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!

import { serve } from 'https://deno.land/[email protected]/http/server.ts'; import { WebClient } from 'https://deno.land/x/[email protected]/mod.js'; import { SupabaseClient } from 'https://esm.sh/@supabase/supabase-js@2'; const slack_bot_token = Deno.env.get("SLACK_TOKEN") ?? ""; const bot_client = new WebClient(slack_bot_token); const supabase_url = Deno.env.get("SUPABASE_URL") ?? ""; const service_role = Deno.env.get("SUPABASE_SERVICE_ROLE_KEY"); const supabase = new SupabaseClient(supabase_url, service_role); console.log(`Slack URL verification function up and running!`); serve(async (req) => { try { const req_body = await req.json(); console.log(JSON.stringify(req_body, null, 2)); const { token, challenge, type, event } = req_body; if (type == 'url_verification') { return new Response(JSON.stringify({ challenge }), { headers: { 'Content-Type': 'application/json' }, status: 200, }); } else if (event.type == 'app_mention') { const { user, text, channel, ts } = event; const url_path = text.toLowerCase() .includes('code') ? '/code' : '/general'; const { error } = await supabase.from('job_queue').insert({ http_verb: 'POST', payload: { user, text, channel, ts }, url_path: url_path }); if (error) { console.error(error); return new Response(JSON.stringify({ error: error.message }), { headers: { 'Content-Type': 'application/json' }, status: 400, }); } await post(channel, ts, `Taking a look and will get back to you shortly!`); return new Response('', { status: 200 }); } } catch (error) { return new Response(JSON.stringify({ error: error.message }), { headers: { 'Content-Type': 'application/json' }, status: 400, }); } }); async function post(channel: string, thread_ts: string, message: string): Promise { try { const result = await bot_client.chat.postMessage({ channel: channel, thread_ts: thread_ts, text: message, }); console.info(result); } catch (e) { console.error(`Error posting message: ${e}`); } }

It has a decent compatibility with both Jest and Vitest's APIs (you can track progress here so you can use it as almost a drop-in replacement for either. Just as Node's, it has describe/it, mock, test and others, but with the expect syntax (which I find more readable). For example:

In this third and final article in the series on HTML Streaming, we will explore the practical implementation of the Diff DOM Streaming library in web browsing. This approach will allow any website using web components to retain its state during browsing. We will discuss in detail how to achieve this step by step using VanillaJS and Bun.

At Node Conference 2023, Jarred Sumner (creator of Bun) showed a demo of server components in Bun, so there is at least partial support in that ecosystem. The Bun repo provides bun-plugin-server-components as the official plugin for server components. And while I haven’t looked at it in-depth, Marz claims to be a “React Server Components Framework for Bun”.

Continuously evolving, Bun is currently optimized for MacOS and Linux, with ongoing efforts towards Windows compatibility. Tailored for resource-constrained environments like serverless functions, it emerges as an ideal solution. The Bun team is committed to achieving comprehensive Node.js compatibility and seamless integration with prevalent frameworks. For those intrigued by Bun's potential and want to give it a try, more information is available on its website at https://bun.sh/.

Let’s say you are interested in learning more about Bun and probably give it a try. Bun has a website, where you can learn more about Bun and its features (including all the benchmark data captured in this issue), and here is the link.

Looks like it, it seems the 2% are mostly odd platform specific issues that the authors' did not deem very important (my assumption for the release happening anyway). AFAIK this[1] PR tries to fix them.

Bun has a solution for it. First of all, it already has a list of trusted dependencies. For them, Bun will execute all necessary scripts by default. Otherwise, you can add it to trustedDependecies in your package.json file. In Bun community usage of trustedDependencies is a hot topic. There are several suggestions on how to improve it.

Install Node.js (or Bun, or Deno, or whatever JS runtime you prefer) if it's not there

I think maybe I was unclear. I'm talking about writing libraries that abstract across these differences and provide a single API, as sibling describes. I already know it's possible. I made a simple filesystem abstraction here[0] and a very simple HTTP library that uses it here[1]. They both work in Node/Deno and the browser. Unfortunately I ran into issues with Bun's slice implementation[2]. But I suspect there's a much better way of detecting and using the different backends.
