The Nx plugin for Vite and Vitest.
Vite.js is a build tool that aims to provide a faster and leaner development experience for modern web projects.
Why should you use this plugin?
- Instant dev server start
- Lightning fast Hot-Module Reloading
- Fast builds using Vite.
- Vite-powered tests with smart and instant watch mode
Read more about Vite and Vitest in the Vite documentation.
Setting up Vite
You can create a new workspace that uses Vite with one of the following commands:
- Generate a new monorepo with a Web Components app set up with Vite
npx create-nx-workspace@latest --preset=web-components
- Generate a new standalone React app set up with Vite
npx create-nx-workspace@latest --preset=react-standalone
Add Vite to an existing workspace
To add the Vite plugin to an existing workspace, run the following:
npm install -D @nrwl/vite
Initialize Vite.js
After you install the plugin, you need to initialize Vite.js. You can do this by running the init
executor. This executor will make sure to install all the necessary dependencies.
nx g @nrwl/vite:init
You will notice that the executor will ask you of the framework you are planning to use. This is just to make sure that the right dependencies are installed. You can always install manually any other dependencies you need.
Generate an application using Vite
You can generate a React or a Web application that uses Vite.js. The @nrwl/react:app
and @nrwl/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.
To generate a React application using Vite.js, run the following:
nx g @nrwl/react:app my-app --bundler=vite
To generate a Web application using Vite.js, run the following:
nx g @nrwl/web:app my-app --bundler=vite
Modify an existing React or Web application to use Vite.js
You can use the @nrwl/vite:configuration
generator to change your React or Web application to use Vite.js. This generator will modify your application's configuration to use Vite.js, and it will also install all the necessary dependencies.
You can read more about this generator on the @nrwl/vite:configuration
generator page.
Set up your apps to use Vite.js manually
You can use the @nrwl/vite:dev-server
and the @nrwl/vite:build
executors to serve and build your applications using Vite.js. To do this, you need to make a few adjustments to your application.
Check the example:/mandarini/nx-recipes/tree/feat/react-vite-recipe/vite-example
1. Change the executors in your project.json
The serve
target
In your app's project.json
file, change the executor of your serve
target to use @nrwl/vite:dev-server
and set it up with the following options:
//...
"my-app": {
"targets": {
//...
"serve": {
"executor": "@nrwl/vite:dev-server",
"defaultConfiguration": "development",
"options": {
"buildTarget": "my-app:build",
"port": 4200,
},
"configurations": {
...
}
},
}
}
You do not have to set the port
here, necessarily. You can also specify the port in the vite.config.ts
file (see Step 2 below). The same goes for all other Vite.js options that you can find the Vite.js documentation. All these can be added in your vite.config.ts
file.
The build
target
In your app's project.json
file, change the executor of your build
target to use @nrwl/vite:build
and set it up with the following options:
//...
"my-app": {
"targets": {
//...
"build": {
"executor": "@nrwl/vite:build",
...
"options": {
"outputPath": "dist/apps/my-app"
},
"configurations": {
...
}
},
}
}
You can specify more options in the vite.config.ts
file (see Step 2 below).
2. Configure Vite.js
TypeScript paths
You need to use the vite-tsconfig-paths
plugin to make sure that your TypeScript paths are resolved correctly in your monorepo.
React plugin
If you are using React, you need to use the @vitejs/plugin-react
plugin.
How your vite.config.ts
looks like
Add a vite.config.ts
file to the root of your app. If you are not using React, you can skip adding the react
plugin, of course.
// eg. apps/my-app/vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import ViteTsConfigPathsPlugin from 'vite-tsconfig-paths';
export default defineConfig({
plugins: [
react(),
ViteTsConfigPathsPlugin({
root: '../../',
}),
],
});
Make sure the root
path in the ViteTsConfigPathsPlugin
options is correct. It should be the path to the root of your workspace.
In that config file, you can configure Vite.js as you would normally do. For more information, see the Vite.js documentation.
