The official Deno Standard Library, a collection of high-quality TypeScript packages published on JSR covering assertions, async utilities, collections, CLI parsing, caching, serialization, and more. Packages are designed for Deno but many also work with Node.js, Bun, browsers, and Cloudflare Workers.

Use cases

• parse command line arguments in a deno script
• assert deep equality in tests
• add an LRU or TTL cache in javascript
• read and write CSV files in deno
• debounce, retry, or pool async operations
• chunk, group, or deduplicate arrays with pure functions
• encode and decode CBOR data

When to choose

• you're building Deno applications and want well-maintained, officially supported utilities
• you need tested, dependency-free building blocks that also run on Node, Bun, or browsers
• you want semver-stable packages with generated docs on JSR

When to avoid

• you need a single bundled library rather than many small per-feature packages
• you rely on packages still marked UNSTABLE (e.g. cache, cbor, datetime) for production-critical code
• your project is not in the JavaScript/TypeScript ecosystem
