ng lint

Runs linting tools on Angular app code in a given project folder.

ng lint <project> [options]

ng l <project> [options]


The command takes an optional project name, as specified in the projects section of the angular.json workspace configuration file. When a project name is not supplied, executes the lint builder for all projects.

To use the ng lint command, use ng add to add a package that implements linting capabilities. Adding the package automatically updates your workspace configuration, adding a lint CLI builder. For example:

"projects": {
  "my-project": {
    "architect": {
      "lint": {
        "builder": "@angular-eslint/builder:lint",
        "options": {}


Argument Description Value Type

The name of the project to lint.



Option Description Value Type Default Value

One or more named builder configurations as a comma-separated list as specified in the "configurations" section of angular.json. The builder uses the named configurations to run the given target. For more information, see https://angular.io/guide/workspace-config#alternate-build-configurations.
