Cloudflare Workers is now available to everyone after its beta period. The service runs JavaScript using a V8-based environment and the Service Workers API.
Workers lets developers add application logic to requests at the edge, rather than sending every operation back to a conventional origin server.
Possible uses
- Adjust request routing or responses.
- Run lightweight logic near users.
- Build an application endpoint around supported APIs.
The runtime is different from a general-purpose VM or an unrestricted server process. Teams should check the available APIs, execution limits and data-service connections. Choosing edge execution also changes where code runs, so permissions and any sensitive data passed through it need deliberate handling.
