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! :beers:
See the demo with examples of common use cases and a live editor.
:alien: TAKE ME TO YOUR DEMO :alien:

$ 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.
SweetAlertRenderProps interface in types.ts for some information on the available render props.```typescript jsx <SweetAlert 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}
this.setState({ firstName: e.target.value })} placeholder={'First name'} />
<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>
)}
## 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.

----
### `props.title`
The text to display for the title. JSX/ReactNode allowed.
- Type: `ReactNode|string`
- Default: `undefined`
----
### `props.onConfirm`
Invoked when user clicks confirm button. Also invoked if user hits ENTER key.
- Type: `(response?: any) => any`
- Default: `undefined`
----
### `props.onCancel`
Invoked when user clicks cancel button. Also invoked if allowEscape is true and user hits ESCAPE key.
- Type: `() => any`
- Default: `undefined`
----
### `props.type`
The type of alert to display.
- Type: `'default'|'info'|'success'|'warning'|'danger'|'error'|'input'|'custom'|'controlled'`
- Default: `'default'`
> NOTE
> - If `props.type === 'controlled'` then `props.onConfirm` will receive `props.dependencies` as its first argument.
> - If `props.type === 'input'` then `props.onConfirm` will receive `props.dependencies` as its first argument.
----
### `props.btnSize`
The type of alert to display.
- Type: `'lg'|'sm'|'xs'`
- Default: `'lg'`
- Allowed values: `'lg'`, `'sm'`, `'xs'`
----
### `props.confirmBtnText`
Content of confirm button, or JSX/ReactNode.
- Type: `ReactNode|string`
- Default: `'OK'`
----
### `props.confirmBtnBsStyle`
Bootstrap style of confirm button.
- Type: `'default'|'primary'|'link'|'info'|'success'|'warning'|'danger'|'secondary'|'outline-{variant}'`
- Default: `'primary'`
----
### `props.confirmBtnCssClass`
CSS class added to confirm button.
- Type: `string`
- Default: `''`
----
### `props.confirmBtnStyle`
Inline style added to confirm button.
- Type: `CSSProperties`
- Default: `{}`
----
### `props.cancelBtnText`
Content of cancel button, or JSX/ReactNode.
- Type: `ReactNode|string`
- Default: `'Cancel'`
----
### `props.cancelBtnBsStyle`
Text of cancel button, or JSX/ReactNode.
- Type: `string`
- Default: `'link'`
- Recommended values: `'default'|'primary'|'link'|'info'|'success'|'warning'|'danger'|'secondary'|'outline-{variant}'`
----
### `props.cancelBtnCssClass`

----
### `props.cancelBtnStyle`
Inline style added to cancel button.
- Type: `CSSProperties`
- Default: `{}`
----
### `props.showCloseButton`
If set to true, then an X close button will be shown in the top right of the alert.
> 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 either `props.show` or by removing the `<SweetAlert />` in your render method.
- Type: `boolean`
- Default: `false`
----
### `props.reverseButtons`
Reverses the order of the Confirm and Cancel buttons. Default positioning is [Cancel] [Confirm]
- Type: `boolean`
- Default: `false`
----
### `props.customButtons`
Custom buttons to use in place of the default Confirm and Cancel buttons. Can render any JSX/ReactNodes here.
- Type: `ReactNode`

----
### `props.placeholder`
If `props.type` is `'input'`, this is the placeholder for the input field.
- Type: `string`
- Default: `undefined`
----
### `props.show`
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`
----
### `props.dependencies`
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`

```typescript jsx
const [firstName, setFirstName] = useState('');
const [lastName, setLastName] = useState('');
<SweetAlert dependencies={[firstName, lastName]}>
<h4>Hello {{firstName}} {{lastName}}</h4>
