This PR removes installation instructions for Nx < 18 since it has fallen out of support window. Users can always `npm install <plugin>` as usual if they are on an unsupported Nx version, but the docs will assume `nx add` moving forward. The changes are on the plugin overview page: https://nx-dev-git-docs-remove-nx-pre-18-install-nrwl.vercel.app/nx-api

title: Web Plugin for Nx
|
|
description: Learn how to use the @nx/web plugin to create and manage Web Component applications and libraries in your Nx workspace, including testing and building.
|
|
---
|
|
|
|
The Nx Plugin for Web Components contains generators for managing Web Component applications and libraries within an Nx workspace. It provides:
|
|
|
|
- Integration with libraries such as Jest, Cypress, and Storybook.
|
|
- Scaffolding for creating buildable libraries that can be published to npm.
|
|
- Utilities for automatic workspace refactoring.
|
|
|
|
## Setting Up @nx/web
|
|
|
|
### Generating a new Workspace
|
|
|
|
To create a new workspace with React, run `npx create-nx-workspace@latest --preset=web-components`.
|
|
|
|
### Installation
|
|
|
|
{% callout type="note" title="Keep Nx Package Versions In Sync" %}
|
|
Make sure to install the `@nx/web` 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](/recipes/tips-n-tricks/keep-nx-versions-in-sync).
|
|
{% /callout %}
|
|
|
|
In any Nx workspace, you can install `@nx/web` by running the following command:
|
|
|
|
```shell {% skipRescope=true %}
|
|
nx add @nx/web
|
|
```
|
|
|
|
This will install the correct version of `@nx/web`.
|
|
|
|
## Using the @nx/web Plugin
|
|
|
|
### Creating Applications
|
|
|
|
You can add a new application with the following:
|
|
|
|
```shell
|
|
nx g @nx/web:app apps/my-new-app
|
|
```
|
|
|
|
The application uses no framework and generates with web components. You can add any framework you want on top of the default setup.
|
|
|
|
To start the application in development mode, run `nx serve my-new-app`.
|
|
|
|
{% callout type="note" title="React" %}
|
|
If you are looking to add a React application, check out the [React plugin](/nx-api/react).
|
|
{% /callout %}
|
|
|
|
### Creating Libraries
|
|
|
|
To create a generic TypeScript library (i.e. non-framework specific), use the [`@nx/js`](/nx-api/js) plugin.
|
|
|
|
```shell
|
|
nx g @nx/js:lib libs/my-new-lib
|
|
|
|
# If you want the library to be publishable to npm
|
|
nx g @nx/js:lib libs/my-new-lib \
|
|
--publishable \
|
|
--importPath=@myorg/my-new-lib
|
|
```
|
|
|
|
## Using Web
|
|
|
|
### Testing Projects
|
|
|
|
You can run unit tests with:
|
|
|
|
```shell
|
|
nx test my-new-app
|
|
nx test my-new-lib
|
|
```
|
|
|
|
Replace `my-new-app` with the name or your project. This command works for both applications and libraries.
|
|
|
|
You can also run E2E tests for applications:
|
|
|
|
```shell
|
|
nx e2e my-new-app-e2e
|
|
```
|
|
|
|
Replace `my-new-app-e2e` with the name or your project with `-e2e` appended.
|
|
|
|
### Building Projects
|
|
|
|
React applications can be build with:
|
|
|
|
```shell
|
|
nx build my-new-app
|
|
```
|
|
|
|
And if you generated a library with `--buildable`, then you can build a library as well:
|
|
|
|
```shell
|
|
nx build my-new-lib
|
|
```
|
|
|
|
The output is in the `dist` folder. You can customize the output folder by setting `outputPath` in the project's `project.json` file.
|
|
|
|
The application in `dist` is deployable, and you can try it out locally with:
|
|
|
|
```shell
|
|
npx http-server dist/apps/my-new-app
|
|
```
|
|
|
|
The library in `dist` is publishable to npm or a private registry.
