Bahaa Al Zubaidi observed that the use of web applications has becoming increasingly common across businesses. It is essential to use the right technology stack when you are creating a web app. The two most popular technology stacks in use are MEAN and MERN stacks. It is important to know the differences between the two and know which suits your requirements best.

Bahaa Al Zubaidi lists out the definitions and features of MEAN and MERN stacks for the benefit of the readers.

MEAN Stack 

Mean Stack is open-source and is JavaScript based. It can be used to build dynamic applications and websites. The components of MEAN Stack include:

  • Express.js, which is a flexible open-source back end running on Node.js.
  • Node.js is a runtime JavaScript environment that helps develop scalable server-side applications.
  • MongoDB is a flexible and scalable database that stores data as a JSON file, helping to work with large datasets.

The features of MEAN stack are:

  • Uses JavaScript to help improve web app performance.
  • MongoDB helps in making database management easy.
  • It is Node.Js driven and helps in reducing website load time.
  • Its flexibility allows code transfer to another framework in an easier way.

The benefits of using MEAN stack are:

  • It covers the entire development cycle from client to server side.
  • Makes web app development smooth since it supports MVC architecture.
  • It has a pre-built suite of web app testing tools for convenience.
  • It is cost-friendly and is the ideal option for startups and SMEs.
  • Open-source technology allows for better community support.

MERN Stack 

MERN Stack is a JavaScript stack similar to MEAN that helps in building hybrid mobile apps and web apps. The components of MERN Stack include:

  • Express.js is the server-side application framework helps to build web apps on Node.js.
  • Node.js is a cross-platform JavaScript runtime environment.
  • Angular is a front-end framework for cross-platform development.
  • React is an open-source frontend JavaScript library. It helps build UI components easily.
  • MongoDB is a document-based NoSQL database manager.

The features of MERN Stack are:

  • It can run on multiple servers.
  • MERN is purely JavaScript-based and can be used to develop client and server side.
  • It has a dynamic schema allowing developers to quickly build custom apps.
  • Ensures smooth UI rendering thanks to the use of React.

The benefits of using MERN stack are:

  • It allows MVC architecture for smooth web development.
  • The in-built tool suite allows real-time testing.
  • React codes can be used on browsers as well as servers.
  • The use of JavaScript allows for end-to-end development.
  • Faster development is possible thanks to the reusable component architecture.

MEAN vs. MERN 

The main difference is that MEAN uses Angular JS while MERN uses React JS. MEAN is good for enterprise apps while MERN is suitable for smaller and niche projects. MERN is best suited if you need sophisticated UI rendering.
