Why is MERN Stack a Good Choice for Startup Apps?

The MERN stack includes various frameworks, libraries, and databases. It enables easy customer data management, job production, scheduling, invoicing, accounting, shipment, order fulfillment, and more from one platform. MERN stack web development is famous for its security, reliability, and flexibility.

If you are considering building a startup app, there’s no better option than the MERN stack. Before building your startup app, understand each component of the technology and its benefits.

MongoDB

It is a document-oriented database and stores data in JSON-like documents. MongoDB documents have dynamic schemas. It means that you can add new fields without having to rewrite the application. 

MongoDB provides robust and consistent writes and reads through application control over the replica sets. Read/write performance becomes better linearly as the nodes start adding. Replication ensures high availability by storing multiple document copies across various machines.

Developers can perform note operations parallelly on multiple modes. Developers using MongoDB need to learn a new approach to structuring data. Uber, Delivery Hero, and Lyft are some leading companies who have trusted MongoDB in the MERN stack framework.

Pros of MongoDB

  • The document-oriented database storage of MongoDB is highly scalable. Therefore, it’s ideal for applications that need real-time scalability. For instance, e-commerce websites and large social network sites can benefit from MongoDB.
  • The data gets stored in flexible documents instead of rows and columns. Therefore, developers can use JavaScript code to operate on data directly. They won’t need separate objects between the application and database layer.
  • The flexibility of working with MongoDB is unparalleled when compared to SQL databases.
  • Data is dynamic and structure-free. Therefore, documents don’t need to follow a particular structure over time.
  • Different types of data are supported by default, and several user-defined kinds are also available. It becomes easier to model complex data sets than superficial key or value-based structures.

ExpressJS

It is an open-source web application framework written in JavaScript. ExpressJS enables the creation of fast, scalable, and strong web applications. It is also known as Express and can be installed in NodeJS. It either acts as middleware or within the browser.

Express eliminates the need to write repeated server code. Several extensive features and plugins work effectively to help build fast web APIs and applications. Accenture, Twitter, and Bla Bla Car are popular use cases of ExpressJS. 

Pros of ExpressJS

  • The primary benefit of ExpressJS is the ability to use JavaScript on both the front and back end.
  • It enables developers to use JavaScript for everything. Therefore, it helps save during the MERN stack development process.
  • It is more efficient because the same language is used by both frontend and backend developers. Due to the use of one language, communication becomes easier. 
  • It brings more agility across the team. Team members can work on new ideas and deal with software changes faster.
  • JavaScript is constantly evolving and makes any new updates with it instantly reflected in Express. Therefore, it becomes easier to try out new features as they keep coming.

ReactJS

The JavaScript library built by Facebook is used for creating UI. React makes it easy to develop large applications with constant data changes. Many developers have used React without even knowing it.

Social media platforms like Facebook and Instagram rely heavily on ReactJS. Some other popular applications of React include Yahoo Weather, Amazon, and Netflix. In fact, React is the most used web framework in the world, with 40.34% of developers using it.

Pros of ReactJS

  • The fast rendering speed of React is one of its major advantages. Whether you are developing a simple website or making an elaborate application, the loading speed will be good. Your users won’t have to wait for its content to load.
  • Even though there are multiple JavaScript libraries, React is probably the most or at least one of the most flexible among them.
  • React’s code is uncluttered, clean, and to the point. You might take a little while to grasp all its components fully. However, it’s one of the most accessible JavaScript libraries for frontend developers who are just starting out.
  • Two-way data binding removes the extra complexity in components. The default setting keeps everything in sync. Therefore, the components remain simple, and debugging becomes easier.

NodeJS

The JavaScript runtime environment is beneficial for creating network applications quickly. The Node platform comprises an event-driven architecture with non-blocking I/O. It minimizes overhead, and a built-in HTTP server framework helps host web applications.

NodeJS is quite similar to Python’s Twisted or Ruby’s Eventmachine. All three of them are considered scalable networking engines. PayPal, Trello, and eBay leverage NodeJS for its incredible benefits.

Pros of NodeJS

  • One significant benefit of NodeJS is that the cross-platform can be deployed on any system from PC to Mac to Linux. Even a mobile device with adequate processing power is enough.
  • Companies wish to launch an application to users as soon as possible. The development time in NodeJS is a big advantage. JavaScript tackles concurrency by itself. Therefore, the compilation step isn’t necessary here. It enables developers to iterate the application extremely fast.
  • NodeJS comes with a robust online documentation. Developers find multiple resources about the strengths and weaknesses of NodeJS online. Therefore, it becomes easier to decide whether they should opt for it in their next project.
  • It has an asynchronous event loop structure. As a result, it can run non-blocking I/O code. Therefore, developers come across high scalability with low overhead costs.
  • NodeJS utilizes a single-threaded event loop which performs most operations asynchronously. It follows a callback mechanism similar to JavaScript callbacks. The callback mechanism enables it to utilize all available CPU cores at 100% while under load to give each connection its thread.

Key Takeaway

MERN full-stack development offers a Model-view-Controller architecture which makes the development process more convenient. The no-context switching of the MERN technology is another advantage for startups. The highly compatible and strong technologies work together to handle the client and server sides of the application more efficiently. MERN stack development also guarantees easy code maintenance and bug fixing.
