Walkthrough

A new "Mock Data Generator" feature was added to the application, introducing a dedicated mode accessible via the main UI. This feature allows users to define or select JSON schemas, generate mock data using faker.js, and view or copy the results in JSON or CSV formats. The UI includes schema presets, a schema editor, output view toggling (JSON/table), and integrated markdown documentation. Supporting CSS styles were introduced for the new components, including dark mode variants. The JavaScript logic was extended to handle schema parsing, data generation, view switching, copy functionality, and documentation rendering.

Poem

🐇
A brand new mode is here to stay,
Mock data hops in, hip hooray!
Schemas to write, and presets to choose,
Faker brings data—no way to lose!
Docs are in markdown, tables so neat,
Copy and paste, your workflow's complete.
With CSS and scripts, this toolkit’s elite!

🪧 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.
