Nx CLI

What is Nx?

🔎 Smart, Fast and Extensible Build System

Nx is a smart, fast and extensible build system. It comes with first class monorepo support and powerful integrations.

Best-in-Class Support for Monorepos

Nx provides distributed graph-based task execution and computation caching.

Nx is smart. It analyzes your workspace and figures out what can be affected by every code change. That's why Nx doesn't rebuild and retest everything on every commit--it only rebuilds what is necessary .

Nx partitions commands into a graph of smaller tasks. Nx then runs those tasks in parallel, and it can even distribute them across multiple machines without any configuration.

Nx also uses a distributed computation cache. If someone has already built or tested similar code, Nx will use their results to speed up the command for everyone else.

Holistic Dev Experience Powered by an Advanced CLI and Editor Plugins

Nx helps scale your development from one team building one application to many teams building multiple frontend and backend applications all in the same workspace. When using Nx, developers have a holistic dev experience powered by an advanced CLI (with editor plugins), capabilities for controlled code sharing and consistent code generation.

Rich Plugin Ecosystem

Nx is an open platform with plugins for many modern tools and frameworks. It has support for TypeScript, React, Angular, Cypress, Jest, Prettier, Nest.js, Next.js, Storybook, Ionic among others. With Nx, you get a consistent dev experience regardless of the tools used.

Getting Started

Creating an Nx Workspace

Using npx

npx create-nx-workspace

Using npm init

npm init nx-workspace

Using yarn create

yarn create nx-workspace

The create-nx-workspace command will ask you to select a preset, which will configure some plugins and create your applications to help you get started.

? What to create in the new workspace (Use arrow keys)
❯ empty             [an empty workspace with a layout that works best for building apps]
  npm               [an empty workspace set up to publish npm packages (similar to and compatible with yarn workspaces)]
  react             [a workspace with a single React application]
  angular           [a workspace with a single Angular application]
  next.js           [a workspace with a single Next.js application]
  gatsby            [a workspace with a single Gatsby application]
  nest              [a workspace with a single Nest application]
  express           [a workspace with a single Express application]
  web components    [a workspace with a single app built using web components]
  react-express     [a workspace with a full stack application (React + Express)]
  angular-nest      [a workspace with a full stack application (Angular + Nest)]

Select the preset that works best for you.

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.
