Run directly

Populate .env file with configuration. Current configuration variables is in internal/config/config.go. Example .env file file for fish shell:

# Database connect string format:
# postgresql://[user[:password]@][netloc][:port][/dbname][?param1=value1&...]
set -Ux DB_CONNECT_STRING 'postgresql://postgres:mysecretpassword@127.0.0.1:5432/<your db name>?sslmode=disable'
# To create a bot one can use botfather: https://telegram.me/BotFather
set -Ux BOT_TOKEN '<your telegram bot token>'
# Never assign listen address to 0.0.0.0 in production environment. This is just an example.
set -Ux LISTEN_ADDRESS 0.0.0.0:8080

To enable configuration you just need to source it:

source .env
