Ts-node-dev: Legacy watch mode

[pvtri96]

Hi @whitecolor,

I really love your project, it's awesome.

But I am running into a problem setting up ts-node-dev within a Docker container, which is using a mounted driver. In Nodemon documentation, they are having Legacy Watch mode that works very well in this case.

It would be nice if we also have something like this.

There's a pending pull request for that in node-dev repo:
https://github.com/fgnass/node-dev/pull/217

Look like it's abandoned, maybe it's time to split and fork it to not rely on a dead code? @whitecolor

Hi, I've checked the pending pull that @19majkel94 suggested and the solution appears to be the use of --poll as a ts-node parameter, so like this ts-node-dev --poll --respawn --transpileOnly src/app.ts.

@19majkel94 You can make the same pull request here (in lib/index.js), because ts-node-dev is already a fork of node-dev, not a wrapper, as you can see in the code.

I've opened the PR #58 here in ts-node-dev but it's still waiting for review and merge by @whitecolor 😕

I always used ts-node-dev --poll with docker on windows without any problem.

@whitecolor
If you like 30% CPU usage from polling every 100ms - yeah, it works without any problem.
I prefer 3s and 3% CPU usage, especially while working on a slower hardware like an old notebook.

[wclr]

Ok, merged and published it. May test.

[MichalLytek]

Looks like it's working and not consuming tons of CPU time 🎉 Thanks! 💪

@19majkel94
What params do you use to run?

[pvtri96]

I am using these params for my development process:

ts-node-dev --no-deps --respawn --poll --interval 1000 src/main.ts

The CPU usage is around 1-3% (this number will scale depending on how many files I have) which is a huge improvement 🚀.
