MERN Stack Tutorial | Become an Expert MERN Stack Developer

MERN Stack Tutorial for Beginners | MERN Stack (MongoDB, Express, React, Node.js)

This video is based on MERN Stack Developer Full Course. MERN Stack Developer tutorial will help you learn the latest technical advancements in MERN Stack and guide you with the fundamentals based on current IT standards. This tutorial will help you with critical skills, tips, and tips to become an expert MERN Stack Developer.


How to Use MERN Stack: A Complete Guide

This tutorial will show you how to build a full-stack MERN application—in this case, an employee database—with the most current tools available. Before you begin, make sure that you are familiar with Node.js and React.js basics and have Node and Create React App installed. You will also need access to the MongoDB Atlas database for this tutorial. The full code is available on this GitHub repo.

What is the MERN Stack?

The MERN stack is a web development framework made up of the stack of MongoDB, Express.js, React.js, and Nodejs. It is one of the several variants of the MEAN stack. MERN stack visualized When you use the MERN stack, you work with React to implement the presentation layer, Express and Node to make up the middle or application layer, and MongoDB to create the database layer.

In this MERN stack tutorial, we will utilize these four technologies to develop a basic application that is able to record the information of employees and then display it using a React.

How to Get Started with the MERN Stack

To get started, you will need to do the following:

Install Node
To install Node, go to https://nodejs.org/en/ and download either the LTS version or the current version.

Have or Install a Code Editor
You can use any code editor of your choice for this tutorial. However, for the sake of demonstration, we will be using VS Code editor with the plugin prettier and vscode icons.

Setting Up the Project

(Feel free to code along or to download the full code from this GitHub repo.)

MERN lets us create full-stack solutions. So, to leverage its full potential, we will be creating a MERN stack project. For this project, we will create both a back end and a front end. The front end will be implemented with React and the back end will be implemented with MongoDB, Node, and Express. We will call the front end client and the back end server.

Let’s start by creating an empty directory: mern. This folder will hold all our files after we create a new project. Then we will create a React app—client—in it.

mkdir mern
cd mern
npx create-react-app client

Then, we create a folder for the back end and name it server.

mkdir server

We will jump into the server folder that we created previously and create the server. Then, we will initialize package.json using npm init.

cd server
npm init -y

We will also install the dependencies.

npm install mongodb express cors dotenv

The command above uses a couple of keywords:

  • mongodb command installs MongoDB database driver that allows your Node.js applications to connect to the database and work with data.
  • express installs the web framework for Node.js. (It will make our life easier.)
  • cors installs a Node.js package that allows cross origin resource sharing.
  • dotenv installs the module that loads environment variables from a .env file into process.env file. This lets you separate configuration files from the code.

We can check out installed dependencies using the package.json file. It should list the packages along with their versions.

After we have ensured that dependencies were installed successfully, we create a file called server.js with the following code.:

mern/server/server.js

const express = require("express");
const app = express();
const cors = require("cors");
require("dotenv").config({ path: "./config.env" });
const port = process.env.PORT || 5000;
app.use(cors());
app.use(express.json());
app.use(require("./routes/record"));
// get driver connection
const dbo = require("./db/conn");
 
app.listen(port, () => {
  // perform a database connection when server starts
  dbo.connectToServer(function (err) {
    if (err) console.error(err);
 
  });
  console.log(`Server is running on port: ${port}`);
});

Here, we are requiring express and cors to be used. const port process.env.port will access the port variable from the config.env we required.

Connecting to MongoDB Atlas

It’s time to connect our server to the database. We will use MongoDB Atlas as the database. MongoDB Atlas is a cloud-based database service that provides robust data security and reliability. MongoDB Atlas provides a free tier cluster that never expires and lets you access a subset of Atlas features and functionality.

Follow the Get Started with Atlas guide to create an account, deploy your first cluster, and locate your cluster’s connection string.

