Générateur d'extraits de schéma GraphQL fictif
A mock GraphQL schema snippet generator produces example type definitions for testing, prototyping, and learning GraphQL. When you are building a resolver, mocking an API, or teaching schema design, you need realistic type definitions without writing them from scratch each time. This tool emits well-formed GraphQL types — users, posts, products, orders — complete with fields, non-null markers, relationships, and the occasional enum, following correct GraphQL syntax. Click generate and copy the snippet into a schema file, a playground, or a tutorial. It is ideal for prototyping an API, building a mock server, and learning how GraphQL types fit together. Each snippet uses valid GraphQL notation, so it parses correctly and shows the conventions — the bang for non-null, list types in brackets, and references between types. Adapt the fields to your own domain from there.

FAQ
is the generated schema valid GraphQL
Yes. Each snippet uses correct GraphQL Schema Definition Language — non-null markers, list types, enums, and references between types — so it parses correctly and demonstrates the standard conventions you would use in a real schema.
what do the symbols mean
An exclamation mark means a field is non-null, square brackets denote a list type, and ID, String, Int, Float, and Boolean are the built-in scalar types. Referencing another type, like author: User, defines a relationship between them.
can i use this directly
It is a starting point. The snippets are valid and realistic, but you will want to adapt the type and field names to your own domain. The structure and syntax save you time; tailoring the fields to your data is quick from there.
