Transferring ExpressJS API scripts to the Server for Deployment

After developing a basic API with ExpressJS to interact with MongoDB for CRUD operations, I successfully ran it locally using the command "npm nodemon" in the source folder. Testing it with Postman confirmed its functionality. Now, my concern is how to deploy it on the server. Our server operates on a Linux system, and I have the following line of code in my main file "server.js":

const port = process.env.PORT || 5000;
I suspect that the process.env.port variable needs to be updated to function correctly on the server?

Furthermore, I explored AWS EC2 servers, but found them to be quite overwhelming. I am seeking advice from someone to suggest a straightforward and specific solution for a beginner like myself to host my ExpressJS scripts on a server environment. Thank you.

Answer №1

If you're wondering how to launch an express app on a server, you're in the right place!

For more in-depth knowledge, head over to http://expressjs.com/ to explore best practices and other valuable information. But for now, focus on optimizing your environment and setup.

Here's what you need to remember:

  1. Ensure your express app runs on port 5000
  2. Implement clustering for your app
  3. Utilize a proxy server like Nginx for enhanced performance

Refer to this helpful tutorial (specifically Step 3 and 4) for deploying your express app on a Linux server using PM2 and Nginx.

Ultimately, your express app will operate on your chosen port (such as 5000), while Nginx handles requests on port 80 and forwards them to your express app.
