axios-json-mock

Axios helper that allows to easily mock request

Installation

Using npm:

npm install axios-json-mock --save

axios-json-mock works on Node as well as in a browser, it works with axios v0.16.0 and above.

Example

Mocking a GET request

import axios from 'axios';
import AxiosJsonMock from 'axios-json-mock';

// Set default axios instance
const instance = new AxiosJsonMock(axios);

const responseWith = {
  200: [
    { id: 23, name: 'John Lennon' }
  ],
  400: {
    message: 'Bad Request'
  }
}
// arguments for instance are (request config, mock config)
instance({ url: '/users' }, {
  useMock: true,
  responseWith
})
  .then(response => console.log(response.data))

Add a specify status code

// arguments for instance are (request config, mock config)
instance({ url: '/users' }, {
  useMock: true,
  statusCode: 400,
  responseWith
})
  .catch(response => console.error(response))

To add a delay to responses, specify amout (in milliseconds)

const instance = new AxiosJsonMock(axios, { timeout: 1000 });

Using a mocks folder with json files

├── __dirname
│   ├── __mocks__
│   │   ├── userlist.json
│   │   ├── *.json
│   │   ├── *.json

userlist.json

{
  "200": [
    { "id": 23, "name": "John Lennon" }
  ],
  "400": {
    "message": "Bad Request"
  }
}

import axios from 'axios';
import AxiosJsonMock from 'axios-json-mock';

// Set default axios instance with mocks folder
const instance = new AxiosJsonMock(axios, { mockFolder: __dirname + '__mocks__' });

instance({ url: '/users' }, {
  useMock: true,
  mockName: 'userlist' // set json filename
})
  .then(response => console.log(response.data))
  

Turn off mocks and make real request

instance({ url: '/users' }, {
  useMock: false,
  mockName: 'userlist' // set json filename
})
  .then(response => console.log(response.data)) // real data