Now that you have the connection string, go back to the ‘server’ directory and create a ‘config.env’ file. There, assign the connection string to a new ATLAS_URI variable. Once done, your file should look similar to the one below. Replace <username> and the <password> with your database username and password.

mern/server/config.env

ATLAS_URI=mongodb+srv://<username>:<password>@sandbox.jadwj.mongodb.net/employees?retryWrites=true&w=majority
PORT=5000

Create a folder under the server directory—db—and inside it, a file—conn.js. There we can add the following code to connect to our database.

mern/server/db/conn.js

const { MongoClient } = require("mongodb");
const Db = process.env.ATLAS_URI;
const client = new MongoClient(Db, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});
 
var _db;
 
module.exports = {
  connectToServer: function (callback) {
    client.connect(function (err, db) {
      // Verify we got a good "db" object
      if (db)
      {
        _db = db.db("employees");
        console.log("Successfully connected to MongoDB."); 
      }
      return callback(err);
         });
  },
 
  getDb: function () {
    return _db;
  },
};

Server API Endpoints

Database done. Server done. Now it's time for the Server API endpoint. Let's start by creating a routes folder and adding record.js in it. Navigate back to your “server” directory and create the new directory and file:

cd ../server
mkdir routes
touch routes/record.js

The routes/record.js file will also have the following lines of code in it.

mern/server/routes/record.js

const express = require("express");
 
// recordRoutes is an instance of the express router.
// We use it to define our routes.
// The router will be added as a middleware and will take control of requests starting with path /record.
const recordRoutes = express.Router();
 
// This will help us connect to the database
const dbo = require("../db/conn");
 
// This help convert the id from string to ObjectId for the _id.
const ObjectId = require("mongodb").ObjectId;
 
 
// This section will help you get a list of all the records.
recordRoutes.route("/record").get(function (req, res) {
 let db_connect = dbo.getDb("employees");
 db_connect
   .collection("records")
   .find({})
   .toArray(function (err, result) {
     if (err) throw err;
     res.json(result);
   });
});
 
// This section will help you get a single record by id
recordRoutes.route("/record/:id").get(function (req, res) {
 let db_connect = dbo.getDb();
 let myquery = { _id: ObjectId( req.params.id )};
 db_connect
     .collection("records")
     .findOne(myquery, function (err, result) {
       if (err) throw err;
       res.json(result);
     });
});
 
// This section will help you create a new record.
recordRoutes.route("/record/add").post(function (req, response) {
 let db_connect = dbo.getDb();
 let myobj = {
   name: req.body.name,
   position: req.body.position,
   level: req.body.level,
 };
 db_connect.collection("records").insertOne(myobj, function (err, res) {
   if (err) throw err;
   response.json(res);
 });
});
 
// This section will help you update a record by id.
recordRoutes.route("/update/:id").post(function (req, response) {
 let db_connect = dbo.getDb(); 
 let myquery = { _id: ObjectId( req.params.id )}; 
 let newvalues = {   
   $set: {     
     name: req.body.name,    
     position: req.body.position,     
     level: req.body.level,   
   }, 
  }
});
 
// This section will help you delete a record
recordRoutes.route("/:id").delete((req, response) => {
 let db_connect = dbo.getDb();
 let myquery = { _id: ObjectId( req.params.id )};
 db_connect.collection("records").deleteOne(myquery, function (err, obj) {
   if (err) throw err;
   console.log("1 document deleted");
   response.json(obj);
 });
});
 
module.exports = recordRoutes;

If you run the application at this point, you will get the following message in your terminal as the connection establishes.

> node server.js

Server is running on port: 5000
Successfully connected to MongoDB.

That’s it for the back end. Now, we will start working on the front end.

Setting Up the React Application

As we have already set up our React application using the create-react-app command, we can navigate to the client folder and check our React application code. Navigate to client folder

Let’s flesh out the application, but before we do, we need to install two additional dependencies that will be used in our project. Open a new terminal emulator, navigate to the “client” directory, and install bootstrap and react-router-dom.

npm install bootstrap react-router-dom

bootstrap lets you quickly deploy a template and components for your new web application without having to do everything from scratch. And, the react-router-dom installs React router components for web applications. Make sure your server application is still running!

