Apache Cordova
Apache Cordova is an open source project that aims at allowing mobile developers to build applications for all the major mobile platforms, using HTML, CSS, and JavaScript technologies.
Monaca
Monaca is a software tool and service solution for building and deploying HTML5 mobile hybrid apps. It is built on top of an open source Apache Cordova. Monaca provides a full-suite of resources including Cloud IDE, local development tools, debugger, and back-end support.
Monaca's cloud-based IDE builds HTML5 hybrid mobile apps for iOS, Android, Windows, and Chrome apps, using HTML, CSS, and JavaScript.
Monaca CLI provides Onsen UI templates, device debugger, remote building, and any service which you might need directly from your terminal.
Onsen UI Framework
Onsen UI is a front-end UI framework to develop cross-platform mobile apps, using Apache Cordova and PhoneGap. It’s fully independent of frameworks and you can easily plug these components into any project, regardless of JavaScript framework.
Onsen UI templates can be used with Visual Studio 2015. All the templates are compatible with Visual Studio Tools for Apache Cordova. It works pretty well with UWP, iOS, and Android apps.
Building Range Slider with Onsen UI Framework
The <ons-range> element is used to display a Range Slider. For setting the maximum and minimum value, we use "min" and "max" attributes. The "step" attribute is used to change the value in every step.
It can be disabled using the "disabled" attribute.
Let’s see how to start building the app using Range Slider in Onsen UI Framework and Visual Studio 2015.
Prerequisites
- Visual Studio 2015.
- Visual Studio Tools for Apache Cordova.
Follow the steps, mentioned below, to build an Onsen UI with Range Slider, using Onsen UI Framework.
Step 1 Create an Onsen UI App
Let’s be ready to create a new project. Open Visual Studio 2015 and click File -> New -> Project option for New Apache Cordova app, using Onsen UI Framework.

This table gives the basic idea of how we might use each one.
| File | Why is it in your project? |
| Merge Folder | It contains the package for Android, iOS, and Windows apps. |
| www | This file contains the images, library, and JS files. |
| config.xml | Contains the settings of our app. |
| taco.json | Defines which version of Cordova CLI Visual Studio is used to build the project. |
Step 5 Adding the Range Slider Control
Go to index.html in the Solution Bar and add HTML coding. We can add our own HTML code in between <body> tags.
