Taihei Framework

Prosperity through clarity. 天下泰平

Open-source Scala 3 libraries for the JVM and Scala.js. Small, typed, and built on clear rules, so that what you build on them can grow without surprises.

The Edo peace

Two and a half centuries of peace began with a clear set of rules.

From 1603 to 1868 Japan lived in peace under the Tokugawa shogunate. That peace rested on order: written rules for every domain, land surveyed and divided down to the plot, and everyone knowing where they stood. Within that order Edo, today's Tokyo, grew into one of the largest cities in the world.

We build software the same way. Clear rules, checked by the compiler rather than discovered in production, so that everything built on them can grow in peace. The Japanese still call that era 天下泰平, tenka taihei: great peace under heaven.

Libraries

The family

Every library is published to Maven Central under dev.taihei, cross-built for the JVM and Scala.js where it makes sense, and builds from a fresh clone with nothing but Mill and a JDK.

Tsuji

Languages, typed message families, per-language catalogues, ICU MessageFormat 2.0 and locale-aware number and date formatting. JVM and Scala.js. Formerly taihei-i18n, whose 4.x line still receives security fixes.

dev.taihei::taihei-tsuji · 5.0.0 on Maven Central

More to come

The family grows one library at a time, each one released when it meets the same rules: typed, tested on every platform, and documented.

What every library promises

  • OpenApache License 2.0. Anyone can clone, build and test without credentials or private repositories.
  • StableSemantic versioning, read strictly: a patch fixes, a minor adds, a major breaks, and a break comes with a migration guide.
  • CurrentCompiled with Scala's long-term support release, so your build and ours move together.
  • VerifiableEvery release is signed by the Taihei Framework release key, so you can check that what you download is what we built. How to verify
