## What it is
A Ruby gem that exports i18n translations from YAML files to JSON for use in JavaScript applications, with a companion npm package for consuming them. It includes Rails integration and a CLI for initializing configuration and exporting locale files.

## Use cases
- export rails i18n translations to json for javascript
- share translations between ruby backend and js frontend
- generate locale json files from yaml
- filter which translation keys get exported to the frontend
- use i18n translations in a non-ruby javascript project

## When to choose
- you have a Ruby or Rails app and need translations in JavaScript
- you want configurable, pattern-based filtering of exported translation keys
- you want digest-based cache-busting filenames for locale files

## When to avoid
- your project has no Ruby tooling and you only need a JS i18n runtime
- you need runtime translation management or a translation CMS
- you need server-side rendering of translations handled entirely in Ruby

## Facets
- artifact type: library
- maturity: active
- function: internationalization, cli, serialization
- domain: web-development, frontend, developer-tools
- platform: ruby
- tags: i18n, translations, rails, json-export, ruby-gem, localization, nodejs, javascript, web-server
