Server Side Application

Server Side Application

Router

• Dependencies are injected into the Router class, so It's a good file to start reading if you want to get familiar with the program.

Handlers

• functions that the router injects with dependencies, so that they can handle requests.

ScreenerCache

• on start grabs the latest screener in elasticsearch
• screener should be mostly static, so it might be best to hold in memory
  • technical uncertainty.
  • auto refresh cach, ditch cache, make cache refreshable from admin...
• updates will hit the screener cache and the database

ProgramCache

• holds all programs in memory
• program updates overwrite previous program data
• programs should be mostly static, so it might be best to hold in memory
  • technical uncertainty.
  • auto refresh cach, ditch cache, make cache refreshable from admin...

Notification Engine

• Used to register queries to programs
• translates between the application data model and the elasticsearch data model
  • query-converter.ts
• Uses submitted data to find applicable programs
• generally some of the ugliest code in the app.

general

Because YouCanBenefit is a thick-client application the api-server is somewhat neglected code. There is much opportunity for improvement in general. I'm in favor of doing a full rewrite using nest.js with an eye for modularizing the components and allowing for partial deployments.
