@nrwl/cli

What is @nrwl/cli?

@nrwl/cli is a command-line interface tool for Nx, a set of extensible dev tools for monorepos. It helps developers manage and scale their monorepos, providing features for code generation, project management, and more.

What are @nrwl/cli's main functionalities?

Generate Applications

This command generates a new React application within the monorepo. The @nrwl/cli tool provides schematics for various frameworks, making it easy to scaffold new projects.

nx generate @nrwl/react:app my-app

Run Tasks

This command runs a build task for the specified project. Nx provides a powerful task runner that can execute tasks in parallel, cache results, and more.

nx run my-app:build

Lint Projects

This command lints the specified project using the configured linter. Nx helps maintain code quality across the monorepo by providing consistent linting rules.

nx lint my-app

Test Projects

This command runs tests for the specified project. Nx integrates with popular testing frameworks to provide a seamless testing experience.

nx test my-app

Affected Commands

This command builds only the projects that are affected by the latest changes. Nx's affected commands help optimize CI/CD pipelines by reducing the scope of tasks to only what is necessary.

nx affected:build

Other packages similar to @nrwl/cli

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. Compared to @nrwl/cli, Lerna is more focused on package management and publishing, while Nx provides a more comprehensive set of tools for monorepo development, including code generation, task running, and more.

turbo

Turborepo is a high-performance build system for JavaScript and TypeScript codebases. It focuses on speeding up builds and tests in monorepos by leveraging caching and parallel execution. While @nrwl/cli offers a broader range of features for managing monorepos, Turborepo is specifically optimized for build performance.

rush

Rush is a scalable monorepo manager for the web, developed by Microsoft. It provides robust support for managing large monorepos, including features for incremental builds, change tracking, and more. Compared to @nrwl/cli, Rush is more focused on enterprise-scale monorepo management and build orchestration.

What is Nx?

🔎 Extensible Dev Tools for Monorepos.

Nx Helps You

Use Modern Tools

Using Nx, you can add TypeScript, 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 modern frameworks. You can share code between the frontend and the backend. And you can use the same build/test/serve commands throughout the whole dev experience.

Develop like Google, Facebook, and Microsoft

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 also helps enforce your organization’s standards and community best practices.

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

If it's your first Nx project, the command will recommend you to install @nrwl/cli globally, so you can invoke nx directly without going through yarn or npm.

Adding Nx to an Existing Angular CLI workspace

If you are an Angular user, you can also add Nx to your existing Angular CLI project by running:

ng add @nrwl/workspace

Creating First Application

By default, an Nx workspace starts blank. There are no applications to build, serve, and test. To create one, you need to add capabilities to the workspace.

To add an Angular app, run:

yarn add @nrwl/angular
nx g @nrwl/angular:app myapp # or just "nx g myapp"

npm install --save-dev @nrwl/angular
nx g @nrwl/angular:app myapp # or just "nx g myapp"

To add a React app, run:

yarn add @nrwl/react
nx g @nrwl/react:app myapp # or just "nx g myapp"

npm install --save-dev @nrwl/react
nx g @nrwl/react:app myapp # or just "nx g myapp"

To add a web components app, run:

yarn add @nrwl/web
nx g @nrwl/web:app myapp # or just "nx g myapp"

npm install --save-dev @nrwl/web
nx g @nrwl/web:app myapp # or just "nx g myapp"

If nx g fails, use: yarn nx g @nrwl/web:app myapp or npm run nx -- g @nrwl/web:app myapp.

Regardless of what framework you chose, the resulting file tree will look like this:

<workspace name>/
├── apps/
│   ├── myapp/
│   └── myapp-e2e/
├── libs/
├── tools/
├── nx.json
├── package.json
├── tsconfig.json
└── tslint.json

Serving Application

• Run nx serve myapp to serve the newly generated application!
• Run nx test myapp to test it.
• Run nx e2e myapp-e2e to run e2e tests for it.

Angular users can also run ng g/serve/test/e2e.

You are good to go!
