Reproduction of Injecting Context with @nestjs/graphql and typegraphql-nestjs

This repository shows a working example of @Inject(CONTEXT) with @nestjs/graphql and an equivalent broken example in typegraphql-nestjs.

@nestjs/graphql

Based on https://github.com/nestjs/nest/tree/master/sample/23-graphql-code-first.

To reproduce:

cd nestjs-graphql
npm ci
npm run start

In a new shell:

curl --location '127.0.0.1:3000/graphql' \
--header 'Content-Type: application/json' \
--data '{"query":"query GetRecipes {\n  # returning request scoped recipes list from `RecipeService`\n  # which is empty for every request (`recipes: Recipe[] = []`)\n  recipes {\n    title\n    description\n  }\n}","variables":{}}'

Result: The first shell prints the headers of the request.

For the relevant code, see nestjs-graphql/src/recipes/recipes.service.ts.

typegraphql-nestjs

Based on https://github.com/MichalLytek/typegraphql-nestjs/tree/master/examples/3-request-scoped.

To reproduce:

cd typegraphql-nestjs
npm ci
npm run start

In a new shell:

curl --location '127.0.0.1:3000/graphql' \
--header 'Content-Type: application/json' \
--data '{"query":"query GetRecipes {\n  # returning request scoped recipes list from `RecipeService`\n  # which is empty for every request (`recipes: Recipe[] = []`)\n  recipes {\n    title\n    description\n  }\n}","variables":{}}'

Result: The first shell prints undefined
