GraphQL
ELI5 — The Vibe Check
GraphQL is like ordering food where YOU specify exactly what you want on your plate. With normal REST APIs, you get the whole combo meal even if you only wanted the fries. With GraphQL, you ask for exactly the fields you need and nothing more.
Real Talk
GraphQL is a query language for APIs and a runtime for executing those queries. Unlike REST, clients specify exactly what data they need in a single request, eliminating over-fetching and under-fetching. It uses a strongly typed schema to define available data.

query {
user(id: "1") {
name
email
posts {
title
}
}
}
When You'll Hear This
"The mobile app uses GraphQL so it only fetches what it needs." / "Add that field to the GraphQL schema."

Query Builder
A query builder lets you build database queries by chaining methods instead of writing raw SQL. It's like assembling a sentence with Lego blocks — `.
REST (Representational State Transfer)

Schema
