A toast notification system for react

React Toast Notifications

A configurable, composable, toast notification system for react.

Install

yarn add react-toast-notifications

Use

Wrap your app in the ToastProvider, which provides context for the Toast descendants.

import { ToastProvider, useToasts } from 'react-toast-notifications'

const FormWithToasts = () => {
  const { addToast } = useToasts()

  const onSubmit = async value => {
    const { error } = await dataPersistenceLayer(value)

    if (error) {
      addToast(error.message, { appearance: 'error' })
    } else {
      addToast('Saved Successfully', { appearance: 'success' })
    }
  }

  return <form onSubmit={onSubmit}>...</form>
}

const App = () => (
  <ToastProvider>
    <FormWithToasts />
  </ToastProvider>
)

ToastProvider Props

For brevity:

• PlacementType is equal to 'bottom-left' | 'bottom-center' | 'bottom-right' | 'top-left' | 'top-center' | 'top-right'.
• TransitionState is equal to 'entering' | 'entered' | 'exiting' | 'exited'.

Toast Props

Hook

The useToast hook has the following signature:

const { addToast, removeToast, removeAllToasts, updateToast, toastStack } = useToasts();

The addToast method has three arguments:

1. The first is the content of the toast, which can be any renderable Node.
2. The second is the Options object, which can take any shape you like. Options.appearance is required when using the DefaultToast. When departing from the default shape, you must provide an alternative, compliant Toast component.
3. The third is an optional callback, which is passed the added toast ID.

The removeToast method has two arguments:

1. The first is the ID of the toast to remove.
2. The second is an optional callback.

The removeAllToasts method has no arguments.

The updateToast method has three arguments:

1. The first is the ID of the toast to update.
2. The second is the Options object, which differs slightly from the add method because it accepts a content property.
3. The third is an optional callback, which is passed the updated toast ID.

The toastStack is an array of objects representing the current toasts, e.g.

[
  { content: 'Something went wrong', id: 'generated-string', appearance: 'error' },
  { content: 'Item saved', id: 'generated-string', appearance: 'success' }
]

Replaceable Components

To bring each toast notification inline with your app, you can provide alternative components to the ToastProvider:

import { ToastProvider } from 'react-toast-notifications';

const MyCustomToast = ({ appearance, children }) => (
  <div style={{ background: appearance === 'error' ? 'red' : 'green' }}>
    {children}
  </div>
);

const App = () => (
  <ToastProvider components={{ Toast: MyCustomToast }}>...</ToastProvider>
);

To customize the existing component instead of creating a new one, you may import DefaultToast:

import { DefaultToast } from 'react-toast-notifications';
export const MyCustomToast = ({ children, ...props }) => (
  <DefaultToast {...props}>
    <SomethingSpecial>{children}</SomethingSpecial>
  </DefaultToast>
);
