Dockerized Flutter(web) + Golang(Gin) + PostgreSQL(with GORM) + Redis --> Template

This is inspired from the boilerplate at https://github.com/wzslr321/flutter_web_fullstack_boileplate

This repository is a fully dockerized application, which by default is a <b>web</b> app, but modyfing Dockerfiles lets to run it on <b> mobile </b> device too. Front-end is written in <b> Flutter </b>, Back-end in <b> Golang with Gin </b> framework. Databases are <b> PostgreSQL (with GORM) </b> and <b> Redis ( Redigo )</b>. Reverse proxy with <b> Nginx </b>. </i>

It does the following:

• It contains simple CRUD functions for both, Postgresql and Redis.
• It follows the OpenAPI spec mentioned in the openapi.yaml file
• It has a seed function that fills the databases from the json files in seed folder only if the DBs are empty when it starts
• Redis stores the full categories/items and are only get with full id or set
• Postgres stores the users, categories, sub-categories, tags and items references and relations. It is called for getting lists of categories/tags/items without specifying IDs
• A background asynchronous microservice (via go channels) is called for the Postgres storage while Redis is synchronous
• WebSockets push notification implementation with Kafka
• Items have a status field and delete only changes state to inactive
• An approval workflow is added for Items
