The Basics
- No Data + Fetching Data = LOADING
- Yes Data + Fetching Data = FETCHING
Why?
As long as the data we have is not invalid. We have no reason to hide it away from the user.
Examples from around the world
| Loading | Fetching |
 YouTube Loading State |
 YouTube Fetching State |
 Apollo App Loading State |
 Apollo App Fetching State |
 Fotmob Loading State |
 Fotmob Fetching State |
Important Exception
We must be careful not to trigger the fetching state when the data is invalid
Facebook Messenger Concept (Credit: Christoffer O. Jensen)
In this example. Moving between chats should always render the data on the screen invalid.
