fetch mock for react

React-Native Version

Why FetchMock ?

No fetch mock could be used easily for react.
So, I create one by myself.

Roadmap

• Combined with Mock.js
• Support exclude for some other path
• Proxy for other api server
• Delay for global and specific path
• Support RAP system

Usage

Import lib

1. using npm/yarn

   yarn add react-fetch-mock --dev
   npm install react-fetch-mock --save-dev

mocks/index.js

export default {
  '/api/path': ({ method, url, params, urlparams, headers }) => {
    const all = Mock.mock({
      'list|2': [{
        'id|+1': 1,
        'name': '@first @last',
        'age|18-54': 1,
      }]
    }).list;
    return all;   // default status is 200
  },
  '/api/path/{id}': ({ method, url, params, urlparams, headers }) => {
    const all = Mock.mock({
      'list|2': [{
        'id|+1': 1,
        'name': '@first @last',
        'age|18-54': 1,
        'urlid': urlparams.id,
      }]
    }).list;
    return all;
  },
  'POST /api/path': ({ method, url, params, urlparams, headers }) => {
    return {
      status: 201,
    };
  },
  'PUT /api/path/${id}': ({ method, url, params, urlparams, headers }) => {
    return {
      status: 204,
      id: urlparams.id,
    };
  },
}

index.js

import FetchMock from 'react-fetch-mock';
if (__dev__) {
  // attention: mocks file should be under `src/`
  window.fetch = new FetchMock(require('path/to/mocks/directory'), {
    delay: 200, // 200ms
    fetch: window.fetch,
    exclude: [
      'http://www.google.com',
      '/foo(.*)',
    ],
    proxy: [{
      path: '/path/for/proxy(.*)',
      target: 'http://other.proxy.server',
      process: (proxied, matches) => {
        return `${proxied.target}${matches[1]}`,
      },
    }],
  }).fetch;
}
// if __dev__ is true, it will back the data you defined in mock directory
fetch('/api/path', options);
fetch('/api/path', {
  delay: 2000,      // /api/path will delayed after 2000ms. Most of suitation, this won't be used usually.
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    name: 'John',
  }),
});
fetch('/api/path/123', {
  method: 'PUT',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    name: 'John2',
  }),
});
