These are the docs for the latest stable release of the Bolt Design System. Looking for the upcoming release, v2.4.0-beta.0?

.boltrc Config

The order goes like this, as this list increases, the later override the earlier Order inspired by https://www.npmjs.com/package/rc#standards

  1. Each property has a default
  2. userConfig from .boltrc.js that's in same cwd as where bolt was ran, unless they use --config-file path/to/.boltrc.js
  3. Env Vars with bolt_ prefix; bolt_verbosity=1 will override config.verbosity - case matters!
  4. Certain command line options like bolt build --verbosity 5 - not every config option is overridable this way. Run bolt --help or bolt build --help to see options.

For both 3 & 4, it doesn't support deep merges, so only top level properties.
