## What it is
GraphQL Nexus is a declarative, code-first library for building strongly typed GraphQL schemas in TypeScript and JavaScript. It layers an ergonomic builder API on top of graphql-js, auto-generating SDL and TypeScript type definitions while remaining interoperable with Apollo Server and other ecosystem tools.

## Use cases
- build a type-safe GraphQL schema in TypeScript
- generate SDL and typings automatically from code
- migrate an SDL-first GraphQL schema to code-first
- define GraphQL resolvers with inline functions and full type inference
- create reusable composable field helpers to DRY up schema design
- integrate a GraphQL schema with Apollo Server or graphql-middleware

## When to choose
- you want code-first schema construction with end-to-end type safety in TypeScript
- you prefer IDE autocompletion and auto-generated type definitions over hand-written SDL
- you need interoperability with vanilla graphql-js types and existing GraphQL servers

## When to avoid
- your team strongly prefers SDL-first schema design
- you need a library with frequent releases and active development - the project has been quiet since late 2023
- you are not using TypeScript or JavaScript
