How an Express route handler triggers a durable generator workflow with no separate worker process, no event schema, and no mount point.
A POST /orders Express route kicks off a 4-step order workflow that retries failed steps without re-running prior ones and deduplicates client retries on the order id.
How a generator workflow suspends on a latent durable promise and resumes when an HTTP handler settles it by ID.
Block a Resonate generator workflow on human approval for an indefinite duration. The workflow yields a latent durable promise; an Express gateway settles it from outside, and the suspension survives worker crashes.
How a two-step money-transfer saga is exposed over HTTP with two layers of idempotency and crash-recoverable replay.
Move funds between two accounts as a debit + credit saga, triggered by an Express POST and made durable by Resonate. Idempotency is enforced at the execution id and at the ledger row.
How a Stripe-style payment webhook becomes exactly-once when the event_id is the durable promise id and each step is a checkpoint.
Process Stripe-style payment webhooks exactly once by using the event_id as the Resonate promise id. Retries from the provider reattach to the existing durable execution instead of triggering a second charge.
A one-click checkout where the cancellation window is a durable `ctx.run` over a Promise race, not a `PENDING / CONFIRMED / CANCELLED` state row.
Start a purchase, open a 5-second window in which the user can cancel, then confirm or cancel. The window is one `ctx.run` over a Promise that races a timer against an EventEmitter signal — checkpointed, so a crash mid-window resumes from where it left off.
