Tsyringe works well for TypeGraphQL projects. What have you tried and what was not working for you?

[carlocorradini]

Yes, it's possible! \ Most IOC containers have the get function to retrieve an instance of the given class type. tsyringe instead have the resolve function. \ Therefore, you have to change the container option when building the schema to instruct type-graphql how to retrieve (get) a class instance from a class type:

import { container } from 'tsyringe';

const schema = await buildSchema({
  // ...
  container: { get: (cls) => container.resolve(cls) }
});

I can confirm this works, using tsyringe and typegraphql in a large production project :)
