GraphQL Course Overview

GraphQL Course Overview

The GraphQL course offers a comprehensive learning path for developers interested in mastering GraphQL, starting from basics of JavaScript and Node.js to advanced GraphQL concepts. In Module 1, learners will refresh their understanding of JavaScript, delve into Node.js and its async programming model, and learn to integrate NoSQL databases with an Express server. Module 2 transitions into React.js, teaching learners about component communication and modern development tools like Webpack and Babel.

Module 3 focuses on React best practices, such as immutability, pure functions, and hooks for state management. Module 4 is where GraphQL takes center stage, covering design principles, schema types, and queries. Finally, Module 5 dives into mutations, subscriptions, and schema design, culminating in a full application development using Apollo client with React.

Throughout the course, hands-on exercises will solidify the knowledge gained, equipping learners with practical skills to build efficient and flexible data-driven applications. This course will help developers transition from traditional REST APIs to GraphQL, enabling them to create more powerful and maintainable APIs.
