This is a tutorial on how to create a Go server. This tutorial is a work in progress and will be updated as I continue to work on it. If you would like to see the code, you can find my respository on Github, here.

Make sure you have Node installed

You can download and install Go from the official website here.

Initialize your project

First, we need to create a new NodeJS project. We can do this by running the following command in our terminal:

npm init -y

Install dependencies

Next, we need to install the necessary dependencies for our project. We will need the following packages:

• express
• nodemon
• dotenv

npm install express nodemon dotenv

Create a server

Next, we need to install the necessary dependencies for our project. We will need the following packages: express nodemon dotenv

project-folder/server.js

import dotenv from "dotenv";
import express from "express";
// Import required modules

// Create an Express application
dotenv.config();
const app = express();

// Define a route handler for the root URL
app.get("/", (req, res) => {
  res.send("Hello, World!");
});

// Define the port number
const port = process.env.PORT || 3000;

// Start the server
app.listen(port, () => {
  console.log(`Server is running on http://localhost:${port}`);
});

Create a .env file

Next, we need to create a .env file in the root directory of our project. This file will contain the configuration settings for our server.

project-folder/.env

PORT=5000
