Summary of Changes

Hello @drewwells, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a crucial modification to the HTTP request mechanism by adding a 'Referer' header. The primary purpose of this change is to resolve potential 403 Forbidden errors that can arise when making network requests, ensuring smoother and more reliable data retrieval. By providing a valid referrer, the application can bypass server-side restrictions that might otherwise block requests.

Highlights

• Referrer Header Addition: A 'Referer' header has been added to HTTP GET requests within the 'get' function in 'lib.js'.
• Error Mitigation: This change is specifically implemented to prevent 403 Forbidden errors that can occur when a referrer header is absent.

Code Review

This pull request adds a Referer header to requests made by the get function to prevent potential 403 Forbidden errors. The change is correct and directly addresses the issue. However, this change will break existing unit tests in test/cli.test.js because they were not updated to account for the new header. I have added a comment highlighting the need to update the tests to maintain the integrity of the test suite.

[gemini-code-assist]

Adding the Referer header is a good solution to avoid 403 errors. However, this change breaks the existing unit tests in test/cli.test.js. The test case 'get function should make HTTPS requests' now fails because its assertion on https.request doesn't expect the headers object. Please update the test to include an expectation for this new header to ensure the test suite passes and properly covers this new behavior.
