Advanced Node Application Development With GraphQL Training Course


GraphQL is a data query language for APIs. GraphQL is also an execution engine for loading data from server to client. It is the much-needed alternative to the traditional REST API.

This instructor-led, live training (online or onsite) is aimed at web developers who wish to develop an advanced node application using GraphQL.

By the end of this training, participants will be able to:

  • Create mutations to enable clients to manipulate data in databases.
  • Script an automated test suite for a node application.
  • Use GraphQL schemas to define data interaction.
  • Secure node application data with an authentication system.

Format of the Course

  • Interactive lecture and discussion.
  • Lots of exercises and practice.
  • Hands-on implementation in a live-lab environment.
