Core API

Plural Rules

pico-intl uses the native Intl.PluralRules API for pipe-based plural messages. It is designed for common UI copy, not full MessageFormat parity.

{
  "cart.items": "{{count}} item | {{count}} items",
  "rank": "{{count}}st ~ {{count}}nd ~ {{count}}rd ~ {{count}}th"
}

Key points

• Pipe plurals cover common count-based UI copy.
• Variants are selected through native Intl.PluralRules.
• Use full MessageFormat tooling for exact selectors, offsets, or nested plural trees.

Next step

Copy the example into a small fixture, run the validation commands, and keep framework-specific routing, hydration, or SSR behavior covered by your app tests.
