Server-Side GraphQL Authentication and Resolvers in Next.js

Securing modern web applications requires a solid understanding of how user identity is verified on the server. If you want to build robust APIs, mastering server-side authentication within a unified Next.js and GraphQL environment is an essential skill. This text-based course guides you through the core concepts of server-side authentication, helping you transition from basic API routes to secure, production-ready GraphQL resolvers. You will understand how to manage user state, protect sensitive data, and implement secure user queries. What you will learn: First, understand the foundational concepts of GraphQL schemas, resolvers, and context-based authentication. Second, configure server-side authentication utilities to securely parse and validate user sessions. Third, build a secure 'me' query resolver to retrieve authenticated user profiles. Fourth, implement type-safe resolver patterns to prevent runtime errors and security leaks. Fifth, apply best practices for managing server-side cookies and authentication headers in Next.js. The course starts with essential definitions and architectural basics before moving into step-by-step written explanations and code snippets for writing utility functions and resolvers. You will practice through structured written exercises designed to reinforce secure coding habits. This course is designed for web developers familiar with JavaScript and basic React who want to learn server-side GraphQL architecture. No prior experience with authentication protocols is required.
