Ancheta is a web API that exposes a simple set of endpoints allowing to manage, cast and remove polls. It is indended to be used publicly by any user and implements no concept of authentication. It can be a good simple backend for frontend developers who want to develop a small website as starter project.

The configuration is straightforward and quite easy. This API is reliant on Google Recaptcha, so you must create yourself a google account and obtain the recaptcha key. You must also setup a PostgreSQL database.

Environment variables used:

RECAPTCHA__KEY=... your key here ...
DATABASE__CONNECTIONSTRING=... postgresql connection string ...

Ancheta offers a SignalR hub where clients can subscribe to a poll events, such as when a vote is casted a procedure is invoked on the client side. This allows the client to have a dynamic interface properly without implementing extra steps such as periodic polling to the server.

The exposed hub methods are in NotificationsHub. The procedures invoked on the client side hub can be found in INotificationsClient.

The hub endpoint is /notificationshub.

A docker image is available on dockerhub, you can use the latest image simply by pulling mehigh17/ancheta:latest.

Here is a docker-compose.yml sample allowing you to quickly set it up.

version: "3"
services:
  db:
    image: postgres
    restart: always
    environment:
      POSTGRES_USER: ${PG_USER}
      POSTGRES_PASSWORD: ${PG_PASSWORD}
      POSTGRES_DB: ${PG_DB}
  ancheta:
    image: mehigh17/ancheta
    depends_on: 
      - db
    ports:
      - "8080:5050"
    environment:
      RECAPTCHA__KEY: ${RECAPTCHA}
      DATABASE__CONNECTIONSTRING: ${CONNECTION_STRING}

Run docker-compose on it and the API will be available on http://localhost:8080.

You can use the following .env file if you don't have your own setup.

PG_USER=dbuser
PG_PASSWORD=dbpass
PG_DB=anchetadb

RECAPTCHA=6LeIxAcTAAAAAGG-vFI1TnRWxMZNFuojJ4WifJWe # !!! THIS IS A TEST ONLY SECRET KEY PROVIDED PUBLICLY BY GOOGLE, RECAPTCHA WILL ALWAYS BE VALID !!!
CONNECTION_STRING=User ID=dbuser;Password=dbpass;Host=db;Port=5432;Database=anchetadb;

Swagger is a perfect tool for you to explore the API. Ancheta must run in development mode in order for Swagger to be available. Swagger is going to be available at {host}/swagger.

To set Ancheta in development mode use ASPNETCORE_ENVIRONMENT=Development.

If you are willing to contribute, you should first fork this repository. Therefore, you should create your own branch (git checkout -b <name>) from master, since it is the development branch.
