Deployment
Provider/store compatibility across Node servers, Node serverless, and edge runtimes (Vercel Edge, Cloudflare Workers), plus a custom-SessionStore recipe for edge-only persistence.
Full coverage — including runnable Vercel Edge / Cloudflare Worker examples — lives in docs/deployment.md in the repository.
Native-dependency stores don't run at the edge
SqliteSessionStore (native better-sqlite3 binding) and FileCheckpointStore/FileSessionStore (filesystem access) only work in Node runtimes. RedisSessionStore works anywhere that can reach your Redis instance over the network, including most edge runtimes.
