I'm looking at porting some (Node) fp-ts code to Effect, and it's great to see

HttpClient

HttpClient

is similar to how I'd be doing it. I see it uses

globalThis.fetch

globalThis.fetch

, is it possible to pass in my own

fetch

fetch

make-fetch-happen

make-fetch-happen

in production (for HTTP caching) and

fetch-mock

fetch-mock

in tests. I also used it to adding things like HTTP request/response logging, timeouts etc (https://github.com/PREreview/prereview.org/blob/aa23343f3360327a04abc524849b499f6f4a6a70/src/fetch.ts); there might be more Effect-native ways of achieveing these though.
