Walkthrough

This pull request updates the package version for @eggjs/mock in package.json to a beta release and refines TypeScript type management in the application extension file. The changes include switching to type-only imports, renaming a conflicting type alias, and extending the MockContext interface to incorporate two distinct context types.

Changes

File	Summary
package.json	Updated the @eggjs/mock version from 6.0.6 to 6.0.6-beta.3, reflecting a beta release change.
src/app/extend/application.ts	Changed import statements to use the type keyword, renamed Context to EggCoreContext, added a new type import for EggContext, and updated MockContext to extend both EggContext and EggCoreContext.

Poem

In a burrow of code I delight,
Hopping through types with newfound light.
Beta versions and cleaner names set the pace,
As context and interfaces embrace in grace.
Cheers from a rabbit, coding with a smile!

10-11: LGTM! Type-only imports improve type safety.

The change to type-only imports is a good practice as it:

• Prevents type information from being included in the runtime bundle
• Clearly distinguishes between value and type imports
• Avoids naming conflicts through proper type aliasing

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.
