Set Context with Apollo Client
Quite often there will be times you'll want to update your Apollo Client based on the behaviour of users in your app, or authentication headers for logged-in users.
In this video we'll explore adding a custom Apollo Link that updates our request headers using the value from a custom context provider.
We want to pass a custom header with our HTTP request whereby the value is saved in context. The user can change the value at any time, so we'll need to fetch the value on the fly. We can do this with creating a "link chain".
