Backend for development

It's a backend for frontend development or mobile application development. This program allows you to generate random text for your applications.

How to use it?

You need to download the server and create a .env file or set flags when starting the server.

What should be the file?

ADDRESS=0.0.0.0
PORT=8000
LOGLEVEL=debug
DATABASE_URL="postgresql://ilfey:QWEasd123@localhost:5432/go-back"
DATABASE_FILE=go-back.db
JWT_KEY=secret
JWT_LIFE_SPAN=24

What variables are needed?

• ADDRESS - The IP address that the server will listen on. Default: 0.0.0.0
• PORT - The port that the server will listen on. Dafault: 8000
• LOGLEVEL - Server logging level. Default: info
• DATABASE_URL - The URL of the PostgeSQL database where users will be stored. Default: postgresql://ilfey:QWEasd123@localhost:5432/go-back
• DATABASE_FILE - The SQLite database file. Used when it is not possible to connect to the PostgreSQL database. Default: go-back.db
• JWT_KEY - Secret key to generate JWT. Default: secret
• JWT_LIFE_SPAN - JWT life span in hours. Default: 24

What flags to set?

You can also start the server with the -h flag to see what flags exist. Flags will take precedence if you use flags and environment file at the same time.

• -a - The IP address that the server will listen on. Default: 0.0.0.0
• -p - The port that the server will listen on. Dafault: 8000
• -ll - Server logging level. Default: info
• -du - The URL of the PostgeSQL database where users will be stored. Default: postgresql://ilfey:QWEasd123@localhost:5432/go-back
• -df - The SQLite database file. Used when it is not possible to connect to the PostgreSQL database. Default: go-back.db
• -jk - Secret key to generate JWT. Default: secret
• -jls - JWT life span in hours. Default: 24
