@nx/js:node

Execute Nodejs applications.

Options can be configured in project.json when defining the executor, or when invoking it. Read more about how to configure targets and executors here: https://nx.dev/reference/project-configuration#targets.

The @nx/js:node executor runs the output of a build target. For example, an application uses esbuild (@nx/esbuild:esbuild) to output the bundle to dist/my-app folder, which can then be executed by @nx/js:node.

project.json:

"my-app": {
  "targets": {
    "serve": {
      "executor": "@nx/js:node",
      "options": {
        "buildTarget": "my-app:build"
      }
    },
    "build": {
      "executor": "@nx/esbuild:esbuild",
      "options": {
        "main": "my-app/src/main.ts",
        "output": ["dist/my-app"],
        //...
      }
    },
  }
}
Nx 15 and lower use @nrwl/ instead of @nx/

npx nx serve my-app

Examples

Using runtimeArgs, you can pass arguments to the underlying node command. For example, if you want to set --no-warnings to silence all Node warnings, then add the following to the project.json file.

"my-app": {
  "targets": {
    "serve": {
      "executor": "@nx/js:node",
      "options": {
        "runtimeArgs": ["--no-warnings"],
        //...
      },
    },
  }
}
Nx 15 and lower use @nrwl/ instead of @nx/

Options

buildTarget

Required

string

The target to run to build you the app.

args

Array<string>

Default: []

Extra args when starting the app.

debounce

number

Default: 500

Delay in milliseconds to wait before restarting. Useful to batch multiple file changes events together. Set to zero (0) to disable.

host

string

Default: localhost

The host to inspect the process on.

inspect

oneOf [string, boolean]

Default: inspect

Ensures the app is starting with debugging.

port

runtimeArgs

Array<string>

Default: []

Extra args passed to the node process.

watch

boolean

Default: true

Enable re-building when files change.

watchIgnore

Array<string>

Default: []

List of glob patterns to ignore for file watching.

buildTargetOptions

object: object

Default: {}

Additional options to pass into the build target.

waitUntilTargets

Array<string>

Default: []

The targets to run before starting the node app.

watchRunBuildTargetDependencies

boolean

Default: false

Whether to run dependencies before running the build. Set this to true if the project does not build libraries from source (e.g. 'buildLibsFromSource: false').
