Duplicate declaration "Component"

See original GitHub issue

Describe the bug When ever I run webpack it gives me Duplicate declaration "Component" in the generated-models.tsx file

To Reproduce Steps to reproduce the behavior:

Any generated-models.tsx
Run with webpack & babel typescript preset
Run the following command: gql-gen ...

Expected behavior Would be not to have generated-models.tsx: Duplicate declaration "Component"

Environment:

OS: Mac OS Sierra
Codegen: 0.15.2
Node: v8.12.0

UPDATE: I also tried ts-loader instead of babel-loader & it gave me

TS2345: Argument of type '{ new (): Document; prototype: Document; }' is not assignable to parameter of type 'DocumentNode'.
  Type '{ new (): Document; prototype: Document; }' is missing the following properties from type 'DocumentNode': kind, definitions

UPDATE: I got ts-loader to work & compile with another generate. Babel typescript preset doesn’t support namespaces so I think that’s why it doesn’t work.

@harrisrobin You can use noNamepsaces configuration and the output will work with CRA (see https://graphql-code-generator.com/docs/integrations/create-react-app)
