Creating an Nx Workspace

A workspace contains your Angular application (or applications) and any supporting libraries you create. It is a monorepo for your application domain.

With Angular CLI you can add different types of projects to a single workspace (by default you can add applications and libraries). This is great, but is not sufficient to enable the monorepo-style development. Nx adds an extra layer of tooling to make this possible.

The @nrwl/schematics library contains a binary script that provides the command create-nx-workspace. That command can be used to create a new Nx Workspace:

create-nx-workspace myworkspacename

This will create a new Nx Workspace using a sandboxed environment... running the Angular CLI ng new command under the hood and using the Nx schematics collection.

Note: You can use ng new if you like, but it relies on globally installed npm packages. And we know that those can be messy. If your globally installed npm packages are in a bad shape, use the create-nx-workspace command.

Add to an Existing Angular CLI workspace

If you already started your project with the Angular CLI, you can also add Nx capabilities by running:

ng add @nrwl/schematics
