Top Open‑Source Projects for Beginners to Master Full‑Stack and Mobile Development

The author, who frequently mentors newcomers, observes that many beginners lack hands‑on project experience, so this article introduces several open‑source projects suitable for practical learning.

Jinri Toutiao Clone Project

A close replica of the Toutiao app that scrapes data from the official application.

Implemented with RxJava, Retrofit, and the MVP pattern, and utilizes various third‑party libraries.

Key functionalities already realized include data crawling, multi‑layout news lists, and video source parsing.

Technical highlights:

News data crawling and analysis using Fiddler.

Multiple item layouts managed by a custom MultipleItemRvAdapter based on BaseRecyclerViewAdapterHelper.

Video source address parsing.

Meituan Takeaway Clone Project

The front end uses Vue, Vuex, Vue‑router, and Axios; the back end is built on a Node.js framework, and MongoDB serves as the database.

Completed features are shown below.
