Onsen UI - Cross-platform HTML5 Mobile App Framework

Onsen UI is a library of UI components to help you create beautiful hybrid and mobile web apps for both Android and iOS using Javascript.

It is open source and designed to deliver native look and feel. Apps are made out of simple HTML tags, thus providing a gentle learning curve.

Both iOS flat and Android's Material design are included. The components are optionally auto-styled based on the platform, which makes it possible to support both iOS and Android with the same source code.

The core library is written in pure Javascript (on top of Web Components) and is framework agnostic, which means you can use it with your favorite framework and its tools. Currently, we provide some extra binding packages in order to tailor Onsen UI's API for specific frameworks:

React

Angular 2+

Vue

AngularJS 1.x

Some other frameworks are supported by community packages (i.e. not tested or implemented by the core team): Aurelia, EmberJS.

Getting started

We have several resources to help you get started creating hybrid apps with Onsen UI:

• The official docs: we provide a reference for the core library (vanilla JS or jQuery) as well as the Vue, React, Angular2 and AngularJS 1.x components.
• Components overview: a list of included CSS components in both flat and Material Design. Note that these components are just pure and performant CSS without JavaScript behavior. Some extra details (such as dragging or ripple effect) are added by Onsen UI custom elements.
• Playground: an interactive Onsen UI tutorial is also available where you can learn how to use the library and play around with the components.
• Blog: There are lots of great tutorials and guides published in our official Onsen UI blog and we are adding new content regularly.
• Support: if you are having trouble using some component the best place to get help is the Onsen UI Forum. We are also available to answer short questions on Twitter at @Onsen_UI.

Onsen UI ecosystem

Because sometimes a UI framework may not be enough to make hybrid apps easily, Onsen UI comes with a complete ecosystem of well integrated tools. Meet Monaca.

Made by the same team, Monaca Platform is a toolkit that makes hybrid mobile app development with PhoneGap / Cordova simple and easy: Onsen UI Cordova-like templates, debugging suite, push notifications, remote build, back-end solutions, encryption, version control, continuous integration and more. Furthermore, it provides multiple development environments with everything already configured and ready to go:

Cloud IDE - Command Line Interface - Localkit GUI

Example with CLI:

$ [sudo] npm -g install monaca
$ monaca create helloworld # And choose the starter template
$ monaca preview # Preview on the browser
$ monaca debug # Preview on a real device
$ monaca remote-build # Production build on the cloud

See the Onsen UI Getting Started Page for more information.

Examples with source code

There are lots of sample applications written using Onsen UI. Here are some examples with source code and tutorials to give you an idea of what kind of apps you can create.

Browser Support