Setting Up the React Router

Let's start by emptying the src folder and adding two new files in it: index.js and App.js.

rm src/**/*
touch src/index.js src/App.js

Inside src/index.js, we add the following code:

mern/client/src/index.js

import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import { BrowserRouter } from "react-router-dom";

ReactDOM.render(
  <React.StrictMode>
    <BrowserRouter>
      <App />
    </BrowserRouter>
  </React.StrictMode>,
  document.getElementById("root")
);

We have used BrowserRouter to keep our UI in sync with the URL. BrowserRouter helps with seamless transitions while switching between components. Basically, it will only reload/refresh the component that needs to be changed instead of refreshing/reloading the entire page. Though BrowserRouter is not a necessity, it is a must if you want your app to be responsive.

Creating Components

After adding the code to index.js files, we will create a components folder inside src. For each component we create, we will add a new .js file inside the components folder. In this case, we will add create.js, edit.js, navbar.js, and recordList.js.

mkdir src/components
(cd src/components &&
touch create.js edit.js navbar.js recordList.js)

A snapshot of each file would look like the following.

create.js

The following code will serve as a creating component for our records. Using this component, users can create a new record. This component will submit a create command to our server.

mern/client/src/components/create.js

import React, { useState } from "react";
import { useNavigate } from "react-router";
 
export default function Create() {
 const [form, setForm] = useState({
   name: "",
   position: "",
   level: "",
 });
 const navigate = useNavigate();
 
 // These methods will update the state properties.
 function updateForm(value) {
   return setForm((prev) => {
     return { ...prev, ...value };
   });
 }
 
 // This function will handle the submission.
 async function onSubmit(e) {
   e.preventDefault();
 
   // When a post request is sent to the create url, we'll add a new record to the database.
   const newPerson = { ...form };
 
   await fetch("http://localhost:5000/record/add", {
     method: "POST",
     headers: {
       "Content-Type": "application/json",
     },
     body: JSON.stringify(newPerson),
   })
   .catch(error => {
     window.alert(error);
     return;
   });
 
   setForm({ name: "", position: "", level: "" });
   navigate("/");
 }
 
 // This following section will display the form that takes the input from the user.
 return (
   <div>
     <h3>Create New Record</h3>
     <form onSubmit={onSubmit}>
       <div className="form-group">
         <label htmlFor="name">Name</label>
         <input

           className="form-control"
           id="name"
           value={form.name}
           onChange={(e) => updateForm({ name: e.target.value })}
         />

           id="position"
           value={form.position}
           onChange={(e) => updateForm({ position: e.target.value })}
         />
       </div>
       <div className="form-group">
         <div className="form-check form-check-inline">
           <input
             className="form-check-input"
             type="radio"
             name="positionOptions"
             id="positionIntern"
             value="Intern"
             checked={form.level === "Intern"}
             onChange={(e) => updateForm({ level: e.target.value })}
           />
           <label htmlFor="positionIntern" className="form-check-label">Intern</label>
         </div>
         <div className="form-check form-check-inline">
           <input
             className="form-check-input"
             type="radio"
             name="positionOptions"
             id="positionJunior"
             value="Junior"
             checked={form.level === "Junior"}
             onChange={(e) => updateForm({ level: e.target.value })}
           />
           <label htmlFor="positionJunior" className="form-check-label">Junior</label>
         </div>
         <div className="form-check form-check-inline">
           <input
             className="form-check-input"
             type="radio"
             name="positionOptions"
             id="positionSenior"
             value="Senior"
             checked={form.level === "Senior"}
             onChange={(e) => updateForm({ level: e.target.value })}
           />
           <label htmlFor="positionSenior" className="form-check-label">Senior</label>
         </div>
       </div>
       <div className="form-group">

           className="btn btn-primary"
         />
       </div>
     </form>
   </div>
 );
}

edit.js

The following code will serve as an editing component for our records. It will use a similar layout to the create component and will eventually submit an update command to our server.

