A simple but flexible implementation of toast style notifications for React extracted from Sancho UI.

View the demo and documentation.

Features

• An imperative API. This means that you don't need to set component state or render elements to trigger notifications. Instead, just call a function.
• Render whatever you want. Utilize the render callback to create entirely custom notifications.
• Functional default styles. Import the provided css for some nice styling defaults or write your own styles.

Install

Install toasted-notes and its peer dependency, react-spring, using yarn or npm.

yarn add toasted-notes react-spring

Example

import toaster from "toasted-notes";
import "toasted-notes/src/styles.css"; // optional styles

const HelloWorld = () => (
  <button
    onClick={() => {
      toaster.notify("Hello world", {
        duration: 2000
      });
    }}
  >
    Say hello
  </button>
);

API

The notify function accepts either a string, a react node, or a render callback.

// using a string
toaster.notify("With a simple string");

// using jsx
toaster.notify(<div>Hi there</div>);

// using a render callback
toaster.notify(({ onClose }) => (
  <div>
    <span>My custom toaster</span>
    <button onClick={onClose}>Close me please</button>
  </div>
));

It also accepts options.

toaster.notify("Hello world", {
  position: "bottom-left", // top-left, top, top-right, bottom-left, bottom, bottom-right
  duration: null // This notification will not automatically close
});

Using Context

One downside to the current API is that render callbacks and custom nodes won't get access to any application context, such as theming variables provided by styled-components. To ensure that render callbacks have access to the necessary context, you'll need to supply that context to the callback.

const CustomNotification = ({ title }) => {
  const theme = useTheme();
  return <div style={{ color: theme.primary }}>{title}</div>;
};

const CustomNotificationWithTheme = withTheme(CustomNotification);

toaster.notify(() => <CustomNotificationWithTheme title="I am pretty" />);
