Thanks for feedback! It looks like a decent lib and I would recommend anyone who need richer i18n support (like plural forms) take a look.

As for a18n, it's a deliberate choice to use current format (JSON with extracted key/value pair) instead of standard like ICU messageformat. Here are reasons:

1. This lib is built to enable automated i18n workflow for existing projects (~200kloc), with minimal human interfere and impose minimal complexity for build configuration, in this regard current format is working great.

2. This lib is used by both projects, plugins and components in our company, so to keep its footprint down (in case it's not deduped by bundler), it means fewer features (like plural forms, date, list) are supported, and...

3. ...we originally planned to add support for ICU messageformat if these features are desired. But after two years in production, we found the demand is not too strong to justify the cost.