mern/client/src/components/edit.js

import React, { useState, useEffect } from "react";
import { useParams, useNavigate } from "react-router";
 
export default function Edit() {
 const [form, setForm] = useState({
   name: "",
   position: "",
   level: "",
   records: [],
 });
 const params = useParams();
 const navigate = useNavigate();
 
 useEffect(() => {
   async function fetchData() {
     const id = params.id.toString();
     const response = await fetch(`http://localhost:5000/record/${params.id.toString()}`);
 
     if (!response.ok) {
       const message = `An error has occurred: ${response.statusText}`;
       window.alert(message);
       return;
     }
 
     const record = await response.json();
     if (!record) {
       window.alert(`Record with id ${id} not found`);
       navigate("/");
       return;
     }
 
     setForm(record);
   }
 
   fetchData();
 
   return;
 }, [params.id, navigate]);
 
 // These methods will update the state properties.
 function updateForm(value) {
   return setForm((prev) => {
     return { ...prev, ...value };
   });
 }
 
 async function onSubmit(e) {
   e.preventDefault();
   const editedPerson = {
     name: form.name,
     position: form.position,
     level: form.level,
   };
 
   // This will send a post request to update the data in the database.
   await fetch(`http://localhost:5000/update/${params.id}`, {
     method: "POST",
     body: JSON.stringify(editedPerson),
     headers: {
       'Content-Type': 'application/json'
     },
   });
 
   navigate("/");
 }
 
 // This following section will display the form that takes input from the user to update the data.
 return (
   <div>
     <h3>Update Record</h3>
     <form onSubmit={onSubmit}>
       <div className="form-group">

           id="name"
           value={form.name}

           id="position"
           value={form.position}
           onChange={(e) => updateForm({ position: e.target.value })}

           className="btn btn-primary"
         />
       </div>
     </form>
   </div>
 );
}

recordList.js

The following code will serve as a viewing component for our records. It will fetch all the records in our database through a GET method.

mern/client/src/components/recordList.js

import React, { useEffect, useState } from "react";
import { Link } from "react-router-dom";
 
const Record = (props) => (
 <tr>
   <td>{props.record.name}</td>
   <td>{props.record.position}</td>
   <td>{props.record.level}</td>
   <td>
     <Link className="btn btn-link" to={`/edit/${props.record._id}`}>Edit</Link> |
     <button className="btn btn-link"
       onClick={() => {
         props.deleteRecord(props.record._id);
       }}
     >
       Delete
     </button>
   </td>
 </tr>
);
 
export default function RecordList() {
 const [records, setRecords] = useState([]);
 
 // This method fetches the records from the database.
 useEffect(() => {
   async function getRecords() {
     const response = await fetch(`http://localhost:5000/record/`);
 
     if (!response.ok) {
       const message = `An error occurred: ${response.statusText}`;
       window.alert(message);
       return;
     }
 
     const records = await response.json();
     setRecords(records);
   }
 
   getRecords();
 
   return;
 }, [records.length]);
 
 // This method will delete a record
 async function deleteRecord(id) {
   await fetch(`http://localhost:5000/${id}`, {
     method: "DELETE"
   });
 
   const newRecords = records.filter((el) => el._id !== id);
   setRecords(newRecords);
 }
 
 // This method will map out the records on the table
 function recordList() {
   return records.map((record) => {
     return (
       <Record
         record={record}
         deleteRecord={() => deleteRecord(record._id)}
         key={record._id}
       />
     );
   });
 }
 
 // This following section will display the table with the records of individuals.
 return (
   <div>
     <h3>Record List</h3>
     <table className="table table-striped" style={{ marginTop: 20 }}>
       <thead>
         <tr>
           <th>Name</th>
           <th>Position</th>
           <th>Level</th>
           <th>Action</th>
         </tr>
       </thead>
       <tbody>{recordList()}</tbody>
     </table>
   </div>
 );
}

navbar.js

In the navbar.js component, we will create a navigation bar that will link us to the required components using the following code.

