  • I have created a small anti-depression script
    4 projects | dev.to | 5 Mar 2024
    Install Node.js (or Bun, or Deno, or whatever JS runtime you prefer) if it's not there
  • Unison Cloud
    7 projects | news.ycombinator.com | 7 Feb 2024
    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).

  • Deno in 2023
    8 projects | news.ycombinator.com | 5 Feb 2024
    ~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.

  • Mini site for recommending songs using Svelte & Deno
    2 projects | dev.to | 3 Feb 2024
    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.
  • Supercharge your app with user extensions using Deno JavaScript runtime
    4 projects | dev.to | 24 Jan 2024
    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:
    4 projects | dev.to | 24 Jan 2024
    Protecting against memory-hungry scripts in Deno is more challenging. I won't go into details about how it works and instead direct you to the issue in the Deno repository with all the details. In short, you need to create a JavaScript runtime with a specific heap limit and add a callback that's invoked when the memory limits are approached. This gives you a chance to terminate the execution before Deno/V8 crashes the entire process.

    Thank you for the detailed feedback. Deno 1.38.4 was just released with a partial fix for the VSCode issue you mentioned. We're fixing the twisted issue too.

    15 projects | news.ycombinator.com | 29 Nov 2023
    This is being worked on: https://github.com/denoland/deno/issues/21122. Should be available with the next Deno release.

  • JSR: The JavaScript Registry

    Unpkg just serves the raw files, which may contain require() calls or import from other npm packages. That won’t work.

    The closest service is https://esm.sh, but you can’t download from it.

    9 projects | news.ycombinator.com | 1 Mar 2024
    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.

  • Deno Cron
    15 projects | news.ycombinator.com | 29 Nov 2023
    * 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.
  • Let's optimize dependency management with URL Imports
    3 projects | dev.to | 13 Oct 2023
    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!
