Grant Koa OAuth Proxy Middleware

grant-koa is a specialized middleware designed to integrate the Grant OAuth Proxy into Koa.js applications. It abstracts the complexities of OAuth and OpenID Connect flows, providing a unified interface for authenticating users against various identity providers (e.g., Google, GitHub, Facebook). The current stable version is 5.4.8. As an adapter for the core `grant` library, its release cadence is generally tied to updates in `grant` and compatibility with major Koa versions. This package is crucial for Koa developers needing to implement robust and flexible authentication/authorization without deep diving into each OAuth provider's specific API, offering a streamlined approach to secure user access and data.
