Transcrypt VS deno

This is the primary difference between Pyodide and projects like Transcrypt or Brython: rather than transpiling to JavaScript, you get the real-deal CPython interpreter running client-side in the user's browser. There are a few things that don't work out of the box, since CPython usually runs on a computer and the Browser environment has some unique restrictions (lack of low-level access to networking, for one), but most things do just work.

In the past, I've personally used GWT to transpile Java to JavaScript in order to share some complex code modules that we needed to use on both the server and client for an enterprise application. In more recent years, I've been using Transcrypt to develop React/MUI applications that are coded in Python. So I'm able to use JS libraries that are proven to work great in a web browser, but use my preferred language to code to the API of those libraries. This approach is certainly not for everyone, but it can be a viable option in some cases.

I now use Python everywhere. Desktop (PySide), embedded (MicroPython), web dev (React via Transcrypt), mobile (Kivy), and just general scripting. I love the versatility of Python, the ease of reading it without the visual cruft of other languages, and the availability of existing libraries that do just about everything you can think of. I also agree with the OP on the welcoming attitude of the Python community. The fact that Python is used in so many different areas leads to many new learning experiences when talking to other Python developers.

Transcrypt is pretty usable for this.

Transcrypt transpiles Python into JavaScript in the same way that TypeScript gets transpiled into JavaScript. It lets Python code word with JavaScript libraries that can then be run in a web browser.

There are options for writing Python and transpiling it into JavaScript but, frankly, they suck (https://www.transcrypt.org/).

Lol, I'll tell you but you're not gonna like it - I write React applications in Python using a Python-to-JS transpiler called Transcrypt, and the source needs to be valid lintable Python code, so no JSX.

The Python AST module exists for this purpose and works by tokenizing individual pieces of the source code. It's also how transpilers such as Transcrypt work their magic to convert Python code to other languages.

NodeJS is the dominant Javascript server runtime environment for Javascript and Typescript (sort of) projects. But over the years, we have seen several attempts to build alternative runtime environments such as Deno and Bun, today’s subject, among others.

https://github.com/denoland/deno/issues is the ideal place -- we try to triage all incoming issues, the more specific the repro the easier it is to address but we will take a look at everything that comes in.

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

QUIC is very exciting, after seeing what it can do for performance in Cloudflare network and Cloudflare workers, I can't wait to finally see it in Deno[0] 1.41.

So as an end user it's kind of like https://deno.com/ where you buy into a runtime + comes prepacked with DBs (k/v stores), scheduling, and deploy stuff?

> by storing Unison code in a database, keyed by the hash of that code, we gain a perfect incremental compilation cache which is shared among all developers of a project. This is an absolutely WILD feature, but it's fantastic and hard to go back once you've experienced it. I am basically never waiting around for my code to compile - once code has been parsed and typechecked once, by anyone, it's not touched again until it's changed.

Interesting. Whats it like upgrading and managing dependencies in that code? I'd assume it gets more complex when it's not just the Union system but 3rd party plugins (stuff interacting with the OS or other libs).

~90MB+ at this stage and do now allow compression without erroring out. Deploying ala Golang is not feasible at that level but could well be down the line if this dev branch is picked up again!

The exe output grew from from ~50MB to plus ~90MB from 2021 to 2024: https://github.com/denoland/deno/discussions/9811 which mean Deno is worse than Node.js's pkg solution by a decent margin.

Behind the scenes is a simple Sveltekit-powered server function to fetch a Spotify client token then find a user's recommendation playlist and its track information. A Deno edge function to performs this data fetch and renders server-side Svelte.

If your application is written in JavaScript, integrating it with JavaScript extensions is a no-brainer. However, Secutils.dev is entirely written in Rust. How would I even begin? Fortunately, I recently came across an excellent blog post series explaining how to implement your JavaScript runtime in a Rust application with Deno:
