Hapi Faker

Hapi Faker helps you to create fake data to easily mock or test API endpoints.

Installation

Install this module with the command npm install --save hapi-faker, after that you are ready to register this module as a Hapi.js plugin.

var Hapi = require('hapi');
var hapiFaker = require('hapi-faker');
var server = new Hapi.Server();

server.register({
  register: hapiFaker,
  options: {...} // See the options documentation above
}, function(err){
  if(err)
    throw err;

  console.log('Ready to go!');
});

Usage

First of all, we need to add some schemas when registering Hapi Faker

var schema = {
  id: 'fake-email',
  type: 'object',
  properties: {
    email: {
      type: 'string',
      faker: 'internet.email'
    }
  },
  required: ['email']
};


server.register({
  register: hapiFaker,
  options: {
    schemas: [schema]
  }
});

After this you are ready to go. Also, you don't need to provide your schema at register time, with every method you can pass a full schema instead of your schema's ID.

As a plugin

To use Hapi Faker as a plugin, you just need to configure it in your route, passing a string containing the schema's ID or a full schema.

server.route({
  method: 'GET',
  path: '/fake/data',
  handler: function(request, reply){
    // This won't be triggered unless you hook this request
    // and disable Hapi Faker, to do so please read the options documentation
    reply({hello: 'world'});
  },
  config: {
    plugins: {
      faker: 'fake-email' // or a full JSF schema
    }
  }
});

As a handler

Passing faker as the handler will also work.

server.route({
  method: 'GET',
  path: '/fake/data',
  handler: {
    faker: 'fake-email' // or a full JSF schema
  }
});

As a reply method

For convenience, you can also call faker as a reply method

server.route({
  method: 'GET',
  path: '/fake/data',
  handler: function(request, reply){
    if(Math.random() < 0.5)
      return reply.faker('fake-email'); // or a full JSF schema

    reply('Not a fake data, this one is real.');
  }
});

Options

The options key when you register this plugin with Hapi, have the following signature:

• schemas an array containing schemas compatibles with JSON Schema Faker.
• hooks an object used to hook internal functions.
  • request a function that receives request and reply, to disable fake data on this request, you must return a false value. You can also return a promise that will resolve to a boolean value.
• jsf your own JSON Schema Faker instance.

Testing

git clone https://github.com/alanhoff/node-hapi-faker
cd node-hapi-faker && npm install
npm test

Todo

• [ ] Add inline documentation
• [ ] Allow context reference (payload, params, headers, query)
• [ ] Add documentation about hooks
