How to build a responsive newsletter application using Vue and Firebase Cloud Firestore

Foreword:
With the rapid development of the Internet, the spread of news information is getting faster and faster faster. As modern people, we always want to know all kinds of current news as soon as possible. So, in this article, I’ll cover how to build a responsive newsletter app using Vue and Firebase Cloud Firestore.

What is Vue and Firebase Cloud Firestore:
Vue is a progressive JavaScript framework for building user interfaces. It uses a componentized development model to help us build interactive Web more easily. app.

Firebase is a cloud service platform provided by Google. Cloud Firestore is a flexible and scalable NoSQL database designed to help us build the backend of our applications.

Preparation:
Before we start, we need to install Vue and Firebase. The Vue CLI can be installed using the following command:

npm install -g @vue/cli

Then, we need to create a new Vue project:

vue create news-app

Next, we need to create a new project in the Firebase console and enable Cloud Firestore database.

Set up Firebase Cloud Firestore:
In the Firebase console, click the "Create a new Firestore database" button and select "Start".

In the "Create Database" dialog box, select the "Start in test mode" option and click "Next".

Next, select a database location and click Next.

Finally, click "Start".

In the console, click the "Settings" button and select "Project Settings".

In the "General" tab, scroll down to the "Your Application" section and select "Import the following", select Vue.js.

Then, copy the contents of the configuration file into the .env.local file of your Vue project.

Install Firebase:
In the root directory of the Vue project, use the following command to install Firebase:

npm install firebase

Then, import it in the src/main.js file Firebase and Firestore:

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

// 初始化FirebaseApp
firebase.initializeApp({
  apiKey: process.env.VUE_APP_FIREBASE_API_KEY,
  authDomain: process.env.VUE_APP_FIREBASE_AUTH_DOMAIN,
  databaseURL: process.env.VUE_APP_FIREBASE_DATABASE_URL,
  projectId: process.env.VUE_APP_FIREBASE_PROJECT_ID,
  storageBucket: process.env.VUE_APP_FIREBASE_STORAGE_BUCKET,
  messagingSenderId: process.env.VUE_APP_FIREBASE_MESSAGING_SENDER_ID,
  appId: process.env.VUE_APP_FIREBASE_APP_ID
})

// 创建Firestore实例
const db = firebase.firestore()

// 导出Firestore实例
export default db

Building a newsletter application:
First, we need to create a component News.vue for displaying news, and add it in the src of the Vue project Created in the /components directory.

In News.vue, we will use Vue’s computed property to get the latest news data from Firebase and use Vue’s v- The for directive loops through each news item.

<template>
  <div>
    <h1 id="最新新闻">最新新闻</h1>
    <ul>
      <li v-for="news in latestNews" :key="news.id">
        <h2 id="news-title">{{ news.title }}</h2>
        <p>{{ news.content }}</p>
        <p>{{ news.date }}</p>
      </li>
    </ul>
  </div>
</template>

<script>
import db from '@/main'

export default {
  name: 'News',
  computed: {
    latestNews() {
      return db.collection('news')
        .orderBy('date', 'desc')
        .limit(10)
        .get()
        .then(querySnapshot => {
          const news = []
          querySnapshot.forEach(doc => {
            news.push({
              id: doc.id,
              ...doc.data()
            })
          })
          return news
        })
    }
  }
}
</script>

<style scoped>
h1 {
  font-size: 24px;
  font-weight: bold;
  margin-bottom: 20px;
}

li {
  margin-bottom: 20px;
}

h2 {
  font-size: 20px;
  font-weight: bold;
  margin-bottom: 10px;
}

p {
  font-size: 16px;
  margin-bottom: 10px;
}
</style>

Then, use the News component in the App.vue file in the root directory of the Vue project:

<template>
  <div id="app">
    <News />
  </div>
</template>

<script>
import News from '@/components/News'

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

Compile and run:
We just need to compile and run the Vue project locally using the following command:

npm run serve

Then, open the browser and visit http://localhost:8080, you will see a display Page for the latest news.
