What is Angular build?

Angular is a TypeScript-based web application framework. It is a complete rewrite from the team that built AngularJS.

Angular build

Angular build uses a command ng build to build a new project of type “application” or “library”. When building libraries, the builder only invokes the ts-config, configuration, and watch options.

The application builder uses the Webpack build tool with default configuration options specified in the workspace configuration file (angular.json) or with a named alternative configuration.

Whenever a project is created using the command-line interface, a production configuration is created by default.

Syntax

ng build <project> [options]

The <project> parameter refers to the name of the project. It is a required parameter.

[options] refers to the various options offered by build that the user can utilize.

Below are a few options and their descriptions from the official documentation:

--allowed-common-js-dependencies
	
// A list of CommonJS packages that are allowed to be used without a build time warning.

--aot	
// Build using Ahead of Time compilation.

--base-href	
// Base url for the application being built.

--build-optimizer	
// Enables '@angular-devkit/build-optimizer' optimizations when using the 'aot' option.

--common-chunk	
// Use a separate bundle containing code that is used across multiple bundles.
