Why has Vue.js become so popular?

The JavaScript ecosystem is full of choices, with many good web development frameworks and libraries to choose from. One of these frameworks is Vue.js, which is gaining a lot of popularity these days. In this post, we’ll explore why you should use Vue.js, and what makes it an attractive option for your next web project.

What is Vue.js?

Vue.js is a JavaScript framework for building web interfaces. Vue has been gaining a lot of popularity recently. It ranks number one among the 5 web development tools that will matter in 2018. If you take a look at its GitHub page you can see just how popular it has become – the community has grown at an impressive rate.

As a modern web framework, Vue ticks a lot of boxes. It uses a virtual DOM for better performance. A virtual DOM is an abstraction of the real DOM; this means it is lightweight and faster to work with. Vue is also reactive and declarative. This is useful because declarative rendering allows you to create visual elements that update automatically based on the state/data changes.

One of the most exciting things about Vue is that it supports the component-based approach of building web applications. Its single file components, which are independent and loosely coupled, allow better reuse and faster development. It’s a tool that can significantly impact how you do things.

What are the benefits of using Vue.js?

Every modern web framework has strong benefits – if they didn’t, no one would use them after all. But here are some of the reasons why Vue.js is a good web framework that can help you tackle many of today’s development challenges.

• Good documentation. One of the things that are important when starting with a new framework is its documentation. Vue.js documentation is very well maintained; it includes a simple but comprehensive guide and well-documented APIs.
• Learning curve. Another thing to look for when picking a new framework is the learning curve involved. Compared to many other frameworks, Vue's concepts and APIs are much simpler and easier to understand. Also, it is built on top of classic web technologies like JavaScript, HTML, and CSS. This results in a much gentler learning curve. Unlike other frameworks which require further knowledge of different technologies - Angular requires TypeScript for example, and React uses JSX, with Vue we can build a sophisticated app by using HTML-based templates, plain JavaScript, and CSS.
• Less opinionated, more flexible. Vue is also pretty flexible compared to other popular web frameworks. The core library focuses on the ‘view’ part, using a modular approach that allows you to pick your own solution for other issues. While we can use other libraries for things like state management and routing, Vue offers officially supported companion libraries, which are kept up to date with the core library. This includes Vuex, which is an Elm, Flux, and Redux inspired state management solution, and vue-router, Vue's official routing library, which is powerful and incredibly easy to use with Vue.js. But because Vue is so flexible if you wanted to use Redux instead of Vuex, you can do just that. Vue even supports JSX and TypeScript. And if you like taking a CSS-in-JS approach, many other popular libraries also support Vue.

• Performance. One of the main reasons many teams are using Vue is because of its performance. Vue is small and even with minimal optimization effort performs better than many other frameworks. This is largely due to its lightweight virtual DOM implementation. Check out the JavaScript frameworks performance benchmark for a useful performance comparison.
• Tools. Along with a number of companion libraries, Vue also offers really good tools that offer a great development experience. Vue-CLI is Vue’s command line tool. Simple yet powerful, it provides different templates, allows project customization and makes starting a new Vue project incredibly easy. Vue also provides its own dev tools for Chrome (vue-devtools), which allows you to inspect the component tree and Vuex state, view events and even time travel. This makes the debugging process pretty easy. Vue also supports hot reload. Hot reload is great because instead of needing to reload a whole page, it allows you to simply reload only the updated component while maintaining the app's current state.
• Community. No framework can succeed without community support and, as we’ve seen already, Vue has a very active and constantly growing community. The framework is already adopted by many big companies, and its growth is only going to continue.

While it is a great option for web development, Vue is also collaborating with Weex, a platform for building cross-platform mobile apps. Weex is backed by the Alibaba group, which is one of the largest e-commerce businesses in the world. Although Weex is not as mature as other app frameworks like React native, it does allow you to build a UI with Vue, which can be rendered natively on iOS and Android.

Vue.js offers plenty of benefits. It performs well and is very easy to learn. However, it is, of course important to pick the right tool for the job, and one framework may work better than the other based on the project requirements and personal preferences. With this in mind, it’s worth comparing Vue.js with other frameworks.
