Deploy Node.js Backend on EC2 in 2025: Crypto Trading Bots Guide

🔍 Introduction: Scale Your Crypto Backend with EC2

In 2025, Node.js powers 42% of backend applications globally (Stack Overflow), and Amazon EC2 offers a scalable platform to deploy them, with free-tier t2.micro instances providing 750 hours/month. India’s crypto market is booming, with CoinDCX reporting a 30% surge in trading volume (X: @cryptozone_x). EC2 is perfect for hosting crypto trading bots or blockchain APIs, offering low-latency in the ap-south-1 (Mumbai) region at ₹0.80/hour. This guide walks you through deploying a Node.js backend on EC2, tailored for Indian crypto enthusiasts, with steps, use cases, and tips to optimize costs. Let’s get started!

🚀 Step-by-Step: Deploying Node.js on EC2

EC2 provides virtual servers for Node.js apps. Here’s how to deploy an Express.js backend for a crypto trading bot.

1. Launch EC2 Instance

- Name: “NodeJS-Crypto-Backend”

- AMI: Amazon Linux 2 (free-tier).

- Type: t2.micro.

- Key Pair: Create “crypto-key.pem” and secure it (`chmod 400 crypto-key.pem`).

- Network: Enable public IP, allow SSH (port 22), HTTP (port 80), TCP (port 3000).

- Storage: 8 GB SSD.

Launch and note the public IP (e.g., 54.123.45.67).

2. Connect via SSH

Run: `ssh -i crypto-key.pem ec2-user@` and update: `sudo yum update -y`.

3. Install Node.js

Install nvm and Node.js 18:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash\nsource ~/.bashrc\nnvm install 18

Verify: `node -v` (e.g., v18.20.4).

4. Set Up Crypto App

Create an Express app:

mkdir crypto-app && cd crypto-app\nnpm init -y\nnpm install express axios

Add `index.js` for a Bitcoin price API:

const express = require("express");\nconst axios = require("axios");\nconst app = express();\napp.use(express.json());\napp.get("/price", async (req, res) => {\n  const { data } = await axios.get("https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=inr");\n  res.json({ bitcoin_inr: data.bitcoin.inr });\n});\napp.listen(3000, () => console.log("Crypto API on port 3000"));

Test: `node index.js` and visit `http://:3000/price`.

5. Deploy with PM2

Install PM2: `npm install -g pm2` and run:

pm2 start index.js --name crypto-app\npm2 startup\npm2 save

6. Optional - Nginx Proxy

Install Nginx: `sudo yum install nginx -y; sudo systemctl start nginx; sudo systemctl enable nginx`. Configure `/etc/nginx/nginx.conf` to proxy port 3000 to 80:

server {\n  listen 80;\n  server_name ;\n  location / {\n    proxy_pass http://localhost:3000;\n    proxy_http_version 1.1;\n    proxy_set_header Upgrade $http_upgrade;\n    proxy_set_header Connection "upgrade";\n    proxy_set_header Host $host;\n    proxy_cache_bypass $http_upgrade;\n  }\n}

Restart: `sudo systemctl restart nginx`. Access: `http://`.
