@nrwl/tao

What is @nrwl/tao?

The @nrwl/tao package is part of the Nx monorepo toolset provided by Nrwl. It provides a set of utilities for workspace management, task orchestration, and abstracts away the configuration for building and testing applications. It is designed to help developers create and maintain monorepo setups more efficiently.

What are @nrwl/tao's main functionalities?

Workspace Management

This feature allows you to read the workspace configuration file, which is useful for understanding the structure and configuration of projects within the workspace.

const { readWorkspaceJson } = require('@nrwl/tao/src/core/file-utils');
const workspaceJson = readWorkspaceJson();

Task Orchestration

This feature enables you to programmatically execute tasks such as building or testing a project within the workspace. It is useful for automating workflows and integrating with other tools.

const { runCommand } = require('@nrwl/tao/src/commands/run-command');
runCommand('build', { project: 'my-app' }, { interactive: false });

Configuration Abstraction

This feature provides utility functions to work with the workspace's root path and other configuration details, simplifying the process of setting up and maintaining a monorepo.

const { getWorkspacePath } = require('@nrwl/tao/src/utils/app-root');
const workspacePath = getWorkspacePath();

Other packages similar to @nrwl/tao

lerna

Lerna is a tool for managing JavaScript projects with multiple packages, similar to @nrwl/tao. It optimizes the workflow around managing multi-package repositories with git and npm. Lerna can also automate the versioning and publishing of packages.

yarn-workspaces

Yarn Workspaces is a feature of Yarn that allows users to set up multiple package directories within a single repository. It is similar to @nrwl/tao in that it helps manage dependencies and linking between packages in a monorepo.

What is Nx?

🔎 Extensible Dev Tools for Monorepos.

Nx Helps You

Develop like Google, Facebook, and Microsoft

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.

Use Intelligent Build System with Distributed 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 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.

Use Modern Tools

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]
  web components    [a workspace with a single app built using web components]
  angular           [a workspace with a single Angular application]
  angular-nest      [a workspace with a full stack application (Angular + Nest)]
  react             [a workspace with a single React application]
  react-express     [a workspace with a full stack application (React + Express)]
  next.js           [a workspace with a single Next.js application]

Select the preset that works best for you. You can always add plugins later.

? Workspace name (e.g., org name)     happyorg
? What to create in the new workspace web components    [a workspace with a single app built using web components]
? Application name                    myapp
? Default stylesheet format           CSS

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.

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!
