How can i use react-toastify from hook?

The toasts inherit ToastContainer’s props. Props defined on toast supersede ToastContainer’s props.

There are two ways you can use toasts in your application:

1. Define ToastContainer inside the component

import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
  
  const App = () => {
    notify = () => toast("Wow so easy !");

    return (
      <div>
        <button onClick={notify}>Notify !</button>

        // You can add <ToastContainer /> in root component as well.
        <ToastContainer />
      </div>
    );
  }

2. Call toast.configure() once in your app. At the root of your app is the best place.

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

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
  toast.configure()
  
  const App = () => {
    notify = () => toast("Wow so easy !");

    return (
        <button onClick={notify}>Notify !</button>
    );
  }

You can use either of them. I prefer the 2nd method because you only need to define toast.configure() which is quite clean way to add it.

You can add configuration as per your need like below:

toast.configure({
  autoClose: 8000,
  draggable: false,
  //etc you get the idea
});

EDIT

If you want to use toast hooks, then you must wrap your app with the ToastProvider to have access to its context elsewhere within your app.

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>
)
