Teravoz challenge

Code Challenge Teravoz (fullstack)

App developed to fulfill requirements on fullstack challenge.

Dependencies

• Nodejs v10.12.0 NVM
• Docker Install overview and guides. (it's not obligatory)

How to run the app

Setup

1. After clone repo, inside root directory, execute: make setup

2. If you have docker installed, you can use make docker-build and after build concluded run make docker-run.

   • If you prefer to run without docker, execute with make production.

3. For development purposes, is better run with make dev. Because it do more hot reload modules and restarts if you need to modify some code.

4. When the application starts, you have three available addressess:

   • Client to redirect posts on http://localhost:3002/webhook/.

     • This will handle data send with POST method, savied the caller number inside data, if it's a number that's not found in customer list and redirect to an agent in queue 900. Because that caracterize a new customer.

     • If receive payload with a number that's already exists, will only get the caller number from data payload, and update a agent on queue 901 with this informations.

   • Front end dashboard to see what agents already in call and the caller number. http://localhost:5000/. When you update the data in webhook endpoint, have to reload the page to see the agents status change. In a future i pretend to implement io.socket to see in realtime.

   • The data schemas are available in http://localhost:3000.

     • This is a awesome npm package (json-server), whos serves a json file like and API. If you want to reset the callers, or add more queues, or agents, simply edit the db.json file, and when save, it's ready to work.

Running Tests

• On app root, run: make test.

• Use make lint in development time, to help check some typos, syntax and other code quality rules with

Extras:

Help hand to test app behavior.

• Here are some call samples, to test the API: With this cURL, and some change in their_number propertie, you will easy verify the calls redirections.

      curl -X POST \
      http://localhost:3002/webhook/ \
      -H 'Content-Type: application/json' \
      -d '{
          "type": "call.standby",
          "call_id": "7f46c734-ffa5-447d-b08b-8709017b9d42",
          "code": "123456",
          "direction": "inbound",
          "our_number": "0800000000",
          "their_number": "11999921329",
          "their_number_type": "mobile",
          "timestamp": "1539855333"
      }'

Other tasks answers:

Proud of:

• I really have proud to participate and write the pieces of code for this challenge. It's represents a great meaninful and aggregate value to my developer background. Because it's my first "under pressure" nodejs development. My learn curve with docker is a gratitude and happiness to share too.

Ashamed of:

• One of shame piece of code on this challenge, the delegateCallApi, is a decision that i recognize it's not a good idea, the single responsability and separation of concerns are violently unrespected. I expect resolve it better and smart with some more analysis.

Feedback:

• What do you think about this challenge? In software programming carreer, i think, is like any other exercise. The more we pratice, make mistakes and learn from them, at least we should. It's a perspective from a interviewed.

  From interviewer perspective, would be a better manner to verify if knowledge degree of possible job partner fit with he's perspectives? I guess no.

• Is this a nice and reliable way of assessing your skills? I believe it is. And too, to measure the self organization, thought manner and others behaviors, that i do not have a better comprehension to share.

• Would you think of another way? No.

• Would you make it better? well, i see in others process the use of code platforms with some challenges presets and knowed algorithms for his difficult. And i believe it's a good way to analyse candidates. But i need to speech, i prefer the manner of this challenge. It's no bullshit.
