Cloudflare Workflows Breaking in the World of Workflows 🚀☁️ #76
Cloudflare is on a developer week run and updates!
In the previous issue, Lambda in scale of billions 🚀☁️ #75 we looked into how Lambda has gone up with adoption and invocations.
Elad Ben-Israel and the Winglang bid farewell. Winglang, which was on the journey to re-write the way applications would be built and a programming language for the Cloud has officially decided to sunset, given how the cloud space was not able to adapt to it.
Did an alternative of AWS Step Functions come to rise? Cloudflare Workflows now GA enables developers to define workflows (or State Machine) in a programmatic approach with -
import { WorkflowEntrypoint, WorkflowStep, WorkflowEvent } from 'cloudflare:workers';
And defining steps (or tasks in Step Functions world) with an async function -
await step.do('send-confirmation-email', async () => { } )
That can even work with events and wait for events to build in the loop of real-world use cases that require events and data from external triggers or updates.
