React Toast Notifications with context provider

TL;DR Using the Context API is a great way to manage state in React applications, making it easy to create reusable components that can be easily integrated into your app. We've created a custom ToastContext and used it to display instant feedback to users through toast notifications.

React Toast Notifications with Context Provider: A Comprehensive Guide

As developers, we're always looking for ways to enhance our user's experience by providing instant feedback on actions taken within our applications. This is where toast notifications come in – a simple yet effective way to communicate with your users.

In this article, we'll explore how to implement React toast notifications using the Context API. We'll cover the basics of context providers, create a custom ToastContext, and integrate it into our application to provide instant feedback to our users.

Why Use Context Provider for Toast Notifications?

Using the Context API is an excellent way to manage state in React applications. By utilizing the context provider, we can decouple our toast notifications from any specific component or container, making them reusable throughout our app.

Imagine having a centralized location where you can manage all your toast notifications, and have them automatically displayed across your application without writing excessive code. Sounds like a dream come true!

Creating Our ToastContext

To get started, we'll create a new file called ToastContext.js. This will be the central hub for our toast notifications.

import React, { createContext, useState } from 'react';

const ToastContext = createContext();

const ToastProvider = ({ children }) => {
  const [toasts, setToasts] = useState([]);

  const addToast = (toast) => {
    setToasts((prevToasts) => [...prevToasts, toast]);
  };

  const removeToast = (id) => {
    setToasts((prevToasts) =>
      prevToasts.filter((toast) => toast.id !== id)
    );
  };

  return (
    <ToastContext.Provider value={{ toasts, addToast, removeToast }}>
      {children}
    </ToastContext.Provider>
  );
};

export { ToastProvider, ToastContext };

Here's what we have so far:

• We import createContext and useState from React.
• We create a new context called ToastContext.
• Our provider component (ToastProvider) is responsible for managing the state of our toast notifications using the useState hook.

Using Our ToastContext

Now that we've created our Context, let's see how to use it in one of our components. For this example, we'll create a simple ToastNotification component that will utilize our provider.

import React from 'react';
import { useContext } from 'react';
import { ToastContext } from './ToastContext';

const ToastNotification = () => {
  const { toasts, addToast, removeToast } = useContext(ToastContext);

  return (
    <div>
      {toasts.map((toast) => (
        <div key={toast.id} className="toast">
          <span>{toast.message}</span>
          <button onClick={() => removeToast(toast.id)}>X</button>
        </div>
      ))}
      <button
        onClick={() =>
          addToast({
            id: Math.random(),
            message: 'Hello, world!',
          })
        }
      >
        Show Toast
      </button>
    </div>
  );
};

export default ToastNotification;

In this example:

• We import useContext from React.
• We use the useContext hook to get an instance of our context (ToastContext) within our component.

Putting it all Together

Now that we have a basic understanding of how to create and use our Context, let's see how we can integrate it into our application.

import React from 'react';
import { ToastProvider } from './ToastContext';

const App = () => {
  return (
    <ToastProvider>
      <Header />
      <MainContent />
      <ToastNotification />
    </ToastProvider>
  );
};

And that's it! We've successfully integrated our Context into our application. From now on, whenever we want to display a toast notification, all we need to do is use the addToast function within our Context.

Conclusion

In this article, we explored how to implement React toast notifications using the Context API. By utilizing the power of context providers, we've created a reusable and centralized location for managing our toast notifications – no more tedious code or prop drilling!
