In the code where functions dwell,
Cloudflare gateways cast their spell,
URLs crafted with such care,
Through the cloud, they now will fare.
APIs whisper, APIs call,
In harmony, they rise and fall.

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.
  • @coderabbitai help me debug CodeRabbit configuration file.

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.

1-3: Document the function behavior and parameters.

The function lacks a detailed docstring explaining its purpose, parameters, and return value. This will help in better understanding and maintaining the code.

/**
 * Rebuilds the fetch URL if using Cloudflare AI Gateway.
 * 
 * @param {string} fetchUrl - The original fetch URL.
 * @return {string} - The reconstructed URL if conditions match, otherwise the original URL.
 */
export function cloudflareAIGatewayUrl(fetchUrl: string) {
  // rebuild fetchUrl, if using cloudflare ai gateway
  // document: https://developers.cloudflare.com/ai-gateway/providers/openai/
