How to show loading state?

[yrik]

Can't figure out how to show progress indicator while ajax requests.

What is the best way to handle that? Should I fire extra action that set isLoading: true when I start request and then extra action to set isLoading: false?

This is what I do, just put it in the promiseMiddleware.

Here’s an example: https://github.com/bananaoomarang/chapters/blob/master/shared/lib/promiseMiddleware.js

I handle it in the a SessionReducer, along with user/login state and whatever else.

Thank you!

@bananaoomarang it's became more interesting when I want to show several loading indicators for different areas :)

@yrik you can set isLoadingSomething flag manually in a reducer. Set it to true on LOAD_SOMETHING_REQUEST and remove on LOAD_SOMETHING + LOAD_SOMETHING_FAILURE
