How to create a high-quality newsletter application using Vue and Firebase Cloud Firestore

Newsletter applications play an important role in modern society and can help users get news and events in a timely manner latest information. This article will introduce how to use the Vue framework and Firebase Cloud Firestore to create a high-quality newsletter application, and provide specific code examples.

1. Preparation
Before we start, we need to install some necessary tools and libraries. First, make sure you have Node.js and npm installed. Then, use the following command on the command line to install the Vue CLI (scaffolding):

npm install -g @vue/cli

Next, create a new Vue project:

vue create newsletter-app

Go to the project directory:

cd newsletter-app

Install Firebase dependencies:

npm install firebase

2. Create a Firebase instance and initialize it
Create a new project in the Firebase console and enable the Cloud Firestore database. Then, get your project's configuration information from the console.

Create a new folder firebase in the src directory of the Vue project, and create a new file index.js in it. Then, copy the following code into index.js:

import firebase from 'firebase/app'
import 'firebase/firestore'

const firebaseConfig = {
  // 将你的Firebase配置信息替换成实际的值
  apiKey: 'YOUR_API_KEY',
  authDomain: 'YOUR_AUTH_DOMAIN',
  projectId: 'YOUR_PROJECT_ID',
  storageBucket: 'YOUR_STORAGE_BUCKET',
  messagingSenderId: 'YOUR_MESSAGING_SENDER_ID',
  appId: 'YOUR_APP_ID'
}

firebase.initializeApp(firebaseConfig)

export const db = firebase.firestore()

Remember to replace YOUR_API_KEY etc. with your actual configuration values.

3. Create Vue components
We will create two Vue components: one to display the news list and one to add news.

Create a new file NewsList.vue in the src/components directory, and copy the following code into the file:

<template>
  <div>
    <h1>时事通讯</h1>
    <ul>
      <li v-for="news in newsList" :key="news.id">
        {{ news.title }}
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      newsList: []
    }
  },
  mounted() {
    const newsRef = this.$firebase.firestore().collection('news')
    newsRef.onSnapshot((snapshot) => {
      const newsList = []
      snapshot.forEach((doc) => {
        newsList.push({...doc.data(), id: doc.id})
      })
      this.newsList = newsList
    })
  }
}
</script>

In the same Create a new file AddNews.vue in a directory, and copy the following code into the file:

<template>
  <div>
    <h2>添加新闻</h2>
    <form @submit.prevent="addNews">
      <label for="title">标题</label>
      <input type="text" id="title" v-model="title" required>
      <label for="content">内容</label>
      <textarea id="content" v-model="content" required></textarea>
      <button type="submit">提交</button>
    </form>
  </div>
</template>

<script>
export default {
  data() {
    return {
      title: '',
      content: ''
    }
  },
  methods: {
    addNews() {
      const newsRef = this.$firebase.firestore().collection('news')
      newsRef.add({ title: this.title, content: this.content })
      this.title = ''
      this.content = ''
    }
  }
}
</script>

4. Configure routing
Open src/router/index. js file, and insert the following code into the route definition:

import NewsList from '@/components/NewsList.vue'
import AddNews from '@/components/AddNews.vue'

const routes = [
  {
    path: '/',
    name: 'NewsList',
    component: NewsList
  },
  {
    path: '/add',
    name: 'AddNews',
    component: AddNews
  }
]

const router = createRouter({
  history: createWebHistory(),
  routes
})

5. Integrate Firebase and Vue
Open the src/main.js file, and insert the following code Insert into the file:

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import { db } from './firebase'

Vue.prototype.$firebase = db

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

6. Create the App.vue component
Open the src/App.vue file and replace the content in the file with the following code:

<template>
  <div id="app">
    <router-view></router-view>
    <router-link to="/add">添加新闻</router-link>
  </div>
</template>

<script>
export default {
  
}
</script>

7. Run the application
Now, we have completed all the necessary code and configuration. Enter the following command on the command line to start the application:

npm run serve

Open the browser and visit http://localhost:8080 to see the interface of the newsletter application. You can test the app by adding news.