mern/client/src/components/navbar.js

import React from "react";
 
// We import bootstrap to make our application look better.
import "bootstrap/dist/css/bootstrap.css";
 
// We import NavLink to utilize the react router.
import { NavLink } from "react-router-dom";
 
// Here, we display our Navbar
export default function Navbar() {
 return (
   <div>
     <nav className="navbar navbar-expand-lg navbar-light bg-light">
       <NavLink className="navbar-brand" to="/">
       <img style={{"width" : 25 + '%'}} src="https://d3cy9zhslanhfa.cloudfront.net/media/3800C044-6298-4575-A05D5C6B7623EE37/4B45D0EC-3482-4759-82DA37D8EA07D229/webimage-8A27671A-8A53-45DC-89D7BF8537F15A0D.png"></img>
       </NavLink>
       <button

         data-target="#navbarSupportedContent"
         aria-controls="navbarSupportedContent"
         aria-expanded="false"
         aria-label="Toggle navigation"
       >
         <span className="navbar-toggler-icon"></span>
       </button>
 
       <div className="collapse navbar-collapse" id="navbarSupportedContent">
         <ul className="navbar-nav ml-auto">
           <li className="nav-item">
             <NavLink className="nav-link" to="/create">
               Create Record
             </NavLink>
           </li>
         </ul>
       </div>
     </nav>
   </div>
 );
}

Now, we add the following to the src/App.js file we created earlier.

mern/client/src/App.js

import React from "react";
 
// We use Route in order to define the different routes of our application
import { Route, Routes } from "react-router-dom";
 
// We import all the components we need in our app
import Navbar from "./components/navbar";
import RecordList from "./components/recordList";
import Edit from "./components/edit";
import Create from "./components/create";
 
const App = () => {
 return (
   <div>
     <Navbar />
     <Routes>
       <Route exact path="/" element={<RecordList />} />
       <Route path="/edit/:id" element={<Edit />} />
       <Route path="/create" element={<Create />} />
     </Routes>
   </div>
 );
};
 
export default App;

Connecting the Front End to the Back End

We have completed creating components. We also connected our React app to the back end using fetch. fetch provides cleaner and easier ways to handle http requests. fetch is used in create.js, edit.js, and recordList.js as they handle http requests. In create.js, we appended the following code to the onSubmit(e) block. When a POST request is sent to the create URL, fetch will add a new record to the database.

// This function will handle the submission.
 async function onSubmit(e) {
   e.preventDefault();
 
   // When a post request is sent to the create url, we'll add a new record to the database.
   const newPerson = { ...form };
 
   await fetch("http://localhost:5000/record/add", {
     method: "POST",
     headers: {
       "Content-Type": "application/json",
     },
     body: JSON.stringify(newPerson),
   })
   .catch(error => {
     window.alert(error);
     return;
   });
 
   setForm({ name: "", position: "", level: "" });
   navigate("/");
 }

Similarly, in edit.js, we appended the following code to the onSubmit(e) block.

async function onSubmit(e) {
   e.preventDefault();
   const editedPerson = {
     name: form.name,
     position: form.position,
     level: form.level,
   };
 
   // This will send a post request to update the data in the database.
   await fetch(`http://localhost:5000/update/${params.id}`, {
     method: "POST",
     body: JSON.stringify(editedPerson),
     headers: {
       'Content-Type': 'application/json'
     },
   });
 
   navigate("/");
 }

We also placed the following block of code to edit.js beneath the constructor block.

