- Those familiar with NodeJs
- Those wanting to learn GraphQL
- Those wanting to learn TypeScript
- TypeGraphQL is to GraphQL what TypeScript is to JavaScript
- You might get a bit confused, the syntax used is weird
- You should get a basic understanding of GraphQL first
- I'll do a walk-through and explain the code first
TypeGraphQL reduced boilerplate. Without it, you have to update schema, data models, resolvers & type definitions. With TypeGraphQL, you only need to update resolvers and data models.
A Decorator is a special kind of declaration that can be attached to a class declaration, method, accessor, property, or parameter. Decorators use the form @expression, where expression must evaluate to a function that will be called at runtime with information about the decorated declaration.
