OpenID Connect & OAuth2 Client

oidc-client is a comprehensive JavaScript client library for OpenID Connect (OIDC) and OAuth2, designed to facilitate secure authentication and authorization in web applications. It handles complex OAuth2 flows, including Authorization Code Flow with PKCE, implicit flow, and refresh token management, abstracting away much of the underlying protocol complexity. Developed by IdentityModel, it maintains a strong focus on security and adherence to OIDC/OAuth2 specifications. The current stable version is 1.11.5, with an active development cycle characterized by frequent bug fix releases and minor feature updates approximately every 1-2 months, as evidenced by recent patch versions. Key differentiators include its robust handling of session management, silent token renewal, and extensive configurability, making it suitable for a wide range of single-page applications and client-side integrations.
