auth_middleware
@pomdtr
Authentication middleware Guards your public http vals behind a login page. This val use a json web token stored as an http-only cookie to persist authentication. Usage Set an AUTH_SECRET_KEY env variable (used to sign/verify jwt tokens) to a random string . Then use an API token to authenticate. import { auth } from "https://esm.town/v/pomdtr/auth_middleware"; async function handler(req: Request): Promise<Response> { return new Response("You are authenticated!"); } export default auth(handler); See @pomdtr/test_auth for an example ⚠️ Make sure to only provides your api token to vals you trust (i.e. your own), as it gives access to your whole account.

blob_admin
@stevekrouse1
Blob Admin This is a lightweight Blob Admin interface to view and debug your Blob data. Versions 0-17 of this val were done with Hono and server-rendering. Versions 18+ were generated with Townie and use client-side React. To use this val, fork it to your account. Authentication is handled by @stevekrouse/lastlogin, so only the owner of the val will be able to see and edit their own blobs.

WIP Searcher for HN whos hiring posts HonoJs doesn't support render for async components so the style is off for the home page. And the state changes don't register in html rendering so thinking of using react instead.
