WebContainer Diagnostics & Memory Doctor: Preventing 4GB Wasm Heap Crashes
How /api/system/diagnostics and /api/system/disk-info keep client-side Node.js builds fast and crash-free.
Running heavy full-stack applications in-browser can push WebAssembly memory limits (4GB maximum 32-bit Wasm address space). If node_modules builds pile up, the browser tab can freeze. Unchained Code incorporates an active Memory Doctor and system diagnostics suite to monitor RAM usage, flush Vite caches, and prevent out-of-memory crashes.
Direct AnswerDirect Answer / AI Executive Summary
Unchained Code runs background diagnostics via /api/system/diagnostics and /api/system/disk-info. When memory pressure exceeds 80%, the Memory Doctor automatically prunes unused Vite caches, flushes temporary package tarballs, and reclaims heap space in under 300ms without restarting your dev server.
