Operated by Google, Angular is widespread open-source framework companies use primarily for developing dynamic single-page web applications (SPA). Companies like PayPal, Freelancer, and LinkedIn use the framework for powering their UIs.
Since developers get to work with independent libraries, React is more flexible than Angular – and it offers comparatively better response time. All in all, the technology is an excellent pick for applications that need to deliver optimal performance under significant traffic pressure.
Vue was developed in 2014 and is currently used by giants such as Baidu, Grammarly, WizzAir, Facebook, and Buzzfeed. Vue is a great pick for building single-page applications, but it can also support more complex projects and deliver optimal performance.
Vue is surrounded by an active community of developers who are happy to share their knowledge. The framework also offers detailed documentation that flattens the learning curve for developers who are Vue newbies.
Ember was developed in 2015 and since then has taken the tech scene by storm. The undeniable strength of this framework lies in the fact that it supports two-way data binding that allows developing a reliable platform for handling complex User Interfaces. Companies like LinkedIn, Netflix, and Nordstrom use Ember to build their websites.
The open-source framework is an excellent technology for single-page applications, but also large, complex web apps. However, Ember is known for being a highly opinionated framework – it makes many assumptions about the application and requires developers to conform to these expectations.
Node can handle multiple requests asynchronously thanks to a non-blocking single-threaded event loop – that's why it works so well for distributed systems that involve numerous network requests. Used by companies like Uber, PayPal, and Walmart, Node helps developers all over the world to boost the performance of their apps while writing fewer lines of code.
Currently used by companies like Nike and Fitbit – as well as open-source platforms like Lichess – Mithril uses a sophisticated virtual DOM algorithm to minimize the number of updates and accelerate the development process and ensure high performance. It has a gentle learning curve that allows software developers to start using the framework after spending very little time learning about it.
The framework has gained considerable traction on the market because it provides a structured design process. Polymer was built to take advantage of the features present in the web platform to allow developers to build components easily. It was the first library to enable interactive building applications by composing components. Many Google services and sites use Polymer – for example, YouTube and Google Play Music. Netflix benefits from Polymer as well.
