Progress bar for asynchronous requests?

[stain]

Raised by Jaroslav Martasek / Lilly:

As a lot of the results is loaded asynchronously it would be nice if some
sort of progress bar was present.

There should be a spinner when things are loading, if it's missing from any of the pages then please let me know. Not sure where the progress info would come from. The explorer asks the api for some results then waits until it gets them

[jmartasek]

E.g. https://explorer.openphacts.org/search?query=cocaine The spinner spins while the rows are loaded. When related counts are loaded (pharmacology, pathways) these just happen in the background without the user knowing.

E.g. 2 - https://explorer.openphacts.org/compounds/pharmacology?uri=http%3A%2F%2Fwww.conceptwiki.org%2Fconcept%2F13b4b707-8df0-4131-84b4-5433659e6ccf the first load does not have a spinner. The subsequent scroll-down loads do.

One of the reasons there are no spinners for the related counts is because they might be 0. Is this information also useful?

[ianwdunlop]

eg. Here a count of 0 is displayed inside a red badge

Or we could show it similar to how the 'object' view does it:

I would favour the second possibility. The red counts are getting too much attention for something that's not there (but which is not necessarily an error).

Or maybe you could add a search status in the header (next to Compounds 19, Targets 1). Something like:
Searching Compounds...
Searching Targets...
Fetching pharmacology data for compounds...
Fetching pathways for compounds...
...
Finished search.

This way the user would know what data is searched, even if no results are found.
