📝 Walkthrough

Walkthrough

The changes introduce enhanced validation and parsing logic for publishable keys in the @clerk/shared package. The core logic in keys.ts is refactored and expanded to strictly check key formats, handle decoding errors, and validate the structure of decoded keys. New utility functions and detailed JSDoc comments are added for clarity and maintainability. The test suite is updated with new and revised test cases to cover various invalid key scenarios, including keys with extra or malformed characters. A changeset file is added to track the patch update and describe the enhancement.

Assessment against linked issues

Objective Addressed Explanation

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Explain this complex logic.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai explain this code block.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and explain its main purpose.

File: .changeset/tangy-garlics-say.md:1-2
Timestamp: 2025-06-13T16:09:53.061Z
Learning: In the Clerk JavaScript repository, contributors create intentionally empty changeset files (containing only the YAML delimiters) when a PR touches only non-published parts of the codebase (e.g., sandbox assets). This signals that no package release is required, so such changesets should not be flagged as missing content.

Timestamp: 2025-06-10T17:35:08.986Z
Learning: In the APIKeys service methods (packages/clerk-js/src/core/modules/apiKeys/index.ts), error handling is intentionally delegated to the component level rather than being implemented within the service methods themselves. This architectural pattern allows calling components to handle errors according to their specific UI needs.

7-19: Well-documented type definition!

The JSDoc comments clearly describe each option in the ParsePublishableKeyOptions type, improving code maintainability.


47-65: Robust validation logic for decoded keys!

The helper function correctly validates that decoded keys end with exactly one '$' character and contain a domain separator. This prevents malformed keys from being accepted.


108-124: Excellent error handling improvements!

The enhanced error handling with try-catch for base64 decoding and format validation provides clear error messages for different failure scenarios. This will help developers quickly identify and fix issues with publishable keys.


145-168: Clean and explicit validation logic!

The refactored function improves readability with explicit validation steps and early returns. Each check is clear and the use of the validation helper maintains consistency.


170-200: Well-documented caching implementation!

The JSDoc clearly explains the memoization pattern, and the Map-based caching provides efficient performance for repeated URL checks.


202-244: Comprehensive environment detection utilities!

The functions correctly support both legacy and new key formats with clear JSDoc documentation explaining the supported prefixes.


246-275: Well-implemented cookie suffix utilities!

The functions correctly generate URL-safe base64 hashes and create suffixed cookie names. The JSDoc clearly explains the purpose and implementation details.

53-75: Excellent edge case test coverage!

The new test cases comprehensively cover invalid key formats including extra characters, multiple $ characters, invalid domains, and decoding failures. The tests properly verify both the null return path and error throwing with the fatal option.


142-161: Thorough validation test coverage!

The test cases properly verify that isPublishableKey returns false for all invalid key formats, ensuring the refactored validation logic works correctly.
