- Node.js and npm: Sails.js requires Node.js installed. You can download it from the official Node.js website.
- Basic command line experience: You should be comfortable running commands in your terminal or Command Prompt.
- Internet connection: To download npm packages during installation.
Step 1: Verify Node.js and npm Installation
Open your terminal and run:

You should see version numbers for both. If not installed, download and install Node.js from its official site linked above.
Step 2: Install Sails.js Globally

Step 4: Create a New Sails.js Project
Navigate to the directory where you want your project and run:
sails new myApp
This creates a new Sails.js app named “myApp” with default files and dependencies configured.
Step 5: Start Your Sails.js App
Change directory into the app folder and lift the server:
cd myApp
sails lift
Your app will start running on http://localhost:1337. Open this URL in your browser to see the default welcome page.
Troubleshooting Tips

sudoon Linux/Mac or Command Prompt as Administrator on Windows. - Port conflicts: If port 1337 is in use, you can specify another port when lifting the app:
sails lift --port=PORT_NUMBER. - Firewall issues: Ensure your firewall allows connections to the app port.
