The back-end has inevitably come to be seen not just as a kind of “web page provider” but as a stand-alone application of significant size, capable of performing various tasks and accepting dialogues with clients of all types: web applications (web pages to which client-side programming gives a lot of intelligence), mobile applications, desktop applications, electronic devices. All these fundamental roles now go under the name of the backend, and the developers who specialize in managing are becoming figures that are increasingly in demand by companies.
What exactly is the backend?
Understanding exactly what the backend does allows you to know what skills are needed to become a pro in the sector.
All data managed by the back end is entered into databases. In many cases, these are relational databases based on MySQL, PostgreSQL, SQL Server, etc. but in the last decade, there has been a big assertion of the so-called NoSQL, which guarantees better performance in various cases, use in clusters, programming models closer to the needs of developers. Among the most common we find MongoDB and Redis;
For a backend to be usable by its clients, it must offer interfaces through which to communicate. The most common way is to offer REST-style APIs, an approach that is easy to use and ideal for any programming language.
Anyone who wants to become a backend programmer needs to delve into each of these aspects. The best approach is to choose a programming language – perhaps after trying several languages you can find one you like – and start developing programs, gradually integrating methods of interacting with the database and defining your REST APIs.
Node.js and Server Development
Node.js is a good framework that can be used both on the back end and front end. It is a very popular backend solution among developers. This is all thanks to its benefits. Node.js allows developers to reuse multiple components, increase performance and efficiency, and use various popular frameworks such as Nest.js, Express.js, and Socket.io.
If you want to save your time many times more, then you can simply delegate your tasks and hire dedicated node js developers. Thus, the experts themselves will take care of your project.
