ICU MessageFormat v1 Plugin Now Available

The ICU MessageFormat v1 plugin is now available for inlang. If your project uses ICU MessageFormat (the format behind react-intl, @formatjs, and many other i18n libraries), you can now use inlang's full tooling ecosystem.

What's Supported

The plugin parses and exports ICU1 strings with full fidelity:

• Plurals and selectordinal including offset and exact matches (=0, =1)
• Select expressions for gender and other categorical choices
• Formatter functions like number, date, time with style parameters
• Octothorpe # substitution inside plural/selectordinal cases

{
  "items": "{count, plural, offset:1 =0 {no items} one {# item} other {# items}}",
  "rank": "{place, selectordinal, one {#st} two {#nd} few {#rd} other {#th}}"
}

Get Started

Add the plugin to your project.inlang/settings.json:

{
  "modules": [
    "https://cdn.jsdelivr.net/npm/@inlang/plugin-icu1@latest/dist/index.js"
  ],
  "plugin.inlang.icu-messageformat-1": {
    "pathPattern": "./messages/{locale}.json"
  }
}

That's it. Your existing JSON files work immediately. No migration required.
