A pure JavaScript React-Native dialog that follows closely the UI of its native counterpart while expanding its features.
- Support for iOS and Android (JavaScript API)
- A flexible declarative API
- Follows closely the UI of a native dialog/alert
- Can be used both as an alert and as an input prompt
- Can be injected with any component
Install the library using npm or yarn:
# Using npm:
$ npm install react-native-dialog
# Using yarn:
$ yarn add react-native-dialog
React-native-dialog exposes a set of components that can be used to build the UI of the dialog:
- Dialog.Container: This component is the root component of the dialog and all the other components should be nested inside it.
- Dialog.Title: A
Text
component styled as a native dialog title. - Dialog.Description: A
Text
component styled as a native dialog description. - Dialog.Button: A component styled as a native dialog button.
- Dialog.Input: A
TextInput
component styled as a native dialog input. - Dialog.Switch: A native
Switch
component with an optional label.
- Import react-native-dialog:
import Dialog from "react-native-dialog";
- Create a dialog and nest its content inside of it:
return (
<View>
<Dialog.Container>
<Dialog.Title>Account delete</Dialog.Title>
<Dialog.Description>
Do you want to delete this account? You cannot undo this action.
</Dialog.Description>
<Dialog.Button label="Cancel" />
<Dialog.Button label="Delete" />
</Dialog.Container>
</View>
);
- Then simply show it by setting the
visible
prop to true:
return (
<View>
<Dialog.Container visible={true}>
<Dialog.Title>Account delete</Dialog.Title>
<Dialog.Description>
Do you want to delete this account? You cannot undo this action.
</Dialog.Description>
<Dialog.Button label="Cancel" />
<Dialog.Button label="Delete" />
</Dialog.Container>
</View>
);
The visible
prop is the only prop you'll really need to make the dialog work: you should control this prop value by saving it in your state and setting it to true
or false
when needed.
The following example consists in a component (DialogTester
) with a button and a dialog.
The dialog is controlled by the dialogVisible
state variable and it is initially hidden since its value is false
.
Pressing the button sets dialogVisible
to true, making the dialog visible.
Inside the dialog there are two buttons that, when pressed, set dialogVisible
to false, hiding the dialog.
import React, { useState } from "react";
import { Button, StyleSheet, View } from "react-native";
import Dialog from "react-native-dialog";
export default function App() {
const [visible, setVisible] = useState(false);
const showDialog = () => {
setVisible(true);
};
const handleCancel = () => {
setVisible(false);
};
const handleDelete = () => {
// The user has pressed the "Delete" button, so here you can do your own logic.
// ...Your logic
setVisible(false);
};
return (
<View style={styles.container}>
<Button title="Show dialog" onPress={showDialog} />
<Dialog.Container visible={visible}>
<Dialog.Title>Account delete</Dialog.Title>
<Dialog.Description>
Do you want to delete this account? You cannot undo this action.
</Dialog.Description>
<Dialog.Button label="Cancel" onPress={handleCancel} />
<Dialog.Button label="Delete" onPress={handleDelete} />
</Dialog.Container>
</View>
);
}

To achieve a look even closer to the native iOS dialog you can provide your own component in the blurComponentIOS
prop of a Dialog.Container
and it will be injected in the dialog to be used as a background.
The blurComponentIOS
can be useful for example if you want to apply a native blur effect to the dialog.
Here is an example using react-native-blur
:
const blurComponentIOS = (
<BlurView style={StyleSheet.absoluteFill} blurType="xlight" blurAmount={50} />
);
return (
<View style={styles.container}>
<Dialog.Container visible={visible} blurComponentIOS={blurComponentIOS}>
<Dialog.Title>Account delete</Dialog.Title>
<Dialog.Description>
Do you want to delete this account? You cannot undo this action.
</Dialog.Description>
<Dialog.Button label="Cancel" onPress={handleCancel} />
<Dialog.Button label="Delete" onPress={handleConfirm} />
</Dialog.Container>
</View>
);
react-native-dialog
uses a thin abstraction on top of the React-Native's modal component. Any properties you add to Dialog.Container
are mapped through to the modal.
The modal has an onBackdropPress
property that can be used to register clicks on the backdrop.
Below is an example of how you can close the dialog by tapping outside.
const [visible, setVisible] = useState(true);
const handleCancel = () => {
setVisible(false);
};
return (
<Dialog.Container visible={visible} onBackdropPress={handleCancel}>
<Dialog.Title>Title</Dialog.Title>
<Dialog.Button label="Cancel" onPress={handleCancel} />
</Dialog.Container>
);
Thanks to the user @honaf who has kindly offered the react-native-dialog
namespace.
Also thanks to the user @leecade who offered the namespace react-native-alert
(which has not been used since "Dialog" seems to suit better this component) and to @tyxou for the entire codebase refactoring to hooks.
