hapi-demo

This Repo is a Hapi plugin, that adds the possibility to define demo handlers.

The demo handler will be called instead of the original handler, if certain conditions are met.

A possible use-case is to setup routes with demo data, but without adding additional code into the existing code-base.

install

npm i --save hapi-demo

usage

register

Set up a hapi server and register the plugin.

import Hapi from 'hapi';
import HapiDemo from 'hapi-demo'

const server = new Hapi.Server();
server.register(HapiDemo)
  .then(() => {
    console.log('plugin has been registered successfully');
  });

route setup

When setting up routes, configure the demo handler if necessary:

import Joi from 'joi';

server.route({
  method: 'GET',
  path: '/test',
  handler(request, reply) {
    return reply('test handler called');
  },
  config: {
    plugins: {
      'hapi-demo': {
        shouldApplyHandler(request) {
          return request.query.demo;
        },
        handler(request, reply) {
          return reply('demo handler called');
        }
      }
    },
    validate: {
      query: Joi.object().keys({
        demo: Joi.boolean()
      })
    }
  }
});

Now when calling the /test route without any query parameters the normal hander will be called, but when calling it with query parameters like /test?demo=true, then the demo handler will be called.
