Getting Started with React Toastify: Enhance Your Notifications

介紹

在現代 Web 應用程式中,向使用者提供即時回饋對於保持流暢且引人入勝的體驗至關重要。通知在傳達重要事件(例如成功操作、錯誤或警告)而不中斷使用者工作流程方面發揮關鍵作用。這就是 React Toastify 發揮作用的地方。它是一個流行的庫,可以簡化向 React 應用程式添加可自訂 toast 通知的過程。與會打斷用戶旅程的傳統警報框不同,Toast 通知以微妙而優雅的方式出現,確保在不讓用戶脫離當前上下文的情況下傳達重要訊息。

借助 Toastify,開發人員可以輕鬆實現美觀且高度靈活的通知,允許自訂位置、樣式和時間,同時易於設定和使用。這使其成為希望透過有效的回饋機制增強使用者體驗的開發人員不可或缺的工具。

為什麼要使用 React Toastify?

Toast 通知在 Web 應用程式的許多常見場景中至關重要。例如,在使用者提交表單後,您可能想要顯示一條成功訊息以確認操作已完成,或在出現問題時顯示錯誤訊息。同樣,在處理 API 呼叫時,Toast 通知可以通知使用者結果,例如資料檢索成功或錯誤。

React-Toastify 可以無縫且有效率地處理這些通知。以下是它與預設瀏覽器警報和其他庫的一些主要優點:

  • 易於整合:設定簡單,只需最少的配置即可開始顯示通知。其直覺的 API 甚至適合初學者,讓開發人員無需複雜的設定即可快速添加 Toast 通知。
  • 可自訂的設計與定位: Toastify 的突出功能之一是它能夠自訂通知的外觀和行為。您可以輕鬆修改樣式,將它們放置在螢幕上的任何位置(例如,右上角、左下角),甚至建立自訂過渡。這種靈活性有助於在整個應用程式中保持一致的 UI/UX。
  • 支援自動和手動關閉:Toastify 讓您可以控制通知保持可見的時間。您可以選擇在指定時間後自動關閉或允許使用者手動關閉通知,從而根據上下文提供更好的使用者體驗。

  • 與預設瀏覽器警報的比較:預設瀏覽器警報具有侵入性,會阻止使用者交互,直到被關閉。另一方面,Toastify 提供非侵入式、優雅的 toast,出現在螢幕一角,並允許用戶繼續與頁面互動。它還支援更高級的功能,例如不同的 toast 類型(成功、錯誤、資訊)和更豐富的樣式,這是瀏覽器警報無法實現的。

透過將React-Toastify 整合到您的React 應用程式中,您可以獲得強大且可自訂的方式來管理通知,從而更輕鬆地向用戶提供回饋,同時保持流暢、現代的用戶體驗。

安裝和設定

React-Toastify 入門非常簡單,只需幾個步驟。以下是您在 React 專案中安裝和設定它的方法:

第 1 步:安裝 React Toastify

首先,您需要將 React-Toastify 套件加入您的專案中。在終端機中使用以下命令:

npm install react-toastify
登入後複製

第 2 步:在專案中匯入並使用 React Toastify

安裝套件後,您需要將 React Toastify 及其核心元件匯入到您的 React 專案中。至少,您應該匯入 ToastContainer,它負責在螢幕上呈現 toast 通知。

設定方法如下:

  1. 將 ToastContainer 和 toast 匯入到您的元件中。
  2. 確保 ToastContainer 包含在組件的 JSX 中。
  3. 使用 toast 函數觸發 toast 通知。

範例:

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

const App = () => {
  const notify = () => toast("This is a toast notification!");

  return (
    <div>
      <h1>React Toastify Example</h1>
      <button onClick={notify}>Show Notification</button>
      <ToastContainer />
    </div>
  );
};

export default App;
登入後複製

第三步:加入吐司樣式

不要忘記匯入 React Toastify CSS 檔案以套用通知的預設樣式:

import 'react-toastify/dist/ReactToastify.css';
登入後複製

Now, when you click the button, a toast notification will appear on the screen. The ToastContainer can be positioned anywhere in your app, and the toasts will automatically appear within it. You can further customize the appearance and behavior of the toast, which we will explore in the following sections.

Basic Usage of React Toastify

Once you have React Toastify set up, you can easily trigger various types of notifications based on user actions. Let's explore how to use it to display different toast notifications for success, error, info, and warning messages.

Example 1: Triggering a Success Notification

A common use case for a success notification is after a form submission. You can trigger it using the following code:

toast.success("Form submitted successfully!");
登入後複製

This will display a success message styled with a green icon, indicating a positive action.

Example 2: Error Notification

You can also display an error message when something goes wrong, such as a failed API call or form validation error:

toast.error("Something went wrong. Please try again!");
登入後複製

This shows a red-colored toast indicating an issue that requires the user's attention.

Example 3: Info Notification

Info notifications are useful when you want to inform the user about a status or update without implying success or failure. For example:

toast.info("New updates are available!");
登入後複製

Example 4: Warning Notification

If you need to alert the user to potential issues or important warnings, you can use the warning notification:

toast.warn("Your session is about to expire!");
登入後複製

This shows an orange toast, typically used for warnings or cautions.

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

const App = () => {
  const showToasts = () => {
    toast.success("Form submitted successfully!");
    toast.error("Something went wrong. Please try again!");
    toast.info("New updates are available!");
    toast.warn("Your session is about to expire!");
  };

  return (
    

React Toastify Notifications

); }; export default App;
登入後複製

With this code, clicking the button will trigger all types of notifications, allowing you to see how each one looks and behaves in your application.

