Anything that users see, view, toggle, and use — the graphic interface, interaction, UX/UI, and user experience — is referred to as front-end growth. It’s also known as client-side tech, because it’s made up of keys, photographs, connections, and pages that all need to work correctly, easily, and reliably.

Front-end developers build the website’s external interface, which must be both interactive and appealing. We design and create front-end applications for web and smartphone apps with great care to make it look equally beautiful on big desktop screens and mobile devices, with frontend services that construct immersive user interfaces using cutting-edge technology.

It used to be enough for front-end developers to know a little HTML, CSS, and maybe jQuery to create immersive websites, but now they’re faced with a vast and ever-changing universe of skills to learn, software, repositories, and frameworks to master, and a relentless need to invest in personal education.

Frameworks

In 2021, a fight between Facebook’s ReactJS and the community-driven VueJS is likely. On GitHub, React currently has 159,000 stars, while Vue currently has 175,000 stars. For eg, Angular has just 67,500 stars.

This statement is supported by the quest volume in 2019 for React (blue line), Vue (red line), Angular (yellow line), and Svelte (green line), with Vue marginally ahead of React. In terms of quest length, Angular can’t keep up, and Svelte has no place in this relation.

JAMstack

JavaScript (for example, React, Vue, or VanillaJS), API (server-side processes are abstracted and accessible via HTTPS via JavaScript), and markup (templated markup that’s prebuilt at deploy time) make up the JAMstack.

It’s a technique for improving the efficiency of websites and applications by lowering scaling costs, increasing stability, and delivering a better developer experience.

IDEs (Integrated Development Environments)

In 2021, Microsoft’s VS Code will be the most common editor for most front-end engineers, just as it was in 2020.

It has almost IDE-like functionality like code completion and highlighting, and its extension marketplace allows it to be expanded almost indefinitely.

GraphQL

Although REST has long been regarded as the de facto norm for developing web APIs due to concepts such as stateless servers, RESTful APIs are increasingly being seen as inflexible when it comes to keeping up with the constantly evolving clients that access them.

Facebook created GraphQL to address the problems that developers face when working with Restful APIs.

Developers can collect data using REST APIs by fetching it from different endpoints built for a particular purpose, such as a /users/ id endpoint or a /tours/ id/location endpoint.

This would function differently if you used GraphQL. Developers will send a query with their data specifications to a GraphQL server. The server will then return a JSON object containing all of the data.

PWA

In 2021, progressive mobile applications (PWA) would undoubtedly be a reality. To provide rich mobile services to their customers, more businesses are preferring PWAs over native apps.

PWAs are dependable (instant loading, no internet connection required), simple (smooth graphics, quick responses to user interaction), and engaging (native-app feeling, great user experience).

Static Site Generators

Server-side rendering (important for SEO, but also for initial load time) and single-page applications are combined in static site generators.

Many projects already use an SSG even though they don’t need server-side rendering because tools like Next or Nuxt have useful features like markdown support, module bundlers, and optimized test runners.

Testing

While not having tests in your personal projects can seem easy, they are needed when operating in commercial and business environments. As a result, wherever possible, any developer can incorporate tests into their creation workflow.
