ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@nrwl/devkit
Advanced tools
The @nrwl/devkit package is a set of utilities designed to improve the developer experience by providing tools for building, testing, and managing Angular and React projects within a monorepo setup. It is part of the Nx ecosystem, which focuses on bringing a unified approach to working with modern web technologies.
Generating Components
This feature allows developers to programmatically generate components or other files within their project. The code sample demonstrates how to use the `generateFiles` function to create a new component in a library within the monorepo.
import { generateFiles } from '@nrwl/devkit';
function generateMyComponent(tree, schema) {
generateFiles(tree, path.join(__dirname, './files'), '/libs/mylib/src/lib', {
tmpl: '',
name: schema.name
});
}
Updating JSON Configuration
This feature provides a straightforward way to update JSON files, such as `tsconfig.json` or `.eslintrc.json`, programmatically. The code sample shows how to modify the `tsconfig.base.json` to add a new path mapping for a library.
import { updateJson } from '@nrwl/devkit';
function updateTsConfig(tree) {
updateJson(tree, 'tsconfig.base.json', (json) => {
json.compilerOptions.paths['@myorg/mylib'] = ['libs/mylib/src/index.ts'];
return json;
});
}
Executing Schematic Tasks
This feature enables developers to execute tasks such as adding project configurations or formatting files. The code sample illustrates how to add a new library configuration to the workspace and then format all files according to the workspace's prettier or eslint configurations.
import { addProjectConfiguration, Tree, formatFiles } from '@nrwl/devkit';
function addMyLib(tree: Tree) {
addProjectConfiguration(tree, 'my-lib', {
root: './libs/my-lib',
projectType: 'library',
targets: {},
});
formatFiles(tree);
}
Lerna is a tool for managing JavaScript projects with multiple packages, similar to the Nx workspace concept. While Lerna focuses on multi-package repositories (monorepos), it does not provide the same level of integration for Angular and React projects or the same developer tools and utilities as @nrwl/devkit.
Yeoman is a generic scaffolding system allowing the creation of any kind of app. It provides generators for a wide variety of applications and frameworks. Compared to @nrwl/devkit, Yeoman is more flexible but lacks the specific optimizations and integrations for Angular and React projects within a monorepo setup.
🔎 Smart, Extensible Build Framework
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.
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 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.
? What to create in the new workspace (Use arrow keys)
❯ empty [an empty workspace with a layout that works best for building apps]
oss [an empty workspace with a layout that works best for open-source projects]
web components [a workspace with a single app built using web components]
angular [a workspace with a single Angular application]
