So far, 2020 has been a slow year for me in general because of the current situation of the world. But if we look at the tech world, 2020 seems the forecast is not at its end. As we are in a quick-moving industry, it is indeed good to be aware of technologies we should use for future implementations. In the 21st century, web and mobile-based applications are using and developing rapidly to overcome numerous human requirements.

到目前为止，由于当前的世界形势，总体而言，2020年对我来说是缓慢的一年。 但是，如果我们看一下科技界，2020年的预测似乎还没有结束。 由于我们处在快速发展的行业中，因此了解将来应使用的技术确实是一件好事。 在21世纪，基于Web和移动的应用程序正在使用和快速发展，以克服众多人类需求。

According to a survey, I have found that using frameworks for development purposes plays a huge role in the IT industry. Knowing and working with frameworks is one of the main job factors of the modern IT industry.

根据一项调查，我发现将框架用于开发目的在IT行业中发挥着巨大作用。 了解和使用框架是现代IT行业的主要工作因素之一。

If you observe the following states, you can see that the main job factor of the IT industry is knowing languages, frameworks, and other technologies.

如果观察以下状态，则可以看到IT行业的主要工作因素是了解语言，框架和其他技术。

As developers, we all are familiar with at least one backend framework. In this article, I am am going to discuss the three most trending backend frameworks which you should use for 2021.

作为开发人员，我们都至少熟悉一个后端框架。 在本文中，我将讨论2021年应该使用的三个最流行的后端框架。

So, get ready!

所以，准备好！

调查和统计 (Surveys and Stats)

GitHub统计 (GitHub stats)

A GitHub survey shows the number of active repositories, total pushes, count of pushes for a single repository, new forks per repository, opened issues per repository, and new watches per repository for each language. As we can see, JavaScript is at the top, as always.

GitHub的调查显示了活动存储库的数量，推送总数，单个存储库的推送次数，每个存储库的新派生，每个存储库的未解决问题以及每种语言的每个存储库的新监视。 如我们所见，JavaScript一如既往地位于顶部。

StackOverflow调查 (StackOverflow survey)

According to the StackOverflow survey, we can observe that Express is at the top as the most-loved backend framework follows by Spring and Django. As the most promising scripting language, NodeJS-based Express is at its top, while one of the most powerful languages, Python, also climbs up the ladder.

根据StackOverflow调查，我们可以发现Express是最受关注的，因为Spring和Django紧随其后是最受欢迎的后端框架。 作为最有前途的脚本语言，基于NodeJS的Express是最重要的，而功能最强大的语言之一Python也在不断攀升。

GitHub储存库 (GitHub Repositories)

As per the stats of GitHub repositories, we can see that, as a framework, NodeJS has the most number of stars. But, the gap between stars is not differentiated much as the number of forks. Spring Boot and Django have the highest number of forks, while NodeJS is having a significantly low amount of forks.

根据GitHub存储库的统计信息，我们可以看到，作为一个框架，NodeJS具有最多的星星。 但是，恒星之间的差距不会像叉子的数量那样大。 Spring Boot和Django的派生数量最多，而NodeJS的派生数量非常少。

为什么要选择Node.JS？ (Why You Should Choose Node.JS?)

Node.JS has become an all-purpose full-stack development environment. It’s based on Chrome v8, an engine for chromium browsers. Node.JS allows your programs written in JavaScript to be executed on the server. There are many frameworks built for Node, including popular ones like Express JS.

Node.JS已成为通用的全栈开发环境。 它基于Chrome v8(Chrome浏览器的引擎)。 Node.JS允许您用JavaScript编写的程序在服务器上执行。 有许多为Node构建的框架，包括诸如Express JS之类的流行框架。

NodeJS的优点 (Pros of NodeJS)

• Node.JS has opened the doors to JavaScript full-stack development, inheriting the merits of JavaScript programming as well as allowing engineers to use its libraries and features.

By looking at the above pros and the giants in the IT industry which uses Node, we can see that there is nothing to wonder why nodeJS is so popular. According to the pay scale, the salary for a NodeJS developer varies been $40,000-$130,000. So why not choose nodeJS?

通过查看以上使用Node的专家和IT行业的巨头，我们可以发现，毫无疑问NodeJS为什么如此受欢迎。 根据薪资表，NodeJS开发人员的薪水在$ 40,000- $ 130,000之间。 那么，为什么不选择nodeJS呢？

为什么要使用Spring Boot？ (Why Should You Use Spring Boot?)

Spring Boot is also a java-based open-source backend framework which used to build microservices. It is also knowing as a framework which bootstraps a spring application. In another hand, it is a tool to create standalone spring applications. If you are willing to move in to spring in 2021, first check out why you should choose Spring Boot.

