Implementation method of using simulated interfaces in React and Vue

introduction:

In the development model of separation of front-end and back-end, front-end developers often need to wait for the completion of the back-end interface before functional development. To improve development efficiency, we can use it to simulate backend interfaces. It is a powerful front-end data simulation tool that intercepts front-end requests and returns simulated data. Below, we will explore how to use it in React and Vue projects.

1. Introduction

It is a JavaScript library for generating random data and intercepting Ajax requests. It allows front-end developers to develop without relying on actual back-end services by imitating back-end interfaces.

2. Use in React projects

Install
First, install in the React project:

npm install mockjs

Create mock data
Create a mock folder in the project and create a js file in it to define the mock data. For example, mock/:

import Mock from 'mockjs';
('/api/user', 'get', {
  'code': 200,
  'data|1-10': [{
    'id|+1': 1,
    'name': '@cname',
    'age|18-30': 20
  }]
});

Introduce mock data
Introduce mock data into the entry file of the project (such as):

import './mock/user';

Using the analog interface
Now, when you initiate an Ajax request in the React component, the simulated data is automatically intercepted and returned.

3. Use in Vue projects

Install
Also, install in Vue project:

npm install mockjs

Create mock data
Create a mock folder in the project and create a js file in it to define the mock data. For example, mock/:

import Mock from 'mockjs';
('/api/user', 'get', {
  'code': 200,
  'data|1-10': [{
    'id|+1': 1,
    'name': '@cname',
    'age|18-30': 20
  }]
});

Configuration
Create a file in the project root directory and configure the devServer's before hook:

 = {
  devServer: {
    before(app) {
      require('./mock/user')(app);
    }
  }
};

Using the analog interface
When an Ajax request is initiated in a Vue component, the request is intercepted and the simulated data is returned.

4. Use of summary

Advantages of using analog interfaces:

Improve front-end development efficiency without waiting for the back-end interface to complete;
Convenient front-end unit testing;
Various random data can be generated according to requirements.

Summarize:

This article details how to use it in React and Vue projects to simulate interface intercept requests. In this way, front-end developers can carry out development work more independently and efficiently. The mastered use will add icing on the cake to your front-end development skills.
