@nrwl/angular

What is @nrwl/angular?

@nrwl/angular is a set of tools and libraries for building Angular applications and libraries within a monorepo. It is part of the Nx suite, which provides powerful, extensible dev tools for monorepos, enabling developers to manage multiple projects and libraries in a single repository.

What are @nrwl/angular's main functionalities?

Generate Angular Applications

This command generates a new Angular application within the monorepo. It sets up the necessary files and configurations to get started with a new Angular project.

nx generate @nrwl/angular:application my-app

Generate Angular Libraries

This command generates a new Angular library within the monorepo. Libraries can be shared across multiple applications, promoting code reuse and modularity.

nx generate @nrwl/angular:library my-lib

Run Angular Application

This command serves the specified Angular application, starting a development server and enabling live reloading for a smooth development experience.

nx serve my-app

Build Angular Application

This command builds the specified Angular application for production, optimizing the output for deployment.

nx build my-app

Test Angular Application

This command runs the unit tests for the specified Angular application, ensuring code quality and correctness.

nx test my-app

Other packages similar to @nrwl/angular

angular-cli

The Angular CLI is a command-line interface tool that helps to automate the development workflow of Angular applications. It provides similar functionalities to @nrwl/angular, such as generating applications and libraries, serving applications, and running tests. However, it is not specifically designed for monorepos and does not offer the same level of integration and tooling for managing multiple projects within a single repository.

lerna

Lerna is a tool for managing JavaScript projects with multiple packages. It optimizes the workflow around managing multi-package repositories with git and npm. While Lerna is not specific to Angular, it can be used in conjunction with Angular projects to manage monorepos. However, it lacks the Angular-specific generators and integrations provided by @nrwl/angular.

nx

Nx is a set of extensible dev tools for monorepos, which includes support for Angular, React, and other frameworks. While @nrwl/angular is a part of the Nx suite specifically tailored for Angular, Nx itself provides a broader set of tools and capabilities for managing monorepos, including advanced caching, dependency graph visualization, and more.

What is Nx?

🔎 Nx is a set of Angular CLI power-ups for modern development.

Nx Helps You

Use Modern Tools

Using Nx, you can add Cypress, Jest, Prettier, and Nest into your dev workflow. Nx sets up these tools and allows you to use them seamlessly. Nx fully integrates with the other modern tools you already use and love.

Build Full-Stack Applications

With Nx, you can build full-stack applications using Angular and Node.js frameworks such as Nest and Express. You can share code between the frontend and the backend. And you can use the familiar ng build/test/serve commands to power whole dev experience.

Develop Like Google

With Nx, you can develop multiple full-stack applications holistically and share code between them all in the same workspace. Nx provides advanced tools which help you scale your enterprise development. Nx helps enforce your organization’s standards and community best practices.

A la carte

Most importantly, you can use these power-ups a la carte. Just want to build a single Angular application using Cypress? Nx is still an excellent choice for that.

Does it replace Angular CLI?

Nx is not a replacement for Angular CLI. An Nx workspace is an Angular CLI workspace.

• You run same ng build, ng serve commands.
• You configure your projects in angular.json.
• Anything you can do in a standard Angular CLI project, you can also do in an Nx workspace.

Getting Started

Creating an Nx Workspace

Using npx

npx create-nx-workspace myworkspace

Using npm init

npm init nx-workspace myworkspace

Using yarn create

yarn create nx-workspace myworkspace

Adding Nx to an Existing Angular CLI workspace

If you already have a regular Angular CLI project, you can add Nx power-ups by running:

ng add @nrwl/schematics

Creating First Application

Unlike the CLI, an Nx workspace starts blank. There are no applications to build, serve, and test. To create one run:

ng g application myapp

The result will look like this:

<workspace name>/

All the files that the CLI would have in a new project are still here, just in a different folder structure which makes it easier to create more applications and libraries in the future.

Serving Application

Run ng serve myapp to serve the newly generated application!

You are good to go!
