Does Authava support Deno?

Yes — @authava/client works seamlessly with Deno. It’s written in TypeScript and built with full ESM compatibility, so you can import it directly without needing any bundlers or compatibility hacks.

Here’s a real-world example of how we use Authava in a Deno app to handle cookie-based session validation:

import { AuthavaClient, AuthavaSession, AuthavaUser } from "@authava/client"

const sessionCache = new Map<
  string,
  { session: Partial<AuthavaSession>; expiresAt: number }
>()

export const authMiddleware = async (ctx: any, next: () => Promise<unknown>) => {
  const cookie = ctx.request.headers.get("cookie")

  if (!cookie) {
    ctx.response.status = 401
    ctx.response.body = { error: "Unauthorized: No authentication provided" }
    return
  }

  const cached = sessionCache.get(cookie)
  if (cached?.expiresAt > Date.now()) {
    ctx.state.user = cached.session.user
    ctx.state.session = cached.session
    return await ensureUserExists(ctx, next)
  }

  const session = await ctx.state.authava.getSession({ Cookie: cookie })

  if (!session) {
    ctx.response.status = 401
    ctx.response.body = { error: "Unauthorized: Invalid session" }
    return
  }

  sessionCache.set(cookie, {
    session,
    expiresAt: Date.now() + 300_000, // cache for 5 minutes
  })

  ctx.state.user = session.user
  ctx.state.session = session
  return await ensureUserExists(ctx, next)
}

🔐 Authava works great in Deno-based APIs and web services. You can validate sessions using standard Cookie headers and cache results to improve performance across your middleware.
