Made With Reflect4 Proxy High Quality [WORKING]

Before diving into code, we define the metrics:

Reflect4 was built from the ground up to satisfy these requirements. It uses lightweight code generation (IL emitting) and caching strategies to ensure that proxy creation cost is amortized over the lifetime of the application.

Modern anti-bot systems (Cloudflare, Datadome, PerimeterX) use TLS fingerprinting. A proxy made with reflect4 high quality rotates not just the IP, but the underlying JA3 fingerprint—making detection nearly impossible. made with reflect4 proxy high quality

| Pitfall | Solution | |---------|----------| | Forgetting to call Proceed() | Always call Proceed() unless intentionally short-circuiting. | | Modifying arguments without effect | Assign back to invocation.Arguments[index]. | | Async void methods | Avoid – Reflect4 can't easily intercept them. Use Task instead. | | Circular interceptor dependencies | Use ProxyBuilder per service, not global interceptors. |

A high-quality proxy must:

Here’s a complete, production-ready template:

// high-quality-proxy.ts
export function createHighQualityProxy<T extends object>(target: T): T 
  const handler: ProxyHandler<T> = 
    // 1. Property access
    get(target, prop, receiver) 
      console.log(`[GET] $String(prop)`);
      const value = Reflect.get(target, prop, receiver);
      // Optional: auto-bind methods to the proxy
      if (typeof value === 'function') 
        return value.bind(receiver);
return value;
    ,
// 2. Property assignment
set(target, prop, value, receiver) 
  console.log(`[SET] $String(prop) = $value`);
  return Reflect.set(target, prop, value, receiver);
,
// 3. Property existence check
has(target, prop) 
  console.log(`[HAS] $String(prop)`);
  return Reflect.has(target, prop);
,
// 4. Property deletion
deleteProperty(target, prop) 
  console.log(`[DELETE] $String(prop)`);
  return Reflect.deleteProperty(target, prop);
,
// 5. Enumerate keys (for..in, Object.keys)
ownKeys(target) 
  console.log('[OWN_KEYS]');
  return Reflect.ownKeys(target);
,
// 6. Property descriptor
getOwnPropertyDescriptor(target, prop) 
  return Reflect.getOwnPropertyDescriptor(target, prop);
,
// 7. Define new property
defineProperty(target, prop, descriptor) 
  return Reflect.defineProperty(target, prop, descriptor);
,
// 8. Prevent extensions
preventExtensions(target) 
  return Reflect.preventExtensions(target);
,
// 9. Is extensible
isExtensible(target) 
  return Reflect.isExtensible(target);
,
// 10. Get prototype
getPrototypeOf(target) 
  return Reflect.getPrototypeOf(target);
,
// 11. Set prototype
setPrototypeOf(target, proto) 
  return Reflect.setPrototypeOf(target, proto);
,
// 12. Function apply (if target is callable)
apply(target, thisArg, argArray) 
  console.log('[APPLY]');
  return Reflect.apply(target, thisArg, argArray);
,
// 13. Constructor (if target is constructable)
construct(target, argArray, newTarget) 
  console.log('[CONSTRUCT]');
  return Reflect.construct(target, argArray, newTarget);

return new Proxy(target, handler);
