fix(types): add missing ServiceDB interface

[joscha]

any property of type: "$.service.db" becomes an instance of ServiceDB at runtime.

A mock implementation for testing can be:

class MapServiceDB implements ServiceDB {
  private readonly store = new Map<string, any>();

  get<T extends JSONValue>(key: string): T | undefined {
    return this.store.get(key);
  }

  set(key: string, value: JSONValue | undefined): void {
    if (typeof value === "undefined") {
      this.store.delete(key);
    } else {
      this.store.set(key, value);
    }
  }
}

WHY

So the implementation in the implementation methods can benefit from it.

Walkthrough

This pull request introduces a new interface named ServiceDB in the types/src/index.ts file. The interface outlines two methods: get, a generic function that retrieves a value of type T (extending JSONValue) for a given key, and set, which stores a JSONValue (or undefined) under a given key. This structure standardizes service database operations for retrieving and storing JSON-based data.

Poem

I’m a bunny with a codey heart so light,
Hopping through changes, both day and night.
New methods get and set lead the way,
In ServiceDB, where data can play.
With every hop, the code feels so right!
🐇🌟 Happy coding under the moonlight!

250-253: Excellent addition of the ServiceDB interface!

This interface properly defines the shape of database objects that are created at runtime from properties of type "$.service.db". The interface includes well-typed methods for getting and setting values, which will improve type safety and developer experience when working with service databases.

The generic get<T> method is particularly useful as it provides proper type inference when retrieving stored values.

🪧 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.
