Extism is an plug-in framework based on WebAssembly: https://extism.org/. - Source: Hacker News / 2 months ago

I started using WebAssembly in earnest a few months ago to make a backend auth library that works in several different languages[0]. It's built on Extism[1], which abstracts away some of the interfacing complexity. It's been an awesome experience. Frequently feels like magic. WASM is in an interesting place. The value has clearly been proved with a pretty minimal core spec. Now there's a big push to implement a... - Source: Hacker News / 6 months ago

Application plugins could also be wasm. That lets plugin authors write in any language they want and have their plugin work. That's the idea behind the Extism framework: https://extism.org/. - Source: Hacker News / 8 months ago

The WebAssembly component model is aimed at having composable components that can call each other. The components can be written in any language, compiled to WebAssembly, and interoperate: https://github.com/WebAssembly/component-model/ https://github.com/extism/extism A project to bring WebAssembly plugins to Godot: https://github.com/ashtonmeuser/godot-wasm Wasmer can be embedded in applications:... - Source: Hacker News / 9 months ago

This is exactly what we created Extism[0] and XTP[1] for! [0]: https://extism.org. - Source: Hacker News / 12 months ago

I see a few mentions of QuickJS, but they all refer to the fork of Bellard's QuickJS https://bellard.org/quickjs/, which I think deserves a mention. It seems to be still active (last release 2025-04-26, GitHub mirror at https://github.com/bellard/quickjs shows some activity). - Source: Hacker News / 2 months ago

This is a fantastic approach. BTW, it looks like the js engine is "QuickJS" [0]. (I'm not familiar with it myself.) I like it because sqlite by itself lacks a host language. (e.g., Oracle's plsql, Postgreses pgplsql, Sqlserver's t-sql, etc). That is: code that runs on compute that is local to your storage. That's a nice flexible design -- you can choose whatever language you want. But quite typically you... - Source: Hacker News / 4 months ago

And some lightweight alternatives like Bellard's QuickJS (https://bellard.org/quickjs/) in C and Kiesel (https://kiesel.dev/) in Zig. - Source: Hacker News / 8 months ago

Built on a highly optimized JavaScript runtime powered by QuickJS, Query offers fast startup times and efficient execution. Its built-in caching mechanism further enhances performance by storing function responses, reducing database load and latency. This focus on speed makes Query a standout choice for server-side rendering, especially in applications with many components. - Source: dev.to / 9 months ago

Which JS VMs have you tried embedding? People in this thread have suggested https://github.com/Moddable-OpenSource/moddable, and https://duktape.org/, but I haven't tried any of them. - Source: Hacker News / 9 months ago
