I want to develop a hybrid mobile application and I want to know what is the difference between Cordova and ionic?
PhoneGap is the base, cordova is from Apache which acquired Phonegap. They both are nearly the same now, and ionic is a framework to enhance frontend UI
ionic framework is an open source sdk tools which consists of css templates and javascript libraries mainly angularjs using its directives we write code. But whereas Apsche Cordova is a plattform which acts as an interface for our output view of an application.
I think, Cordova is an open source mobile development framework. It is used by the developers for building cross-platform mobile applications. It has a unique code base. Cordova can be developed with the help of HTML5, JavaScript, and CSS.
Ionic is a framework which is a set of CSS classes and JavaScript library. It is built on the top of Cordova with the help of AngularJS.
PhoneGap is an Adobe product. It is powered by Cordova
Here is an extract from Apache Cordova Wikipedia page, but that is true for PhoneGap and Ionic as well:
The resulting applications are said to be hybrid, meaning that they are neither truly native mobile application (because all layout rendering is done via Web views instead of the platform's native UI framework) nor purely Web-based (because they are not just Web apps, but are packaged as apps for distribution and have access to native device APIs).
All three projects are free and open-source.
