✨ PR Review
The PR introduces a comprehensive Partner Connect SDK with good TypeScript support and security features. However, there are a few critical issues that need to be addressed, particularly around required vs optional configuration and potential credential data corruption.
3 issues detected:
🐞 Bug - Required property treated as optional without providing default value, leading to undefined assignment.
Details: The constructor expects hostOrigin to be provided but the type interface marks it as optional, and no default value is set despite the documentation indicating it should default to 'https://learncard.app'. This will cause undefined to be assigned to this.hostOrigin when no value is provided.
File:packages/learn-card-partner-connect-sdk/src/index.ts (50-50)🐞 Bug - Complete property overwrite may destroy existing credential data and cause structural issues.
Details: The credentialSubject is being completely overwritten rather than updated, which could destroy existing properties from the newCredential call and may not match the expected credential structure.
File:examples/app-store-apps/1-basic-launchpad-app/src/actions/index.ts (23-23)🧹 Maintainability - Mixed module syntax can cause bundling and compatibility issues in certain environments.
Details: Using CommonJS require() for package.json in an ES module context could cause compatibility issues in some environments and bundlers.

🐞 Bug - Data Overwrite Risk: Use proper credential subject assignment that preserves existing properties: achievementCredential.credentialSubject.id = input.recipientDid; or merge objects properly.

🧹 Maintainability - Mixed Module Syntax: Use ES module import syntax with assertion: import pkg from './package.json' assert { type: 'json' }; or use createRequire for better compatibility.

✨ PR Review
The PR successfully implements a comprehensive Partner Connect SDK with clean Promise-based API and thorough documentation. The implementation includes proper security measures, type safety, and a complete example application demonstrating all SDK capabilities.
1 issues detected:
🐞 Bug - Using Node.js-specific types in browser-targeted code causes TypeScript compilation failures.
Details: The PendingRequest interface uses NodeJS.Timeout type for timeoutId, but this SDK is designed to run in browser environments where setTimeout returns a number, not a NodeJS.Timeout. This will cause TypeScript compilation errors in browser contexts.

✨ PR Review
The PR introduces a well-structured Partner Connect SDK with comprehensive TypeScript support and a functional example app. The SDK properly handles cross-origin messaging with good security practices. One previous constructor issue has been resolved with proper default values.
1 issues detected:
🐞 Bug - Passing non-string values to Error constructor results in unhelpful error messages
Details: The error handling converts an error object to string incorrectly when throwing a new Error. The actions.issueCredential call returns an error object, but passing this object directly to new Error() constructor will convert it to "[object Object]" string instead of meaningful error message.

@claude please review this PR in depth and add these docs:
This is one piece of a larger set of features enabling our app store, so you don't need to attempt to write tutorials or how-tos for this yet, that will require more holistic work, I'd just like you to focus on the more granular, scoped documentation for this branch. |
