Bundle your TYPO3 frontend assets with vite, a modern and flexible frontend tool. This TYPO3 extension provides a future-proof integration for vite using TYPO3's AssetCollector API. This means that you can use vite's hot reloading and hot module replacement features (and many others) in your TYPO3 projects.

This extension is inspired by typo3-vite-demo which was created by Florian Geierstanger.


Vite AssetCollector can be installed with composer:

composer req praetorius/vite-asset-collector

vite can be installed with the frontend package manager of your choice:

npm install --save-dev vite vite-plugin-auto-origin

vite-plugin-auto-origin is recommended as it simplifies configuration and daily usage of vite with TYPO3.

Getting Started

1. Vite Setup

To get things started, the extension provides a console command that generates a ready-to-use vite.config.js file:

vendor/bin/typo3 vite:config --entry 'EXT:sitepackage/Resources/Private/Main.entry.js' --outputfile ./vite.config.js

The generated configuration makes sure that vite

  • knows the location of your main JavaScript file, also known as entrypoint
  • generates a manifest.json file
  • outputs assets to a publicly accessible directory

Note that the console command is only intended as a kickstarter for your initial vite configuration file.

More Options
  • You can define multiple --entry options.
  • You can add --glob to enable pattern matching for your entrypoint paths (fast-glob required).
  • If you omit --outputfile, the file content will be outputted instead.
  • Add --no-auto-origin if you don't want to use vite-plugin-auto-origin. Note that you need to specify VITE_DEV_ORIGIN manually then.
  • --help shows all available options.

2. TYPO3 Setup

Then you can use the included ViewHelper to embed your assets. If you use the default configuration, you only need to specify your entrypoint.




<vac:asset.vite entry="EXT:sitepackage/Resources/Private/Main.entry.js" />

3. Start Developing

Development environments can be highly individual. However, if ddev is your tool of choice for local development, a few steps can get you started with a ready-to-use development environment with vite, composer and TYPO3.

Instructions for DDEV


If you use the setup as described above, no configuration should be necessary. However, you can customize almost everything to create your individual development setup:

Adjust vite dev server

The extension has two configuration options to setup the vite dev server. By default, both are set to auto, which means:

  • Dev server will only be used in Development context
  • Dev server uri will be determined automatically for environments with vite-serve for DDEV set up

You can adjust both options in your $TYPO3_CONF_VARS, for example:

// Setup vite dev server based on configuration in .env file
// TYPO3_VITE_DEV_SERVER='https://localhost:1234'
$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['vite_asset_collector']['useDevServer'] = (bool) getenv('TYPO3_VITE_DEV_SERVER');
$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['vite_asset_collector']['devServerUri'] = (string) getenv('TYPO3_VITE_DEV_SERVER');
Change location of default manifest.json

You can specify a default manifest file in the extension configuration. By default, this is set to _assets/vite/.vite/manifest.json, so it will run out-of-the-box with vite 5 if you generated your vite configuration with this extension. If you still use vite < 5, you should to change this to _assets/vite/manifest.json.

If you change the path here, please be aware that you may need to adjust your the outDir in your vite.config.js as well:

$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['vite_asset_collector']['defaultManifest'] = 'EXT:sitepackage/Resources/Public/Vite/.vite/manifest.json';

If you use the vite.config.js provided by the extension:

// Output path for generated assets
const VITE_OUTPUT_PATH = 'packages/sitepackage/Resources/Public/Vite/';

If you use your own vite.config.js:

export default defineConfig({
    // ...
    outDir: 'path/to/sitepackage/Resources/Public/Vite/',

ViewHelper Reference

asset.vite ViteHelper

The asset.vite ViewHelper embeds all JavaScript and CSS belonging to the specified vite entry using TYPO3's AssetCollector API.

  • manifest (type: string): Path to your manifest.json file. If omitted, default manifest from extension configuration will be used instead.

  • entry (type: string): Identifier of the desired vite entrypoint; this is the value specified as input in the vite configuration file. Can be omitted if manifest file exists and only one entrypoint is present.

  • devTagAttributes (type: array): HTML attributes that should be added to script tags that point to the vite dev server

  • scriptTagAttributes (type: array): HTML attributes that should be added to script tags for built JavaScript assets

  • cssTagAttributes (type: array): HTML attributes that should be added to css link tags for built CSS assets

  • priority (type: bool, default: false): Include assets before other assets in HTML

  • useNonce (type: bool, default: false): Whether to use the global nonce value

  • addCss (type: bool, default: true): If set to false, CSS files associated with the entry point won't be added to the asset collector

        type: 'text/javascript',
        async: 1
        media: 'print'

resource.vite ViteHelper

The resource.vite ViewHelper extracts the uri to one specific asset file from a vite manifest file.

  • manifest (type: string): Path to your manifest.json file. If omitted, default manifest from extension configuration will be used instead.

  • file (type: string): Identifier of the desired asset file for which a uri should be generated


This can be used to preload certain assets in the HTML <head> tag:

<f:section name="HeaderAssets">
        href="{vac:resource.vite(file: 'EXT:sitepackage/Resources/Private/Fonts/webfont.woff2')}"

Vite Assets in Yaml Files

Besides ViewHelpers, the extension includes a processor for Yaml files, which allows you to use assets generated by vite in your configuration files. This is especially useful for custom RTE presets:

            # Using the default manifest file
            - "%vite('EXT:sitepackage/Resources/Private/Css/Rte.css')%"

            # Using another manifest.json
            - "%vite('EXT:sitepackage/Resources/Private/Css/Rte.css', 'path/to/manifest.json')%"


The extension includes a custom SvgIconProvider for the TYPO3 Icon API, which allows you to register SVG icon files generated by vite. This works both in frontend and backend context.

To register a new icon, add the following to the Configuration/Icons.php file:

return [
    'site-logo' => [
        'provider' => \Praetorius\ViteAssetCollector\IconProvider\SvgIconProvider::class,
        'source' => 'assets/Image/Icon/typo3.svg',
        'manifest' => 'path/to/manifest.json', // optional, defaults to defaultManifest

Then you can use the core:icon ViewHelper to use the icon in your templates.
