# CG Notes 12/20

## Dev environment
	uses Node / TS
		why? -> Very popular!
	Heroku component - Node program
	REST endpoint
	MongoDB storage -> Migrated from Postgres

## Architecture diagram
	2 modules
		1. endpoint to query whats in the system - API
		2. consumes data and sends to storage instance - Loader

## DB:
Validator with schemas
GraphQL API
everyone can use to access data

## Loader:
Another project
what?
 scheduler access upstream system API -> loads -> sends to content Gateway
 has SDK which does the sending
  no need to REST api call by hand
 2 use cases
	1. use the SDK on your local machine
	sdk on NPM
		@banklessdao/content-gat
	Push based API
	
	2. pull mechanics
	has a loader to pull th data and convert it and send to same SDK
	uses scheduler


**Highly encouraged to use VSCode - has a guide for setup**

## Project:
nx: tool for monorepo
	as many packages as you want within the monorepo
	manages it
	crutch: scripts folder - 95% of the things you want to do in the project
		ex: startup local docker env
using Prisma for postgres
	migration scripts to run first
	sometimes there will be timeout errors
		it will try to run the same job again
		grows exponentially


** DON"T SEND JUNK DATA TO THE PROD DB!! Next season will add validation **


## Code Structure:
own decorators
highly modular
	share code within project ( FE / BE ) with nx
	libs folder
		intended to be shared
		domain - domain logic
		banklessdao - published on NPM
	apps - can be deployed
		technically a FE - but ignore it
		domain - logic
		API
		loader
	utils
		loader - interfaces / types
			context - passed as params
			3 steps:
				1. register
				2. loading
				3. saving
			every loader has to have a root type
		scheduler - toad? scheduler
			no workers - K.I.S.S.
			very modular
			register loaders and it runs them for you
		graphql - converting schema to graphql type
			graphiql deployment available
	gateway
		remove/register schema
		receive/receiveBatch records
	SDK
		ContentGatewayClient
			register schema and save/savebatch data
			accepts OutboundDataAdapter - accepts HTTP
			no API keys yet - season 3 implementation
		Node app for both loader and 
		no frameworks - minimize third party risks
	API
		app to creat REST endpoints

** Using FPTS (article coming soon) / IOTS(runtime typesystem) **
