@obsunified/pprof-decoder

Minimal pprof decoder + encoder. Runs in browsers and Cloudflare Workers (uses the platform DecompressionStream/CompressionStream APIs — no Node-native dependencies, no Emscripten).

import { decodeProfile, encodeProfile } from "@obsunified/pprof-decoder";

const profile = await decodeProfile(gzippedBuffer);
profile.sample.forEach((s) => console.log(s.value, s.locationId));

const reEncoded = await encodeProfile(profile);

Used by the collector's /v1/profiles ingest and by the dashboard's flame-graph renderer. Designed to do decode + minor re-encode, not full profile manipulation — for that, use Google's pprof toolchain.
