Setting up a basic Node.js server with Express to create a REST API is like building a house. Each component needs to be in place for the house to stand strong and serve its purpose. In this article, we’ll guide you through the steps needed to construct your very own server.

Features

• Express
• REST API

Requirements

Before we embark on this journey, ensure you have the following tools installed:

• Node & npm
• Git

Installation Steps

1. Clone the repository: git clone git@github.com:rwieruch/node-express-server-rest-api.git
2. Navigate into the project directory: cd node-express-server-rest-api
3. Install dependencies: npm install
4. Start the server: npm start
5. Optionally, include .env in your .gitignore file for environment variables.

GET Routes

Once your server is running, you can visit http://localhost:3000 to access these routes:

• /messages
• /messages1
• /users
• /users1

Beyond GET Routes

To further interact with the API, you can use CURL or Postman. Think of CURL as a simple mail carrier, delivering requests to your server, while Postman is like a full-fledged postal service, helping you manage multiple deliveries with ease.

CURL Commands

Create a message:

curl -X POST -H "Content-Type:application/json" http://localhost:3000/messages -d '{"text":"Hi again, World"}'

Delete a message:

curl -X DELETE -H "Content-Type:application/json" http://localhost:3000/messages1

Using Postman

To interact with the REST API using Postman:

• Create a message:
  • URL: http://localhost:3000/messages
  • Method: POST
  • Body: raw + JSON (application/json)
  • Body Content: {"text": "Hi again, World"}
• Delete a message:
  • URL: http://localhost:3000/messages1
  • Method: DELETE

Troubleshooting

If you encounter any issues, here are some troubleshooting tips to help you get back on track:

• Ensure your Node.js environment is properly set up and running.
• Check that the required packages were installed correctly with no errors.
• Review the console for error messages that could guide you in fixing possible issues.
• If you’re having connectivity issues with your server, ensure that the correct port (3000) is open and not blocked.
