ng serve

ng serve [project] [--[option]=[value]]
ng s

Build the application and start a web server.

Alias for the command:

ng run [project]:serve

[project] — the name of the project to build. Can be an application or a library.


By default for ng serve CLI uses builder dev-server.

A builder runs with default configuration options specified in the workspace configuration file (angular.json) or with a named alternative configuration.

The configuration options generally correspond to the command options. You can override individual configuration defaults by specifying the corresponding options on the command line. The command can accept option names given in either dash-case or camelCase. Note that in the configuration file, you must specify names in camelCase.

Some additional options can only be set through the configuration file, either by direct editing or with the ng config command.

Default false

--configuration#

A named build target, as specified in the configurations section of angular.json. Each named target is accompanied by a configuration of option defaults for that target. Setting this explicitly overrides the --prod flag.
