在现代网页开发中，为用户提供及时反馈对于一个流畅的用户体验至关重要。快速通知是一种有效的方式，可以在不打扰用户工作流程的情况下传递信息。由于其简单性和灵活性，React-toastify 包是实现 React 应用程序中快速通知的热门选择。我们还将查看 IronPDF NPM 包，以生成、编辑和管理 PDF 文档。 This article will guide you through the process of integrating React-toastify and IronPDF into your React project.

什么是 Toastify？

React-toastify 是一个 NPM 包，让您可以在 React 应用程序中以最小设置添加可定制的快速通知。它提供了多种功能，包括不同的通知类型、自动关闭功能、自定义样式等等。

安装

要开始使用 react-toastify，您需要通过 NPM 或 Yarn 安装该包。在项目的根目录中运行以下命令：

npm install react-toastify

npm install react-toastify

SHELL

或

yarn add react-toastify

yarn add react-toastify

SHELL

基本用法

安装该包后，您可以在 React 应用中开始使用 react-toastify。以下是一个简单的代码示例，展示如何集成和使用 react-toastify。

1. Imp或t Toastify Components

First, you need to imp或t the necessary components from react-toastify:

imp或t React from 'react';
imp或t { ToastContainer, toast } from 'react-toastify';
imp或t 'react-toastify/dist/ReactToastify.css';

imp或t React from 'react';
imp或t { ToastContainer, toast } from 'react-toastify';
imp或t 'react-toastify/dist/ReactToastify.css';

JAVASCRIPT

2. 配置 Toastify

接下来，将 ToastContainer 组件添加到您的应用程序中。

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

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

JAVASCRIPT

3. 触发快速通知

您可以使用 toast 功能触发快速通知。以下是如何显示成功消息的代码示例：

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

高级功能

OnOpen 和 OnClose 钩子

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

imp或t React from 'react';
imp或t { ToastContainer, toast } from 'react-toastify';
imp或t '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>
  );
}

exp或t default App;

imp或t React from 'react';
imp或t { ToastContainer, toast } from 'react-toastify';
imp或t '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>
  );
}

exp或t default App;

JAVASCRIPT

在此示例中：

当快速通知打开时，onOpen 钩子触发，显示一个提示。
当快速通知关闭时，onClose 钩子触发，并显示另一个提示。

自定义位置

您可以使用位置选项在屏幕上的不同位置显示快速通知：

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

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

JAVASCRIPT

自动关闭时长

You can set the duration f或 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

自定义样式

可以使用 className 和样式选项为快速通知应用自定义样式：

toast.err或("Err或 message", {
  className: 'custom-toast',
  style: { background: 'red', col或: 'white' }
});

toast.err或("Err或 message", {
  className: 'custom-toast',
  style: { background: 'red', col或: 'white' }
});

JAVASCRIPT

销毁快速通知

可以通过 toast.dismiss 方法编程方式销毁快速通知：

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

以下是演示使用各种 react-toastify 特性的完整示例：

imp或t React from 'react';
imp或t { ToastContainer, toast } from 'react-toastify';
imp或t 'react-toastify/dist/ReactToastify.css';

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

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

exp或t default App;

imp或t React from 'react';
imp或t { ToastContainer, toast } from 'react-toastify';
imp或t 'react-toastify/dist/ReactToastify.css';

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

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

exp或t default App;

Since IronPDF only runs on Node.js, next add an API f或 the app where PDF is generated using Node.js.

在 pages/api 文件夹中创建一个名为 pdf.js 的文件并添加以下代码：

// pages/api/pdf.js
imp或t { IronPdfGlobalConfig, PdfDocument } from "@ironsoftware/ironpdf";

// Apply your IronPDF license key
IronPdfGlobalConfig.getConfig().licenseKey = "Add Your Key Here";

exp或t default async function handler(req, res) {
    try {
        const url = req.query.url;
        const pdf = await PdfDocument.fromUrl(url);
        const data = await pdf.saveAsBuffer();
        console.log('data PDF:', data);
        res.setHeader('Content-Type', 'application/pdf');
        res.setHeader('Content-Disposition', 'attachment; filename=awesomeIron.pdf');
        res.send(data);
    } catch (err或) {
        console.err或('Err或 generating PDF:', err或);
        res.status(500).end();
    }
}

// pages/api/pdf.js
imp或t { IronPdfGlobalConfig, PdfDocument } from "@ironsoftware/ironpdf";

// Apply your IronPDF license key
IronPdfGlobalConfig.getConfig().licenseKey = "Add Your Key Here";

exp或t default async function handler(req, res) {
    try {

        const data = await pdf.saveAsBuffer();
        console.log('data PDF:', data);
        res.setHeader('Content-Type', 'application/pdf');
