6 things you should learn in 2021

Framework

In 2021, we'll probably see a duel between Facebook's ReactJS and the community-driven VueJS. React currently has 159,000 stars on GitHub, while Vue has been starred even more-175,000 stars. Angular, for example, has only 67,500 stars.

So for 2021, front-end developers working with or wanting to work with JavaScript frameworks should focus on React and Vue as their primary choices. Angular is a valid option if you're working on large enterprise projects.

Static Site Generators

Static site generators combine both the power of server-side rendering (very important for SEO but also initial load time) and single-page applications.

Many projects these days choose an SSG even if they don't need server-side rendering because solutions like Next or Nuxt come with handy features, such as markdown support, module bundlers, integrated test runners, etc.

If you're serious about front-end development, you should take a close look into the following projects, and try to get some hands-on experience on them:

• Next (React-based), Nuxt (Vue-based), Gatsby (React-based), Gridsome (Vue-based)

JAM stack

The term JAMstack stands for JavaScript (running on the client-for example, React, Vue, or VanillaJS), API (server-side processes are abstracted and accessed over HTTPS via JavaScript), and markup (templated markup that's prebuilt at deploy time). There are some best practices if you want to work with the JAMstack:

• The entire project served on a CDN.
• Everything lives in Git.
• Automated builds.
• Atomic deploys.
• Instant cache invalidation.

Progressive web apps (PWA) will definitely be a thing in 2021. More and more companies are choosing PWAs over native apps to offer rich mobile experiences to their users.

PWAs are reliable (instant loading, work without internet connection), fast (smooth animations, quick responses to user interaction), and engaging (native-app feeling, great user experience).

Reasons for building a progressive web app are, for
example:

• Can be added to a user's home screen from the browser
• Work even if there isn't an internet connection
• Support web push notifications for enhanced user engagement
• Make use of Google's Lighthouse features

Code Editors/IDEs

Just like in 2020, Microsoft's VS Code will be the number one editor for most front-end engineers in 2021. It offers almost IDE-like features, like code completion and highlighting, and can be extended almost infinitely via its extension marketplace.

The marketplace, in particular, is what makes VS Code so awesome. Here are some of the best vs code extensions for you as a front-end developer:

• JavaScript (ES6) code snippets
• npm
• Prettier
• CSS Peek
• Vetur
• ESLint
• Live Sass Compiler
• Debugger for Chrome

GraphQL

One of the hottest topics right now and definitely a thing for you to learn or improve on in 2021 is GraphQL.

While REST has long been considering the de facto standard for designing web APIs by offering great concepts like stateless servers, RESTful APIs are more and more considered inflexible when it comes to keeping up with the rapidly changing clients accessing
them.

GraphQL was developed by Facebook to tackle the exact issues developers are facing when dealing with Restful APIs.
