Quickstart

The first useful Trigora program is ordinary TypeScript with a few durable operations.

import { effect, waitForEvent } from "@trigora/sdk";

export async function order(input: Order) {
  const payment = await effect("payment", () =>
    charge(input)
  );

  const approval = await waitForEvent("approved");

  return fulfill(payment, approval);
}

The point is not the syntax. It is this loop:

Start an execution of order.
The payment effect commits.
The program waits. No compute is held.
Kill the runtime.
Start it again. Recovery restores the execution at the wait — it does not charge again.
Send approved. The program continues and returns.

That is the product. If a future API cannot be taught in this loop, the API is wrong.

The intended client shape:

const run = await trigora.start(order, input);

// later, after restore
await run.send("approved", {
  reviewer: "omar",
});
