watch or auto build option about rebel

[chenglou]

Jenga has a watcher, but it's currently linux-only. I guess you could set up your own watcher for now?

I've set up my own watcher for now, I'll close this issue.

@IwanKaramazow - What worked well for you?

[IwanKaramazow]

@jordwalke : node watch + webpack for hmr & js modules in the browser

// watch.js
const { exec } = require('child_process');
const sane = require('sane'); //wrapper around fs.watch

const src = `${__dirname}/src`;
const compile_command = 'node ./node_modules/.bin/run';

const watcher = sane(src);

watcher.on('change', (filepath, root, stat) => {
    exec(compile_command, (err, stdout, stderr) => {
      if (err) {
        console.error(err);
        return;
      }
      console.log(stdout);
    });
 });

It does the job...
