Custom effects

Is it possible/recommended to create custom effects?

My team was throwing around the idea, and on looking at the existing effects in src/internal/io.js it looks like this wasn’t really intended.

What do you think?

I guess in this scenario, followLink is a more specialised form of call.

Exact. You can create an effect creator which builds the specialized call effect.

For example

// Saga to handle the effect logic
function* followLinkSaga(url) {
   yield call(fetch, url)
   //... retry logic
}

// Effect creator
function followLink(url) {
  return call(followLinkSaga, url)
}

// Use it like other effects
function* saga() {
   const {url} = yield take(ACTION)
   yield followLink(url)
}

This is excellent advice, and a very simple refactor to existing code. Will take this idea for a spin tomorrow, but please consider this issue solved 👍
