How Servable server orchestrates a service?

Schema​

Servable takes the separation of concerns to the extreme by allowing every protocol to define a schema it needs to run. This schema has two main entries:

  • target: how does the protocol change the targetted model's schema, ie, which field to add
  • managed: the models the protocol needs to run

Final schema​

At runtime the Servable server computes the total schema for the whole app based on the multiple protocols that are called.

Lifecycle​

When the server is launched, the servable-engine performs the following tasks:

  • Launches an Express app
  • Computes the target database schema by aggregating the custom app tables and the protocols applied to those tables
  • Checks if a schema migration is necessary. It migrates the schema or not accordingly
  • Binds every protocol to the events triggered by the tables that use them
  • Exposes every protocol custom function
  • Registers jobs
