Deno Standard Library is a collection of high-quality APIs for Deno and the web.
The standard library provides foundational modules and utilities designed to work with Deno's runtime and web standards. It offers a curated set of packages covering common programming tasks, allowing developers to build applications without relying on external dependencies for basic functionality. The library is organized into distinct packages, each addressing specific domains of functionality.
Developers should choose this library when building Deno applications that need reliable, well-maintained standard utilities. It suits projects of any scale that want to minimize external dependencies while maintaining code quality and consistency with Deno's design philosophy. The library is particularly valuable for those committed to the Deno ecosystem who want APIs designed specifically for that runtime rather than adapted from Node.js conventions.
The project maintains semantic versioning for packages at version 1.0.0 and above, providing stability guarantees for production use. Development is organized around an architecture guide and design documentation that explain the library's structure and decision-making principles. The project has established contributing guidelines and maintains a frequently asked questions resource to support community participation. Package distribution has migrated to JSR, with older versions remaining available through the previous hosting location.
