#32 Subscribing To Booking Changes

In addition to queries and mutations, Apollo Client has excellent support for GraphQL subscriptions. Given a stream of subscription data, it’s easy to merge that data directly into the Apollo cache. We set up the client to subscribe to booking changes and update the booking calendar in near real-time whenever a booking is created or canceled.

#33 Refetching Queries

Most of the time you’ll let Apollo Client cache all the query results and not think twice about it. But sometimes you need to refresh cached query results in response to a particular user action, such as creating a booking. We’ll show you how!

#34 Infinite Scroll Pagination

Paginating query results is such a common need that Apollo Client makes it easy to do. We first modify our backend GraphQL API to support offset-based pagination. Then we tie pagination into the frontend so that getaway places can be fetched and displayed in batches.
