{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"feat(http): simple, dynamic retrying of failed requests","articleBody":"In both Dart and JavaScript, there should be a common way to perform simple retries of failed requests, and a way to provide logic to determine whether or not a request should be retried. Functionality should be on top of `retry` and `retryWhen` methods of RxJS for the JavaScript side. For Dart, I think a wrapper would have to be created to create new streams when previous streams error.\n\nThe API may look something like this\n\n``` js\nvar req = new Request({url: 'https://foo'});\n//Simple retry\n//Will try request up to three times before giving up and propagating error/completing.\nhttp.try(req, 3).subscribe(res =\u003e this.data = res.json());\n//Dynamic retry. \n//Will try up to 3 times as long as status is 500\nhttp.tryWhen(req, 3, res =\u003e res.status === 500).subscribe(res =\u003e this.data = res.json());\n```\n","author":{"url":"https://github.com/jeffbcross","@type":"Person","name":"jeffbcross"},"datePublished":"2015-07-01T04:08:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/2810/angular/issues/2810"}
