React Native - Fetch call cached

Manosim's answer didn't work for me, but put me on the path to a solution that did work:

fetch(url, {
  headers: {
    'Cache-Control': 'no-cache, no-store, must-revalidate',
    'Pragma': 'no-cache',
    'Expires': 0
  }
})

This nailed it.

I had a similar problem with react native (Android) and fetch using clojurescript (instead of js). Adding :cache "no-store" (not in the header) stopped the behavior (caching fetch data on Android App).

I think the code in js should be something like:

fetch(url, {'cache':'no-store'})

specs fetch cache-mode

You can set a Header to prevent the request from being cached. Example below:

return fetch(url, {
  headers: {
    'Cache-Control': 'no-cache'
  }
}).then(function (res) {
  return res.json();
}).catch(function(error) {
  console.warn('Request Failed: ', error);
});
