awesome-tagged-templates VS esm.sh

When zx first appeared, it was a tiny esm script that just proposed a new idea for how child_process.spawn API could be enhanced with string template literals.

The template combines HTML and JavaScript. To understand this approach, consider how PHP pages are generated. In PHP, code is embedded within the HTML. Similarly, this library leverages JavaScript template literals to achieve the same objective. From the definition: "Template literals are literals delimited with backtick (`) characters, allowing for multi-line strings, string interpolation with embedded expressions, and special constructs called tagged templates".

The numbers we are printing are monetary values so they are missing a decimal value and a currency symbol. One way we can do this is by using JavaScript template literals to append and prepend the pieces we are missing.

Tagged templates[0], the language feature that enables this, were introduced in ECMAScript 2015 apparently – arguably at least somewhat new in the lifespan of JavaScript. :)

Java is getting a similar feature with template processors[1]. It would be nice to have it in Python as well – i.e. not just f-strings, but something that (like tagged templates) allows a template function process the interpolated values to properly encode them for whatever language is appropriate (e.g. shell, SQL, HTML, etc.).

References: Template literals (Template strings)

We are using a string template literal to create the tag and the ${} syntax to provide string interpolation, that is, substituting the values of href and altText into our string.

In TypeScript, a string literal type is a type that represents a specific set of string values. For example, the type "red" | "green" | "blue" represents the set of three string values "red", "green", and "blue". Template literal types allow you to perform operations on these string literal types using the same syntax as template literal strings in JavaScript.

The example also showcases the use of inline templates, employing JavaScript Template Literals. The JSON data obtained from the GET request is accessible through the "data" variable.

These are called "tagged templates": https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

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!

""; 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') ?
