@nrwl/web

What is @nrwl/web?

@nrwl/web is a package from the Nx suite that provides tools and utilities for building web applications. It is designed to work seamlessly with the Nx workspace, offering a range of features to streamline the development process, including project generation, build optimization, and testing.

What are @nrwl/web's main functionalities?

Project Generation

This command generates a new web application within an Nx workspace. It sets up the necessary configuration and scaffolding to get started quickly.

nx generate @nrwl/web:app my-app

Build Optimization

This command builds the web application in production mode, applying various optimizations such as minification and tree-shaking to ensure the output is as efficient as possible.

nx build my-app --prod

Testing

This command runs the unit tests for the specified web application. Nx integrates with popular testing frameworks like Jest to provide a smooth testing experience.

nx test my-app

Linting

This command runs the linter on the specified web application, helping to ensure code quality and consistency across the project.

nx lint my-app

Other packages similar to @nrwl/web

create-react-app

Create React App is a popular tool for setting up a new React project with a single command. It provides a lot of the same functionality as @nrwl/web, such as project generation and build optimization, but is specifically tailored for React applications.

vue-cli

Vue CLI is a standard tooling for Vue.js development. It offers project scaffolding, build optimization, and testing capabilities similar to @nrwl/web, but is focused on Vue.js applications.

angular-cli

Angular CLI is the official command-line interface for Angular. It provides a comprehensive set of tools for generating, building, and testing Angular applications, much like @nrwl/web does for web applications in general.

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:

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!
