Does node-runner use the same node instance?

[aspirisen]

Hello, I am interested if node-runner reuse the node instance between functions run?

# node is running and waiting for input?
runner = NodeRunner.new(
  <<~JAVASCRIPT
    const hello = (response) => {
      return `Hello? ${response}`
    }
  JAVASCRIPT
)

And do not bootstrap node on every function call

# These functions call do not launch node every time
runner.hello "Goodbye!"
runner.hello "Goodbye! 2"

@aspirisen There's no persistent process, it's a single execution to get the response back.

@jaredcwhite that mens that every time I call a function on runner - then new nodejs process has to bootstrap again, I think that can have affect performance.

Would you consider such new feature?

@aspirisen So the persistent side process concept was a feature of https://github.com/bridgetownrb/bridgetown-lit-renderer, so I have a bit of an idea how it could work. I don't have any time to work on this for the time being, but if you want to work on something (and maybe that Lit plugin can help) for a PR, happy to review!
