You can consider edge-mock as implementing (almost) all the types declare in the @cloudflare/workers-types typescript types package.
While edge-mock is designed to be useful when developing CloudFlare worker applications, it should be usable while developing any service-worker app including for (future) alternative edge worker implementations.
edge-mock is written in TypeScript and while you may be able to use it from vanilla javascript projects, you'd be better off writing your code in TypeScript!
There's also fetch_live (import with import live_fetch from 'edge-mock/live_fetch') which is an implementation of fetch which makes actual http requests using node-fetch. It is installed by default instead of stub_fetch in the dev server, see below.
Please Note: all the above types are designed for use with node while testing and are vanilla in-memory only implementations. They are not designed for production use or with large payloads.
