MERN stack development is a popular choice among web application development options due to the combination of loose technologies which includes the likes of MongoDB, Express, React and Node.js. Likewise, there can be difficulties with the MERN stack development technique just as any development difficulty which as complex is.
Controlling State
The MERN stack is a stack consisting of multiple languages that can be difficult to develop but it is still considered an easy one to develop. The data manipulation is one of the biggest problems while using the React framework that is a part of the MERN stack. This is because it is difficult to manage an application's state in a centralized fashion. A structure called the implementation of state management libraries which provide a centralized store for the application's state needs to be used to overcome this problem, such as Redux or MobX.
Increasing Application Scale
Scalability of the application is yet another negative aspect that is often covered during MERN stack development process. Using the app becomes trickier and the maintenance fo it as it increases in size and grows to be more intricate. Functioning issues like longer loads times and higher server overload may be produced by this. We recommend applying the load balancing methods and the customer base situation could be eased by using query cache or any content delivery network.
Including Outside Services
Challenging a process of work with external services such as services of payment gateways and social media APIs integration may be really difficult when developing the MERN stack. These APIs are often complex in nature, and hence the daunting task if integrating them with the application arises. Hence, rather than creating the Passport-like templates, setting it up and spending time on them, one can use a third-party library like Passport, which offers an easy API for integrating third-party services into the application, around this issue.
Security Issues
Acting as a symptom of web applications' exposure to security threats such as XSN and injection attacks of SQL, security is one of the main goals when building MERN stack. The use of smart practices, like the HTTPS one which provides the communication layer in an encrypted form, the user input validation, and also, a framework for security, such as Express, is recommended to solve this problem.
Identifying and fixing problems
The fact that the MERN stack is growing as more complex and difficult to manage, the debugging and the troubleshooting also become the more challenging barriers which I need to handle. A debugging tool, such as React DevTools or the similar browser based tools, could help to some extend when trying to avert this problem. The pro-active approach to troubleshooting, like logging and error tracking tools could help further.
