Vite-plugin-inline-source NPM

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

import { defineConfig } from "vite";
import inlineSource from "vite-plugin-inline-source";

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

style.css

body {
  background-color: red;
}

index.html

<html>
  <style inline-source src="style.css"></style>
</html>

Resulting index.html after build

<html>
  <style inline-source>body {
  background-color: red;
}
  </style>
</html>

Options

replaceTags

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']
