How to use cloud database in vue

With the rapid development of cloud computing and big data technology, more and more companies and individuals are choosing to store their data on the cloud. For developers, how to build efficient applications on the cloud has become a must-have capability. At present, cloud database has become a trend to solve data storage. As a popular front-end framework, Vue also needs to master how to use cloud database in order to better realize data interaction and application development. This article will introduce in detail how to use cloud database for application development in Vue.

1. Introduction to vue application architecture

In vue application architecture, we usually adopt the following architecture:

1. Entry file: main.js, which mainly introduces the global Dependencies, defining routes, introducing binding stores (state management), creating Vue objects and other operations are the entrance to the entire application.

2. Routing file: router.js, which mainly defines routing and routing-corresponding components to implement page jumps.

3. State management file: store.js, which mainly defines the state (state), state modification functions (mutations) and submission behavior functions (actions) shared by each component to achieve global state management.

4. Page files: Each .vue component implements page display and interactive functions, especially playing an important role in the data request and rendering stages.

2. Use cloud database to implement data storage

Using cloud database in vue application mainly requires the following steps:

1. Create cloud database

On cloud platforms such as Tencent Cloud or Alibaba Cloud, you can choose to create the corresponding cloud database and record its database address (domain name/IP), port, user name, password and other information, and use it when connecting to the cloud database in the code arrive.

2. Install SDK

Currently, there are more and more database SDKs available, and almost all cloud companies provide SDKs based on different languages ​​and frameworks. For vue developers, it is recommended to choose Node.js SDK for installation.

npm install --save mysql

npm install --save pg

npm install --save redis

The above are three popular Nodes .js SDK, which can be selected and installed according to actual needs.

3. Connect to the cloud database

In the entry file of the vue application, that is, main.js or app.js, you can configure the cloud database connection.

node-mysql provides a very convenient API to operate the database:

var mysql = require('mysql');

connection = mysql.createConnection({

host : 'HOSTNAME',

user : 'USERNAME',

password : 'PASSWORD',

database : 'DATABASE'

});

connnection.connect();

Note that when using the cloud database, you need to configure the access permissions of the database. For details, please refer to the help documentation of the cloud platform.

4.API request example

In the vue component, we can implement API requests to the cloud database through APIs such as axios, vue-resource, and superagent. In specific applications, we call and implement them as needed. The following is an example of axios code:

import axios from 'axios'

export const getStudentInfo = params => {

return axios.get(http: //example.com/student/getStudentInfo, {

params: params

});

};

5. Page rendering Implementation

In the Vue component, after obtaining the cloud database data by calling the API, you can use vue's rendering mechanism to easily bind the data to the component's template to achieve page rendering.

3. Summary

As a popular front-end framework, Vue is very closely integrated with cloud databases. Through the introduction of this article, we have learned how to use cloud databases to implement data storage in Vue applications, including details such as creating cloud databases, installing SDK, connecting to cloud databases, API requests, and page rendering. I believe that for front-end developers, mastering the basic knowledge in this area can be helpful in application development and data interaction.
