Added documentation

[teresper-eth]

This PR adds comment documentation in src/plugins/errorPlugin.ts

The comments now explain the purpose of each import, the plugin's functionality, and the intent behind the validator compiler and error handler. This should make the code easier to understand and maintain.

Summary by CodeRabbit

• Documentation
  • Improved inline documentation for the error handling plugin, clarifying validator behavior, global error handling registration, and plugin encapsulation for reuse.
  • No functional changes; validation and error handling continue to work as before.
  • Enhances maintainability and developer understanding without affecting end-user functionality.

Walkthrough

Adds descriptive comments and documentation to src/plugins/errorPlugin.ts without altering functionality. The validator compiler override still returns data unchanged, the global error handler remains registered via handleError, and the plugin export continues to use fastify-plugin.

Poem

A nibble of notes in the plugin glade,
I twitched my ears at docs well-laid.
No logic hopped, no trails askew—
Just clearer paths for future you.
Thump-thump! I stamp, “All set to run!” 🥕
Comments bloom; the code stays fun.

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

11-17: Documentation slightly misleads about validation.

As written, the plugin uses a pass‑through validator, which disables runtime schema validation. Clarify this to avoid unsafe assumptions.

Apply this doc tweak:

- * - Sets a custom validator compiler (currently a pass-through for TypeBox schemas).
- *   This can be extended to add custom validation logic if needed.
+ * - Sets a pass-through validator compiler that returns data unchanged.
+ *   NOTE: This disables runtime schema validation. Replace with a real compiler
+ *   or remove the override to use Fastify's default Ajv if you need validation.

---

20-22: Pass-through validator disables runtime validation; reword comment or remove override.

These comments imply TypeBox handles validation, but the compiler returns data as‑is, so nothing is validated. Either (a) reword to state validation is disabled, or (b) delete the override to restore Fastify’s default Ajv.

Doc tweak:

-  // This implementation simply returns the data as-is, assuming TypeBox schemas handle validation.
-  // Modify this if you need custom validation logic.
+  // This implementation returns data unchanged and DISABLES runtime schema validation.
+  // Keep only if validation is handled elsewhere; otherwise remove this override
+  // or plug in a real validator compiler.

If you prefer a safer default, consider removing the whole setValidatorCompiler block so Fastify uses its built-in Ajv.

2-7: Imports doc is clear; confirm ESM/TS pathing.

The .js extension in ../utils/errorHandler.js is fine for NodeNext ESM, but will fail under classic TS/Node resolution. Please confirm tsconfig.json uses module/moduleResolution compatible with ESM and that build emits .js paths accordingly.

30-31: LGTM: error-handler docs are accurate and helpful.

38-39: LGTM: export comment reads well and matches usage with fastify‑plugin.