Customizing Toast Notifications

One of the great features of React Toastify is its flexibility in customizing toast notifications to fit the look and feel of your application. You can easily adjust the position, duration, and even styling to suit your needs. Let’s walk through some of these customizations.

Customizing Position

React Toastify allows you to position toast notifications in various locations on the screen. By default, toasts are displayed in the top-right corner, but you can customize their position using the position property of the ToastContainer or while triggering individual toasts.

Available positions:

  • top-right (default)
  • top-center
  • top-left
  • bottom-right
  • bottom-center
  • bottom-left

Here’s an example of how to change the position of toasts globally via the ToastContainer:

<ToastContainer position="bottom-left" />
登入後複製

If you want to customize the position of individual toasts, you can pass the position option like this:

toast.success("Operation successful!", {
  position: "top-center"
});

登入後複製

This will display the success notification at the top-center of the screen.

Adjusting the Auto-Dismiss Timer

toast.info("This will disappear in 3 seconds!", {
  autoClose: 3000
});
登入後複製

If you want the toast to stay on screen until the user manually dismisses it, set autoClose to false:

toast.warn("This requires manual dismissal.", {
  autoClose: false
});

登入後複製

Customizing Toast Styling

React Toastify provides the flexibility to style your toasts either through CSS classes or inline styles. You can pass a custom CSS class to the className or bodyClassName options to style the overall toast or its content.
Here’s an example of using a custom CSS class to style a toast:

toast("Custom styled toast!", {
  className: "custom-toast",
  bodyClassName: "custom-toast-body",
  autoClose: 5000
});
登入後複製

In your CSS file, you can define the styling:

.custom-toast {
  background-color: #333;
  color: #fff;
}

.custom-toast-body {
  font-size: 18px;
}

登入後複製

This gives you complete control over how your notifications appear, allowing you to match the toast design with your application’s overall theme.

Advanced Features of React Toastify

React Toastify offers useful features to enhance the functionality of your toast notifications. Here's how you can leverage progress bars, custom icons, transitions, and event listeners.

Progress Bars in Toast Notifications

By default, React Toastify includes a progress bar that indicates how long the toast will stay visible. To disable the progress bar:

toast.info("No progress bar", { hideProgressBar: true });
登入後複製

Custom Icons and Transitions

You can replace default icons with custom icons for a more personalized look:

toast("Custom Icon", { icon: "?" });
登入後複製

To apply custom transitions like Bounce:

toast("Bounce Animation", { transition: Bounce });
登入後複製

Adding Event Listeners to Toasts

React Toastify allows you to add event listeners to handle custom actions, such as on click:

toast.info("Click me!", { onClick: () => alert("Toast clicked!") });
登入後複製

You can also trigger actions when a toast is closed:

toast.success("Success!", { onClose: () => console.log("Toast closed") });
登入後複製

Best Practices for Using React Toastify

To ensure that toast notifications enhance rather than hinder the user experience, it's important to follow best practices. Here are some guidelines to consider:

  1. Gunakan Pemberitahuan dengan Berhemat

    Walaupun pemberitahuan boleh membantu, penggunaan berlebihan boleh mengecewakan atau mengalih perhatian pengguna. Tempah pemberitahuan roti bakar untuk kemas kini penting, seperti mengesahkan tindakan yang berjaya (cth., penyerahan borang) atau memaparkan mesej ralat yang memerlukan perhatian.

  2. Pilih Jenis Pemberitahuan yang Betul

    Gunakan jenis roti bakar yang sesuai (kejayaan, ralat, maklumat, amaran) untuk menyampaikan nada yang betul. Contohnya, mesej kejayaan harus digunakan untuk tindakan yang telah selesai, manakala amaran harus dikhaskan untuk isu yang berpotensi.

  3. Elakkan Menyekat Tindakan Pengguna

    Memandangkan roti bakar tidak mengganggu, ia tidak seharusnya menyekat interaksi pengguna yang penting. Paparkan pemberitahuan dengan cara yang tidak menghalang pengguna daripada meneruskan tugas mereka.

  4. Sesuaikan Masa Berdasarkan Konteks

    Tetapkan masa autotolak yang munasabah untuk roti bakar. Mesej ralat mungkin perlu kekal lebih lama, manakala pemberitahuan kejayaan boleh hilang dengan cepat. Untuk isu kritikal, pertimbangkan untuk membenarkan pengguna menolak pemberitahuan secara manual.

Kesimpulan

React-Toastify menjadikan pelaksanaan pemberitahuan dalam aplikasi React menjadi lancar dan cekap, menawarkan penyelesaian yang fleksibel untuk menyampaikan maklum balas masa nyata kepada pengguna. Dengan reka bentuk yang boleh disesuaikan, pilihan kedudukan dan sokongan untuk ciri lanjutan seperti bar kemajuan dan pendengar acara, ia memudahkan proses pemberitahuan sambil membenarkan kawalan yang hebat ke atas pengalaman pengguna.

Dengan mengikuti amalan terbaik dan menggunakan pemberitahuan roti bakar dengan bijak, anda boleh meningkatkan interaksi pengguna tanpa membebankan mereka. Untuk mendapatkan maklumat yang lebih terperinci dan kes penggunaan lanjutan, pastikan anda menyemak dokumentasi React Toastify rasmi.
