Getting Started

$3

``
$ npm i react-bootstrap-sweetalert
`

> or

`
$ yarn add react-bootstrap-sweetalert
`

$3


`
const SweetAlert = require('react-bootstrap-sweetalert');
`
> or

`
import SweetAlert from 'react-bootstrap-sweetalert';
`

Recommended Usage

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.

----

Tip: Receiving an input value

If you're using input type, the value of the input will be sent to the onConfirm callback as the first argument.

` js
onConfirm={(response) => this.onRecieveInput(response)}
`

Custom Forms / Using Render Props

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.

`typescript jsx
title={"Uses render props"}
onConfirm={this.onConfirm}
onCancel={this.onCancel}
dependencies={[this.state.firstName, this.state.lastName]}
>
{(renderProps: SweetAlertRenderProps) => (


Your name is: {this.state.firstName} {this.state.lastName}

---

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'}
/>


type={'text'}
className="form-control"
value={this.state.lastName}
onKeyDown={renderProps.onEnterKeyDownConfirm}
onChange={(e) => this.setState({ lastName: e.target.value })}
placeholder={'Last name'}
/>

---

)}

`

Changes in version 5.2

* Added props.dependencies that re-renders the alert whenever the provided Array of dependencies value changes.
* Added new supported value of 'controlled' for props.type. If props.type === 'controlled' then props.onConfirm will return props.dependencies.
* Added support for using a function as your alert content/children, aka render props.

Reverses the order of the Confirm and Cancel buttons. Default positioning is [Cancel] [Confirm]

`typescript jsx
const [firstName, setFirstName] = useState('');
const [lastName, setLastName] = useState('');




Hello {{firstName}} {{lastName}}

setFirstName(e.target.value)} />
setLastName(e.target.value)} />