Creating a root vite.config.ts
file
You can create a vite.config.ts
file to the root of your workspace, as well as at the root of each of your applications. This file is used to configure Vite. You can read more about the configuration options in the Vite documentation.
The root vite.config.ts
file can be used for all applications, and you can place in there general configurations that would apply for all your apps using Vite in your workspace. The application-specific vite.config.ts
files can be used to override the root configuration, or, for example, import framework-specific plugins (eg. the '@vitejs/plugin-react'
for React apps). The application-specific configuration files extend (using mergeConfig
) the root configuration file. You can adjust this behavior to your needs.
So, if you are using a root vite.config.ts
file, you should adjust your code as follows:
// <workspace-root>vite.config.ts
import { defineConfig } from 'vite';
export default defineConfig({
plugins: [],
});
and then in your app's vite.config.ts
file:
// eg. apps/my-app/vite.config.ts
import { mergeConfig } from 'vite';
import baseConfig from '../../vite.config';
import react from '@vitejs/plugin-react';
import ViteTsConfigPathsPlugin from 'vite-tsconfig-paths';
export default mergeConfig(baseConfig, {
plugins: [
react(),
ViteTsConfigPathsPlugin({
root: '../../',
}),
],
});
3. Move index.html
and point it to your app's entrypoint
First of all, move your index.html
file to the root of your app (eg. from apps/my-app/src/index.html
to apps/my-app/index.html
).
Then, add a module script
tag pointing to the main.tsx
(or main.ts
) file of your app:
...
<body>
<div id="root"></div>
<script type="module" src="src/main.tsx"></script>
</body>
</html>
4. Add a public
folder
You can add a public
folder to the root of your app. You can read more about the public folder in the Vite.js documentation.
myorg/
├── apps/
│ ├── my-app/
│ │ ├── src/
│ │ │ ├── app/
│ │ │ ├── assets/
│ │ │ ├── ...
│ │ │ └── main.tsx
│ │ ├── index.html
│ │ ├── public/
| . | . | ├── favicon.ico
│ │ │ └── my-page.md
│ │ ├── project.json
│ │ ├── ...
│ │ ├── tsconfig.app.json
│ │ ├── tsconfig.json
│ │ └── tsconfig.spec.json
You can use the public
folder to store static assets, such as images, fonts, and so on. You can also use it to store Markdown files, which you can then import in your app and use as a source of content.
5. Adjust your app's tsconfig.json
Change your app's tsconfig.json
(eg. apps/my-app/tsconfig.json
) compilerOptions
to the following:
For React apps
...
"compilerOptions": {
"jsx": "react-jsx",
"allowJs": false,
"esModuleInterop": false,
"allowSyntheticDefaultImports": true,
"forceConsistentCasingInFileNames": true,
"isolatedModules": true,
"lib": ["DOM", "DOM.Iterable", "ESNext"],
"module": "ESNext",
"moduleResolution": "Node",
"noEmit": true,
"resolveJsonModule": true,
"skipLibCheck": true,
"strict": true,
"target": "ESNext",
"types": ["vite/client"],
"useDefineForClassFields": true
},
...
For Web apps
...
"compilerOptions": {
"target": "ESNext",
"useDefineForClassFields": true,
"module": "ESNext",
"lib": ["ESNext", "DOM"],
"moduleResolution": "Node",
"strict": true,
"resolveJsonModule": true,
"isolatedModules": true,
"esModuleInterop": true,
"noEmit": true,
"noUnusedLocals": true,
"noUnusedParameters": true,
"noImplicitReturns": true,
"skipLibCheck": true,
"types": ["vite/client"]
},
"include": ["src"],
...
You can read more about the TypeScript compiler options in the Vite.js documentation.
6. Use Vite.js!
Now you can finally serve and build your app using Vite.js:
Serve the app
nx serve my-app
or
nx run my-app:serve
Now, visit http://localhost:4200 to see your app running!
Build the app
nx build my-app
or
nx run my-app:build
