Alucard project

Alucard provides an HTTP api that allows you to create and manage a dynamic database using the JSON format.

How does it work? Alucard is a dynamic CRUD. It allows you to create tables for your database through an HTTP request and manage a CRUD http api.

Every action works under the same endpoint (POST) http:localhost:3000/api/v1/action

which receives two parameters action and. payload

Alucar uses Kafka and Camunda BPMN to manage the different flows according to the action. Upon receiving a request, the corresponding kafka event is dispatched, which will start a new instance of the BPM flow.
