How should the application be structured into its main components? The goal is to be able to have multiple rest servers/webapps and multiple document processor components working togehter.
The following are the "main" modules. There may be more helper modules and libraries that support implementing a feature.
The code related to database access. It also provides the job queue. It is designed as a library.
Joex stands for "job executor".
An application that executes jobs from the queue and therefore depends
store module. It provides the code for all tasks that can be
submitted as jobs. If no jobs are in the queue, the joex "sleeps"
and must be waked via an external request.
It provides the document processing code.
It provides a http rest server to get insight into the joex state and also to be notified for new jobs.
It provides all the logic, except document processing, as a set of "operations". An operation can be directly mapped to a rest endpoint.
It is designed as a library.
This module contains the specification for the rest server as an
openapi.yml file. It is packaged as a scala library that also
provides types and conversions to/from json.
The idea is that the
rest server module can depend on it as well as
This is the main application. It directly depends on the
module, and each rest endpoint maps to a "backend operation". It is
also responsible for converting the json data inside http requests
to/from types recognized by the
This module provides the user interface as a web application.
