Configuration

TypeStream is configured using a TOML file.

At startup, the server searches for a typestream.toml file using the TYPESTREAM_CONFIG_PATH environment variable. If not set, it searches:

1. The current working directory
2. The /etc/typestream directory

You can also set the full configuration via the TYPESTREAM_CONFIG environment variable.
