In today’s world, good knowledge of various frameworks is very important. They allow you to quickly develop both prototype and real projects. If you are working in the startup space then you are expected to whip something cool in no time and that’s where knowledge of framework excel.
It also helps you to get a better job and take your career to next level, if you are stuck somewhere working on boring jobs, like just starting and stopping the server, setting up some cron jobs, and replying to the same old emails maintaining legacy applications.
In this article, I have shared 12 useful frameworks related to Java development, mobile app development, web development, and Big Data. If you have another good framework which you think Java and web developers should learn in 2021, then feel free to share it in the comments.
1) Angular 2+
Since Google is behind Angular, you can rest assured in terms of performance and regular updates. I strongly believe AngularJS is here for the long run, hence, investing time in it is completely justified. If you decide to learn Angular in 2021, then Angular - The Complete Guide from Udemy is a good starting point.
2) Node JS
3) Spring Boot
I have been using the Spring framework for many years, so when I was first introduced to Spring Boot, I was totally surprised by the relative lack of configuration. Writing a Spring-based Java application using Spring Boot was as simple as writing a core Java application using the main() method.
Even though I have tried Spring Boot, I have yet to learn many things, and that’s why it’s on my list of things to learn in 2021.
I have also bought the Spring Boot Masterclass, one of the best online courses to learn Spring Boot, from Udemy for just $10 last month, and I look forward to using that in 2021.
The web development world is divided between Angular and React and it’s up to you what you choose. Most of the time, it’s dictated by circumstances; for example, if you are working in a React-based project, then obviously, you need to learn React.
If you decide to learn to React in 2021, then the React.js: Getting Started course from Pluralsight is a good starting point.
Bootstrap supports responsive web design, which means the layout of web pages adjusts dynamically depending upon the browser’s screen size.
In the world of mobile, BootStrap is leading the way with its mobile-first design philosophy, emphasizing a responsive design by default.
If you are a web developer and don’t know Bootstrap, 2021 is the right time to get started with it. Bootstrap 4 From Scratch is a good starting point for your Bootstrap journey in 2021.
You can do animation, send HTTP requests, reload pages, and perform client-side validation by writing just a couple of lines of code.
If you decide to learn jQuery in 2021, then I suggest you take a look at this jQuery master class, a free online course from Udemy for learning jQuery.
7) Spring Security 5
There is no substitute for security, and in 2021, it will be even more important. Since Spring Security has become synonymous with web security in the Java world, it makes perfect sense to update yourself with the latest release of Spring Security in 2021.
The new version 5.0 of Spring security includes many bug fixes and a complete new OAuth 2.0 module. Even if you don’t know Spring Security, you should consider learning it in 2021, and there is no better way than joining Eugen Paraschiv’s Learn Spring Security MasterClass.
8) Apache Hadoop
Big Data and automation are the focus of many companies in 2021, and that’s why it becomes important for programmers to learn Big Data technologies like Hadoop and Spark. Apache Hadoop is a framework that allows distributed processing of large data sets across clusters of computers using simple programming models.
It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. It’s based upon the popular Map Reduce pattern and is key for developing a reliable, scalable, and distributed software computing application.
I have already enrolled in The Ultimate Hands-On Hadoop last month, and if you decide to learn Hadoop in 2021, you can join, too, on Udemy.
9. Apache Spark
This is another Big Data framework that is gaining popularity. Apache Spark is a fast, in-memory data processing engine with elegant and expressive development APIs to allow data workers to efficiently execute streaming, machine learning, or SQL workloads that require fast iterative access to datasets.
You can use Spark for in-memory computing for ETL, machine learning, and data science workloads to Hadoop. I have already shortlisted the Apache Spark Fundamentals course from PluralSight to go through in 2021. If you are in the same boat, you can check out that course to get some inspiration
By the way, you would need a Pluralsight membership to join this course, which costs around $29 per month or $299 per year (14% discount). I highly recommend this subscription as it boosts your learning and as a programmer, you always need to learn new things. Alternatively, you can also use their 10-day-FREE-PASS to watch this course for FREE.
Apache Cordova is another mobile application development framework originally created by Nitobi. Adobe Systems purchased Nitobi in 2011, rebranded it as PhoneGap, and later released an open-source version of the software called Apache Cordova.
If you’d like to learn Cordova in 2021, then please check out Build iOS & Android Apps with Angular and Cordova, one of the exciting courses for learning Cordova.
Firebase is Google’s mobile platform that helps you quickly develop high-quality mobile apps and grow your business. You can choose Firebase as a backend for your Android or iOS application.
If you are looking to move into the lucrative business of mobile application development in 2021, then learning Firebase is a very good idea, and Advanced iOS and Firebase: Rideshare is a good place to start.
Xamarin is a way to make mobile apps quickly for all platforms with a single, shared C# code base, build a custom native user interface for each platform, or use Xamarin.Forms to write a single shared user interface across platforms.
It’s owned by Microsoft and quickly becoming popular for creating mobile apps for C, C++, and C# developers.
If you already know one of the C languages and you’re looking for a career in mobile app development, then I strongly suggest you learn Xamarin in 2021, and The Complete Xamarin Developer Course: iOS And Android! is a good course to start with.
That’s all about what to learn in 2021. These frameworks are in great demand, particularly Spring, Node.js, and AngularJS. Learning these frameworks will not only improve your chances of getting a job but also open many doors of opportunity.
Even if you are settled down in your job, keeping yourself up-to-date with the latest and greatest technologies is essential for your career growth.
So, I suggest you pick a couple of these frameworks and learn them in 2021. If you are a Java developer, then Apache Spark is a good choice, but if you are interested in a programming language rather than a framework or library, then Kotlin looks good in 2021.
P.S. — If you are not sure how to learn new technology like a programming language, framework, or a library in 2021 then please see my post about 10 ways to learn a new technology or programming language here.
