Frameworks are known as an integrated software development environment. They include many usefullcomponents whose main job is to help us build nice applications. The frameworks come with a number oftoolkits, compilers, debuggers, code libraries, software interfaces, etc. Working together, they are allneeded to facilitate the working process. There are a number of frameworks which you can use in 2020 and of course later too. This articleintroduces the most valuable of them to help you make your choice.

React Native

You can use React Native for developing cross-platform mobile applications (for Android, IOS and even VR).This framework is already 15 years old (from 2015) but still occupies a leading position. Similar to the webversion of React, such applications are built on a mixture of JavaScript and XML markup, known as JSX. RNhas a bridge to all this, giving access to native rendering of the API in Objective-C (iOS) or Java (Android).Thus, your application will be rendered using the mobile components of the UI. It will look and work likeany other application and gain accesses to platform features such as a phone camera or user location. Who uses React Native: Instagram, Airbnb, Facebook, Pinterest, Tesla, Walmart, UberEats, Skype, etc.

Flutter

Flutter was launched in December 2017 by Google. It is an open-source UI Framework used for developingoutstanding apps for web, mobile and desktop with a single codebase. This means that you can use oneprogramming language and one codebase to develop two different apps: for iOS and Android. Flutterincludes third-party SDK, API for 2D, animations, native Material Design widgets, and provides the ability toreuse existing Java, Swift and Objective-C code. Despite the fact that Flutter is too young, doesn't havesupport for Windows and IDE, it's really possible to create modern applications with high performance onit. It looks like the future is behind him.Who uses Flutter: Google Ads, Alibaba, Greentea, Hamilton Musical.

Ionic

Ionic was created in 2013. Now it is one of the most popular frameworks that allows to create the bestprogressive and natural applications. This possibility makes it easy to develop apps that will work on allplatforms, including the latest mobile devices. If you are interested in the commercial success of yourapplication than definitely choose Ionic.Who uses Ionic: MarketWatch, Pacifica, Sworkit, Nationwide.

PhoneGap

PhoneGap doesn't require hardware, SDKs or compilers to create mobile apps. Today it is also one of theleading cross-platform development tools with which we have possibility to create CSS3, HTML5 andJavaScript solutions. Like Ionic, PhoneGap allows to use web technology in mobile development. It is adistribution of Apache Cordova. Another plus of PG is that many provided plugins are provided. Using it wecan develop applications that are embedded web browsers and single-page HTML.Who uses PhoneGap: Localeur, Logitech Squeezebox Controller, Untappd, HealthTap.

Xamarin

Another excellent cross-platform solution, which occupies a leading position in the world market and allowsus to create applications with a single code for various platforms (iOS, Android and Windows 10). Otheradvantages of using it are direct access to the native APIs of each platform, and when creating applicationswe can use the .NET platform and the C# programming language (as well as F#), which is quite productive,but at the same time clear and easy to learn and use.Who uses Xamarin: Olo, The World Bank, Storyo. etc.
