OpenAPI Generator (https://openapi-generator.tech/) - a code generation tool covering 30+ programming languages and 30+ server-side frameworks for REST APIs, has gone mainstream with adoption by companies such as IBM, Yelp, and open-source project such as Kubernetes. Npm CLI wrapper download alone already reached 2.5 million. How can OpenAPI Generator scale from less than 10 generators to more than 130 generators with 1500+ contributors? What can we do to make it easier for open-source developers to contribute a new generator? How to engage the community to try it out and give us feedback? How to learn from mistakes in one generator and apply the lessons to the other generators? How do we test 30+ programming languages and 30+ server-side frameworks? What resources (services, tools, and more) we can leverage to help us improve the project? What to expect when testing so many programming languages and frameworks in a single project? William, the top contributor of the project, will walk you through the journey to scale the project in terms of the community, technical aspects, and test coverages so that you can apply similar techniques to your open-source and proprietary projects.
