite";
import inlineSource from "vite-plugin-inline-source";

export default defineConfig({
plugins: [
inlineSource(),
],
});
`

style.css
`css
body {
background-color: red;
}
`

index.html
`html



`

Resulting index.html after build
`html



`

Options

$3

The custom attribute to use for triggering inlining of source files. By default, the plugin uses inline-source. You can set this to a different attribute name if needed.

- type: string
- default: inline-source

$3

Tags that should be replaced in the HTML file.

For example, style and script tags are not replaced by default because the corresponding css/js file would not contain the style or script tag. However, with svg tags, the corresponding svg file would contain the svg tag, so the svg tags in the HTML file are replaced. See the unit tests for more explicit examples.

- type: string[]
- default: ['svg', 'math']

- type: boolean
- default: true
