This GraphQL Essentials training is designed to help participants quickly learn how to design, build, and consume GraphQL APIs for modern web and mobile applications. The course covers GraphQL fundamentals, schema design, queries and mutations, resolvers, authentication basics, and performance considerations. Participants will gain hands-on experience to work confidently with GraphQL for efficient, flexible API development.

• Understand the architecture, query language capabilities, and API development features of GraphQL for modern application integration.
• Set up and configure the GraphQL environment, development tools, schemas, and project dependencies for API workflows.
• Design schemas, types, queries, mutations, and resolvers using GraphQL development approaches.
• Implement API requests, data fetching, subscriptions, and service integration workflows effectively.
• Debug, test, and optimize queries, schemas, and API performance for scalability, reliability, and maintainability.
• Build secure, flexible, and production-ready API solutions using GraphQL best practices.
