使用 Shrtcode 在 React 中构建 URL 缩短器

有时你可能需要将一个 URL 发送给几个人，而这个 URL 可能有额外的参数，这往往会使它变得很长。这可以使用 URL 缩短器快速解决。URL 缩短器是用于创建将用户重定向到指定 URL 的唯一 URL 的工具。这个新的 URL 更短，包含 URL 缩短器的站点地址和随机字符的组合。在本文中，我们将使用 React.js 和 Shrtcode URL 缩短器构建一个 URL 缩短器 Web 应用程序。

什么是 URL 缩短器？

URL 缩短是一种 Web 技术，其中统一资源位置 (URL) 可以显着减少长度，提供仍然指向指定网页的新唯一 URL。总体思路是将长网址减少为更短的格式，以便于记忆、跟踪、在消息中共享或在印刷工作中使用。

URL 缩短器是提供 URL 缩短服务的网站。这些站点提供维护原始 URL 和缩短 URL 之间连接的服务。他们负责将用户重定向到所需的网页。新的缩短 URL 包含 URL 缩短器的域地址，以及字符和数字的组合。提供 URL 缩短服务的流行网站的一些示例是Shrtco.de（我们将使用）、Bit.ly 、 T.co 、 Tiny URL、Rebrandly和Tiny.cc。

• 当网页地址包含搜索查询、分页或会话数据等参数时，尤其需要缩短 URL。这些参数使 URL 跨越多个字符，难以分发、共享或记忆，因此需要 URL 缩短器。
• 在编写书籍时，无论是软拷贝还是硬拷贝，长 URL 可能会超过一行，并且在硬拷贝的情况下，很难将其复制到 Web 浏览器中。
• 一些消息传递平台对消息也有字符限制，这会使发送长 URL 变得具有挑战性。
• URL 缩短器使 URL 更具吸引力，并且可以提高转化率。
• URL 缩短器提供服务以支付流量率，即在缩短的 URL 上执行的共享或点击次数。
• URL 缩短器易于使用，只需单击按钮即可缩短 URL。
• 缩短的 URL 可以防止您通过发送看起来可疑的粗大 URL 来吓唬别人。

在本教程中，我们将使用 Shrtco.de 构建一个 URL 缩短器。Shrtco.de 提供了一个免费的、易于使用的 API 来缩短 URL，无需事先的身份验证方法即可访问它。它安全且隐私友好。以下是您应该考虑使用 Shrtcode 来缩短 URL 的几个原因：

• Shrtco.de 不断确保缩短的 URL 始终重定向到所需的页面。多年来，各种 URL 缩短服务一直是黑客的目标，并被用来将用户重定向到预期结果之外的站点。
• 所有缩短的 URL 都会被定期扫描，作为针对恶意软件的先发制人措施。
• Shrtco.de 关心隐私。它不会跟踪访问者对缩短 URL 的访问，并且还提供了一项安全功能，可以为缩短的 URL 添加密码，以防止人们在未经授权的情况下访问您的网站。
• 如果用户愿意，Shrtco.de 可以通过将链接中的“shrtco.de”部分替换为“9qr.de”来缩短 URL。
• 除了文本 URL，如果您想要一个有趣的链接，Shrtco.de 还可以生成表情符号链接作为缩短的 URL。

构建 URL 缩短器

对于 URL 缩短器，我们将使用 React.js 框架。我们将需要一个简单的用户界面，其中包含一个输入字段、一个提交要缩短的 URL 的按钮、一个显示缩短的 URL 的框和一个copy to clipboard按钮。我们将使用TailwindCSS简单的应用程序样式。我们可以在App.js文件中创建它，如下所示：

import "./App.css";
import {React, useState} from "react";
function App() {
  return (
    <div className=" container h-screen flex justify-center items-center">
      <div className=" text-center">
        <h1 className=" text-2xl font-medium text-blue-500 mb-4">
          Our <span className=" text-yellow-400">URL Shortener</span>
        </h1>
        <div>
          <input
            className="outline-none border-2 border-blue-500 rounded-md backdrop-blur-xl bg-white/20 shadow-md px-3 py-3"
            type="text"
            placeholder="Enter link to be shortened"
          />
          <button className=" bg-blue-500 text-white px-8 py-3 ml-4 rounded-md">
            Submit URL
          </button>
        </div>
      </div>
    </div>
  );
}
export default App;

在上面的代码中，我们有一个简单的输入字段和一个按钮。如果我们使用npm start命令运行代码，我们会得到类似于下图的结果：

为了处理字段中的用户输入，我们将创建一个状态来管理它。

const [userInput, setUserInput] = useState("");

我们可以将其附加到输入字段value和onChange属性：

<input
  //...
  value={userInput}
  onChange={(e)=>{setUserInput(e.target.value)}}
/>

链接预览区

接下来，我们将添加一个显示缩短 URL 的区域。

const [shortenedLink, setShortenedLink] = useState("")

然后，我们在按钮后面添加预览区域和“复制到剪贴板”submit URL按钮。

//...
<div className="mt-5">
  {shortenedLink}
  <button className="border-2 border-blue-500 text-blue-500 font-medium px-5 py-2 ml-4 rounded-md">
    Copy URL to Clipboard
  </button>
</div>

我们将使用“react-copy-to-clipboard”包来实现“复制到剪贴板”功能。我们将在代码的顶层为此包添加一个导入：

import CopyToClipboard from "react-copy-to-clipboard";

我们将使用它，如下面的代码块所示：

<CopyToClipboard text={shortenedLink}>
  <button className="border-2 border-blue-500 text-blue-500 font-medium px-5 py-2 ml-4 rounded-md">
    Copy URL to Clipboard
  </button>
</CopyToClipboard>

在这里，该text属性引用单击按钮时将复制的内容。

ShrtCo.de 设置

要设置 Shrco.de，我们将使用axiosfetch 创建一个函数：

import axios from 'axios';
//...
  const fetchData = async () => {
  try {
    const response = await axios(
      `https://api.shrtco.de/v2/shorten?url=${userInput}`
    );
    setShortenedLink(response.data.result.full_short_link);
  } catch (e) {
    console.log(e);
  }
};

最后，我们将这个函数添加到Submit URL函数中：

<button
  className=" bg-blue-500 text-white px-8 py-3 ml-4 rounded-md"
  onClick={() => {
    fetchData();
  }}
>
  Submit URL
</button>

现在，如果我们在输入字段中添加一个链接并单击提交按钮，我们会得到一个缩短的链接。

结论

在本教程中，我们了解了 URL 缩短器、它们的好处，以及我们如何使用 React.js 和 Shrtco.de 轻松构建一个。

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

• React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
• React.js and React Native have similar syntax and workflows, but their implementation is quite different.
• React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
• React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

* React.js Developer Salary by Country

• United States- $120,000
• Canada - $110,000
• United Kingdom - $71,820
• The Netherlands $49,095
• Spain - $35,423.00
• France - $44,284
• Ukraine - $28,990
• India - $9,843
• Sweden - $55,173
• Singapore - $43,801

In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.

However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.

It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.

As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.

How to Hire React.js Developers?

• Conduct thorough candidate research, including portfolios and areas of expertise.
• Before you sit down with your interviewing panel, do some homework.
• Examine the final outcome and hire the ideal candidate.

Why is React.js Popular?

React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.

Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.

Final thoughts:

As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.
