WasmEdge is already one of the smallest and most efficient Wasm runtimes out there. It embeds into libsql (SQLite on the server!) to execute user definited functions to perform complex tasks like HTTPS web services & AI inference from SQL statements! https://wasmedge.org/docs/embed/use-case/libsql/

The WasmEdge C++ and Rust SDKs allow host applications to embed Wasm functions asynchronously. It is critically important in many applications where the embedded Wasm function is simply not allowed to block the execution of the host applications. https://github.com/second-state/wasmedge-rustsdk-examples/bl...

Asynchronous host SDKs are complex and a lot of work still remains. We are continuously improving it with our end user and partner communities.

What's coming next?

* Support plugins in our Docker and k8s integrations

The example below, from the microservice-rust-mysql demo app, shows how to create a web server in hyper for WasmEdge. The main listening loop of the web server is as follows:

> forcing SQLite

It might be the case that it's running SQLite via wasm. If so, then other database engines would need to be runnable in a browser too.

PostgreSQL has been shown to work in the browser (eg https://www.crunchydata.com/blog/learn-postgres-at-the-playg..., and also https://github.com/snaplet/postgres-wasm), so that might be an option.

Not sure about others.

Thanks, I've been looking at WASM, for ex https://github.com/snaplet/postgres-wasm/tree/main/packages/... , it would certainly simplify everything to "download a fat file".

Hey! Peter from Snaplet here. This is really exciting stuff. We created the OSS postgres-wasm (https://github.com/snaplet/postgres-wasm) example a few weeks ago. An idea I'm playing around with is something like:

  1. Visit https://postgresql.com/try?version=14.x

Other in-memory alternatives for PostgreSQL embedded-postgres (I haven't tried it yet) postgres-wasm (currently it only runs in the browser).

"/s" is obsolete as of now: https://github.com/snaplet/postgres-wasm I'm so sorry

Today we're open sourcing postgres-wasm with our friends at Snaplet.

Peter from Snaplet here. A month ago I saw the CrunchyData post and wanted to play around with the code that made it happen, it wasn't OSS so I asked for help:

> If anyone out there wants to work on an open source version of this full-time please reach out to me. [0]

Paul reached out and we started working on it almost immediately. Check out the repo here: https://github.com/snaplet/postgres-wasm

We have a blog post about some of the interesting technical challenges that we faced whilst building this: https://www.snaplet.dev/post/postgresql-in-the-browser

Like most things, this is built on-top of the amazing open-source projects that made this possible, but special mention goes to v86.js and buildroot. We just glued it together.
