Express.js Environment Setup
Before we can start building Express applications, we need to set up our development environment. This includes installing Node.js, npm, and a code editor. Don't worry – it's simpler than it sounds!
What You Need
- Node.js: The runtime environment that runs JavaScript on the server.
- npm: Node Package Manager – comes with Node.js, used to install packages.
- Code Editor: VS Code (recommended), Sublime, or any text editor.
- Terminal/Command Prompt: To run Node.js commands.
Setting up your environment is like preparing your kitchen before cooking – once it's ready, you can focus on creating amazing things!
Step 1: Install Node.js
1. Go to nodejs.org
2. Download the LTS (Long Term Support) version – it's more stable
3. Run the installer and follow the instructions
4. Restart your computer after installation
Step 2: Verify Installation
Open your terminal/command prompt and type:
node --versionYou should see something like
v18.12.0 (version may vary).Check npm as well:
npm --versionThis shows the npm version (e.g.,
8.19.2).Step 3: Install VS Code (Recommended)
1. Go to code.visualstudio.com
2. Download for your operating system
3. Install and open VS Code
4. Install useful extensions:
- ES7+ React/Redux/React-Native snippets
- Prettier – Code formatter
- npm Intellisense
Step 4: Create Project Folder
Open terminal and run:
mkdir express-appcd express-appTwo Minute Drill
- Install Node.js from nodejs.org (LTS version recommended).
- Verify installation with `node --version` and `npm --version`.
- VS Code is the recommended editor with helpful extensions.
- Create a project folder to organize your code.
