Divise

Divise (from the French word for split) will extract related iterator values into a discriminated map.

Examples

Iterators

const events = divise(
  [
    { type: "read", key: "blocks" },
    { type: "write", key: "blocks", value: 32 },
  ],
  "type",
);
console.log(events.read.length);

Async iterators

// Sample socket messages:
// { type: "connect" }
// { type: "message", content: "foo" }
const socketEvents = divise(iterateWebSocket(ws), "type");
for await (const event of socketEvents.message) {
  console.log(event);
}

Callbacks

divise(iterateWebSocket(ws), "type", {
  message(event) {
    console.log(event);
  },
});
