OpenID Connect & OAuth2 Client (TypeScript)

oidc-client-ts is an actively maintained TypeScript library, currently at version 3.5.0, providing OpenID Connect (OIDC) and OAuth2 protocol support for client-side, browser-based JavaScript applications. It includes robust features for user session and access token management. This project is a direct fork of the unmaintained `IdentityModel/oidc-client-js`, ported to TypeScript with a largely similar API for its 2.0 release. Moving forward, it prioritizes OAuth 2.1 protocols and explicitly *does not* support the deprecated implicit grant. A key change since v3.x is the transition from `crypto-js` to the browser's native `crypto.subtle` module for cryptographic operations, which mandates the use of secure contexts (HTTPS). The library supports various flows, including Authorization Code Grant with PKCE, Authorization Code Grant, Resource Owner Password Credentials (ROPC) Grant, Refresh Token Grant, and Silent Refresh Token in iframe Flow.