useEffect(() => {
   async function fetchData() {
     const id = params.id.toString();
     const response = await fetch(`http://localhost:5000/record/${params.id.toString()}`);
 
     if (!response.ok) {
       const message = `An error has occurred: ${response.statusText}`;
       window.alert(message);
       return;
     }
 
     const record = await response.json();
     if (!record) {
       window.alert(`Record with id ${id} not found`);
       navigate("/");
       return;
     }
 
     setForm(record);
   }
 
   fetchData();
 
   return;
 }, [params.id, navigate]);

Lastly, we have recordList.js. recordList.js fetches the records from the database, so we will be using fetch's get method to retrieve records from the database. To achieve this, we added the following lines of code above the recordList() function in recordList.js.

useEffect(() => {
   async function getRecords() {
     const response = await fetch(`http://localhost:5000/record/`);
 
     if (!response.ok) {
       const message = `An error occurred: ${response.statusText}`;
       window.alert(message);
       return;
     }
 
     const records = await response.json();
     setRecords(records);
   }
 
   getRecords();
 
   return;
 }, [records.length]);
 
 // This method will delete a record
 async function deleteRecord(id) {
   await fetch(`http://localhost:5000/${id}`, {
     method: "DELETE"
   });
 
   const newRecords = records.filter((el) => el._id !== id);
   setRecords(newRecords);
 }

After closing everything, to start the app, follow these steps.

  • Ensure that the server app is still running. If it’s not, start by executing the following command in the server/ directory:
node server.js
  • Go back to the client directory and run the command:
npm start

This is what the landing page of the record component will look like after we added two records for “Richard” and “Billy” via the “Create Record” button.

Sample record landing page

This is what the screen that lets you add an employee will look like. Sample create new record page

Bothe MEAN and MERN are full stack frameworks with Java coded components. The difference is that MEAN uses Angular JS while MERN uses the React JS developed by Facebook. Both aids developers to make reactive and intuitive UI. To understand which stack is the better one, we need to understand the underlying differences between them.

This is image title

DIFFERENCES BETWEEN MEAN AND MERN
MEAN: Components include Mongo DB, Angular JS, Express, and Node.
MERN: Components include Mongo DB, React JS, Express, and Node.
MEAN: JavaScript development stack.
MERN: Open source JavaScript library.
MEAN: Uses Typescript language.
MERN: Uses JavaScript and JSX.
MEAN: Copnent based architecture.
MERN: None.
MEAN: Regular DOM.
MERN: Virtual DOM.
MEAN: Steep learning curve.
MERN: Better documentation.
MEAN: Bidirectional data flow.
MERN: Unidirectional dataflow.
Both tech has high class features and immense functionality. The slight upper hand that MERN enjoys is in the learning curve. MERN is easier to grasp because the learning curve differs between Angular JS and React JS. Let us take a deeper dive into the benefits of MEAN and MERN stacks to understand the power of each of these stacks fully.

BENEFITS OF MEAN AND MERN
MEAN STACK
All types of applications can be developed easily.
Various plug ins and widgets have compatibility with this stack. For development that has a stricter time frame, this comes in handy.
The functionality skyrockets due to the availability of plug ins.
Developers enjoy community support since the framework is open source.
Real time testing is possible with the built-in tools.
A single language is used for back end and front end. This increases coordination and gets applications to respond faster.
MERN STACK
Front end and back end are covered by a single coding script.
The entire process can be completed using only JAVA and JSON.
Seamless development through the MVC architecture.
Real time testing through built-in tools.
Runs on an open source community and the source code can be easily modified.
According to Hacker Rank development skill report, 30% of developers went with Angular JS while 26% stayed with React JS. The report also mentions that 30% of the programmers wanted to learn React JS and 35.9% of developers prefer to develop using React JS, thus MERN stands slightly above MEAN when it comes to popularity.

As far as we know, in terms of ease of understanding and popularity, MERN is at the forefront now. Let us take a detailed comparison to understand who will win the race in 2021.

MEAN vs MERN : A DETAILED COMPARISON
Scalability, Security: Both MEAN and MERN are equally secure. However, in terms of scalability, MERN is at the forefront.

