What is vite-plugin-css-injected-by-js?

What are vite-plugin-css-injected-by-js's main functionalities?

Inject CSS into JavaScript

This feature allows you to configure Vite to inject CSS directly into the JavaScript bundle. By using the `cssInjectedByJsPlugin` in the Vite configuration, the CSS will be included in the JavaScript output, ensuring that styles are applied as soon as the JavaScript is executed.

import { defineConfig } from 'vite';
import cssInjectedByJsPlugin from 'vite-plugin-css-injected-by-js';

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

README

Vite Plugin: CssInjectedByJs

A Vite plugin that takes the CSS and adds it to the page through the JS. For those who want a single JS file.

How does it work

Essentially what it does is take all the CSS generated by the build process and add it via JavaScript. The CSS file is therefore not generated and the declaration in the generated HTML file is also removed. You can also configure when the CSS injection will be executed (before or after your app code).

Installation

npm i vite-plugin-css-injected-by-js --save

Usage

import cssInjectedByJsPlugin from 'vite-plugin-css-injected-by-js'

export default {
  plugins: [
    cssInjectedByJsPlugin(),
  ]
}

Configurations

When you add the plugin, you can provide a configuration object. For now, you can configure only when the injection of CSS is done at execution time topExecutionPriority.

topExecutionPriority

The default behavior adds the injection of CSS before your bundle code. If you provide topExecutionPriority equal to: false the code of injection will be added after the bundle code. This is an example:

import cssInjectedByJsPlugin from 'vite-plugin-css-injected-by-js'

export default {
  plugins: [
    cssInjectedByJsPlugin({topExecutionPriority: false}),
  ]
}

Contributing

When you make changes to plugin locally, you may want to build the js from the typescript file of the plugin. Here the guidelines:

Install

npm install

Build plugin
