Before starting to see something you need to have installed all this stuff

• Postgress DB - currently v11.2
• Pipenv package dependency manager - currently v2018.11.26
• Node (and npm) runner and dependency manager - currently v12.4.0 (I recommend to use nvm for installing it)
• Python3 - currently v3.7.4
• Flask Framework - currently v1.1.1

• Project runs over https. So first create certificates and copy them in project root: "openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365" will output "cert.pem" and "key.pem"
• Create a project in https://console.developers.google.com/ and oauth2 credentials
• Get client_id and secret_id and copy them into .env
• Create a DB and update "SQLALCHEMY_DATABASE_URI" value with postgress URL (basically you should change flask_jwt_react with the name of your DB)
• run migrations "flask db init" "flask db migrate" and "flask db upgrade" a new user table will be created in the selected DB. The resultant migrations folder should be added to the repo.
• Run "yarn build:dev" to get a fresh JS build. (optional: "yarn watch" to modify the client codebase and see realtime changes)
• Run "yarn serve" to run server localhost

Finally! go to "https://localhost:5000" and enjoy it.
