GraphQL Training
Introduction to GraphQL
Gain a comprehensive overview of GraphQL, a query language for APIs and a runtime for executing those queries. Learn about its core principles, how it differs from REST, and why it's a powerful tool for building modern APIs.
Getting Started with GraphQL
Learn how to set up a basic GraphQL server. Understand the core concepts of GraphQL schemas, queries, and mutations, and get hands-on experience with setting up your first GraphQL API.
GraphQL Schemas and Types
Dive deep into GraphQL schemas and types. Learn how to define schemas, use built-in scalar types, and create custom object types, enums, and interfaces to structure your API's data.
Queries and Mutations in GraphQL
Explore the fundamentals of GraphQL queries and mutations. Understand how to fetch data using queries, modify data with mutations, and handle nested and complex data structures.
GraphQL Resolvers
Learn about resolvers in GraphQL, the functions that handle the fetching of data for queries and mutations. Understand how to create resolvers and manage data from various data sources, such as databases and REST APIs.
GraphQL Subscriptions
Discover how to implement real-time functionality with GraphQL subscriptions. Learn how subscriptions work, how to set them up, and how to use them to push real-time updates to clients.
Authentication and Authorization in GraphQL
Understand the best practices for implementing authentication and authorization in GraphQL. Learn how to secure your API, handle user authentication, and manage permissions at the resolver level.
Client-Side GraphQL
Explore how to use GraphQL on the client side with popular libraries such as Apollo Client and Relay. Learn how to set up these libraries, execute queries and mutations from the client, and manage local state with GraphQL.
Optimizing GraphQL Performance
Learn techniques to optimize the performance of your GraphQL server. Understand how to use batching and caching, defer and stream directives, and optimize your schema and resolvers for better performance.
GraphQL Tooling and Ecosystem
Explore the rich ecosystem of GraphQL tools and libraries. Learn about GraphiQL, Apollo Studio, GraphQL Playground, and other tools that make developing and debugging GraphQL APIs easier.
Advanced GraphQL Techniques
Discover advanced techniques in GraphQL development. Learn about schema stitching, federation, and building microservices with GraphQL to create a unified API layer across different services.
Hands-On Labs and Projects
Engage in hands-on labs and projects to apply your GraphQL knowledge. Work on real-world scenarios to develop practical skills in designing, building, and optimizing GraphQL APIs.
