Vite Plugin Dev Manifest

Vite plugin for generating a dev version of manifest file for backend integration, so you can include script and styles without explicitly knowing what to include.

This way, you can run vite dev server and enjoy cool features, like HMR.

Instalation

# yarn
yarn add -D vite-plugin-dev-manifest

# npm
npm install -D vite-plugin-dev-manifest

Usage

Add it to your Vite config

import { defineConfig } from 'vite';
import devManifest from 'vite-plugin-dev-manifest';

export default defineConfig({
    plugins: [
        devManifest(),
        // ...
    ],

    // ...

    build: {
        // required to create a manifest file
        manifest: true,

        rollupOptions: {
            // specify your input files here, as stated in Vite config https://vitejs.dev/config/#build-rollupoptions
            input: 'src/main.ts'
        }
    }
})

Manifest file will be generated in your dist folder, specified in Vite config. So with default settings it would be something like:

{projectRoot}/dist/manifest.dev.json

Generated manifest will have following structure:

{
    // url to base folder in your local dev server
    "url": "http://localhost:3000/",
    // inputs specified in 'build.rollupOptions.input'
	"inputs": {
		"main": "src/main.ts"
	}
}

It uses your final config to find root, base path and inputs. To retrieve input URL in dev environment, concat it's value with URL like this:

{url}{inputs[input]}

Based on our example, it would be: http://localhost:3000/src/main.ts

NOTE: In manifest file, inputs field is always an object with a keys and values, even if rollupOptions.input is string or an array

Plugin ordering

vite-plugin-dev-manifest forces itself to be registered in later stages, but if more plugins uses enforce: post, it may be needed to order this plugin as the last one, f. ex.: when using along vite-plugin-symfony.

Config

Name	Type	Default	Description
manifestName	string	manifest.dev	name of the generated manifest file in dist folder
omitInputs	string[]	[]	inputs to omit in generated manifest. It is useful when you want to build some styles or scripts, but not include it in your front app
delay	number	undefined	you can delay creating of the manifest file if any of the plugins clears dist folder
clearOnClose	boolean	true	since version 1.2.0 manifest file is being removed, when dev server is closed. To prevent this behaviour, set this flag to false

Tips

We recommend using vite-plugin-live-reload to reload site when editing your backend files. Don't worry tho, HMR still works for served assets.
