Product Decisions This Supports
- Build vs. buy for locale data: Decide whether to maintain our own list of locale codes and display names or adopt a static, MIT-licensed dataset. This package answers that with pre-generated data, removing an ongoing data-hygiene burden from engineering.
- Internationalization (i18n) roadmap scoping: The package enumerates the full CLDR-derived locale universe (identifiers plus names in many languages). Use it to group locales by language/region, size the addressable audience per market, and decide which locales we actually ship in a given release instead of guessing.
- Locale selector and onboarding UX: Supports a concrete UX call — show locale names in the user's own language (native names) versus English-only labels — which has measurable impact on non-English onboarding and conversion.
- Profile, settings, and targeting features: Backs user language/region preference storage, validation of user-supplied locale codes, admin settings, content targeting, and analytics segmentation by locale.
- Runtime architecture decision: Static files vs. live CLDR/ICU integration. If the need is display, selection, and validation only, this pushes the decision toward shipping files rather than operating another service.
- Market prioritization: A canonical locale list is the raw material for ranking markets and sequencing localization investment, and it lets product and design prototype real selectors immediately.
When to Consider This Package
Consider adopting when:
- You need a canonical, complete list of locale identifiers with display names across many languages.
- You want pre-generated static data in multiple formats (JSON/PHP/YAML/XML/CSV) without owning a generation pipeline.
- Your use case is display, selection, or validation — not formatting or runtime logic.
- You value permissive licensing (MIT) and no runtime service or vendor dependency.
- You can pin a dataset version and refresh it on a cadence.
Look elsewhere when:
- You need formatting, parsing, pluralization, collation, or date/number formatting — use PHP
intl/ICU or symfony/intl.
- You need locale negotiation (Accept-Language parsing) or fallback chains — use dedicated middleware or a negotiation library.
- You need translated UI strings — that is a translation package (e.g.,
laravel-lang), not this one.
- You need flags, images, or locale metadata beyond names and codes.
- You need guaranteed current CLDR data with update SLAs — this is a static snapshot, and the project's governance and update cadence should be verified (moderate star count and thin repository metadata here).
- Laravel's built-in locale config plus an existing translation package already covers your needs, or you ship only a handful of locales you can cheaply hardcode.
Practical caution: this is a data-only package with no classes. Be deliberate about payload size — read only the language files you need rather than loading everything.
How to Pitch It (Stakeholders)
For executives: A low-risk, MIT-licensed static dataset that shortens the path to international expansion. No vendor lock-in, no runtime service, no recurring cost. It reduces build and maintenance time for locale pickers and preference settings, and it enables accurate native-language labeling that improves the non-English user experience and conversion.
For engineering: A small, predictable data dependency with no runtime logic and no new services. Installs via Composer; we consume only the files we need and can seed config or reference files directly. It removes the need to write and maintain our own locale generation script. Caveats to plan for: it is a static snapshot, so we pin a version and schedule refreshes, and we watch package size by loading only required languages.
For product and design: A trustworthy, complete source of locale codes and native names — the raw material for selectors, onboarding, settings, and market-targeting UI — without blocking on a data engineering effort. The caveat to set expectations: it supplies data only; formatting and translation logic still come from dedicated libraries.
