mocker-api that creates mocks for REST APIs. It will be helpful when you try to test your application without the actual REST API server.

Features:

🔥 Built in support for hot Mocker file replacement.
🚀 Quickly and easily configure the API via JSON.
🌱 Mock API proxying made simple.
💥 Can be used independently without relying on webpack and webpack-dev-server.

Quick Start

mkdir mocker-app && cd mocker-app

# Create a mocker configuration file based on rules
touch api.js

# Global install dependent.
npm install mocker-api -g

# Default port: 3721
mocker ./api.js

# Designated port
# Run server at localhost:8000
mocker ./api.js --host localhost --port 8000

Installation

you can put it the package.json config as a current project dependency.

npm install mocker-api --save-dev

Usage

mocker-api dev support mock, configured in mocker/index.js.

you can modify the http-proxy options and add the event listeners by adding the httpProxy configuration

const proxy = {
  // Priority processing.
  // apiMocker(app, path, option)
  // This is the option parameter setting for apiMocker
  _proxy: {
    proxy: {
      // Turn a path string such as `/user/:name` into a regular expression.
      // https://www.npmjs.com/package/path-to-regexp
      '/repos/(.*)': 'https://api.github.com/',
      '/:owner/:repo/raw/:ref/(.*)': 'http://127.0.0.1:2018',
      '/api/repos/(.*)': 'http://127.0.0.1:3721/'
    },
    // rewrite target's url path. Object-keys will be used as RegExp to match paths.
    // https://github.com/jaywcjlove/mocker-api/issues/62
    pathRewrite: {
      '^/api/repos/': '/repos/',
    },
    changeHost: true,
    // modify the http-proxy options
    httpProxy: {
      options: {
        ignorePath: true,
      },
      listeners: {
        proxyReq: function (proxyReq, req, res, options) {
          console.log('proxyReq');
        },
      },
    },    
  },

Delayed Response

You can use functional tool to enhance mock. #17

const delay = require('mocker-api/delay');
const noProxy = process.env.NO_PROXY === 'true';

const proxy = {
  'GET /api/user': {
    id: 1,
    username: 'kenny',
    sex: 6
  },
  // ...
}
module.exports = (noProxy ? {} : delay(proxy, 1000));

apiMocker

apiMocker(app, mockerFilePath[, options])
apiMocker(app, Mocker[, options])

Multi entry mocker file watching

const apiMocker = require('mocker-api');
const mockerFile = ['./mock/index.js'];
// or
// const mockerFile = './mock/index.js';
apiMocker(app, mockerFile, options)

Example

Using With Command

Base example

⚠️ Not dependent on webpack and webpack-dev-server.

# Global install dependent.
npm install mocker-api -g
# Run server
mocker ./mocker/index.js

Or you can put it the package.json config as a current project dependency.

{
  "name": "base-example",
  "scripts": {
+    "api": "mocker ./mocker"
  },
  "devDependencies": {
+    "mocker-api": "2.9.5"
  },
+  "mocker": {
+    "port": 7788
+  },
  "license": "MIT"
}

Using With Express

Express example

To use api mocker on your express projects.

⚠️ Not dependent on webpack and webpack-dev-server.

const express = require('express');
+ const path = require('path');
+ const apiMocker = require('mocker-api');

const app = express();

+ apiMocker(app, path.resolve('./mocker/index.js'))
app.listen(8080);

or

const express = require('express');
+ const apiMocker = require('mocker-api');

const app = express();

+ apiMocker(app, {
+   'GET /api/user': {
+     id: 1,
+     sex: 0
+   }
+ });

app.listen(8080);

Using With Webpack

webpack example

To use api mocker on your Webpack projects, simply add a setup options to your webpack-dev-server options:

Change your config file to tell the dev server where to look for files: webpack.config.js.

const HtmlWebpackPlugin = require('html-webpack-plugin');
+ const path = require('path');
+ const apiMocker = require('mocker-api');

module.exports = {
  entry: {
    app: './src/index.js',
  },
  output: {
    filename: '[name].bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
+ devServer: {
+   ...
+   before(app){
+     apiMocker(app, path.resolve('./mocker/index.js'), {
+       proxy: {
+         '/repos/(.*)': 'https://api.github.com/',
+         '/:owner/:repo/raw/:ref/(.*)': 'http://127.0.0.1:2018'
+       },
+       changeHost: true,
+     })
+   }
+ },
  plugins: [
    new HtmlWebpackPlugin({
      template: path.resolve('./public/index.html'),
      title: 'Webpack App Mocker API'
    })
  ],
};

Must have a file suffix! For example: ./mocker/index.js.

Let's add a script to easily run the dev server as well: package.json

{
  "name": "development",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
+    "start": "webpack serve --progress --mode development",
    "build": "webpack --mode production"
  },
  "keywords": [],
  "author": "",
  "license": "MIT",
  "devDependencies": {
    "html-webpack-plugin": "4.5.0",
    "mocker-api": "2.9.5",
    "webpack": "5.22.0",
    "webpack-cli": "4.5.0",
    "webpack-dev-server": "3.11.2"
  }
}

Mock API proxying made simple.

{
  before(app){
+   apiMocker(app, path.resolve('./mocker/index.js'), {
+     proxy: {
+       '/repos/(.*)': 'https://api.github.com/',
+     },
+     changeHost: true,
+   })
  }
}

Using With create-react-app

create-react-app example

To use api mocker on your create-react-app projects. create src/setupProxy.js and place the following contents in it:

+ const apiMocker = require('mocker-api');
+ const path = require('path');

module.exports = function(app) {
+  apiMocker(app, path.resolve('./mocker/index.js'), {
+    proxy: {
+      '/repos/(.*)': 'https://api.github.com/',
+    },
+    changeHost: true,
+  });
};
{
  .....
  "devDependencies": {
+    "mocker-api": "2.9.5"
  },
  ....
}
