Oslo is a zero-dependency TypeScript collection of auth-related utilities covering JWTs, OAuth2, password hashing, OTP, WebAuthn, cookies, encoding, and CSRF protection. It is runtime-agnostic (Node.js, Deno, Bun, Cloudflare Workers) but has been deprecated in favor of packages published under the Oslo project.
Use cases
- create and verify JWTs in a TypeScript app
- implement OAuth2 client flows
- hash and verify passwords
- add TOTP two-factor authentication
- verify WebAuthn passkey assertions
- parse and serialize cookies
- generate cryptographically strong random values
- add CSRF protection to requests
When to choose
- you need lightweight, runtime-agnostic auth primitives without pulling a full auth framework
- you are building custom auth on edge runtimes like Cloudflare Workers or Deno
- you want typed, zero-dependency crypto, JWT, or WebAuthn helpers
When to avoid
- starting a new project, since the package is deprecated in favor of the split Oslo project packages
- you want a batteries-included auth solution with sessions and user management
- you need support for Node.js 16/18 without polyfilling Web Crypto
