What's new in Angular CLI 1.4?

Angular CLI 1.4.0 is out with some nice new features!

If you want to upgrade to 1.4.0 without pain (or to any other version, BTW), I have created a Github project to help: angular-cli-diff. Choose the version you’re currently using (1.2.1 for example), and the target version (1.4.0 for example), and it gives you a diff of all files created by the CLI: angular-cli-diff/compare/1.2.1…1.4.0. You have no excuse for staying behind anymore!

Let’s see what new features we have!


The Google team has created schematics, a Yeoman-like generator. Angular CLI will now use this new tool to generate the application skeleton and the components, services, pipes… All the blueprints are now bundled in schematics/@angular and have been removed from the CLI itself.

Really interesting as it opens the possibility to have other blueprints than the official ones! This is a feature that other frameworks also have (like Vue CLI or Ember CLI).

We can expect to see new “schematics” for Angular CLI really soon, for example some oriented for server-side rendering apps, or mobile apps, or progressive apps, or native apps, etc.

The CLI now has an option to specify the blueprint you want to use when you generate a project:

ng new --collection my-custom-schematics project-name

You can of course define your own schematics, but we did not give it a try yet.

Serve path

A new option for ng serve is available to specify a path where you want the application to be served in dev:

ng serve --serve-path hello

will serve the application at http://localhost:4200/hello. This is a simple way to configure it, even if you could do the same with the --base-href and --deploy-url flags.

Missing translation strategy

If you are using the i18n support of Angular, you can specify directly from the CLI the strategy you want to adopt when a translation is missing:

ng build --aot --locale fr --i18n-file src/i18n/messages.fr.xlf --missing-translation error

The --missing-translation error flag is available for the serve and build commands, and accepts the values error, warning or ignore.

Scripts sourcemaps and minifications

The scripts that were added via the scripts array in .angular-cli.json were not minified and had no sourcemaps. This is now resolved.
