What is back-end development, and what is the best back-end framework?


Backend programming refers to the programs or operations that are running on the server or the remote machine, so if I have to say the back-end of my website that's running on a remote server, this is responsible for handling HTTP requests, which is the web request you send when you want to get the HTML of the page, and so when I hit the server, it sends me the HTML, and then my browser actually renders the HTML, so the rendering of the HTML is happening on the front-end or the client side, but I'm actually retrieving the HTML from the page while I'm getting it from the server that's running my website.

In this article, we will learn what backend development is, what backend developers do, what the roadmap is to becoming a backend developer, and the best backend frameworks.

So What is backend development?

Back-end development is like the engine of a website or application; it's the part that you don't see but is essential for everything to work smoothly. Here is a simple explanation: imagine a website or app as a car. The front-end is like the car's dashboard and steering wheel. What you see and interact with on the back-end is like the engine under the hood. The back-end does a few key things.

  1. Data management It stores and organizes all the data needed for the website or app; this could be user information like usernames and passwords or content you see on the site like articles or pictures.
  2. Processing requests When you click a button or request something on the website, the frontend sends a message to the backend. The backend processes this request and decides what to do. For example, if you submit a login form, the backend checks if your username and password are correct.
  3.  Communication The back-end also communicates with other services like databases or external APIs, like getting weather data from a weather website. It gathers information from these sources and displays it on the front-end.
  4. Security It's responsible for making sure everything is secure. This means protecting user data and ensuring that only authorized users access certain parts of the website. In a nutshell, backend development is all about making sure the website or app functions correctly, stores and retrieves data, and keeps everything safe and secure. It's the behind-the-scenes work that makes the front-end look good and work smoothly.

Backend developer work

  • Back-end developers are located on the side of the website, which users can't see.
  • A backend developer is responsible for creating and maintaining databases.
  • A back-end developer is also responsible for monitoring security settings and preventing hacking.
  • Back-end developers work with languages like PHP, C++, Java, JavaScript, Ruby, Python, and Node.js.
  • They work with frameworks like Express, Djange Rails, Laravel Spring, etc.
  • Parts and functions developed by backend designers are made available to users indirectly through the frontend application.

Become a backend developer with a roadmap

Due to the prevalence of technology these days, many people want to code. If you are someone who wants to become a backend developer, follow this roadmap.

  1. If you are a complete beginner and learning a general programming language, I recommend Python, as it is more flexible but lacks options. Once you have a good understanding of the basics, use the framework to increase your productivity.
  2. After that, learn about the database. Web frameworks will give you a high-level understanding of databases, but understanding SQL will unlock superpowers for you. Relational databases like PostgreSQL are more popular, but no SQL database has great use cases.
  3. The next area to learn about is Linux servers and the command line. Deploying an application is not easy. Being somewhat comfortable with a server will make you a killer developer. You can then learn about cloud providers if you want to learn about cloud providers, or if you're a complete boss, you could deploy to your own servers.

The most important difference between the front and backend

The user interface is the part of a website that website users can view and interact with, such as the visual aspects of the interface, including design, navigation menu, text, images, videos, etc.

The backend is the part of the website that users cannot see and interact with, i.e., the things that are running in the background. Some popular front-end languages are HTML, CSS, and JavaScript, whereas languages like Java, C#, Ruby, and Python are employed for the backend.

Next, responsiveness of the design and performance are two main objectives of the front-end, whereas activities like writing APIs, creating libraries, and building system components without using scientific programming.

The Best Backend Frameworks

  • Django is an open-source web framework written in Python. Most famous companies like NASA, Spotify, Instagram, and Mozilla use this framework.
  • Ruby on Rails Ruby on Rails is one of the most popular and oldest back-end frameworks. Most companies, like Europe and GitHub, use these frameworks.
  • Laravel is the best choice for backend development using PSP scripting languages, so it is an open-source framework distributed by MIT.
  • Express.js is a JavaScript-based backend framework. Many companies, like IBM and Uber, are already using Express.js.
  • Flux is a microphone program written in Python. It's called the Micro Framework because it's a double-liquidated component that needs functions from the third-party library. Most popular companies, like Netflix, LinkedIn, and Young, will be using this framework.

Conclusion

The field of back-end development is a very broad one and has many solutions to many problems, not to mention good salaries and benefits. Working on designing a good back-end for your own project will improve the performance, security, and documentation of your project and make it scalable and maintainable.
