Apollo's official learning platform, Odyssey, offers hands-on GraphQL tutorials and trainings for developers to boost their skills. The platform has helped close to 40,000 learners over the past year, with courses now available in three new languages: Java, .NET (C#), and TypeScript, in addition to JavaScript. Learners can build a music catalog API, learn about federation, and assess their understanding through practice sections. With various channels for reaching out for help, including in-lesson comments, Discord, and the community forum, learners can share feedback and iterate on course development. The courses are currently in beta and will continue to evolve based on user experiences.
