GraphQL is a query language for APIs that provides a complete and understandable description of the data in your API and makes it easier to evolve APIs over time. GraphQL lets you ask for what you want in a single query by enabling clients to request their own unique data specifications, saves bandwidth, and reduces waterfall requests. In this course, Rasheeda Yehuza shows you how to set up a GraphQL in Laravel (PHP) using Lighthouse to query data. She also explains why GraphQL is important in the current age of API development and shows how to implement a GraphQL API on the users table and model that comes with Laravel.