Spring Boot还是一个基于Java的开源后端框架，用于构建微服务。 它也被称为引导Spring应用程序的框架。 另一方面，它是用于创建独立spring应用程序的工具。 如果您愿意在2021年进入Spring，请首先查看为什么选择Spring Boot。

Spring Boot的优点 (Pros of Spring Boot)

• Can create standalone spring applications with minimal effort, development process, and configurations. We can simply start those applications using the java-jar command.

  可以以最少的工作量，开发过程和配置来创建独立的spring应用程序。 我们可以简单地使用java-jar命令启动这些应用程序。

To be honest, I am not a person who is in love with Java. So, at a point, I will not use spring-boot as my backend framework for 2021. But, as per the stats, there are a lot of people who use spring-boot. According to the pay scale, the average salary for a spring-boot developer is varying between $50,000 and $104,000 manually, which is a little bit lower than a nodeJS developer.

老实说，我不是一个爱Java的人。 因此，在某种程度上，我不会将spring-boot用作2021年的后端框架。但是，根据统计数据，有很多人在使用spring-boot。 根据薪资表，Sprint Boot子开发人员的平均工资在50,000美元到104,000美元之间，这比nodeJS开发人员要低一些。

为什么要选择Django？ (Why You Should Choose Django?)

Django is an open-source backend development framework built with Python. As we know, Python is one of the most loved programming languages in the whole universe. It is the main reason that Django will become one of the most popular backend frameworks. Other than that, there are many reasons that you should choose Django as your backend framework for 2020.

Django是使用Python构建的开源后端开发框架。 众所周知，Python是整个宇宙中最受欢迎的编程语言之一。 这是Django成为最受欢迎的后端框架之一的主要原因。 除此之外，还有很多原因应该选择Django作为2020年的后端框架。

Django的优点 (Pros of Django)

• Django allows us to easily create dynamic web apps using Python. It’s written in Python, which is the most important advantage of Django.
  Django使我们能够使用Python轻松创建动态Web应用程序。 它是用Python编写的，这是Django最重要的优点。
• It supports MVC programming methods. So, developers are able to keep the UI layer and business logic layer separately in Django applications.

  它速度很快，但不会肿。 这意味着缩短网站的建立时间是一项很棒的工作。 您可以快速开发应用程序，而不会膨胀框架。
• Django is not a thin microservice framework. It is very powerful and versatile and it does have idiosyncrasies.
  Django不是一个瘦的微服务框架。 它非常强大且用途广泛，并且确实具有特质。
• It takes security seriously and provides tools to help you to do the same thing as developers. I’m sure we all are aware of the growing trend of cybersecurity breaches in these days. So, security is crucial and Django provides a user authentication system and tools of rank SQL injections, cross-site scriptings, cross-site request forgery, clip jacking, etc.
  它非常重视安全性，并提供工具来帮助您完成与开发人员相同的任务。 我敢肯定，我们所有人都已经意识到当今网络安全漏洞的增长趋势。 因此，安全性至关重要，并且Django提供了用户身份验证系统和工具，用于进行SQL等级注入，跨站点脚本编写，跨站点请求伪造，剪辑添加等等。

Since Django is based on Python, there is no doubt about the speed of the framework and the support for it. Also, by looking at the companies which using Django, we can see that Django has become a promising framework up to 2020. So be it with 2021 as well. If we look at the average salary for a Django developer, it varies between $90,000 to $120,000 manually. From the numbers, we can see that the demand for a Django developer is quite high.

由于Django基于Python，因此毫无疑问该框架的速度及其支持。 此外，通过查看使用Django的公司，我们可以看到Django到2020年已成为一个很有前途的框架。2021年也是如此。 如果我们看一下Django开发人员的平均工资，手动的工资在$ 90,000到$ 120,000之间。 从数字可以看出，对Django开发人员的需求很高。

结论 (Conclusion)

As we can see, NodeJS and Django have done significantly well at the end of the story even though spring-boot got some extra numbers. By considering all the availability of the resources and the community, I think NodeJS is at its peak for 2021 as well. Even though Django is a great blackened framework to be used for 2021, still NodeJS at its top because there is a solid platform for NodeJS as a runtime environment and a huge community.

正如我们所看到的，尽管spring-boot有一些额外的数字，但在故事的结尾，NodeJS和Django的表现非常出色。 考虑到所有资源和社区的可用性，我认为NodeJS也在2021年达到顶峰。 尽管Django是要在2021年使用的出色的黑色框架，但仍将NodeJS放在首位，因为它有一个可靠的平台将NodeJS作为运行时环境和庞大的社区。
