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>

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 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

---