MVC: For enterprise level apps, a complete architecture needs to be maintained. MEAN is the better option for this.
UI: For an advanced and simple UI, MERN is the go-to stack. MERN facilitates user interaction.
CRUD: For CRUD (create, read, update, delete), MERN is the ideal stack. The React JS handles data changes quickly and has a good user interface as well.
Support: The Angular JS in MEAN supports HTTP calls and unites the back-end. Enterprise level app development will require third party.
libraries. On the other hand, React JS improves functionality through its supplementary libraries. MEAN scores slightly above in this section.
MEAN enhances the experience through the use of third party extensions while MERN would require additional configurations to do this.

In aspects of the learning curve, UI, scalability, and CRUD, MERN stack scores more than MEAN stack. However, in the aspects of community support and MVC MEAN stays ahead. In terms of security both are at par. However, the application of the stacks depend entirely on the business needs.

MEAN is more affordable, and is the first choice for startups and SMEs. Switching between clients and servers is easier. For real time web apps, MEAN is definitely the best choice. In MERN, the Virtual DOM enhances user experience and gets the developer’s work done faster. A stable code is maintained by React JS due to a unidirectional data flow. For coding for Android and IOS using JavaScript, MERN is definitely the way to go.

TAKE AWAY
Companies like Accenture, Raindrop, Vungle, Fiverr, UNIQLQ, and Sisense among others use MEAN in their tech stacks. Brands such as UberEats, Instagram, and Walmart use MERN stack. Both the stacks provide an incredible user experience. Stability and scalability can be achieved with both stacks.

From this we can conclude that enterprise level projects require MEAN over MERN. MERN makes rendering UI simpler. Both are reliable for a quick front end development.

MEAN is good for large scale application. MERN is good for faster development of smaller applications.

At Orion we have an excellent team that can help you with all your MEAN and MERN stack development needs.

Is Full-Stack Developer A Vaccine For Startups?

There's a wise old saying: "Working with a full stack developer can lead to better technology solutions." And in recent years, this saying has proven to be true for many startups.

In the last few years, we have heard a lot about full-stack developers.

We know that a full-stack developer is a person who has complete knowledge of the different layers involved in application development. Whether you are dealing with the front or back end or working in the business layer, they take care of everything with ease.

But did you wonder why a full-stack developer is so important for a startup? 

This blog will answer all such queries. So let's get started.

The Demand for Full-Stack Developers

As per a development report published recently, it was seen that there had been a 206% increase in demand for full-stack developers from 2018 to 2020. This is because more companies seek multifaceted skills. 


Full-stack developers or a full-stack development company are able to take care of all the development needs of your project. So whether it's front-end or back-end development or enterprise layer development, they are competent to work on everything. You can always hire full-stack developers for your business needs.

What can a Full-Stack Developer Do?

In terms of software development, there are front-end developers and back-end developers. Front-end developers create the interface, while backend developers design the software. 

A full-stack developer can do everything. They take care of application design, server-side scripting, client-side coding, coding, administration, database creation, and any other project development needs.

The following are the responsibilities of a full stack developer that you hire:

  • Manage web development

  • Code applications and programs

  • Solve problems

  • Coordinate with other team members and developers

  • Think about testing techniques for web applications

In short, a full-stack developer has a strong understanding of the technologies that determine how a website looks, functions, and functions. The said developer must have a working knowledge of HTML, JavaScript, CSS, PHP, Angular, Ruby, MySQL, Node, MongoDB, Apache, etc. The knowledge to work with animations and design will add a bonus point to a candidate's portfolio.

Over time, the skills required for full-stack development have expanded and evolved. Long ago, the LAMP stack included Linux, Apache, MySQL, and PHP. It is more than MEAN and beyond today. 

Currently, a typical mean stack development service provides developers who can perform front-end development using JavaScript, HTML, CSS, and other JS frameworks; for the backend, they use Express and Node, and for databases, they follow MySQL and MongoDB.

