We’ve been considering this library at work for a performance sensitive application (real time game). Can anyone here speak to the performance and memory usage of QuickJS?
Here are some benchmarks: https://bellard.org/quickjs/bench.html

#12One quick improvement would be to have a Readme.

There is a readme on the project's main page: https://bellard.org/quickjs/
The newsworthy bit here is that the activity seemed to have stalled for year or two and now Fabrice pushed a few fixes and made a new release.

#14QuickJS is really cool! You can use it to embed JS code in a native binary, which is nice if you're trying to use a NodeJS library outside of the JS ecosystem. I put together a proof of concept for this about a year ago, in case this is a use case you currently have: https://github.com/ijustlovemath/jescx
stupid question but... doesn't Deno also promise that possibility? Or at least to compile a js app into a binary

Even if it does, it's always nice to have other options with different trade-offs

Performance is pretty good if you consider starting and running small scripts. There is an interesting feature of compiling a js file into a C array bytecode so your runtime code could load that directly skipping the parsing step.
For a long running orlarge JS code something like Spidermonkey or V8 with their JITs might be faster. But they are not as embedding friendly and their code bases are much larger.

#17I'm glad the project isn't dead-dead but still not a good sign it didn't get any love for 2+ years.
Re: New QuickJS Release
#18I just upgraded quickjs-emscripten - my JS-in-JS wrapper library - to this new version of the upstream quickjs.
If you want to safely evaluate untrusted Javascript in the browser or Node with control over CPU time and memory use, a custom module system, or call async code synchronously, check it out: https://github.com/justjake/quickjs-emscripten
It's used by a few projects like Hoppscotch, a Postman-like visual API client (https://hoppscotch.io/). They use it for request scripting: https://docs.hoppscotch.io/documentation/getting-started/res...

Yes, although the sizes of the binaries differ greatly. See this [1] Twitter reply. A "hello world" example produced an ~85mb binary in Node and Deno, whereas QuickJS produced a 6MB binary.
