Examples

An error message:

swal("Oops!", "Something went wrong!", "error");

A warning message, with a function attached to the confirm message:

• Using promises:

swal({
  title: "Are you sure?",
  text: "Are you sure that you want to leave this page?",
  icon: "warning",
  dangerMode: true,
})
.then(willDelete => {
  if (willDelete) {
    swal("Deleted!", "Your imaginary file has been deleted!", "success");
  }
});

• Using async/await:

const willDelete = await swal({
  title: "Are you sure?",
  text: "Are you sure that you want to delete this file?",
  icon: "warning",
  dangerMode: true,
});

if (willDelete) {
  swal("Deleted!", "Your imaginary file has been deleted!", "success");
}

A prompt modal, where the user's input is logged:

• Using promises:

swal("Type something:", {
  content: "input",
})
.then((value) => {
  swal(`You typed: ${value}`);
});

• Using async/await:

const value = await swal("Type something:", {
  content: "input",
});

swal(`You typed: ${value}`);

In combination with Fetch:

• Using promises:

swal({
  text: "Wanna log some information about Bulbasaur?",
  button: {
    text: "Search!",
    closeModal: false,
  },
})
.then(willSearch => {
  if (willSearch) {
    return fetch("http://pokeapi.co/api/v2/pokemon/1");
  }
})
.then(result => result.json())
.then(json => console.log(json))
.catch(err => {
  swal("Oops!", "Seems like we couldn't fetch the info", "error");
});

• Using async/await:

const willSearch = await swal({
  text: "Wanna log some information about Bulbasaur?",
  button: {
    text: "Search!",
    closeModal: false,
  },
});

if (willSearch) {
  try {
    const result = await fetch("http://pokeapi.co/api/v2/pokemon/1");
    const json = await result.json();
    console.log(json);
  } catch (err) {
    swal("Oops!", "Seems like we couldn't fetch the info", "error");
  }
}

Using with React

SweetAlert has tools for integrating with your favourite rendering library..

If you're using React, you can install SweetAlert with React in addition to the main library, and easily add React components to your alerts like this:

import React from 'react'
import swal from '@sweetalert/with-react'

swal(
  <div>
    <h1>Hello world!</h1>
    <p>
      This is now rendered with JSX!
    </p>
  </div>
)
