feat: loading indicator #544

bobylito · 2017-10-31T14:08:02Z

This PR adds a loading indicator based on the proposal made here. However this version has changed a little:

the mechanics that determine if the search is stalled is implemented in the core of the library
there are options both on <InstantSearch> and <SearchBox>. The first one is for configuring the timer and the other is for displaying a loading indicator.

This is a POC implementation and the there is no design for the indicator (it's a red background) on purpose. Happy to discuss the API and the implementation.

This is definitely something that we can skip...

With this implementation all the connectors can propagate the information that the search is currently stalled (meaning that it seems that there are slow network issues). Currently it is only implemented in the searchbox.

@bobylito since you updated the yarn version under package.json you'll need to update also the travis script :)

Could you add the showLoading props as knobs on playground story?

bobylito · 2017-11-02T15:57:15Z

Oh yes I will do that 👌

mthuret · 2017-11-02T15:58:15Z

That's a very nice feature here :) Adding this loading info to other connector can be done quickly!

If I'm not mistaken there's only the spinner missing here. Do you need action/help of someone here @bobylito?

No I'm good for the implementation. I'm not quite settled on the implementation details for all InstantSearch. Once I'm sure of the consistency then I'll finish the feature :)

I'm wondering how to properly test that though... 🤔

anonrig · 2017-11-16T20:29:14Z

We should totally add this to autoComplete connector.

For consistency with InstantSearch.js

It was a mistake to try to fix the current behaviour of this flag. We should keep it as legacy and remove it during the next major.

And fix tests

We can probably create a variable for this.props.showLoadingIndicator && this.props.isSearchStalled since we are using this expression three times. It will be a bit less verbose in the code.

And do you have an idea for a name for this variable?

Nevermind, it's gonna be isSearchStalled :)

You could store the variable isSearchStalled directly into the store. Then we can avoid to keep track of the same value twice.

We could set this value required since isSearchStalled will be always pass to the component.

From a usage perspective, I would argue that this value is only useful if showLoadingIndicator is true and the only value that we really about is true. Considering that, do you think it should still be marked as required?

We can leave it as it it then, but when we define an optional props it's recommended to always give them a default value. So we can put a default value to false on the isSearchStalled. WDYT?

Ok WFM 👍

We can take advantage of your changes for rename the variable to searchResults. The third parameter pass to getProvidedProps is searchResults. The second one is searchState. So it's bit confusing to have searchResults called searchState 🙂

Sorry but I miss some things during the previous review. We could add some test cases for the SearchBox component.

We could add a test for this logic. Verify depending on the given props that the loading component is displayed or not (with a Snapshot).

We could use destructuring assignment for those variables.
