The nx npm package is a suite of powerful, extensible dev tools to help you architect, test, build, and develop your software projects. It is particularly well-suited for monorepo development, where multiple projects coexist in a single repository. Nx provides tools for project scaffolding, dependency graph analysis, affected change analysis, and more.
Project Scaffolding
This command sets up a new workspace. Nx supports many presets to scaffold applications using various frameworks like Angular, React, or Node.js.
npx create-nx-workspace@latest myworkspaceGenerating Components
Generates a new component within a specified project in the workspace. This helps maintain consistency and follows best practices.
nx generate component my-component --project=my-appRunning Tasks
Executes a specific task, such as building a project. Nx uses an executor to run tasks which can be configured for different environments.
nx run my-app:buildAffected Change Analysis
Determines which apps and libs are affected by changes to the current git branch, and performs the build task only for those.
nx affected:buildDependency Graph
Visualizes the dependency graph of the workspace, showing how projects depend on one another. This is useful for understanding the structure and ensuring that changes do not have unintended consequences.
nx dep-graphLerna is a tool for managing JavaScript projects with multiple packages, optimizing the workflow around managing multi-package repositories with git and npm. Compared to Nx, Lerna focuses more on the versioning and publishing of multi-package repositories, whereas Nx provides a broader range of tools for development and build optimization.
🔎 Extensible Dev Tools for Monorepos.
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.
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 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 instead of rebuilding or retesting the code from scratch. This, in combination with Nx’s support for distributed and incremental builds, can help teams see up to 10x reduction in build and test times.
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.
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.
