Apache Cordova

Apache Cordova is an open source project, which aims at allowing mobile developers to build the 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 for Visual Studio Tools for Apache Cordova. It works pretty well with Windows Universal, iOS and Android apps.

Building Login Page with Onsen UI Framework

Let’s see how to start building the login app in Onsen UI Framework using Visual Studio 2015.

Login Page

A login, logging in or logging on is the entering of identifying information into a system by a user in order to access that system (e.g., a computer or a website or an app).

A login generally requires the user to enter two pieces of information; i.e., first the user name and then the password. This information is entered into a login page

A user name is also referred to as an account name. A password differs from a user name, which is intended to be kept secret.

Prerequisites

Visual Studio 2015.
Visual Studio Tools for Apache Cordova.

Follow the steps, mentioned below, to build a Onsen UI with Login app, using Onsen UI Framework, using Visual Studio 2015.

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.

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 the Cordova CLI Visual Studio is used to build the project.

Step 5
