Response Size Guard

Response Size Guard in Solvix prevents processing excessively large responses from the server.

It protects your application from memory overload, crashes, and unexpected large payloads.

Why Response Size Guard?​

In production systems:

  • APIs may return unexpectedly large responses
  • Large responses can freeze UI or crash servers
  • Bandwidth and memory usage increases

Response Size Guard ensures safe response handling.

Basic usage​

const client = createClient({
  security: {
    maxResponseSize: 1024 * 1024, // 1MB
  },
});

How it works​

  1. Response is received
  2. Size is checked before parsing
  3. If size exceeds limit → request fails

Example​

await client.get("/large-data");

If response exceeds limit:

Error: Response size exceeded

Use cases​

API protection​

Prevent unexpected large payloads

Frontend safety​

Avoid UI freezes

Backend stability​

Prevent memory spikes

Error handling​

try {
  await client.get("/data");
} catch (error) {
  console.log(error.message);
}

Best practices​

  • Set limits based on API expectations
  • Use lower limits for frontend apps
  • Combine with body size guard

Integration​

Works with:

  • Body Size Guard
  • Snapshot Debugging
  • Security Layer

Summary​

Response Size Guard protects your system from large responses and ensures stable performance.
