proxy-pattern

You can intercept object property access and mutation by defining a Proxy with get and set traps, using Reflect.get and Reflect.set inside the handlers to maintain correct property operations while enforcing validation rules.

The Proxy pattern in TypeScript centralizes control over object interactions, enabling property interception, type validation, and controlled observability like logging to support debugging and audit trails before updates occur.

To log property changes and enforce type checks, create a Proxy handler with a set trap that validates incoming values, logs the mutation, and then applies the update using Reflect.set for safe and traceable execution.

Yes, you can prevent empty string assignments by defining a set trap within a JavaScript Proxy that checks the incoming value and rejects the mutation if the string is empty, ensuring object integrity.

Use object interception when you need centralized behavior for property reads and writes, such as enforcing constraints, applying formatting, generating audit trails, or implementing access control around gets and sets.

Proxy traps validate object interactions at runtime but do not provide compile-time type safety; they require defining handlers for each trap and using Reflect correctly to avoid breaking default property operations.
