This PR fixes an issue introduced when we removed `/nx-api` pages: https://github.com/nrwl/nx/pull/31453. Most of the old `/nx-api/<plugin>` URLs should now go to `/technologies/<plugin>/introduction`, since those pages contain what was on the previous "overview" pages. The only exception are places where we explicitly link to `.../api/{generators,executors,migrations}` URLs, and the following three blog posts that we want users to land on the API index. - https://github.com/nrwl/nx/blob/master/docs/blog/2022-03-29-the-react-cli-you-always-wanted-but-didnt-know-about.md?plain=1#L132 (https://nx.dev/blog/the-react-cli-you-always-wanted-but-didnt-know-about) - https://github.com/nrwl/nx/blob/master/docs/blog/2022-04-08-what-is-new-in-nx-13-10.md?plain=1#L245 (https://nx.dev/blog/what-is-new-in-nx-13-10) - https://github.com/nrwl/nx/blob/master/docs/blog/2022-05-02-nx-v14-is-out-here-is-all-you-need-to-know.md?plain=1#L253 (https://nx.dev/blog/nx-v14-is-out-here-is-all-you-need-to-know)

title: Node.js Plugin for Nx
|
|
description: Learn how to use the @nx/node plugin to create and manage Node.js applications and libraries in your Nx workspace, including setup, building, and testing.
|

|
|
|
|
The Node Plugin contains generators and executors to manage Node applications within an Nx workspace. It provides:
|
|
|
|
## Setting Up @nx/node
|
|
|
|
### Installation
|
|
|
|
{% callout type="note" title="Keep Nx Package Versions In Sync" %}
|
|
Make sure to install the `@nx/node` 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/node` by running the following command:
|
|
|
|
```shell {% skipRescope=true %}
|
|
nx add @nx/node
|
|
```
|
|
|
|
This will install the correct version of `@nx/node`.
|
|
|
|
## Using the @nx/node Plugin
|
|
|
|
### Creating Applications
|
|
|
|
You can add a new application with the following:
|
|
|
|
```shell
|
|
nx g @nx/node:application apps/my-new-app
|
|
```
|
|
|
|
You can run your application with `nx serve my-new-app`, which starts it in watch mode.
|
|
|
|
### Creating Libraries
|
|
|
|
Node libraries are a good way to separate features within your organization. To create a Node library run the following command:
|
|
|
|
```shell
|
|
nx g @nx/node:lib libs/my-new-lib
|
|
|
|
# If you want the library to be buildable or publishable to npm
|
|
nx g @nx/node:lib libs/my-new-lib --buildable
|
|
nx g @nx/node:lib libs/my-new-lib \
|
|
--publishable \
|
|
--importPath=@myorg/my-new-lib
|
|
```
|
|
|
|
## Using Node
|
|
|
|
### 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.
|
|
|
|
### Building Projects
|
|
|
|
Node 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.
|
|
|
|
### Application Proxies
|
|
|
|
Generating Node applications has an option to configure other projects in the workspace to proxy API requests. This can be done by passing the `--frontendProject` with the project name you wish to enable proxy support for.
|
|
|
|
```shell
|
|
nx g @nx/node:application apps/my-new-app \
|
|
--frontendProject my-react-app
|
|
```
|
|
|
|
### Debugging
|
|
|
|
Debugging is set to use a random port that is available on the system. The port can be changed by setting the port option in the `serve` target in the project.json. Or by running the serve command with `--port <number>`.
|
|
|
|
