Guidance on fetching/mutating lists

[mbrevda]

Hi -

Restful implementations generally offer the ability to select a list of entities or to "drill down" and get just a single one. Wondering if there is any official guidance on fetching these "lists"?

An example might be a list of users pulling from routes like users/ and users/${id}. Say we have two components: Users - lists all the users. User represents a single user. Is also responsible for mutating/updating the user:

|------------------------------------------|
| System Users                             | <--- Users component
|                                          |
| |--------------------------------------| |
| | Name: User 1                         | |  <--- User component
| |--------------------------------------| |
|                                          |
| |--------------------------------------| |
| | Name: User 2                         | |  <--- User component
| |--------------------------------------| |
|------------------------------------------|

The challenge is keeping the parts of the cache in sync while minimizing network traffic.

1. How could the data be loaded so that cache for both users/ and user/1 is set? (the is no need to load user/1 from the server at all)
2. How should the data be mutated so that both users/ and user/1 are updated? (seems wasteful to reload users/ from the server)

Thanks!
