react-native-js-only-modal
If you are new to react-native
you will find that react-native
already has a Modal component that you could already use.
Now the different between this and what react-native
already have is that, first this is only js
library, it dose not use any native code
and also dose not reuse react-native
Modal component like other libraries.
Which make it much faster at rendering and easier to customize.
Features
Smooth enter/exit animations Plain simple and flexible APIs Customizable backdrop styling Listeners for the modal animations start and ending Resize itself correctly on device rotation
Setup
The library available at npm install react-native-js-only-modal
Snack Example
usage
Since react-native-js-only-modal
dose not include any native code and use only js
then you need it to be able to reach the root of the app.
In APP
components add the Provider
around the whole component
import { Provider } from 'react-native-js-only-modal';
import { Provider } from 'react-native-js-only-modal';
const App =()=> {
return (
<Provider>
...Your components here
</Provider>
)
}
- Create a component and nest its content inside of it
import { Modal } from 'react-native-js-only-modal';
function WrapperComponent() {
// show the Modal by setting `visible` = true
const [visible, setVisible] = React.useState(true);
return (
<View>
<Modal visible={visible}>
<View style={{ flex: 1 }}>
<Text>I am the modal content!</Text>
</View>
</Modal>
</View>
);
}
The visible
prop is the only prop you'll really need to make the modal work: you should control this prop value by saving it in your wrapper component state and setting it to true or false when needed.
Modal
already has transparent
background so by setting style you can customize it however you like.

Available animations
I am using react-native-animatable for animations, so you can see there what animation it offers.
More than one Modal
When viewing more than one Modal
it works that the last visible Modal
gets on top of all other Modal
.
And this is done by specifing the zIndex
zIndex
default start value is 90000
you can increase
or decrease
this value by specifying zIndex
for Provider
Style size
Settings Modal
style height,width,minWidth,minHeight
to %
, will be calculated based on screen
or window
size
ScrollView
Modal
dose not containe ScrollView
so you have to add it if you want to use any.
