Fixed unreliable hot reloading

[tungv]

1. remove cwd option to yield absolute paths
2. add debounce to avoid multiple restarts happen unexpectedly when more than one file change

[leo]

Looks really good! But how about using a package for the debouncing? The function looks like it could be abstracted away with a package.

[tungv]

I initially used lodash, but worried about the size of the package. What do you think about lodash/debounce?

[leo]

@tungv I'd rather go with a package that's only doing debouncing, nothing else.

[tungv]

Ok Leo, I will update in a few hours. Thanks!

[tungv]

hi @leo, I opted to use debounce npm package.

their code looks very clean https://unpkg.com/debounce@1.0.2

[leo]

Thanks a lot!

[tungv]

Great. Thank you for merging this over the weekend. I'm eager to use the new version next week.

It seems like this merge makes the --ignore option no longer work properly, reverting #24

[tungv]

it's true. --ignore with relative paths is broken. How about resolving ignored paths before passing them to chokidar?

[bakpakin]

That requires detecting if a pattern is resolvable. Patterns like **/tmp/** are valid, but should not be resolved with path.resolve. Essentially, chokidar ignores anymatch patterns, not directories.

[tungv]

maybe we should explicitly say that ignore pattern are not relative to cwd.

Interestingly, this doesn't fix hot reloading issue for me. Still same thing as described in #23 :/
