Example: Demonstrate issue with client resolvers and server edges

[jonreading81]

Description

This Example is to demonstrate an issue with client resolvers with server edges.

This example has taken the Todos example and updated Relay to the latest release and amended it to use a client resolver which points to a server edge, in this case they point to the existing Todo node.

The issue which it demonstrates is that the client edge queries are not made because it incorrectly determines that the required data is already in the store.

In this example the issue can be avoided by:

• Removing the todos query in TodoApp, in this case the records will no longer be in the store and the edge queries are made.
• Moving the data required from the fragment within the @waterfall directive. It appears that the data within the fragment is non interrogated to see if it is required.
