Step 1 : Creating Account On Deta!.

Creating A Account On Deta Is As Simple As Writing A Hello World App On Express, Lol!!. Just Go To Deta Web & Sign Up There, It Will Look Like Something Below!!.

After Signing Up You Will Get A Verification Mail On Your Inbox Just Click The Link And Verify Your Account

After Verification Click On Sign In And Login To Your Account!!. Yay!, You have Completed The First Step :)

Step 2 : Getting Project Id & Key!.

After Verification & Signing In, Deta Will Automatically Create Your First Project Called default And The Project Key Will Be Shown By Default After Signing In First Time To Your Account As Like Image Below!!.

You Will Have To Copy That Project Key And Id And Paste It In Notepad Because It Will Be Used Further!!.

Yay!, You Completed The Second Step Too! Nice :)

Step 4 : Creating Deta Micro & Express App

Go To Terminal And Type deta new --node expressapp To Create A New Micro With NodeJS Configuration And Name As expressapp, Now cd To expressapp And Open It In VS Code Or Any Code Editor!.

It Will Already Contain A Express App In index.js. Just Edit It A Little Bit, I Have Attached My Code Below!, Also Deta Does Not Listen On Ports, Just Write module.exports = app Instead Of app.listen(port)

// Dependencies
const express = require('express');
const app = express();

app.get('/', (req, res) => res.send({ message: "Hello World" }));

// Export app
module.exports = app

Also You Can Add Your Whole Code In index.js And Just Install Dependencies You Have Used In Your App, Here I Have Only Used express, So I Will Type npm i express In Terminal!.

Now Go To Terminal And Type deta deploy To Deploy Your App

After Deploying Go To Deta Web And Under Micros Section You Will Get Your App, Just Click That And Go To The URL It Shows For Your Deployed App!.

You Can Visit The URL and See Our Express App Is Live Now!!

You Can Also Change Domain Name In Domains Section, But You Have To Explore It Yourself!
