Syntax Error: Unexpected <EOF>

[chrise86]

Intended outcome:

When running:

npx apollo client:codegen --target=typescript --globalTypesFile=./src/__generated__/globalTypes.ts

I would expect to get types generated.

Actual outcome:

yarn run v1.22.4
$ npx apollo client:codegen --target=typescript --globalTypesFile=./src/__generated__/globalTypes.ts

How to reproduce the issue:

Not able to share the repo, but it's a fresh React Native app with the dependencies listed below. I tried running using apollo@latest and apollo@2.30.2. Also tried clearing the node_modules folder and reinstalling to no avail.

apollo.config.js:

module.exports = {
  client: {
    tagName: 'gql',
    includes: ['./**/!(*.test).{ts,tsx,js,jsx}'],
    service: {
      name: 'Tracker API',
      url: 'http://localhost:5001',
    },
  },
}

Versions

"dependencies": {
  "@apollo/client": "^3.1.4",

  "prettier": "^2.1.1",

  "typescript": "^3.8.3"
},

UPDATE: simplifying apollo.config.js to the following seems to fix:

module.exports = {
  client: {
    service: {
      name: 'Tracker API',
      url: 'http://localhost:5001',
    },
  },
}

It looks like it's the includes. Changing the line to the following fixes:

includes: ['./src/**/!(*.test).{ts,tsx,js,jsx}'],

Not sure if this is an issue or not. It happens that in my case I don't need to include anything outside of the src folder. Could it be a lack of excludes, and so it's scanning the node modules folder? This hasn't happened on previous projects.

I ran into this as well, after digging around through docs for a while the fix was actually pretty simple, I was mistakenly using the client config structure when I needed to use the server config structure.

// this one doesn't work
module.exports = {
  client: {
    service: {
      addTypeName: false,
      name: 'star-wars-api-overlay',
      localSchemaFile: './src/schemas/schema.gql',
    },
  },
};

// This one works
module.exports = {
  service: {
    addTypeName: false,
    localSchemaFile: './src/schemas/schema.gql',
  },
};
