The Quick Start Guide provided in every chapter is an essential steps to help students get started with the course exercises, ensuring they have the necessary information to set up and run the applications smoothly. This includes detailed instructions on setting up projects, switching branches, and running the applications in an IDE. This guide ensures that students can focus on learning without getting bogged down by setup issues.
The Postman collection, attached to each chapter, is designed to help students run sample queries and mutations. By importing the provided Postman collection, students can easily test the GraphQL queries and mutations discussed in the course. This hands-on approach reinforces the learning and helps students understand the practical application of the concepts covered.
