Missing Type Definition File Referenced in package.json for @confluentinc/kafka-javascript@1.6.0

[tarasvalstro]

Summary

The package.json for @confluentinc/kafka-javascript@1.6.0 references a non-existent type definition file (types/index.d.ts), causing TypeScript to fail when resolving types and namespace exports.

Details

When analyzing the package using arethetypeswrong, the tool reports a missing named exports. Upon inspection of the package:

1. The Problem: The package.json specifies "types": "types/index.d.ts", but this file does not exist in the published package.
2. Actual Structure: The type definitions are located at index.d.ts in the root directory, which exports:

   export * from './types/rdkafka';
   export * as RdKafka from './types/rdkafka';
   export * as KafkaJS from './types/kafkajs';

3. Impact: Because TypeScript cannot find the file specified in the types field, it fails to resolve:
   • The namespace exports (RdKafka and KafkaJS)
   • All type definitions from the package
   • IntelliSense and type checking for consumers

Impact

• TypeScript projects consuming this package will experience:
  • Complete failure to resolve type definitions
  • Missing IntelliSense/autocomplete support
  • TypeScript compiler errors when importing from the package
  • Inability to use namespace exports (RdKafka.* and KafkaJS.*)

Expected Behavior

The package.json types field should point to an existing type definition file that TypeScript can resolve.

Actual Behavior

The package.json points to types/index.d.ts which does not exist, causing TypeScript to fail when trying to resolve types and namespace exports.

Steps to Reproduce

1. Install @confluentinc/kafka-javascript@1.6.0:

   npm install @confluentinc/kafka-javascript@1.6.0

2. Extract and inspect the package:

   npm pack @confluentinc/kafka-javascript@1.6.0
   tar -xzf confluentinc-kafka-javascript-1.6.0.tgz
   ls package/types/index.d.ts  # This file does not exist

3. Check package.json:

   {
     "types": "types/index.d.ts"  // Points to non-existent file
   }

4. Analyze using arethetypeswrong
5. Observe the missing namespace/type resolution error

Environment

• Package: @confluentinc/kafka-javascript@1.6.0
• Analysis Tool: arethetypeswrong.github.io

Additional Context

The root index.d.ts file exists and contains the proper type exports, including namespace exports using export * as. However, because the package.json types field points to a non-existent path, TypeScript cannot resolve these exports.
