About this course
This course develops practical capability in TypeScript. Its course-specific content covers Type foundations, Structured models, Reusable typing, Project configuration, followed by an applied project focused on build a type-safe api client and validation layer. 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 TypeScript or plan to take on responsibilities in this area.
Before you start
Basic computer literacy and a foundational understanding of programming languages. Prior experience with the named product helps with the practical exercises.
Build a type-safe API client and validation layer
Deliver build a type-safe api client and validation layer. 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.
