nodejs下监听文件更改的插件

  var path = require(‘path‘)
  var Chokidar = require(‘chokidar‘);
  var watcher = Chokidar.watch([path.join(__dirname, ‘../src‘)], 
    // ignored: /(^|[\/\\])\../, 
    persistent: true,
    usePolling: true,
  );
  var log = console.dir.bind(console);
  var watchAction = function(event, eventPath)
    log(`Has been $evented, file: $eventPath`);
    // 这里进行文件更改后的操作
  
  watcher
  .on(‘ready‘, () => log(`Initial scan complete. Ready for changes.`))
  .on(‘add‘, path => log(`File $path has been added`))
  .on(‘change‘, path => watchAction(event: ‘change‘, eventPath: path))
  .on(‘unlink‘, path => watchAction(event: ‘remove‘, eventPath: path));
