This pull request focuses on improving developer ergonomics and documentation for backend API utilities, as well as making minor enhancements to project scripts. The most significant changes are a thorough documentation pass and refactoring of the apps/backend/src/lib/types.ts module to clarify its exports and usage, plus a small update to database script targets and a new module creation script in package.json.

API utility documentation and ergonomics improvements:

• Thoroughly documented and clarified all exports in apps/backend/src/lib/types.ts, including API response helpers, HTTP status codes, type-safe route handlers, and wide event logging types, making the file much easier for developers to use and understand. [1] [2] [3] [4]

Project script enhancements:

• Added a new new-module script to package.json for easier module scaffolding.
• Updated database-related scripts in package.json to target the @repo/db package instead of the backend app, improving accuracy and maintainability.

Pull request overview

This PR improves developer ergonomics by enhancing documentation and clarifying exports for backend API utility types, and it updates root-level project scripts to better target the database package and streamline module scaffolding.

Changes:

• Expanded/clarified inline documentation and export intent in apps/backend/src/lib/types.ts (API response helpers, OpenAPI helpers, and wide-event logging types).
• Updated root db:* scripts to run against @repo/db instead of the backend app.
• Added an additional root script name for module scaffolding.

• addToEvent uses Object.assign, which performs a shallow merge. For nested objects like user or error, subsequent calls will overwrite the entire nested object rather than merging fields. Consider clarifying in the docstring that merging is shallow (and callers should spread existing nested objects when extending them), or implement a deep-merge strategy if progressive nested enrichment is expected.

/**
 * Merges additional fields into the active wide event.
 *
 * Safe no-op if the wide-event middleware has not initialized
 * an event object for the request.
 *
 * @param c - Hono request context
 * @param fields - Partial event fields to merge
 */
export function addToEvent(
	c: Context<AppEnv>,
	fields: Partial<WideEvent>,
): void {
	const event = c.get("wideEvent");
	if (event) Object.assign(event, fields);
}
