  • What's with All the Runtimes for JavaScript?
    2 projects | | 13 Aug 2022
    Right now it is an exciting time for JavaScript. We just got a new shiny fast runtime Bun, with the last new kid Deno being released only 4 years ago, and we have edge computing/serverless runtimes like Cloudflare worker and Blueboat. With all these hypes for the JavaScript community, I could not help but ask, how come only JavaScript gets all these fancy new runtimes? Why don’t we hear these more often in other languages?
  • Show HN: Distributed SQLite on FoundationDB
    5 projects | | 28 Jul 2022
    Hello HN! I'm building mvsqlite, a distributed variant of SQLite with MVCC transactions, that runs on FoundationDB. It is a drop-in replacement that just needs an `LD_PRELOAD` for existing applications using SQLite.

    I made this because [Blueboat]( needs a native SQL interface to persistent data. Apparently, just providing a transactional key-value store isn’t enough - it is more easy and efficient to build complex business logic on an SQL database, and it seems necessary to bring a self-hostable distributed SQL DB onto the platform. Since FoundationDB is Blueboat’s only stateful external dependency, I decided to build the SQL capabilities on top of it.

    At its core, mvsqlite’s storage engine, mvstore, is a multi-version page store built on FoundationDB. It addresses the duration and size limits (5 secs, 10 MB) of FDB transactions, by handling multi-versioning itself. Pages are fully versioned, so they are always snapshot-readable in the future. An SQLite transaction fetches the read version during `BEGIN TRANSACTION`, and this version is used as the per-page range scan upper bound in future page read requests.

    For writes, pages are first written to a content-addressed store keyed by the page's hash. At commit, hashes of each written page in the SQLite transaction is written to the page index in a single FDB transaction to preserve atomicity. With 8K pages and ~60B per key-value entry in the page index, each SQLite transaction can be as large as 1.3 GB (compared to FDB's native txn size limit of 10 MB).

    mvsqlite is not yet "production-ready", since it hasn’t received enough testing, and I may still have a few changes to make to the on-disk format. But please ask here if you have any questions!

    wasm has its place, especially for contained workloads that can be wrapped in its strict capability boundaries (think, file-encoding jobs that shouldn't access anything else but said files:

    wasmedge [0], atmo [1], krustlet [2], blueboat [3] and numerous other projects are turning up the heat [4]!

    They're not perfectly isolated to a high security standard such that you could deploy your own v8 workers SaaS. And they do have quirks and development woes. I haven't tested in production but if it's just your trusted apps wanting to exceed the cloudflare workers 30 scripts limit then both are wonderfully powerful solutions to put behind a https proxy.

  • Argbash – Bash Argument Parsing Code Generator
    6 projects | | 20 Mar 2023
    TypeScript is now tenable for bash scripts with the fast-starting Bun runtime

    Before Bun, Node+V8 was just too slow to start.

    IMHO all scripts should be written in get typechecking and all the rest of the editing experience. Plus things like Wallaby.js for live coding/testing.

  • Migrating from ts-node to Bun
    4 projects | | 19 Mar 2023
    I've wanted to take a look at some of the alternative JavaScript runtimes for a while. The thing that has held me back is npm compatibility. I want to be able to run my code in a runtime that isn't Node.js and still be able to use npm packages. I've been using ts-node for a long time now; it's what I reach for when I'm building any kind of console app. In this post I want to port a console app from ts-node to Bun and see how easy it is.

    I was a little weirded out by the inconsistent indentation in the output but I'm sure that's just a formatting issue. (I submitted a PR to fix this.) When I ran the suggested commands it looked like bun was happy and healthy.

    hey there! sounds like you're having some trouble with your merge sort visualization. i'm not super familiar with that specific issue, but have you heard of this cool package manager called Cotton? it's way faster and easier to use than NPM or Yarn, and i think it could really help you out with your web development using JavaScript. check it out here: anyways, have you tried using this library called Geschichte for managing query-parameters with hooks? it's super useful for state management and makes it way easier to manage state. you can find it here: be sure to leave a star on GitHub to support the creator! oh, and have you heard of this JavaScript runtime called Bun? it runs programs faster and installs packages automatically, and it's even better than Node.js! check it out here: hope this helps!
  • No one cares about Bun's speed. Your CI does though
    5 projects | | 5 Mar 2023
    I ported some tests from jest to bun recently and have been been pleasantly surprised -- it was pretty much a drop-in replacement and the speed difference is certainly noticeable.

    That said, it was a tiny and simple test set[1]. It may not be ready yet for more complex tests, as the docs warn[2]:
