About this course
This course develops practical capability in Express.js. Its course-specific content covers Express routing, API behaviour, Persistence and access, Service verification, followed by an applied project focused on build an authenticated express api. 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 Express.js 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 an authenticated Express API
Deliver build an authenticated express api. 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.
