Today, developers that know Angular have no issue finding a job. The average payment per hour they get is $59.22. So we could name Angular.js the best JS framework of 2020 if we didn’t promise you not to pick the winners here.
- Vast ecosystem
- All tools are available
- The code generation is high-quality
- Offers an elegant programming style
- Requires much effort to learn
- Still undergoes many changes
- There are very few relevant guides
Where Angular is useful:
- Single-page applications
- Mobile apps
- Web apps
- Chrome extensions
- Small data sites
- Company dashboards
Here is another top JS framework by a tech giant. Facebook released React six years ago, and the latest version is just a couple of months old. It is very similar to Angular, however lately, it surpasses the Google framework by almost all factors. It is more flexible, requires fewer resources, and updates don’t make it too unstable. You can combine React with other libraries, if necessary.
Of course, it became so widely-used partly because Airbnb and Twitter have it in their cores. But it would help if you remembered that Facebook manages the functionality and stability of these services. So why would this corporation use the framework someone else released.
- It is very flexible
- Creates files of small sizes
- Updates don’t impact stability much
- In most cases, devs need to know additional tools for the full coding
- The difficulty of the learning curve depends on the dev’s experience, knowledge, and background solutions
- The documentation is not optimized
Where React is useful:
- Single-page applications
- Handling the view layer of an app
- Creation of reusable UI components
- Large web applications
This framework saw the dev industry back in 2014, but for some reason, it gained popularity just now. Probably it wasn’t that famous before because of its Chinese origin. In China, many developers use it, and western devs have only begun mastering this technology.
It is effortless and creates files of small sizes. Its architecture is easy to apply, and the step-by-step implementation makes the dev process even more effortless. And the best thing is that you can mix a Vue-based app with another solution to create new products. Also, it offers implemented virtual DOM.
Vue pretty much takes the best of JS frameworks and mixes it in a single technology. But while it is way more flexible than others, it can be a drawback, too. Not every developer can feel comfortable when there is no structure or limits whatsoever. We’ve also compared Vue with other JS frameworks recently.
The average pay Vue developers can get $58.97 per hour. It is a bit lower than what React devs get, but still quite good. And the demand for Vue specialists grows in the western world.
- Small and quick ecosystem
- The structure of code is simple
- Easy to integrate with other apps
- Very flexible
- Might be too flexible for some devs
- Most of the guides are in Chinese
- The English-speaking community is small so far
- The set of tools is limited
Where Vue is useful:
- Building UI
- Single-page apps
- Improving existing apps (performance, UI, etc.)
- Complex apps
It allows devs to create apps that are lightweight yet powerful. Node.js provides both horizontal and vertical application scalabilities. Also, it offers a possibility for developers to work both on server and client apps.
Node.js devs get $59.49 per hour on average, and the demand for such specialists is high. Therefore, we can expect this framework to stay with us and remain in the top 5 during 2020.
- Easy learning curve
- Is sufficient as single software for development
- It’s full-stack
- High performance
- A vast community that offers answers to most problems
- No strict standards, devs have space for creativity
- API is unstable during updates
- An asynchronous programming model is more complicated for most devs
Where Node.js is useful:
- Data-intensive real-time apps
- Fast, scalable network apps
- Queued inputs
- Data streaming
While this framework remains rather minimal, it offers all the required tools devs need to create web and mobile apps. And when it comes specifically to Node-based web apps, Express.js guarantees rapid development. Moreover, using it, devs can set up middlewares to respond to HTTP requests and render HTML pages dynamically.
Express.js developers make just as much as other specialists – on the average $58.97 per hour. So it is a quite useful framework to learn today. And Express professionals will not lack work in the nearest future as the demand for their skills is high.
- Full control over external behavior and data access levels
- Fast and easy development
- No need to switch between languages to develop apps and configure servers
- Effortless to integrate other solutions
- Easy learning curve
- You need to understand the middleware plug-ins
- Sometimes the template code makes the process more complex
Where Express.js is useful:
- For the off-frame development
- Web and mobile apps
- Dynamic rendering of HTML pages
This is one of the oldest frameworks that will remain popular in 2020 because many devs are still used to it. Ember is excellent for developing complex apps partly because it is strictly organized. It’s easy to go the wrong way working on an extensive application – too many variables and code can create quite a mess. But Ember will prevent this from happening.
