Nowadays building web and mobile applications using the MERN stack has become a popular choice. You can build single-page, user-friendly, and scalable mobile and web applications with the help of the MERN stack. However, no technology is perfect and developers should be aware of the challenges that come with MERN.
In this article, we are going to discuss some common challenges developers can face with the MERN stack and How you can overcome them.
What is MERN Stack?
The MERN stack is the popular development framework, which is a combination of four Javascript-based technologies MongoDB, Express.js, React.js, and Node.js, and designed to work together that allow developers to build a full-stack web application by using JavaScript for both front-end and back-end development.
- MongoDB: it is a NoSQL database, which is highly scalable and stores data in JSON-like format in documents.
- Express.js: is a lightweight web application framework that is built on top of Node.js which helps to manage servers and routes.
- React.js: it is a popular front-end JavaScript library that is used for developing dynamic user interfaces with reusable components.
- Node.js: it is a runtime environment that helps to run JavaScript code on the server side.
Common Challenges of MERN Stack -
MERN is a powerful and versatile toolkit for developing any mobile and web application. However, like any other technology MERN also comes with several challenges and developers should be aware of them. Here are some potential challenges of MERN:
- Learning Curve: learning each technology could be challenging because each technology comes with its own syntax and concept and requires deep understanding.
- Performance Issue: it depends heavily on JavaScript which is traditionally used for the front end, so using stacks may cause performance issues, especially when used for more complex or larger applications which can slow down.
- Security: security is a concern for many technologies. In MERN SQL injection, handling sensitive data like user authentication and brute force attacks are common.
- Maintaining Code and Reusability: it is hard to write clean and maintainable code in MERN as different teams working on front and back-end development code become cluttered and hard to maintain and update.
- Database Optimization: in MERN mongodb is used for the database of MERN, it can become inefficient as the data grows continuously. it can not handle large databases and slow down the application due to excessive read and write.
- Integrity Issue: integrating technologies like MongoDB with Express.js and React.js can be complicated. It requires careful planning and testing to maintain all components for seamless working.
- SEO Issues: MERN uses the React.js library for single-page applications and because SPA constantly loads the material it gets difficult for SEO to rank and index pages.
How Can You Overcome the Common Challenges?
We can overcome the challenges developers face during the building of mobile and web app development using the right tools, strategies and adopting best practices. Here are the solutions for the above challenges which can help you to overcome the problems.
- To overcome the problem of learning difficulty of multiple technologies you should focus on each one individually before integrating them into full stack projects.
- To solve the issue of performance bottleneck in MERN you can implement strategies like indexing, caching, asynchronous programming, code splitting, lazy loading and monitor performance of applications.
- For solving security concerns you can use input validations to ensure user input meets specific criteria, use strong authentication, and you can also make use of JWT tokens for session management. You can also set up cookie flags like HTTP.
- For maintaining code and its reusability you should always write clean codes, you can also take help of ESLint and Prettier and Split the code into modules that handle different functionality.
Conclusion
When developing dynamic web apps, the MERN (MongoDB, Express.js, React, Node.js) stack is a common choice. Notwithstanding its many advantages, the MERN stack presents many difficulties for contemporary web developers. Building blocks are common for developers; they can range from managing state management in intricate programs to guaranteeing scalability and performance improvement. But many of these issues may be avoided by using best practices including applying scalability-enhancing load balancing strategies, evaluating application performance on a frequent basis, and utilizing libraries like Redux for state management. Building strong, high-performing applications using the MERN stack requires constant improvement of coding techniques and staying current with tools and frameworks.
