A monorepo of small, focused libraries for JavaScript environments — browsers, Node.js, and other modern runtimes.
Everything here is written in TypeScript and ships with type definitions, so you get autocompletion and type safety out of the box whether your own project uses TypeScript or plain JavaScript. The packages are ESM-only, tree-shakeable, and keep external dependencies to a minimum, so you only pay for what you actually import.
Each package is published independently to npm, using the @zemd and @logtown scopes where applicable — pick just the one you need.
