## What it is
gqlgen is a Go library for building GraphQL servers using a schema-first approach with code generation. It generates type-safe resolvers and models from GraphQL Schema Definition Language files, avoiding untyped map[string]interface{} code.

## Use cases
- build a graphql server in go
- generate type-safe graphql resolvers from a schema
- schema-first graphql api development
- implement graphql subscriptions in golang
- avoid n+1 queries with dataloader in graphql
- generate go models from graphql schema
- create a typed graphql api backend

## When to choose
- you want a schema-first, type-safe GraphQL server in Go
- you prefer code generation over runtime reflection for GraphQL
- you need subscriptions, dataloader, or custom directives in a Go API
- you want to avoid map[string]interface{} in your GraphQL layer

## When to avoid
- you prefer writing resolvers by hand without codegen
- your project is not in Go
- you need a schema-last (code-first) GraphQL approach
- you want a runtime-only GraphQL library with minimal build steps

## Facets
- artifact type: library
