What is a service in Twake ?

You want to add new routes in an existing service, for instance add a feature to our channel service ? You are in the right place !

The backend is developed using a software component approach in order to compose and adapt the platform based on needs and constraints. The current section describes this approach, and how to extend it by creating new components.
The platform has the following properties:
A platform is composed of multiple components
A component has an unique name in the platform
A component can provide a service
A component can consume services from other components
A component has a lifecycle composed of several states: ready, initialized, started, stopped
A component lifecycle changes when a lifecycle event is triggered by the platform: init, start, stop
By creating links between components (service producers and consumers), components lifecycles are also linked together: A component going from ready to initialized will wait for all its dependencies to be in initialized state. This is automatically handled by the platform.
The platform currently have some limitations:
Components can not have cyclic dependencies: if component X requires a component which requires component X directly or in one of its dependencies, the platform will not start
Components can only have local dependencies.
Discover what is in a service
To unfold the internal ways of services in Twake, we will follow a simple request journey into our framework.
1.The requests starts from Twake Frontend or Postman for instance,
2.it then goes to a controller which validate the request parameters and extract them for the services,
3.the services uses the given parameters to get/set entities in database and returns a proper reply.
/web/controllers : where everything starts
This is where you declare the routing you want to use.
/services : where the magic happen
This is where you work for real, calling databases, sending websockets events, using tasks pushers etc.
/entities : where we keep the data
If you store data, you must define its data model and how it is stored in our database middleware.
This document is not finished, you can contribute to it on our Github.
