Next.js is a lightweight framework for static and server-rendered React applications that's been around since 2016.
Here are the advantages of Next.js that developers like the most:
- Elegant, laconic syntax.
- A vibrant community ready to provide support and a well-documented codebase.
- Easy entrance, especially for developers that have already worked with some of the JS frameworks.
Among Next.js's cons, we can outline:
- A small ecosystem and not so many projects written with Next.js.
- Constant upgrades and fixes that cause bugs and inconsistencies in functioning.
A technology stack of Netflix, Ticketmaster, GitHub, Hulu, and TikTok includes Next.js.
This framework implements a component-based architecture, which is trendy nowadays and considered as the future of web development. A component-based UI and declarative components help software engineers apply their problem-solving skills and develop readable and maintainable codebase.
Another indicative feature of React.js is virtual DOM – a virtual representation of a user interface stored in memory and synchronized with the "real" DOM with a ReactDOM library.
Other advantages of React.js include:
- Easiness of team development thanks to strict adherence to UI and workflow template.
- Open-source nature, a lively community, and compatibility with lots of developer tools.
Despite all of the benefits, React.js has some disadvantages too:
- Slowing down the team's work when launching the project because of complex documentation.
- Being forced to "reinvent the wheel" as React.js is a relatively young framework and there aren't many established practices and ready-made solutions.
- Lack of IE8 support, just like in many other JS frameworks.
Airbnb, Asana, Dropbox, Facebook, Instagram, and KISSmetrics are some of the prominent websites built with React.js.
The Monterail survey shows that 81% of developers note that one of the main benefits of Vue.js is easy integration with third-party tools and backend frameworks. Along with that, 60% of developers believe that documentation is well written and covers most of the issues that appear during development.
These aren't the only pros of Vue.js. In addition, these frameworks delight developers with:
- Focus on speed thanks to a virtual DOM and memory distribution.
- Low entry barrier which makes it perfect for implementation in startups.
Anyway, Vue.js is gaining its popularity in China. For example, Alibaba marketplace is built upon Vue.js.
Lately, we've seen some of the prominent software products migrating to Vue.js. Codeship switched from jQuery to Vue.js to improve user interface, reduce bugs and malfunctions, and improve the maintainability of a codebase.
Since its introduction in 2012 by Google, Angular.js has been in favor among top JS frameworks. Angular.js is one of JS MVC frameworks - a concept that was informally called “Model-View-Whatever”.
- Design patterns that facilitate maintainable software. Angular.js eliminates the confusion of classes and methods that are difficult to edit and even harder to test. With a structured code, it's easier to maintain the codebase and keep everything structured.
- Short learning curve. Angular.js is built on TypeScript, which in turn relies on ES6. That means that you don't have to learn the framework from scratch since most of the features are already familiar.
- Variety of ready-made developer tools. Under the hood, Angular.js has various types of asynchronous HTTP requests, easy routing configuration, FormControl for form validation rules, directives for dynamic HTML elements, and more.
- Disconnected components and NodeJS-like injection that makes it easy to replace components.
- Focus on testing. Angular.js supports unit tests and end-to-end testing with tools like Jasmine and Protractor.
There are a few challenges though you have to consider:
- Knowledge of code debugging tools like Augury to deploy applications.
- Complex testing of Angular.js applications that requires knowledge of testing tools.
YouTube, PayPal, Upwork, and Netflix are only a few products that use Angular.js for robust and content-rich user interfaces.
One of the prominent features of Ember.js is the Handlebars language that makes templates easier to read and understand and speeds up their loading. However, Handlebars's <script> tags used for updating the templates may clutter the DOM.
The active Ember.js community regularly updates the framework and makes backward compatibility easier.
Using Ember.js for small projects isn't reasonable as the codebase gets cluttered and filled with excessive code. Overall, using Ember.js for solving non-traditional tasks may lead to cumbersome and overblown projects.
A prominent example of feature-rich software using Ember.js is Discourse, LinkedIn, Digital Ocean, and Travis CI.
