Introduction

This is a simple example of how to create a micro front end application using Nx and React. This example is based on the following concepts:

• Nx Workspace
• React
• Micro Front End
• Module Federation
• Webpack 5
• Data Layer (API and State Management)
• Shared UI Components (form example MUI, Ant Design, Chakra, Shadcn etc.)

Getting Started

To get started, you need to create nx-workspace and then create a new React application with pnpm. You can do this by running the following commands:

🔗 See pnpm documentation. Download

pnpx create-nx-workspace

Creating Nx Workspace steps like below:

• Where would you like to create your workspace? : mfe-tutorial

  • mfe-tutorial

• Which stack do you want to use? : I choose React

  • None: Configures a TypeScript/JavaScript project with minimal structure. (default)
  • React: Configures a React application with your framework of choice. ✅
  • Vue: Configures a Vue application with your framework of choice.
  • Angular: Configures a Angular application with modern tooling.
  • Node: Configures a Node API application with your framework of choice.

• What framework would you like to use? : I choose None

  • None I only want react and react-dom in my workspace. ✅
  • Next.js [ https://nextjs.org/ ]
  • Remix [ https://remix.run/ ]
  • Expo [ https://expo.io/ ]
  • React Native [ https://reactnative.dev/ ]

• Integrated monorepo, or standalone project? : I choose Int. Monorepo

  • Int. Monorepo Nx creates a monorepo that contains multiple projects. ✅
  • Standalone Nx creates a single project and makes it fast.

• Application name : mfe-tutorial

  • mfe-tutorial

• Which bundler would you like to use? : I choose Webpack

  • Vite [ https://vitejs.dev/ ]
  • Webpack [ https://webpack.js.org/ ] ✅
  • Rspack [ https://www.rspack.dev/ ]

• Test runner to use for end to end (E2E) tests : I choose Playwright

  • None .
  • Cypress [ https://www.cypress.io/ ]
  • Playwright [ https://playwright.dev/ ] ✅

• Default stylesheet format : I choose Tailwind CSS

  • CSS
  • SASS(.scss) [ https://sass-lang.com ]
  • LESS [ https://lesscss.org ]
  • tailwind [ https://tailwindcss.com ] ✅
  • styled-components [ https://styled-components.com ]
  • emotion [ https://emotion.sh ]
  • styled-jsx [ https://www.npmjs.com/package/styled-jsx ]

• Do you want Nx Cloud to make your CI fast? : I choose Yes, configure Nx Cloud for GitHub Actions

  • Yes, enable Nx Cloud
  • Yes, configure Nx Cloud for GitHub Actions
  • Yes, configure Nx Cloud for Circle CI
  • Skip for now

🎉 Congratulations! You have successfully created your Nx workspace.

Nx Console Extension for VSCode

Nx Console is a Visual Studio Code extension used for developing projects created with Nx Workspace. With this extension, tasks such as development, testing, and building projects can be easily performed.

You can install the Nx Console extension in Visual Studio Code or search for "Nx Console" in VS Code and install it.

 Setting up Eslint, Prettier and Husky Configuration

• First, you need to install the following packages:

pnpm add -D eslint-config-airbnb eslint-config-airbnb-typescript eslint-plugin-prettier eslint-plugin-simple-import-sort

Package installation steps like below:

• eslint-config-airbnb : Airbnb's ESLint config.
• eslint-config-airbnb-typescript : Airbnb's ESLint config for TypeScript.
• eslint-plugin-prettier : ESLint plugin for Prettier formatting.

• eslint-plugin-simple-import-sort : ESLint plugin for sorting imports.

• Modify the .eslintrc.json file as follows:

• Now, you can add VSCode Settings for Eslint auto fix and format on save. Add the following settings to .vscode/settings.json or .vscode/settings.json file.

  "editor.codeActionsOnSave": {
    "source.fixAll": "explicit",
    "source.fixAll.eslint": "explicit"
  },
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "typescript",
    "typescriptreact"
  ],
  "eslint.format.enable": true

• Add the lint script to the package.json file.

{
  "scripts": {
    "lint": "pnpm exec nx run-many --target=lint --all"
  }
}

• Add the husky package for pre-commit hooks.

pnpm add --save-dev husky

• Run the following command to create a new husky configuration file.

pnpm exec husky init

• Modify the .husky/pre-commit file as follows:

#!/bin/sh
. "$(dirname "$0")/_/husky.sh"

pnpm run lint

🎉 Congratulations! You have successfully set up Eslint, Prettier and Husky configuration with Nx Workspace.
