The purpose of this article is not to suggest the best frameworks or libraries. Rather, I will examine the past, present and future of these so that you can make effective decisions for your future projects. After all, most of these are likely to be among us for the next couple of years.
| Front-end frameworks in 2021
Front-end programming has undergone a major evolution over the past few years. The rise of single-page applications and web development has created many jobs, and the future seems brighter than ever for front-end developers.
This article gives an overview of the most popular front-end frameworks in 2021.
When a frontend project uses an external package, it usually comes as a framework or library. However, frameworks and libraries are different concepts. Both contain reusable functions, methods, and classes, and are used to simplify development. The main difference is in the flow and architecture of the application.
External frameworks control the flow and architecture of the application. They define the framework for the project and allow you to insert custom code in specific areas. You cannot choose when to use a framework because it is implicitly present in your project.
External libraries, on the other hand, have no control over the flow or architecture of your project. As a developer, you are responsible for initializing them and calling the functions or methods you are interested in.
Reactive is based on components that can be reused in a project. A React application maintains a common state for its internal data and reacts to user input and events throughout its lifecycle.
The React library comes with a set of hooks that can be used to extend React's capabilities throughout the lifecycle of its components. It also includes guidelines for working with forms and other common front-end issues.
The Angular framework is written in TypeScript and is based on user interface components. It takes advantage of modularity by using components within modules. Data for the entire application is stored on shared services that act as links between components in the project.
The popularity of the Angular framework seems to be declining. This is due to the learning curve that Angular has, as well as the complexity of building a very simple application.
It is defined as a versatile framework that improves maintainability and extends testing capabilities. It includes the Vue Test Utils library, which enables low-level component testing. It's also compatible with Jest, Karma, and Mocha, among other popular testing frameworks.
Vue.js is also based on user interface components that allow the installation of HTML, CSS, and JS. It relies on template syntax to inject dynamic values into the DOM.
The Vue.js framework is based on reactive programming, which means that the framework has event listeners that will update the application state when internal events occur.
The main advantage of Vue.js is that it makes it easy to adapt the framework to existing projects. You are not required to rebuild your application from scratch to start using Vue.
Express.js defines itself as a non-negotiable framework. That means it won't provide you with guidance on how to architect your application and organize your project structure.
But it doesn't take any points away from Express.js. Minimal Definition allows developers to build flexible web applications without the constraints of a closed framework. It provides an advanced API that will enhance the performance of your applications.
Next.js extends React's capabilities. Any React application can benefit from Next.js because the basic concepts are the same. Static file maintenance, browser compatibility, and easy access to environment variables are some of the key benefits of using Next.js.
