About this course
This course develops practical capability in GraphQL. Its course-specific content covers Schema modelling, Resolver execution, Service controls, Testing and evolution, followed by an applied project focused on build a schema-driven graphql service. The lessons include concrete configuration, design, testing or operational decisions appropriate to the subject.
Who this is for
Administrators, developers and practitioners who work with GraphQL or plan to take on responsibilities in this area.
Before you start
Basic computer literacy and a foundational understanding of web development. Prior experience with the named product helps with the practical exercises.
Build a schema-driven GraphQL service
Deliver build a schema-driven graphql service. Use the module outcomes to state requirements, demonstrate a working result, test an expected failure or boundary case, and document assumptions and follow-up work.
Course content
