The author of SweetAlert2 (@limonte) is looking for short-term to medium-term working contracts in front-end, preferably OSS.


Download & install

$ npm install sweetalert2

Or grab from jsdelivr CDN

<script src="https://cdn.jsdelivr.net/npm/sweetalert2@9"></script>


1. Initialize the plugin by referencing the necessary files:

<script src="sweetalert2.all.min.js"></script>
<!-- Optional: include a polyfill for ES6 Promises for IE11 -->
<script src="https://cdn.jsdelivr.net/npm/promise-polyfill"></script>

You can also include the stylesheet separately if desired:

<script src="sweetalert2.min.js"></script>
<link rel="stylesheet" href="sweetalert2.min.css">


// ES6 Modules or TypeScript
import Swal from 'sweetalert2'

// CommonJS
const Swal = require('sweetalert2')

It's possible to import JS and CSS separately, e.g. if you need to customize styles:

import Swal from 'sweetalert2/dist/sweetalert2.js'

import 'sweetalert2/src/sweetalert2.scss'

2. Call the sweetAlert2-function after the page has loaded

  title: 'Error!',
  text: 'Do you want to continue',
  icon: 'error',
  confirmButtonText: 'Cool'

Integrations with major JS frameworks



Here are the keys that you can use if you pass an object into sweetAlert2:

backdrop true Whether or not SweetAlert2 should show a full screen click-to-dismiss backdrop. Can be either a boolean or a string which will be assigned to the CSS background property.

target 'body' The container element for adding modal into.
input null Input field type, can be text, email, password, number, tel, range, textarea, select, radio, checkbox, file and url.
width null Modal window width, including paddings (box-sizing: border-box). Can be in px or %. The default width is 32rem.

customClass '' A custom CSS class for the modal. If a string value is provided, the classname will be applied to the popup. If an object is provided, the classnames will be applied to the corresponding fields:
customClass: {
  container: 'container-class',
  popup: 'popup-class',

  actions: 'actions-class',
  confirmButton: 'confirm-button-class',
  cancelButton: 'cancel-button-class',
  footer: 'footer-class'
timer null Auto close timer of the modal. Set in ms (milliseconds). See also Swal.getTimerLeft(), Swal.stopTimer(), Swal.resumeTimer(), Swal.toggleTimer(), Swal.isTimerRunning() and Swal.increaseTimer().
timerProgressBar false If set to true, the timer will have a progress bar at the bottom of a popup. Mostly, this feature is useful with toasts.
animation true Deprecated and will be removed in the next major release, use showClass and hideClass instead.
If set to false, modal CSS animation will be disabled.
heightAuto true By default, SweetAlert2 sets html's and body's CSS height to auto !important. If this behavior isn't compatible with your project's layout, set heightAuto to false.
allowOutsideClick true If set to false, the user can't dismiss the modal by clicking outside it.
You can also pass a custom function returning a boolean value, e.g. if you want to disable outside clicks for the loading state of a modal.
allowEscapeKey true If set to false, the user can't dismiss the modal by pressing the Esc key. You can also pass a custom function returning a boolean value, e.g. if you want to disable the Esc key for the loading state of a modal.
allowEnterKey true If set to false, the user can't confirm the modal by pressing the Enter or Space keys, unless they manually focus the confirm button. You can also pass a custom function returning a boolean value.
stopKeydownPropagation true If set to false, SweetAlert2 will allow keydown events propagation to the document.
keydownListenerCapture false Useful for those who are using SweetAlert2 along with Bootstrap modals. By default keydownListenerCapture is false which means when a user hits Esc, both SweetAlert2 and Bootstrap modals will be closed. Set keydownListenerCapture to true to fix that behavior.
showConfirmButton true If set to false, a "Confirm"-button will not be shown. It can be useful when you're using custom HTML description.
showCancelButton false If set to true, a "Cancel"-button will be shown, which the user can click on to dismiss the modal.
confirmButtonText 'OK' Use this to change the text on the "Confirm"-button.
cancelButtonText 'Cancel' Use this to change the text on the "Cancel"-button.

reverseButtons false Set to true if you want to invert default buttons positions ("Confirm"-button on the right side).
focusConfirm true Set to false if you want to focus the first element in tab order instead of "Confirm"-button by default.
focusCancel false Set to true if you want to focus the "Cancel"-button by default.
showCloseButton false Set to true to show close button in top right corner of the modal.
closeButtonHtml '&times;' Use this to change the content of the close button.
closeButtonAriaLabel 'Close this dialog' Use this to change the aria-label for the close button.
showLoaderOnConfirm false Set to true to disable buttons and show that something is loading. Use it in combination with the preConfirm parameter.
scrollbarPadding true Set to false to disable body padding adjustment when the page scrollbar gets hidden while the modal is shown
preConfirm null Function to execute before confirm, may be async (Promise-returning) or sync.
Returned (or resolved) value can be:
  • false to prevent a popup from closing
  • anything else to pass that value as the result.value of Swal.fire()
  • undefined to keep the default result.value
See usage example.
imageUrl null Add a customized icon for the modal. Should contain a string with the path or URL to the image.
imageWidth null If imageUrl is set, you can specify imageWidth to describes image width in px.
imageHeight null Custom image height in px.
imageAlt '' An alternative text for the custom image icon.
inputPlaceholder '' Input field placeholder.
inputValue '' Input field initial value.

If the input type is checkbox, inputValue will represent the checked state.

If the input type is text, email, number, tel or textarea a Promise can be accepted as inputValue.
inputOptions {} If input parameter is set to "select" or "radio", you can provide options. Can be a Map or a plain object, with keys that represent option values and values that represent option text, or a Promise that resolves with one of those types.
inputAutoTrim true Automatically remove whitespaces from both ends of a result string. Set this parameter to false to disable auto-trimming.
inputAttributes {} HTML input attributes (e.g. min, max, autocomplete, accept), that are added to the input field. Object keys will represent attributes names, object values will represent attributes values.
inputValidator null Validator for input field, may be async (Promise-returning) or sync.
Returned (or resolved) value can be:
  • a falsy value (undefined, null, false) for indicating success
  • a string value (error message) for indicating failure
See usage example.
validationMessage null A custom validation message for default validators (email, url).
progressSteps [] Progress steps, useful for modal queues, see usage example.
currentProgressStep null Current active progress step. The default is Swal.getQueueStep()
progressStepsDistance '40px' Distance between progress steps.
onBeforeOpen null Function to run when modal built, but not shown yet. Provides modal DOM element as the first argument.
onOpen null Function to run when modal opens, provides modal DOM element as the first argument.
onRender null Function to run after modal DOM has been updated. Typically, this will happen after Swal.fire() or Swal.update(). If you want to perform changes in the modal's DOM, that survive Swal.update(), onRender is a good place for that.
onClose null Function to run when modal closes, provides modal DOM element as the first argument.
onAfterClose null Function to run after modal has been disposed.

You can easily reuse configuration by creating your own `Swal` with Swal.mixin({ ...options }):

Handling Dismissals

When an alert is dismissed by the user, the Promise returned by Swal.fire() will be resolved with an object { dismiss: reason } documenting the reason it was dismissed:

Reason Description Related configuration
Swal.DismissReason.backdrop The user clicked the backdrop. allowOutsideClick
Swal.DismissReason.cancel The user clicked the cancel button. showCancelButton
Swal.DismissReason.close The user clicked the close button. showCloseButton
Swal.DismissReason.esc The user clicked the Esc key. allowEscapeKey
Swal.DismissReason.timer The timer ran out, and the alert closed automatically. timer
