Getting Started

Installation

$ npm i react-bootstrap-sweetalert

or

$ yarn add react-bootstrap-sweetalert

Import

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.

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.

<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>

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

  CSS class added to cancel button.

• Type: string

• Default: ''

  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

• Default: undefined

  props.customIcon

  Either a string url for an image to use as the icon, or JSX/ReactNode.

• Type: ReactNode|string

• Default: undefined

  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

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>

props.focusConfirmBtn

If true the Confirm button will receive focus automatically. NOTE: Does not apply when props.type is 'input'

• Type: boolean

• Default: true

  props.focusCancelBtn

  If true the Cancel button will receive focus automatically. NOTE: Does not apply when props.type is 'input'

• Type: boolean

• Default: false

  props.required

  If props.type is 'input', this prop controls whether the input field is required to have a value.

• Type: boolean

• Default: true

  props.validationMsg

  If props.type is 'input' and props.required is true, this is the message to display when the user clicks confirm without entering a value.

• Type: string

• Default: 'Please enter a response!'

  props.validationRegex

  If props.type is 'input' and props.required is true, this Regex is used to validate input value.

• Type: RegExp

• Default: /^.+$/

  props.defaultValue

  If props.type is 'input', this is the default value for the input field.

• Type: number|string

• Default: undefined

  props.inputType

  If props.type is 'input', this is the default value for the input field.
