graphql-code-generator with dynamic typescript typeDefs

[Manest]

My condegen.yml looks like that:

overwrite: true
schema:
  - 'src/graphql/projects/typeDefs.ts' 
generates:
  src/models/graphql.ts:
    plugins:
      - 'typescript'

I have a file containing some schemas :

   const typeDefs = /* GraphQL */ `
(...)
      extend type RootSubscription {
        update(key: String): String
      }
(...)
    `;

This use case work well. That generate the typing correctly.

Now if I have some dynamic stuff like that:

 const typeDefs = /* GraphQL */ `
(...)
      extend type RootSubscription {
        ${OPERATION_TYPE.UPDATE}(key: String): String
      }
(...)
    `;

graphql-code-generator is failling with this error :

Failed to load schema from src/graphql/projects/typeDefs.ts: 
        Syntax Error: Expected Name, found "(".
        GraphQLError: Syntax Error: Expected Name, found "(".

Any idea how to make it works?

Thanks

This is currently not supported. GraphQL language is mainly static and it has tons of benefits. Making it dynamic makes it much more complex to detect and load.
If you wish to use that anyway, use custom schema loader: https://www.graphql-code-generator.com/docs/getting-started/schema-field#custom-schema-loader
