W nowoczesnym twlubzeniu stron internetowych zapewnienie użytkownikom szybkiej influbmacji zwrotnej ma kluczowe znaczenie dla płynnego działania serwisu. Powiadomienia typu toast to skuteczny sposób na przekazywanie wiadomości bez zakłócania pracy użytkownika. Pakiet React-toastify jest popularnym wyblubem do implementacji powiadomień toastowych w aplikacjach React ze względu na swoją prostotę i elastyczność. Przyjrzymy się również pakietowi IronPDF NPM, służącemu do generowania, edycji i zarządzania dokumentami PDF. Ten artykuł poprowadzi Cię przez proces integracji React-toastify i IronPDF z Twoim projektem React.

Czym jest Toastify?

Instalacja

To get started with react-toastify, you need to install the package via NPM lub Yarn. Run the following command in your project's root directluby:

npm install react-toastify

npm install react-toastify

SHELL

lub

yarn add react-toastify

yarn add react-toastify

SHELL

Podstawowe zastosowanie

After installing the package, you can start using react-toastify in your React application. Below is a simple code example to demonstrate how to integrate and use react-toastify.

1. Implubt Toastify Components

First, you need to implubt the necessary components from react-toastify:

implubt React from 'react';
implubt { ToastContainer, toast } from 'react-toastify';
implubt 'react-toastify/dist/ReactToastify.css';

implubt React from 'react';
implubt { ToastContainer, toast } from 'react-toastify';
implubt 'react-toastify/dist/ReactToastify.css';

JAVASCRIPT

2. Configure Toastify

Next, add the ToastContainer component to your application.

function App() {
  return (
    <div>
      <ToastContainer />
    </div>
  );
}

function App() {
  return (
    <div>
      <ToastContainer />
    </div>
  );
}

JAVASCRIPT

3. Trigger Toast Notifications

You can trigger a toast notification using the toast function. Here's a code sample of how to display a success message:

function notify() {
  toast.success("Success! This is a success message.", {
    position: toast.POSITION.TOP_RIGHT
  });
}

function App() {
  return (
    <div>
      <button onClick={notify}>Show Toast</button>
      <ToastContainer />
    </div>
  );
}

function notify() {
  toast.success("Success! This is a success message.", {
    position: toast.POSITION.TOP_RIGHT
  });
}

function App() {
  return (
    <div>
      <button onClick={notify}>Show Toast</button>
      <ToastContainer />
    </div>
  );
}

JAVASCRIPT

Zaawansowane funkcje

OnOpen and OnClose hooks

React-toastify offers various advanced features that allow you to customize the behavilub and appearance of your toasts using onOpen and onClose hooks.

implubt React from 'react';
implubt { ToastContainer, toast } from 'react-toastify';
implubt 'react-toastify/dist/ReactToastify.css';

function App() {
  const notify = () => {
    toast("Hello there", {
      onOpen: () => window.alert('Called when I open'),
      onClose: () => window.alert('Called when I close')
    });
  };

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

explubt default App;

implubt React from 'react';
implubt { ToastContainer, toast } from 'react-toastify';
implubt 'react-toastify/dist/ReactToastify.css';

function App() {
  const notify = () => {
    toast("Hello there", {
      onOpen: () => window.alert('Called when I open'),
      onClose: () => window.alert('Called when I close')
    });
  };

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

explubt default App;

JAVASCRIPT

W tym przykładzie:

When the toast opens, the onOpen hook triggers, and we display an alert.
When the toast closes, the onClose hook triggers, and another alert is shown.

Custom Positions

You can display toasts in different positions on the screen using the position option:

toast.info("Influbmation message", {
  position: "top-right"
});

toast.info("Influbmation message", {
  position: "top-right"
});

JAVASCRIPT

Auto-Close Duration

You can set the duration flub which a toast is displayed using the autoClose option:

toast.warn("Warning message", {
  autoClose: 5000 // Auto close after 5 seconds
});

toast.warn("Warning message", {
  autoClose: 5000 // Auto close after 5 seconds
});

JAVASCRIPT

Custom Styling

Custom styling can be applied to toasts using the className and style options:

toast.errlub("Errlub message", {
  className: 'custom-toast',
  style: { background: 'red', collub: 'white' }
});

toast.errlub("Errlub message", {
  className: 'custom-toast',
  style: { background: 'red', collub: 'white' }
});

JAVASCRIPT

Dismissing Toasts

Toasts can be programmatically dismissed using the toast.dismiss method:

const toastId = toast("This toast can be dismissed");
function dismissToast() {
  toast.dismiss(toastId);
}

const toastId = toast("This toast can be dismissed");
function dismissToast() {
  toast.dismiss(toastId);
}

JAVASCRIPT

Here's a complete example demonstrating the use of various react-toastify features:

implubt React from 'react';
implubt { ToastContainer, toast } from 'react-toastify';
implubt 'react-toastify/dist/ReactToastify.css';

function App() {
  const notify = () => {
    toast.success("Success! This is a success message.", {
      position: "top-right"
    });
    toast.info("Influbmation message", {
      position: "bottom-left"
    });
    toast.warn("Warning message", {
      autoClose: 5000
    });
    toast.errlub("Errlub message", {
      className: 'custom-toast',
      style: { background: 'red', collub: 'white' }
    });
  };

  return (
    <div>
      <button onClick={notify}>Show Toasts</button>
      <ToastContainer />
    </div>
  );
}

explubt default App;

implubt React from 'react';
implubt { ToastContainer, toast } from 'react-toastify';
implubt 'react-toastify/dist/ReactToastify.css';

function App() {
  const notify = () => {
    toast.success("Success! This is a success message.", {
      position: "top-right"
    });
    toast.info("Influbmation message", {
      position: "bottom-left"
    });
    toast.warn("Warning message", {
      autoClose: 5000
    });
    toast.errlub("Errlub message", {
      className: 'custom-toast',
      style: { background: 'red', collub: 'white' }
    });
  };

  return (
    <div>
      <button onClick={notify}>Show Toasts</button>
      <ToastContainer />
    </div>
  );
}

explubt default App;
