Installation

Keep Nx Package Versions In Sync

Make sure to install the @nx/vite version that matches the version of nx in your repository. If the version numbers get out of sync, you can encounter some difficult to debug errors. You can fix Nx version mismatches with this recipe.

In any Nx workspace, you can install @nx/vite by running the following command:

This will install the correct version of @nx/vite.

  • vite.config.js
  • vite.config.ts
  • vite.config.mjs
  • vite.config.mts
  • vite.config.cjs
  • vite.config.cts
  • vitest.config.js
  • vitest.config.ts
  • vitest.config.mjs
  • vitest.config.mts
  • vitest.config.cjs
  • vitest.config.cts

View Inferred Tasks

To view inferred tasks for a project, open the project details view in Nx Console or run nx show project my-project --web in the command line.

@nx/vite Configuration

The @nx/vite/plugin is configured in the plugins array in nx.json.

nx.json
1{ 2 "plugins": [ 3 { 4 "plugin": "@nx/vite/plugin", 5 "options": { 6 "buildTargetName": "build", 7 "previewTargetName": "preview", 8 "testTargetName": "test", 9 "serveTargetName": "serve", 10 "serveStaticTargetName": "serve-static" 11 } 12 } 13 ] 14} 15
Nx 15 and lower use @nrwl/ instead of @nx/
  • The buildTargetName, previewTargetName, testTargetName, serveTargetName and serveStaticTargetName options control the names of the inferred Vite tasks. The default names are build, preview, test, serve and serve-static.

Using @nx/vite

Generate a new project using Vite

You can generate a React application or library or a Web application that uses Vite.js. The @nx/react:app, @nx/react:lib and @nx/web:app generators accept the bundler option, where you can pass vite. This will generate a new application configured to use Vite.js, and it will also install all the necessary dependencies, including the @nx/vite plugin.

To generate a React application using Vite.js, run the following:

1nx g @nx/react:app my-app --bundler=vite 2
Nx 15 and lower use @nrwl/ instead of @nx/

To generate a React library using Vite.js, run the following:

1nx g @nx/react:lib my-lib --bundler=vite 2
Nx 15 and lower use @nrwl/ instead of @nx/

To generate a Web application using Vite.js, run the following:

1nx g @nx/web:app my-app --bundler=vite 2
Nx 15 and lower use @nrwl/ instead of @nx/

Modify an existing React or Web project to use Vite.js

You can use the @nx/vite:configuration generator to change your React or Web project to use Vite.js. This generator will modify your project's configuration to use Vite.js, and it will also install all the necessary dependencies, including the @nx/vite plugin..

You can read more about this generator on the @nx/vite:configuration generator page.
