using .env file

How to use env file instead of toml for sensitive information like credentials?

[levkk]

You can use crates like dotenvy (or dotenv) to load a .env file at startup, for example:

#[tokio::main]
async fn main() {
    dotenvy::dotenv().unwrap()
    /* ... */
}

Currently, rwf only supports the following env-sourced settings:

• RWF_DATABASE_URL which will configure the connection pool to use that database, e.g. postgres://localhost:5432/postgres
• RWF_DATABASE_USER if you only want to configure which user to connect with, everything else defaults to localhost
• RWF_DATABASE_NAME same as USER except it overrides the database name, again only localhost connections; for anything else, use RWF_DATABASE_URL
• RWF_LOG_QUERIES set this to any value to enable the ORM to log what queries it's executing

I'll add a todo on our roadmap to support configuring everything via environment variables, so you wouldn't have to use the TOML file if you didn't want to.
