How to create a newsletter application using Vue

In today's era of information explosion, people's demand for current affairs news continues to increase. To meet this need, we can use Vue to create a newsletter application. Vue is a popular JavaScript framework that helps us build interactive user interfaces.

Here is a step-by-step guide to help you create a newsletter application using Vue.

1. Preparation
   First, we need to create a new Vue project. You can use the Vue CLI to quickly create a project, which will generate a basic project structure for you. After installing the Vue CLI, you can create a new Vue project using the following command:

vue create news-app

2. Install the required dependencies
   After creating the project, we need to install some required dependencies rely. Run the following command in the project root directory:

cd news-app
npm install axios vue-router

• axios: a commonly used HTTP client that we will use to obtain news data.
• vue-router: The routing plug-in officially provided by Vue, used to manage different pages of the application.

3. Set up routing
   We need to set up routing in order to navigate to different pages in the application. Open the src/router/index.js file and modify it according to the following example:

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'
import News from '../views/News.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'home',
    component: Home
  },
  {
    path: '/news',
    name: 'news',
    component: News
  }
]

const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes
})

export default router

In the above code, we have defined two routes:

• / : Root path, corresponding to the Home component.
• /news: News path, corresponding to the News component.

4. Create components
   Next, we need to create two components: Home and News. Create these two components under the src/views folder and write related styles and templates.

Home.vue:

<template>
  <div>
    <h1>Welcome to News App</h1>
    <router-link to="/news">Go to News</router-link>
  </div>
</template>

<script>
export default {
  name: 'Home'
}
</script>

<style scoped>
h1 {
  color: blue;
}
</style>

News.vue:

<template>
  <div>
    <h2>Top News</h2>
    <ul>
      <li v-for="article in articles" :key="article.id">
        {{ article.title }}
      </li>
    </ul>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  name: 'News',
  data() {
    return {
      articles: []
    }
  },
  mounted() {
    this.fetchArticles()
  },
  methods: {
    fetchArticles() {
      axios.get('<API_URL>').then(response => {
        this.articles = response.data
      }).catch(error => {
        console.error(error)
      })
    }
  }
}
</script>

In the News component, we use the axios library to get news data. You need to replace with the actual news data interface.

5. Update App.vue
   We also need to update the App.vue file in order to display different pages in the application. Open src/App.vue and modify it as per the following example:

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
export default {
  name: 'App'
}
</script>

6. Run the Application
   Now we have finished writing our newsletter application. Run the following command to launch the application:

npm run serve

You will see the welcome page in your browser. Click the "Go to News" link and the application will jump to the news page and display the actual news data from the API.

Through the above steps, you have successfully created a simple newsletter application using Vue. In actual applications, you can add more functions according to your needs, such as user authentication, news classification, etc.
