Swagger Codegen, which is an open-source code generator for REST API, has become very popular in recent years. Many companies, from start-ups to IT conglomerates such as Cisco, IBM, VMWare, are using it in production to streamline the development process. The project covers a wide range of programming languages and server-side frameworks. How does the project grow from less than 50 contributors to 850+ contributors from all around the world with 10000+ commits in 4 years? William Cheng, the top contributor of Swagger Codegen, will share the journey the community went through and the lessons learned from building a vibrant developer community.
On May 2018, William Cheng and 40+ top contributors decided to fork Swagger Codegen to maintain a community-driven version called "OpenAPI Generator" (https://openapi-generator.tech). Please refer to the Q&A (http://bit.ly/2MS9w5h) for more information.
