@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

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.

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 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"

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"

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!
