Reusable interpreters by save/restore state
pauleveritt opened this issue · comments
As background, I have a long tutorial about test-first development for browser-Python with Vitest. It has a section on speeding up test runs to use one interpreter instance for all tests.
I'm interested in writing a variation of that tutorial, using cowasm. Does it have a story for resetting an interpreter to a known, saved state in NodeJS?
As an aside, can you have multiple interpreters, in Node and/or browser?

Not really. I could potentially see how to implement that if the state is a "waiting for input from the user" state, but it's certainly not implemented.

Yes, definitely, that works very well. Each has their own isolated state in a Worker thread, and they can run in parallel. This does work in pretty much the same way in both node and the browser.
Thanks for the fast response. I wonder if I could get faster testing with a pool of pre-warmed interpreters.
I'll go ahead and close this.
