Deno Standard Library

The Deno Standard Library is a collection of audited TypeScript modules maintained by the Deno core team and published on JSR under the @std scope. It provides common utilities including HTTP server helpers, path manipulation, assertions, CSV and JSON parsing, hashing, encoding, streams, date formatting, and more. All modules are guaranteed to work with the current stable Deno release and do not rely on third-party dependencies.
