PhoneGap vs RIBs: What are the differences?
Developers describe PhoneGap as "Easilily create mobile apps using HTML, CSS, and JavaScript". PhoneGap is a web platform that exposes native mobile device apis and data to JavaScript. PhoneGap is a distribution of Apache Cordova. PhoneGap allows you to use standard web technologies such as HTML5, CSS3, and JavaScript for cross-platform development, avoiding each mobile platforms' native development language. Applications execute within wrappers targeted to each platform, and rely on standards-compliant API bindings to access each device's sensors, data, and network status. On the other hand, RIBs is detailed as "Build cross-platform apps that have similar architecture, enabling iOS and Android teams to cross-review business logic code (by Uber)". RIBs is the cross-platform architecture framework behind many mobile apps at Uber. The name RIBs is short for Router, Interactor and Builder, which are core components of this architecture. This framework is designed for mobile apps with a large number of engineers and nested states.
PhoneGap and RIBs can be primarily classified as "Cross-Platform Mobile Development" tools.
PhoneGap and RIBs are both open source tools. It seems that RIBs with 4.76K GitHub stars and 477 forks on GitHub has more adoption than PhoneGap with 4.15K GitHub stars and 974 GitHub forks.
