Lazy container and multi-container

Lazy ToastContainer

import React, { Component } from 'react';
import { toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
// Call it once in your app. At the root of your app is the best place
const App = () => {
const notify = () => toast("Wow so easy !");
return <button onClick={notify}>Notify !</button>;

The library will mount a ToastContainer for you if none is mounted.

Configure the ToastContainer when it is mounted on demand

The configure function accepts the same props as the ToastContainer. As soon as the container is rendered, the call to configure will have no effect.

autoClose: 8000,
draggable: false,
//etc you get the idea

Multi container support

To enable multiple container support, you have to pass enableMultiContainer and specify a containerId and use it in each toast, to do so add containerId to the toast's options object.

Note: adding enableMultiContainer prop to the <ToastContainer/ > will:

  • Check each toast to verify if its containerId match the container containerId so it can be rendered.
  • Ensure not to render any toast that has containerId.
  • Render any toast if both the toast and <ToastContainer/ > does not include containerId and containerId respectively.

A simple example to demonstrate multi toast container capability.

  • Notify A button will show a toast on the bottom left.
  • Notify B button will show a toast on the top right.
import React, { Component } from 'react';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
class App extends Component {
notifyA = () => toast('Wow so easy !', {containerId: 'A'});
notifyB = () => toast('Wow so easy !', {containerId: 'B'});
return (
<ToastContainer enableMultiContainer containerId={'A'} position={toast.POSITION.BOTTOM_LEFT} />
<ToastContainer enableMultiContainer containerId={'B'} position={toast.POSITION.TOP_RIGHT} />
<button onClick={this.notifyA}>Notify A !</button>
<button onClick={this.notifyB}>Notify B !</button>
