Walkthrough

This update introduces comprehensive support for proxy configuration and handling across the mock server, data source management, and code generation layers. It adds proxy settings at both the global and per-data-source levels, updates server routes to support proxying API requests, and modifies the HTTP client and data source loading logic to utilize these proxy settings. The UI components are enhanced to allow users to configure proxy settings. Supporting code, configuration files, and generated outputs are updated to ensure consistent proxy handling, improved error management, and more flexible data fetching workflows.

Poem

In tunnels of proxy, the packets hop, Through rabbit holes, requests never stop. With handlers and configs, they bounce and they play, Bringing fresh data the low-code way. Now with a proxy, your APIs are free, Hopping through networks, as swift as can be! — 🐇✨

🪧 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.
  • 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 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 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.
