The Apollo Learning Platform, Odyssey, has been launched to provide a free, hands-on learning tool for developers. The platform offers approachable lessons on various Apollo topics, including GraphQL and unified data graphs. Its mission is to empower developers to build apps faster by removing guesswork related to adopting new technologies. Currently, it features a single course, Lift-Off Part 1, covering the basics of building a GraphQL-powered web application using Apollo Client and Apollo Server. More courses are planned for release in the future, based on developer feedback and interest. Developers can access Odyssey at odyssey.apollographql.com and sign up for a free Apollo account to track progress and access additional features.
