3. Instance Circumstances of Every

3.1 React

React can be utilized with Java-based net frameworks like Spring MVC or Struts to construct net purposes. Right here’s an instance of how React can be utilized with Spring MVC to construct a easy net utility:

First, create a brand new Spring MVC challenge and add the mandatory dependencies for React and Babel. Babel is a JavaScript compiler that permits you to write trendy JavaScript code and have it transpiled to code that may run in older browsers:

<!-- pom.xml -->
<dependencies>
    <dependency>
        <groupId>org.webjars.npm</groupId>
        <artifactId>react</artifactId>
        <model>17.0.2</model>
    </dependency>
    <dependency>
        <groupId>org.webjars.npm</groupId>
        <artifactId>react-dom</artifactId>
        <model>17.0.2</model>
    </dependency>
    <dependency>
        <groupId>org.webjars.npm</groupId>
        <artifactId>@babel/core</artifactId>
        <model>7.16.0</model>
    </dependency>
    <dependency>
        <groupId>org.webjars.npm</groupId>
        <artifactId>@babel/preset-react</artifactId>
        <model>7.16.0</model>
    </dependency>
</dependencies>

Subsequent, create a easy React part that can show a message when the person clicks a button:

// src/fundamental/js/MyComponent.jsx
import React from 'react';

export default perform MyComponent() {
  const [message, setMessage] = React.useState('');

  const handleClick = () => {
    setMessage('Good day, world!');
  };

  return (
    <div>
      <button onClick={handleClick}>Click on me</button>
      <p>{message}</p>
    </div>
  );
}

Create a Spring MVC controller that can render the React part as HTML:

// src/fundamental/java/com/instance/MyController.java
bundle com.instance;

import org.springframework.stereotype.Controller;
import org.springframework.net.bind.annotation.GetMapping;

@Controller
public class MyController {
  @GetMapping("/")
  public String index() {
    return "index";
  }
}

Lastly, create an HTML file that can load the React part and transpile it utilizing Babel:

<!-- src/fundamental/sources/templates/index.html -->
<!doctype html>
<html>
  <head>
    <title>React Instance</title>
    <script src="https://www.javacodegeeks.com/webjars/react/17.0.2/umd/react.improvement.js"></script>
    <script src="/webjars/react-dom/17.0.2/umd/react-dom.improvement.js"></script>
    <script src="/webjars/@babel/core/7.16.0/dist/browser.js"></script>
    <script src="/webjars/@babel/preset-react/7.16.0/dist/browser.js"></script>
  </head>
  <physique>
    <div id="root"></div>
    <script sort="textual content/babel" src="/static/MyComponent.jsx"></script>
    <script sort="textual content/babel">
      ReactDOM.render(<MyComponent />, doc.getElementById('root'));
    </script>
  </physique>
</html>

While you run this utility and navigate to http://localhost:8080/, it’s best to see a button that claims “Click on me”. While you click on the button, the message “Good day, world!” ought to seem under it. That is only a easy instance, nevertheless it demonstrates how React can be utilized with a Java-based net framework like Spring

3.2 Vue.js

Right here’s a Vue.js code instance:

Suppose you might be constructing a easy climate utility that shows the present climate situations for a particular location. You determine to make use of Vue.js to construct the frontend of the applying.

First, you create a Vue.js part for displaying the present climate situations. The part fetches the present climate knowledge from an API after which shows it on the web page. The part has a type the place the person can enter a location after which click on a button to fetch the climate knowledge for that location.

<template>
  <div>
    <h1>Present Climate</h1>
    <type @submit.forestall="fetchWeather">
      <label>Location:</label>
      <enter v-model="location">
      <button sort="submit">Fetch Climate</button>
    </type>
    <div v-if="climate">
      <p>Location: {{ climate.identify }}, {{ climate.sys.nation }}</p>
      <p>Temperature: {{ climate.fundamental.temp }}°F</p>
      <p>Description: {{ climate.climate[0].description }}</p>
    </div>
  </div>
</template>

<script>
export default {
  knowledge() {
    return {
      location: '',
      climate: null
    }
  },
  strategies: {
    fetchWeather() {
      // AJAX request to fetch climate knowledge from API
      // then set this.climate to the response knowledge
    }
  }
}
</script>

Subsequent, you create one other Vue.js part for displaying an inventory of cities and their present climate situations. The part fetches an inventory of cities from an API after which fetches the present climate knowledge for every metropolis. The part shows town identify, temperature, and climate description in a desk.

<template>
  <div>
    <h1>Climate in Cities</h1>
    <desk>
      <thead>
        <tr>
          <th>Metropolis</th>
          <th>Temperature</th>
          <th>Description</th>
        </tr>
      </thead>
      <tbody>
        <tr v-for="metropolis in cities" :key="metropolis.id">
          <td>{{ metropolis.identify }}</td>
          <td>{{ metropolis.climate.fundamental.temp }}°F</td>
          <td>{{ metropolis.climate.climate[0].description }}</td>
        </tr>
      </tbody>
    </desk>
  </div>
</template>

<script>
export default {
  knowledge() {
    return {
      cities: []
    }
  },
  mounted() {
    this.fetchCities()
  },
  strategies: {
    fetchCities() {
      // AJAX request to fetch listing of cities from API
      // then loop by means of the listing of cities and fetch the climate knowledge for every metropolis
      // then set this.cities to an array of objects with town identify and climate knowledge
    }
  }
}
</script>

Once more, word that this code instance is only a simplified demonstration of how you can use Vue.js to construct a climate utility. In a real-world utility, you would want to implement the AJAX requests to the API your self or use a library like Axios or jQuery to deal with them.
