Watching Multiple Paths

[FMCalisto]

Greetings,

I am trying to solve a particular issue regarding the use of your library. I need to watch two different paths. However, the watch library does not concern that (I think). For instance, if I do the following code, it will run it over and over. But, on the other hand, if I use one of the paths, it will run everything ok.

var filePath001 = path.resolve(rootPath, 'foo001', 'foo002');
var filePath002 = path.resolve(rootPath, 'foo003', 'foo004');

watch.watchTree(filePath001, function (f, curr, prev) {
  if (typeof f == "object" && prev === null && curr === null) {
    shell.exec('./scripts/run.sh');
  } else if (prev === null) {
    shell.exec('./scripts/run.sh');
  } else if (curr.nlink === 0) {
    shell.exec('./scripts/run.sh');
  } else {
    shell.exec('./scripts/run.sh');
  }
});

watch.watchTree(filePath002, function (f, curr, prev) {
  if (typeof f == "object" && prev === null && curr === null) {
    shell.exec('./scripts/run.sh');
  } else if (prev === null) {
    shell.exec('./scripts/run.sh');
  } else if (curr.nlink === 0) {
    shell.exec('./scripts/run.sh');
  } else {
    shell.exec('./scripts/run.sh');
  }
});

My question is, how can I have watching of several paths?

Thank you in advance. I would appreciate an answer.

@FMCalisto I don't think this is available by default.

I have the same concern and here is an example how someone could perform a watch on multiple directories.

// This file name is cssbundler.js
const path = require('path');
const watch = require('watch');

const targetListOfCss =  ['path/to/foo', 'path/to/bar'];
targetListOfCss.forEach(cssPath =>{
  let fullcsspath = path.resolve(cssPath);
  watch.createMonitor(fullcsspath, (monitor)=>{
    monitor.on('changed', (fp, curr, prev) =>{
      console.log('do stuff to bundle '+fp);
    });
});
});

from the cli node cssbundler.js

Dear @hyperking, thank you for your contribution. It seems a valid approach also.
