What Will Be the Best Back End Development Framework for 2021

Node vs. Django vs. Laravel

What should I learn next? If you are a developer, this question should always be in your mind. Every day, new technologies are introduced and improvements are made to existing ones. Since we can’t learn all these technologies, it is really important to decide what should we learn next.

In this article, I’m going to discuss three back end development frameworks based on three different programming languages to give you an insight into what you should learn in 2021.

Node.js

NodeJS is a JavaScript runtime environment framework that can be used for cross-platform development purposes. Since JavaScript is one of the most popular languages in the current context, that popularity has lifted up NodeJS to be one of the most used back end frameworks as well. Apart from that, NodeJS brings many important features that attract developers.

  • NodeJS never waits until an API returns data since it’s asynchronous. NodeJS will move onto the next API request without waiting for the response of the previous one and the notification mechanism of Events of NodeJS takes the responsibility for delivering the response to the server correctly. Hence, NodeJS is known as asynchronous and event-driven.
  • Fast code execution.
  • No buffer.
  • Although NodeJS is single-threaded, high scalability enables it to handle a large number of requests.

NodeJS is used by some famous companies all around the world including eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Wikipins. Node JS is a perfect match if you’re building I/O bound applications, data streaming applications, Data Intensive Real-time Applications (DIRT), JSON APIs based applications, or single-page applications.

Advantages

  • Based on JavaScript, which is well known to everyone.
  • Easy learning curve and large community.
  • Contains an excellent package manager.
  • Library support.
  • Quick and easy handling of concurrent requests.
  • Simple and scalable.
  • Well established.

Disadvantages

  • Some developers may have difficulties working with asynchronous requests.
  • Nested callbacks.

Django

Source: https://www.djangoproject.com/

Django is an open-source, high-level web application framework written in Python. Django was introduced in 2005, and its idea of using Python for web development was a huge revolution. Django follows the model-template-view architecture and the main focus of this framework is to provide an easy method for the development of complex websites. Instagram, Mozilla, Bitbucket are some leading companies that use Django as their framework.

Advantages

  • Rapid Development. One of the main intentions of Django was to reduce the development time of an application.
  • Django helps to avoid much common security falls like SQL injection, cross-site scripting, cross-site request forgery, etc.
  • Scalability.
  • Supports a large set of libraries and helping modules.
  • You don’t have to worry much about user authentication and content administration since Django takes care of them for you.

Disadvantages

  • Many developers do not have expert knowledge in Python compared to JavaScript.
  • Although Django is scalable, there can be issues with small scale applications.
  • Monolithic framework.
  • Django can’t handle multiple requests simultaneously.

Laravel

Source: https://laravel.com/

PHP is another famous language among web developers and Laravel is based on PHP. Laravel follows model-view-control architecture and is robust and easy to understand. Laravel is known as a good starting point for young developers. It provides a large set of features, like flexible routing for easy scaling, configuration management to handle different environments, query builders and ORM to query databases, Schema Builder to maintain database definitions and schemas, lightweight templates, etc. 9GAG, MasterCard, Kmong are some famous companies that use Laravel in their products.

Advantages

  • High Security.
  • MVC Based.
  • Uses blade template engine.
  • Built-in authorization and authentication systems.
  • Supports test automation.

Disadvantages

  • Less inbuilt support when compared to Django and NodeJs since Laravel is lightweight.
  • Community support is minimized compared to other platforms.
  • Converting legacy systems to Laravel is difficult.
  • Updating from an older version to a new one may break your application.
  • Full-page reloads can be a bit heavy in mobile apps when compared to websites.

NodeJs vs Django vs Laravel

Authors Work

As you can see, all these three frameworks are very popular among developers and they tend to select the framework based on their preferred language most of the time. For example, If you’re good with JavaScript, you will surely go with NodeJS. But there are other aspects we should take into account when selecting a framework.

If you’re a novice developer, who doesn’t have knowledge about JavaScript, Python, or PHP, Django or Python will be a good option for you to start with. Since Python is very straightforward and simple in its syntax, you can easily understand it. So, I will rank Django at the top when it comes to the learning curve while Laravel and NodeJS come next.

Security is another measurement we need to address in any project and all these frameworks provide built-in features to make a developer’s life easy. Out of these three, Django claims first place here as well.

If we talk about scalability and performance Django can be recognized as the best framework in scalability aspects while NodeJS provides the best performance.

All these frameworks have large communities and good documentation to get started with and they’re well established. So don’t hesitate to select them for your projects.

Conclusion

Django, NodeJS, and Laravel are three back end development frameworks based on three different languages and they’re the leading frameworks of those languages.

In conclusion, I would say that learning any of these frameworks is a good idea. But if you learn NodeJS or Django, you can use that knowledge for various other purposes, like front end development, mobile application development, algorithms, machine learning, etc. Also, there are some other leading back end development frameworks like ASP.NET, Spring in the contest as well. Out of these three, NodeJS or Django will be the best investment in your future.
