simpatico VS esm.sh

>Does this mean that in theory i could skip the build/bundling step entirely?

You can but you must write your app in something the browser understands (js not ts, css not sass etc) and use native modules. For example, here is the test harness for a custom module, written in pure html with no build step: https://github.com/javajosh/simpatico/blob/master/combine2.h.... Here is a more complex (and much older) example from Crockford: https://www.jslint.com/

And yes, the experience developing this way is quite nice!

*>...use types [at] runtime..."

Two things. First, TS conceives of itself as having no runtime component. If it did, I think people (including the TS devs) would be more confused.

Second, I'd say rather we need a runtime type system. In fact I've tried my hand at writing one in the most minimalist way possible, and have been working on it recently [1]. The type system is explicit in that a type is a JSON like object, similar to JSON schema, but 100x less code.

[1] https://github.com/javajosh/simpatico/blob/master/friendly.h... This is effectively the test harness for the module.

Unpkg serves whatever is published to NPM, and if it's a library intended for the browser, that often includes minified versions ready for use in script tags, for example, https://unpkg.com/[email protected]/mithril.min.js. Sometimes the default export is CJS (which has require() calls), in which case, you can usually use the browse url that I mentioned to see if there's another export you can use.

https://esm.sh/ is definitely a good option too if you're OK with modules.

* Change my NPM imports to something that would work with Deno. The most straightforward thing to do was just change `import "foo"` to `import "npm:foo"`, but this felt hacky so eventually I used https://esm.sh, which worked for some packages but not others.

import { createClient } from "https://esm.sh/@supabase/supabase-js@2"; import { create, Payload } from "https://deno.land/x/[email protected]/mod.ts"; interface User { username: string; pin: string; } const supabase = createClient(Deno.env.get('SUPABASE_URL'), Deno.env.get('SUPABASE_SERVICE_ROLE_KEY')); const handler = async (req: Request): Promise => { if (req.method !== 'POST') { return new Response(null, { status: 405 }); } const { username, pin } = await req.json() as Vehicle; if (!username|| !pin) { return new Response(JSON.stringify({ error: 'username and PIN are required' }), { status: 400 }); } const { data, error } = await supabase .from('users') .select('*') .eq('username', username) .eq('pin', pin) .single(); if (error || !data) { return new Response(JSON.stringify({ valid: false }), { status: 401 }); } const jwtSecret = Deno.env.get('JWT_SECRET') as string;; const payload: Payload = { "username": username }; try { const token = await create({ alg: "HS256", typ: "JWT" }, payload, jwtSecret); // This line has the error console.log(token); return new Response(JSON.stringify({ token }), { status: 200 }); } catch (error) { console.error('Error creating JWT:', error); return new Response(JSON.stringify({ error: 'Error creating JWT' }), { status: 500 }); } }; Deno.serve(handler);

Easily serve libraries from local server/private VPS: You can try to serve and cache libraries by running esm.sh to improve loading times on your server side. Or to keep things simple, just upload a code to pastebin or similar services and directly use it here!
