Automatic cookies

[cloud8421]

Please feel free to correct me.

I've tried to use the fetch api to login against a service which sets a cookie in case of success.

The session cookie gets correctly set and subsequent requests to the same service pass authentication without me configuring anything at the code level, which makes me assume that cookies are automatically managed by the JavascriptCore runtime.

I can't find a way to manipulate them though, is that by design?

As a side note, does this mean that I'm just better off using a different authentication flow?

Thanks for your work on this!

They're automatically managed by the Objective-C network stack, which is used internally by fetch. We haven't exposed any explicit support for them though. This would need to be implemented as a native "RCTCookieJar" module.

Thanks for the clarification, I'll keep it in mind.

How to get the cookie in client?

@iostalk I've created a basic cookie manager that allows you to get/set cookies from react native: https://github.com/joeferraro/react-native-cookies

Awesome @joeferraro

@joeferraro I'm trying to use your cookie manager, everything is in place, I require it successfully, but when I try to call any method on the object CookieManager it throws this error: Error: Cannot read property 'getAll' of undefined

This is my code:
var React = require('react-native');
var CookieManager = require('react-native-cookies');
console.log(CookieManager);
CookieManager.getAll((err, res) => { console.log('cookies!'); console.log(err); console.log(res); });
Is weird cause CookieManager is defined, since it gets logged properly in the console, with all its methods.
Any idea where I went wrong?

@xavibonell did you include the native RNCookieManagerIOS.h/m files in your Xcode project? It's not sufficient just to require the js.

[nicklockwood]

@joeferraro this is likely to be a common source of confusion. It might be a good idea to include an invariant inside your index.js to the effect of:

var invariant = require('invariant');
invariant(
   NativeModules.RNCookieManagerIOS,
   'Add RNCookieManagerIOS.h and RNCookieManagerIOS.m to your Xcode project.'
);

@joeferraro I am faced with the same issue as @xavibonell
Any clue anyone?

For anyone curious about React Native cookie handling I made an example project that shows how to use cookie authentication. It makes use of the library from @joeferraro https://github.com/ryanmcdermott/react-native-login