This framework allows working with large ecosystems and changes parts of it without harming the rest of the data. Ember is exceptionally stable and boots rapidly. But it is not that flexible. And it is not very easy to master. However, the big community is helpful.
Even though Ember is quite old, the demand for developers who know this framework is rather high. And the interest for it is not going away any time soon. On average, a developer who can work with Ember will get $58.97 per hour.
- High scalability
- Very productive
- Supports URL-oriented development
- The community is huge
- The documentation is structured and clear
- Not flexible
- Renders slowly
- Not suitable for small apps
- Issues with the testing process
Where Ember.js is useful:
- Large web-based apps
- Complex ecosystems
- Client-side apps
This client-side framework is tiny and rapid. It offers routing and XHR utilities out of the box and is excellent for developing SPAs. Also, it doesn’t depend on other libraries. Mithril has tons of documentation that is hand-crafted and filled with valuable examples of code. It doesn’t lock devs within strict patterns. Instead, it offers idiomatic pattern devs can follow, and tools that can aid them if needed.
The demand for Mithril devs seems to grow as 2020 comes closer. So even though it might be not as popular as other frameworks on this list, we expect it to be widely used in the next year.
- Small size
- Easy to learn
- Much documentation
- Very flexible
- Offers an intelligent auto-redrawing system
- Small only when zipped, doesn’t look so appealing when parsed and evaluated
- Not too popular so that teams might be suspicious towards it
Where Mithril is useful:
- Single Page Apps
- Complex user interfaces
- Streaming services
- Pretty much any web-based app
The interest for Redux is growing, so we can expect more devs learning it in 2020. And those who have already used it are ready to use this library again. The rising number of downloads only proves the popularity of this technology. Usually, developers use Redux along with React since they’re perfectly compatible.
It is an additional component of knowledge in app development. Therefore, Redux devs get a bit higher rates – $64.55 per hour on the average. And the demand for such specialists is rather high.
- Easy to start writing
- No need to worry about re-rendering – Redux does it
- Reliable state updates
- Perfectly compatible with React
- Isn’t a framework
- Community is still weak
- Isn’t a standalone tool
Where Redux is useful:
- The management of the state of an app
- To debug an app
- Server-side rendering
This is another library that exists since 2015. And during 2019, it gained much popularity among devs. GraphQL allows you to download the data from the server. You can determine what information do you need, and mix data from different sources way more effortless with GraphQL.
It is not very widely-used yet. However, almost everyone who tried this library is interested in working with it again. And over half of those who heard about it but never decided want to learn GraphQL.
So even though this library is not making a hot topic so far, it is getting more popular. And specialists expect buzz around it in 2020. Therefore, it is worth your attention, even though the demand for it is not high yet.
- Great for complex systems and microservices
- Fetches data with one API call
- There are no over- or under-fetching issues
- Adjusts the request to specific needs
- No need to validate the data format
- Doesn’t perform well with complex queries
- Too heavy for small apps
- Doesn’t understand files
- Difficult to master
Where GraphQL is useful:
- To get the data of a specific format
- When REST is not enough
Therefore, developers can spend less time and effort, creating an app. While, for instance, React needs you to write code for the app and for the framework itself, Svelte gives you freedom. Using this technology, you write code only for an app. Therefore, the code is shorter, and the file size is smaller.
This unique approach gives this framework all chances to become one of the most used technologies in 2020. Experts recommend devs to begin studying Svelte so that in the next year, they become pioneers in this technology.
- No need to write code for a framework
- Allows creating independent apps
- Small size file
- A completely new approach to the development
- Short learning curve
- The community is very scarce so far
- The set of features is limited
Where Svelte is useful:
- Writing framework-independent apps
- Creating basically any web or mobile app
The bottom line
It is impossible to single out a particular framework or library. Each of them has its advantages and pitfalls. But we can predict which tools will be accessible in 2020 based on trends, and this list showcases the candidates we think will be widely-used.
Of course, picking a framework or a library for a specific project is not easy. You need to understand the needs and capabilities of a particular technology. Then you can be sure your instruments will lead you to a great application.
Sure, you need quite a lot of experience and expertise in the app development to choose the correct solution for your project. That’s why we’re always ready to offer our help. We have worked and are continually working on different apps with various purposes and requirements.
