  • Rebuilding Web Application - What tech to use?
    1 project | | 20 May 2022
    There's a lot of momentum in the TypeScript community, but not just for NodeJS. Deno has a bright future ahead of it, and imo it's easier to use than Node when working on fresh TypeScript projects.
  • Is TypeScript inevitable future of webdev or will it die out some day?
    3 projects | | 13 May 2022
    Given that there is a proposal for adding static typing to JavaScript, based off the State of JS survey, and the fact that Deno has been released with first-class TypeScript support, I'd say it's not going anywhere soon.

    > My understanding is that packages are not sandboxed, but your entire Deno process is. Meaning that if one part of my app requires full read/write access then any package included in my app also gets it. Is that correct?

    Yes. There has been a discussion on per dependency permissions several times but the conclusions is that it would be difficult to implement and get right semantically. See

  • Ecosystem and Frameworks: My Role at Netlify
    8 projects | | 11 May 2022
    I bring this up because I get to continue to work in open source in my role at Netlify. Edge functions use the amazing Deno project, a modern open-source runtime for JavaScript and Typescript.

    You might want to consider adding Deno [1] to the language examples:

    Deno can compile to wasm, so it can plug in through that vertical. But it's just TS on the frontend.

    I'm mainly a python person, but Deno's been the most alluring development in the JS ecosystem since typescript for me. Might be helpful to you all to capture some steam from source.

    2 projects | | 28 Apr 2022
    To answer the first question "learn JS or TS" the answer has to be JS then TS. Nowadays to become a professional web application developer you need both. You first need a firm foundation in JS before adopting TS. After all, the web browser and Node do not understand TS (unlike Deno). When debugging code, you might have access to source maps that link the obfuscated JS code to the TS instructions but sometimes to need to delve deep into the JS and get as close to the JS processor as possible to discover the root cause of issues.
  • We're all living on it. But what exactly is The Edge?
    3 projects | | 27 Apr 2022
    Edge Functions are very much like serverless functions. You can write them using JavaScript or TypeScript, but instead of using Node.js under the hood, they are powered by Deno — an open source runtime built on web standards. With Netlify Edge Functions, you can transform HTTP Requests and Responses, stream server rendered content, and even run full server side rendered applications at The Edge!
