Walkthrough

The recent updates primarily focus on enhancing the CORS configuration logic within the application. A new mechanism to check for the presence of a custom origin handler has been introduced. Additionally, the test environment has been expanded with new test cases to verify these changes, and related routes have been added to facilitate the testing of CORS settings.

Changes

File Path	Change Summary
app.js	Added logic to check for custom origin handler in CORS configuration.
config/config.default.js	Removed 'use strict'; and updated comments regarding CORS settings.
test/.../cors.default-config.test.js	New test to verify hasCustomOriginHandler is false for default CORS config.
test/.../cors.origin-function.test.js	New test to ensure hasCustomOriginHandler is true for custom CORS config.

Removal of 'use strict': Ensure that this change is intentional and compatible with the Node.js version and module system used in your project. This directive can affect variable scoping and error handling.

Consider enhancing error handling around URL parsing to ensure that any exceptions are managed gracefully, potentially logging them for further investigation.

test/cors.origin-function.test.js (1)

27-32: The test case correctly verifies the hasCustomOriginHandler flag. Ensure that this test covers all scenarios where the configuration might change.

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>.
  • Generate unit testing code for this file.
  • 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 generate unit testing code for this file.
  • @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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
