Top 3 Best Hosting For MERN Stack and How They Operate 2023

In this post, we are going to discuss the Best Hosting For MERN Stack applications and their use in your projects.

What is MERN Stack?

MERN stands for MongoDB, Express, React, and Node; the four key technologies that make up the stack.

MERN Stack is a full stack, following the traditional three-tier architectural pattern, with the frontend display tier (React.js), the application tier (Express.js and Node.js), and lastly the database tier (MongoDB).

Each of these four remarkable technologies provides an end-to-end framework for the developers to work to develop software applications.

MERN Stack components and how they operate

Best Hosting For MERN Stack

React.js is the top tier of the MERN Stack, which is the client side of your application. Express.js and Node.js make up the next (middle) tier, they are for your server side, and MongoDB is for your database and it’s the bottom tier of the MERN Stack.

JSON documents, created in the React.js frontend are sent to the Express.js server, where they are processed and stored directly in MongoDB for later retrieval.

In a nutshell, a user interacts with the ReactJS UI components on the frontend of the application in the browser, the frontend is served by the application’s backend in a server through ExpressJS running on top of NodeJS.

If there’s any data change request from a user, it is sent to the NodeJS-based Express server, which captures data from the MongoDB database, and returns that data to the frontend of the application, which is then presented to the user.

Let’s look at the components in more detail below:

#1. MongoDB 

Best Hosting For MERN Stack

MongoDB is a highly scalable and flexible document database for querying and indexing. It stores data in flexible, JSON-like documents, with fields that can vary from document to document and changeable data structure.

MongoDB is free, highly available and easy to use. It provides built-in horizontal scaling and geographic distribution. It also has Ad hoc queries, indexing, and real-time aggregation which enable you to access and analyze your data.

How MongoDB works in MERN Stack?

If your application stores any data, for instance, content, comments, user profiles, uploads, events, etc., then you’ll definitely need MongoDB because it is easy to work with and works well will React, Express and Node.

#2. Express & Node JS

These two, the middle level of the MERN Stack work hand in hand; that is, the Express.js framework runs inside a Node.js server.

Express.js or simply Express is a server-side web framework designed for building web applications and APIs with Node.js. With Express, developers do not need to worry about building a backend from scratch for any application in Node.js. It allows developers the freedom to structure their code how they choose instead of forcing a particular code structure

Node.js is an open-source, cross-platform JavaScript runtime library and environment used to run web applications outside the client’s browser. It is used by developers to create server-side web applications, and it is perfect for data-intensive applications because it uses an asynchronous, event-driven model.

How they work in MERN Stack

When you make XML HTTP Requests (XHRs) or GETs or POSTs from your React.js (your frontend), you can connect to Express.js functions which power your application. These functions then use MongoDB’s Node.js drivers, either via callbacks or by using promises, to access and update data in your MongoDB database.

#3. React

Best Hosting For MERN Stack

React.js is the top tier of the MERN stack, and it works on the frontend of your application. React.js is a declarative JavaScript framework for creating dynamic client-side applications in HTML. 

It enables you to build complex interfaces through simple components, connect them to data on your backend server, and render them as HTML.

React handles stateful, data-driven interfaces with minimal code and minimal pain, and it has great support for forms, error handling, events, lists, and more.

Now that we have a deeper understanding of MERN Stack and how it works, let’s look at the best hosting to use with it.

Best Hosting Platforms for MERN Stack

So, you’ve built an awesome application with MERN Stack and now you are ready to share it with the world. Basically, you need to put it behind a simple URL and make it accessible to everyone over the internet. To achieve this, you need to choose the best hosting platform to use for your app.

To choose your hosting service, make sure to do some basic server programming to make sure your custom solution works the way you want it to.

Because your MERN stack needs a Node.js runtime and MongoDB, it would be a good idea to use a cloud server like AWS EC2 instance or DigitalOcean droplet, especially if you are working on a small or medium-sized project. 

1. AWS EC2 Best Hosting for Mern Stack

AWS (Amazon Web Services) is a comprehensive and broadly adopted cloud platform, offering over 200 fully featured services from data centres globally. It is used by millions of customers—including startups, large enterprises, and leading government agencies to lower costs, become more agile and innovate faster.

The Amazon Elastic Compute Cloud (Amazon EC2) works in the AWS cloud to provide scalable computing capacity. Using Amazon EC2 eliminates your need to invest in hardware, meaning you can develop and deploy applications faster. You can use Amazon EC2 to launch as many virtual servers as you need, configure security and networking, and manage storage. 

Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes in popularity, hence reducing your need to forecast traffic.

How do I host a MERN stack?

To host your MERN Stack project on AWS EC2, all you need to do is:

  1. Create a new Ubuntu Server on AWS EC2
  2. Connect local Terminal to Ubuntu EC2 instance via SSH
  3. Setup and install Nodejs, MongoDB, PM2, NGINX
  4. Deploy backend  API
  5. Deploy a frontend API using React
  6. Configure NGINX to server APIS; the Node.JS API and React frontend
  7. Test MERN Stack App in a browser

2. DigitalOcean Hosting for Mern Stack

Best Hosting For MERN Stack

DigitalOcean is a cloud hosting provider that offers developers cloud computing services and Infrastructure as a Service (IaaS). Developers can deploy their projects on DigitalOcean in seconds with favourable pricing and scalability.

DigitalOcean is popular with open-source developers, and it simplifies cloud computing so that builders can spend more time creating software that changes the world.

To deploy DigitalOcean’s IaaS environment, a developer must launch a private virtual machine (VM) instance, which the company calls a droplet. DigitalOcean Droplets are comparable to Amazon Elastic Compute Cloud or Azure instances, but they do not support Microsoft Windows instances.

  1. Create a new DigitalOcean droplet and Login via SSH
  2. Install NodeJS and npm
  3. Create a folder for the project on the Droplet
  4. Clone your GitHub repository
  5. Install dependencies and test the app
  6. Setup PM2 process manager to keep your app running
  7. Setup UFW Firewall
  8. Install and configure NGINX
  9. Expose your app to the outside world using NGINX as a reverse proxy

Tip: If you are to choose between DigitalOcean and AWS EC2 for your hosting platform, please take note of the following:

DigitalOcean is more suitable for organizations with smaller applications whereas AWS is better suited for large applications. 

DigitalOcean only supports Linux, it does not have native Windows OS support. Therefore, if an organization needs a cloud platform for Windows, AWS would be the better choice. 

Because DigitalOcean is an IaaS, a user has to manage the service on their own. With AWS on the other hand, the provider manages everything but the application and data. 

DigitalOcean offers physical security in its data centers, AWS on the other hand, offers security tools that enable users to detect threats and monitor unusual APIs and any other activity. 

DigitalOcean is cheaper than AWS. DigistalOcean plans start at $0.007 per hour, whereas with AWS, the cheapest on-demand EC2 instance (EC2 t2.micro) costs $0.0116 per hour.

If DigitalOcean and AWS EC2 are not going to work for you, here are a couple of other platforms you can use to deploy your MERN Stack project or application.
