An awesome replacement for JavaScript's alert.
If you think I've done a good job, consider showing your support by buying me a beer. Cheers! 🍻

$ npm i react-bootstrap-sweetalert
or
$ yarn add react-bootstrap-sweetalert
const SweetAlert = require('react-bootstrap-sweetalert');
or
import SweetAlert from 'react-bootstrap-sweetalert';
It is recommended that you keep an alert in your state, and remove it when the onConfirm
or onCancel
callbacks are invoked.
You can have stackable alerts by keeping an array of alerts in your data store, and always providing the first alert in the array as the visible alert. When an alert is closed, remove it from the store.
See examples/redux
for a working example of how to implement stackable alerts with a Redux store.
If you're using input
type, the value of the input will be sent to the onConfirm
callback as the first argument.
onConfirm={(response) => this.onRecieveInput(response)}
If you want to build an alert that re-renders based on external state changes, or simply want to build a custom form, then you will find the render props pattern to be your best option.
- For re-rendering based on external state changes, use props.dependencies
- See the
SweetAlertRenderProps
interface in types.ts for some information on the available render props.
<SweetAlert
title={"Uses render props"}
onConfirm={this.onConfirm}
onCancel={this.onCancel}
dependencies={[this.state.firstName, this.state.lastName]}
>
{(renderProps: SweetAlertRenderProps) => (
<form>
Your name is: {this.state.firstName} {this.state.lastName}
<hr/>
<input
type={'text'}
ref={renderProps.setAutoFocusInputRef}
className="form-control"
value={this.state.firstName}
onKeyDown={renderProps.onEnterKeyDownConfirm}
onChange={(e) => this.setState({ firstName: e.target.value })}
placeholder={'First name'}
/>
<br />
<input
type={'text'}
className="form-control"
value={this.state.lastName}
onKeyDown={renderProps.onEnterKeyDownConfirm}
onChange={(e) => this.setState({ lastName: e.target.value })}
placeholder={'Last name'}
/>
<hr/>
</form>
)}
</SweetAlert>
- Added
props.dependencies
that re-renders the alert whenever the provided Array ofdependencies
value changes. - Added new supported value of
'controlled'
forprops.type
. Ifprops.type === 'controlled'
thenprops.onConfirm
will returnprops.dependencies
. - Added support for using a function as your alert content/children, aka render props.

NOTE: You must also implement
props.onCancel
in order for this props to work. This is because visibility of the component is controlled externally through eitherprops.show
or by removing the<SweetAlert />
in your render method.
- Type:
boolean
- Default:
false
Reverses the order of the Confirm and Cancel buttons. Default positioning is [Cancel] [Confirm]
- Type:
boolean
- Default:
false
Custom buttons to use in place of the default Confirm and Cancel buttons. Can render any JSX/ReactNodes here.
- Type:
ReactNode
- Default:
undefined

- Type:
ReactNode|string
- Default:
undefined
If props.type
is 'input'
, this is the placeholder for the input field.
- Type:
string
- Default:
undefined
If false, the alert will not be rendered.
Warning: Using this option should be a last resort, and is somewhat of an anti-pattern for this library.
The recommended way to control visibility is to only render a <SweetAlert/>
element when you want one to be displayed,
and remove it when the onConfirm
or onCancel
methods are called.
- Type:
boolean
- Default:
true
If you have external state that should trigger your alert to re-render it's content, you can provide an Array
of dependencies
.
Whenever the dependencies are changed, using ===
comparision, the content of the alert will be re-rendered.
- Type:
any[]
- Default:
true
Example
const [firstName, setFirstName] = useState('');
const [lastName, setLastName] = useState('');
<SweetAlert dependencies={[firstName, lastName]}>
<div>
<h4>Hello {{firstName}} {{lastName}}</h4>
<input value={firstName} onChange={(e) => setFirstName(e.target.value)} />
<input value={lastName} onChange={(e) => setLastName(e.target.value)} />
</div>
</SweetAlert>
