Solution / fetch-retry

Fetch API with retry functionality

fetch-retry

Adds retry functionality to the Fetch API by wrapping isomorphic-fetch and retrying failing requests.

npm package

npm install fetch-retry --save

Example

fetch-retry works the same way as fetch, but also accepts a retries property on the options argument. If retries is not specified, it will default to using 3 retries.

var fetch = require('fetch-retry');

fetch(url, { retries: 5 })
  .then(function(response) {
    return response.json();
  })
  .then(function(json) {
    // do something with the result
    console.log(json);
  });

Caveats

The fetch specification differs from jQuery.ajax() in mainly two ways that bear keeping in mind:

• The Promise returned from fetch() won't reject on HTTP error status even if the response is a HTTP 404 or 500. Instead, it will resolve normally, and it will only reject on network failure, or if anything prevented the request from completing.
