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

Introduction:
Smart newsletter applications play an important role in today’s fast-paced society Role. This article will introduce how to build a smart newsletter application using Vue and Firebase Cloud Firestore. Vue is a popular JavaScript framework for building user interfaces. Firebase Cloud Firestore is a cloud database solution provided by Google for storing and synchronizing data. Combining these two powerful tools, we can easily build a newsletter app with real-time messaging and smart recommendations.

Step 1: Create a Vue project
First, we need to create a Vue project. Open the terminal and execute the following command:

vue create smart-news

Then follow the prompts to select the configuration that suits you to complete the creation of the project.

Step 2: Configure Firebase
Next, we need to set up a new project on Firebase.

1. Visit the Firebase console (https://console.firebase.google.com/).
2. Click the "Create Project" button and enter the name of the project as prompted.
3. In the project settings, click "Add App" and select the "Web" app.
4. Enter an appropriate app name and copy the configuration information provided by Firebase into our Vue application.

Open the root directory of the Vue project and find the main.js file in the src directory. Add the following code to the top of the file:

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

// 在此处粘贴Firebase配置信息

firebase.initializeApp(firebaseConfig)

export const db = firebase.firestore()

Step Three: Create a Firebase Collection
Create a collection called articles to store our article data. Open the Firebase console and click on the "Database" tab on the left. Then click the "Create Database" button and select "Production Mode". We chose "Production Mode" because it will set our database into protected mode and can only be accessed using Firebase's authentication mechanism.

Enter "articles" in the "Collection ID" input box and click "Next". Then select "Start Mode" and click "Enable".

Step 4: Add article data
Next, we need to add some sample article data to Firestore for subsequent use. Click on the "articles" collection in the Firestore console and click on the "Add Document" button. We can enter fields and values ​​one by one, or choose to use a predefined JSON format.

Sample article data:

{
  "title": "如何使用Vue和Firebase Cloud Firestore构建智能应用",
  "description": "本文介绍如何使用Vue和Firebase Cloud Firestore构建一个智能时事通讯应用。",
  "category": "技术",
  "timestamp": "2021-09-01 10:00:00"
}

Click "Save" to add our article data.

Step 5: Create Vue component
Now we can start creating our Vue component. Create a folder named "components" in the src directory, and then create a file named "Articles.vue" under the folder.

In Articles.vue, we will implement a component to display all articles and update them in real time.

First, we need to import Firestore's real-time update function into our Vue component. Add the following code at the top of Articles.vue:

import { db } from '../main'

Next, add the following code in the export options of the component:

export default {
  data() {
    return {
      articles: []
    }
  },
  mounted() {
    // 获取文章数据
    db.collection('articles').orderBy('timestamp', 'desc').onSnapshot(snapshot => {
      this.articles = snapshot.docs.map(doc => ({
        id: doc.id,
        ...doc.data()
      }))
    })
  }
}

Add the following code inside the template tag to render the article data:

<div v-for="article in articles" :key="article.id">
  <h2>{{ article.title }}</h2>
  <p>{{ article.description }}</p>
  <p>{{ article.category }}</p>
  <p>{{ article.timestamp }}</p>
</div>

Step 6: Complete routing and views
In order for us to access our article list page in the browser, we need to define routes and views.

Open the router.js file in the src directory and add the following code:

import VueRouter from 'vue-router'
import Articles from './components/Articles.vue'

const routes = [
  { path: '/', component: Articles }
]

const router = new VueRouter({ routes })

export default router

In App.vue, add the following code to the template tag:

<router-view></router-view>

Steps Seven: Run the application
Now that we have completed all the necessary settings and code, we can run our application and view the results.

Execute the following command in the terminal:

npm run serve

After that, open the browser and visit http://localhost:8080/, we will see our article list page, and when the Firestore When the article data changes, the page will be updated in real time.
