[V4] GraphQL type definitions are not generated

I’m not sure if there is another (better) way, but if you edit @strapi/plugin-graphql directly you can generate types following instructions from the Nexus docs.

The Strapi team have mentioned using patch-package as an option for making these sorts of changes permanent without having to fork the project.

In this file:
node_modules/@strapi/plugin-graphql/server/services/content-api/index.js

Add the following:

const path = require('path')

// ------ other stuff--------//

// Amend the makeSchema function (which starts on line 88) by adding shouldGenerateArtifacts & locations for generated type files.

    const nexusSchema = makeSchema({
      types: [
        // Add the auto-generated Nexus types (shadow CRUD)
        registry.definitions,
        // Add every Nexus type registered using the extension service
        types,
      ],

      plugins: [
        // Add every plugin registered using the extension service
        ...plugins,
      ],
      shouldGenerateArtifacts: process.env.NODE_ENV === 'development',
      outputs: {
        schema: path.join(__dirname, 'generated/schema.gen.graphql'),
        typegen: path.join(__dirname, 'generated/nexusTypes.gen.ts'),
      },
    });

I am not certain whether this is what you are looking for as I don’t use Apollo Studio and have been using introspection with client-side Apollo instead.
