snyk-config

This is a port of @snyk/config, an opinionated npm library which loads config from files and the environment.

It prefers:

• environment variables, prefixed with CONF_, as literals or JSON
• ${CONFIG_SECRET_FILE}
• config.${SERVICE_ENV}.json
• config.default.json

The ${env_vars} referenced above also have defaults:

• CONFIG_SECRET_FILE defaults to ./config.secret.json
• SERVICE_ENV defaults to local

Loaded values are merged, e.g.

config.default.json:

{"buy": {"potatoes": 5}}

config.secret.json:

{"buy": {"condamns": 1}}

env:

export CONF_buy__condamns=7
export CONF_debug=true

..will result in:

{"buy": {"condamns": 7, "potatoes": 5}, "debug": true}
