boring_avatars

boring_avatars is a Ruby port of Boring Avatars. It provides a framework-independent SVG generator and an opt-in Rails View Helper.

require "boring_avatars"

svg = BoringAvatars.generate(
  "Maria Mitchell",
  variant: :beam,
  size: 64,
  colors: ["#264653", "#2A9D8F", "#E9C46A", "#F4A261", "#E76F51"]
)

Available variants are marble, beam, pixel, sunset, ring, and bauhaus.

Load the Rails binding explicitly:

gem "boring_avatars", require: "boring_avatars/bindings/rails"

Then use the helper from a view:

<%= boring_avatar(
  current_user.email,
  variant: :bauhaus,
  class: "avatar",
  aria: { label: current_user.name }
) %>

See the architecture documentation for the complete API and compatibility policy.

The gem ships both type signature formats:

• Sorbet RBI: rbi/boring_avatars.rbi
• RBS: sig/boring_avatars.rbs

Run bundle exec rake typecheck to validate both definitions. This runs Sorbet and Steep contract checks and fails unless every public API is covered in both formats with zero untyped Sorbet usages (100% public API type coverage). Tapioca can import the RBI exported from the gem's rbi/ directory, while RBS can load the installed gem signature by library name.

The gem is available under the MIT License. See THIRD_PARTY_NOTICES.md for the upstream Boring Avatars notice.