Top Reasons to Hire Full-Stack Developers

  • Effective troubleshooting

When hiring a full-stack developer, companies are always looking for candidates who are capable of solving a problem. Full-stack developers are competent to handle all aspects of the project. They prove to be a practical solution for startups that are not willing to spend more money on many developers.

  • Wide range of technology skills

The main reason companies choose full-stack developers for their projects is their potential rather than their knowledge. Over time, companies teach them the skills they want them to have. In this way, in a few years, they learn different technological skills as the company expands.

  • Executive and management skills

Companies like to have people with business experience on board. A full-stack developer has the knowledge and expertise to work on the front-end, backend, and media architecture layers. This means that they are capable of performing better than an individual front-end or backend developer.

  • Economic

As full-stack developers can develop all aspects of a project, it is not necessary to form a team of experts. They will easily handle the project without help from anyone. This will save the right amount of money for the recruiting team.

  • Faster development process

Full-stack developers know different technologies, tools, and techniques. This means that when they take the project, they will be able to complete it faster. They will spend less time discussing and collaborating with the team on the project.

Benefits of Full-Stack Developers for Startups and Small Businesses

  • Established developers

Full-stack developers have enough experience to create outstanding features for the final product, which will be able to excite the market. They have the ability to build a complete product from scratch. If you want to gain some benefits from your product, you will have to collaborate with these experts. Remember that not all developers are capable of handling the project from a 360-degree perspective.

  • Versatility

A full-stack developer is able to work equally well on the front-end and the backend of a website or application. Front-end developers write code using JavaScript, HTML, and CSS, which are able to control the appearance of the solution and how it interacts with the browser and users. Backend developers write code that connects the website or application with other content management systems. A full-stack developer is capable of handling both tasks. They are focused on meeting customer expectations and finding solutions on their own.

 

  • Vast experience

Full-stack developers take on different web projects. This has helped them gain in-depth knowledge of various technologies and the experience to find quick solutions in web and application development. Such understanding and knowledge improve the performance of the project and its reception in the market.

  • The largest photograph

The main advantage of choosing a full-stack developer for your project is that they will come up with the complete structure of the project and offer their valuable input to the project as needed. Their services go beyond project development to maintain and optimize existing solutions.

  • Upgrades

Web design plays a crucial role in whether most people love or reject a website. Full-stack developers will make sure that the website is pretty user-friendly. They keep up with trends and technological innovations. To make sure their clients get the best interactive and responsive website, the developers implement intelligent features in their projects.

  • Troubleshooting issues

Full-stack developers have complete knowledge and experience of the different stages and aspects of website development. They are skilled enough to identify problems that may arise during the development of the project. They will propose long-term solutions to ensure that the website or application works optimally based on their findings.

  • All-inclusive

In addition to leading your web project and enabling enhancements to it, full-stack developers move to the level of representing your product to stakeholders or your company at conferences. They can move quickly from one operation to another with ease, streamlining the development process.

  • Economic

If you are on a tight budget but want to create a fantastic website, then you should consider hiring full developers for the job. You can even think about having a remote full-stack developer for the project. As such, a developer is capable of handling all aspects of project development; you won't have to hire different people for the job. This will save you a lot of money.

  • Delivery time

It will be easy for developers to share responsibilities among the team and coordinate with each other for better project progress. This will result in faster delivery of the project.

  • Project ownership

When you hire full-stack developers for your project, you can be sure that they will take care of everything. Such a developer will be able to develop MVP from start to finish. If you hire a full-stack developer in the middle of the project, even then, you'll find a way to join the flow seamlessly. Such a developer will work towards quality control of the design project.

 

 

Summing Up

So these were the advantages of hiring a full-stack developer. I hope you have noted the changes that a full-stack developer can bring to the table and in your company. However, working with a full-stack developer is the best way to work with a top full-stack development company in India.

It is a good idea that full-stack development companies bring to your projects are phenomenal and groundbreaking due to the expertise and experience that full-stack development companies bring to your projects.
