Authentication on the Frontend

We’ve spent the last three lessons implementing authentication on our application’s backend. Now, it’s time to update the frontend code.

Fortunately, the frontend implementation will be much simpler. We’ll update the Apollo Client to send cookies with outgoing requests. Then, we’ll implement the login form, which will be very similar to what we’ve already done. Finally, we’ll look into making our authentication flow work well with React.

Sending cookies to the server

Similar to how we enabled Apollo Explorer to include cookies with outgoing requests, we need to enable cookies in the ApolloClient configuration. To do this, we need to change the configuration of the HTTP connection that ApolloClient uses. To configure the HTTP connection, we create an instance of HttpLink and configure ApolloClient to use it.
