Nodejs webhook server

I have implemented a small webhook server using express and nodejs. Webhooks is a feature offered
by some web APIs such as Github, Facebook, Stripe and many others. Essentially it allows
API clients to register a URL that will receive an HTTP request in response to certain events.

Setting up the application:

1. git clone git@github.com:sakibshaik/nodejs-weblook-example.git
2. cd nodejs-weblook-example
3. npm install
4. Running tests : npm run test
5. start server : npm start

Server Details:

1. server listens on port 9876.
2. client can register by calling endpoint: /api/webhooks method: POST with payload:

{ "url": "https://postman-echo.com/post?hand=xxx", "token": "1312-3128-qwqw" }

3. Clients should be able to trigger all registered webhooks by making a POST request to /api/webhooks/test with a payload:

{"payload": ["aaaa", { "valid": "JSON" }]}

The application uses a fake data generator (located at helpers\fakeEventGenerators.js) which generates random data defaulted to every 5 seconds (which can be set by setting an environment variable GENERATORFREQUENCY in ms ) and publishes and 'OrderReceived' event using Javascript event emitters.

the processor (located at controller\processor.js) listens to the event 'OrderReceived' and triggers an batch update to all the registered clients.

If no client is registered console would print .... No Clients Registered yet .... .

On completion of a batch update a log on console: { processed: ['https://postman-echo.com/post?hand=Moore'], failed:['https://postman-echo.coms/post?hand=Runolfsson - Error: getaddrinfo ENOTFOUND postman-echo.coms postman-echo.coms:443' ] } processed array will have the url's of successfully updates. failed would have url's with failed updates with error message.

The application currently doesn't retry the failures.

Tests:

• Unit tests located at /tests/unit/
• Integration tests are located at /test/integration
