@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

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.

buildTargetOptions

object: object

Default: {}

Additional options to pass into the build target.

runBuildTargetDependencies

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').

waitUntilTargets

Array<string>

Default: []
