What is the purpose of the angular.json file in an Angular project?

The angular.json file holds the configuration for how your project is built, tested, and served, including things like which files to include in the build, environment specific settings, and build output locations. The CLI reads this file whenever you run commands like ng build or ng serve.

{
  "projects": {
    "my-app": {
      "architect": {
        "build": { "options": { "outputPath": "dist/my-app" } }
      }
    }
  }
}
