WebAssembly runtime

Install the versioned runtime:

npm install @sketchlog/wasm

Initialization is asynchronous and methods use camelCase:

import { StreamLog } from "@sketchlog/wasm";

await StreamLog.init();
const log = new StreamLog();
log.addLatency(42);
log.addBatch([10, 20, 30]);

const response = await fetch(
  "/v1/namespaces/frontend/streams/client-telemetry/merge",
  {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "X-SketchLog-Auth-Token": token,
    },
    body: JSON.stringify(log.serialize()),
  },
);
if (!response.ok) throw new Error(`merge failed: ${response.status}`);
log.reset();

Runtime 64-bit counter getters return bigint; serialized counters are decimal strings so JSON transport cannot round them. The authenticated merge endpoint validates the complete state, dimensions, counter sums, and compatibility before merging. Its normal request-size limit still applies.

CI builds the Emscripten output and runs the packaged Node smoke test. Browser deployments must provide the generated .wasm file through the package's locateFile mechanism when their bundler does not do so automatically.
