Understand your project
Every web project has an “underlying” program that we can think of as “the brain” of the project. Let’s say for example that you want to create a blog platform. While the frontend deals with how the blog looks, the backend deals with how the information is stored on the server and how it is prepared to be shown to the end-user.
If you want someone to handle this aspect of the project then you should be on the lookout for a backend developer.
Finally, some projects have a narrow scope and can be managed by a single engineer. In those cases, a developer who can design and run both the frontend and the backend is known as a full-stack engineer.
What to look for in a frontend engineer?
On the other hand, for single-page web applications, a frontend developer should have a good understanding of 2 of the more popular frameworks on the market: Vue.js, and Angular.js. Both are excellent choices to create smooth user experiences that give a very professional look to any webpage.
What to look for in a backend developer?
Similarly, backend developers should also be familiarized with the technology that’s going to be implemented in your project. For example, if you are working with a relational database, then they should have a pretty good understanding of MySQL, MariaDB, or whatever database technology is going to be implemented.
While not necessary, having your frontend and your backend working with the same language can speed up development and facilitate communication between your frontend and backend team.
What makes Node.js stand out among competitors like Ruby on Rails is that it’s incredibly light, fast, and scalable- It also works beautifully for apps where most of the processing is done by the client.
On the other hand, Node.js can be pretty limited in cases where there is a lot of heavy CPU usage involved. If that’s the case, then you might want to have an additional framework working side by side with Node.js. In fact, the developer should know whatever framework will be used.
