retry and catch ?

[Sinewyk]

retry and catch aren't in the tables (coming from RxJs).

You can't retry a Promise, but just map strings to http requests that returns an observable that you call retry on and catch, and you have powerful error handling.

I can't find or am not experienced enough yet to do a similar stuff with most.

Help ? 😄

PRs are welcomed :) I'm out of time a.t.m. unfortunately.

MostJS has super friendly community so you can ask (in gitter) whatever question you have (even the most stupid one) and expect for a thorough answer. I know – I did ;)

retry (works):

const retry = (n, stream) =>
  stream.recoverWith(e => n === 0 ? most.throwError(e) : retry(n - 1, stream))

catch:

stream$
.recoverWith(err => {
  // handle error and return new stream
  // or do not handle error and rethrow with most.throwError(err);
})

will probably come with a PR extending the quick response.

edit: simplified catch case
