A pretty awesome search bar for React Native. It has a built in simple search capability which can be utilised by handing the component data
and providing a handleResults
function which will receive the filtered copy of the data
array.
The search function uses a depth-first algorithm to traverse the data and simply looks for an indexOf
the user input within all strings, numbers, and boolean values in the data.
Works on both iOS and Android.
(Rendered with the example in these docs and repository)

-
Use a ref to show and hide the search bar
ref={(ref) => this.searchBar = ref}
this.searchBar.show()
this.searchBar.hide()
-
Write your own search logic with
handleSearch
or provide somedata
and use the results handed back fromhandleResults
. -
Use your powers for good!
- Render the search bar component after the component it is supposed to display over. iOS handles this nicely with a
zIndex
of10
. Android elevation is set to 2. - The bottom of the search bar will have a thin border instead of a shadow.
