blueboat VS deploy_feedback

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?

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](https://github.com/losfair/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!

This sounds quite a bit like Cloudflare Workers, and they have a comparison page - https://github.com/losfair/blueboat/wiki/Comparison-with-Clo....

Blueboat may be what you’re looking for

> If one writes Go or Rust, there are much better ways to run them than targeting WASM

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: https://news.ycombinator.com/item?id=29112713).

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.

One of the valuable features of Solid Start is that you can use so-called "adapters" to completely change the output into something deployable basically everywhere that serves pages and with quite a lot of options: there are adapters for amazon web services, cloudflare pages and workers, deno deploy, netlify, standard node server (the default), vercel, and static deployment - the latter allows us to build something that we can put on github pages.

Developed using Fresh framework (https://fresh.deno.dev) and deployed to Deno Deploy (https://deno.com/deploy). For persistent storage I use a simple MySQL instance from DigitalOcean.

I've been really enjoying Deno for personal projects! The developer experience is excellent and Deno Deploy makes it easy to quickly & easily get things deployed.

I really liked the ease of https://fresh.deno.dev/ and https://deno.com/deploy. Just went through the getting started guide and it was basically 'run these two commands and log in here'. But I already know react, so if that's an issue maybe choose something else.

Like CDN, edge networks are supposed to be deployed at a large scale and shared among many tenants. This requires isolated execution contexts (so data can't leak between tenants) with a tiny footprint (so contexts can be frequently created and disposed of without hurting performance). NodeJS is too bloated to be a viable solution. Slimmer Javascript runtimes, like Next.js's edge runtime, Cloudflare's workerd, Deno deploy, and bun, are created to fulfill this specialized job.

Fresh really takes a fresh new approach to web dev. It is still quite new but the ecosystem is rapidly growing. Up until now the Deno ecosystem was a missing a full stack framework and Fresh seems to fill that void quite effectively. You can create scalable, performant applications with Fresh and Fauna quite easily. On top of that you can make fully serverless full stack applications on the edge when you deploy your Fresh app to Deno deploy, denoflare.dev or Netlify.

Deno Deploy with CockroachDB

Deno deploy enables the deployment of JavaScript, TypeScript, and WebAssembly code at the Edge. In fact, Supabase Functions and Netlify Edge are built with Deno. Also, Deno supports Azure functions.

Fresh is considered "The next-gen web framework", built for speed, reliability, and simplicity on Deno. It is an edge-first web framework that delivers zero JavaScript to the client by default with no build step. It is optimised for speed and, when hosted on the edge with Deno Deploy, can be fairly trivial to get a perfect Lighthouse page-speed score.

I'd say deno, because they've already established a proper ecosystem since day one, has a working usage such as Deno Deploy[0] and Fresh[1], and already addresses some issues about distribution issue on Node, while bun still acts like a replacement for Node.
