🚀 Thanks for opening this pull request! We appreciate your effort in improving the project. Please let us know once your pull request is ready for review.

Tip

Keep pull requests small. Large PRs will be rejected. Break complex features into smaller, incremental PRs.
Use Test Driven Development. Write failing tests before implementing functionality. Ensure tests pass.
Group code into logical blocks. Add a short comment before each block to explain its purpose.
We offer conceptual guidance. Coding is up to you. PRs must be merge-ready for human review.
Our review focuses on concept, not quality. PRs with code issues will be rejected. Use an AI agent.
Human review time is precious. Avoid review ping-pong. Inspect and test your AI-generated code.

Note

Please respond to review comments from AI agents just like you would to comments from a human reviewer. Let the reviewer resolve their own comments, unless they have reviewed and accepted your commit, or agreed with your explanation for why the feedback was incorrect.

Caution

Pull requests must be written using an AI agent with human supervision. Pull requests written entirely by a human will likely be rejected, because of lower code quality, higher review effort and the higher risk of introducing bugs. Please note that AI review comments on this pull request alone do not satisfy this requirement.

📝 Walkthrough

Walkthrough

Modified the allowMethodOverride middleware to normalize overridden HTTP methods to uppercase, preventing bypasses of rate limiting via lowercase method overrides. Added a test case verifying rate limits apply to requests using lowercase _method overrides.

Changes

Cohort / File(s)	Summary
Rate limit test coverage `spec/RateLimit.spec.js`	Added test case for method-override bypass scenario with lowercase `_method:'get'` on a `POST` request to verify rate limiting still applies.
Middleware method normalization `src/middlewares.js`	Modified `allowMethodOverride` to normalize the overridden HTTP method to uppercase via `req.body._method.toUpperCase()`, ensuring consistent method handling regardless of input case.

Check name	Status	Explanation
Title check	✅ Passed	The title accurately describes the main change: normalizing HTTP method case in the allowMethodOverride middleware, which is reflected in both the src/middlewares.js changes and the new test case.
