Is this course hands-on or theoretical?

Very hands-on. You’ll write mutations, set up resolvers, and deploy a functioning GraphQL server using real tools.

What if I get stuck during implementation?

You’ll have access to a learner community, discussion forums, and walkthroughs to support you throughout the course.

Will I learn authentication and access control?

Yes. You’ll implement token-based auth and control query/mutation access using user roles.

Does this course include real-time data?

Yes. Module 2 includes GraphQL subscriptions using a pub/sub model for real-time updates.

What kind of databases are covered?

You’ll connect both SQL and NoSQL databases using resolvers and data loaders.

Can I use this course to prepare for job roles?

Definitely. This course teaches production-level GraphQL practices used in industry.

Do I need to know deployment platforms beforehand?

No prior deployment experience is needed. You’ll learn step-by-step how to host your GraphQL server.

What will I get if I subscribe to this Specialization?
