List running applications using NodeJS

Question

Using NodeJS I want to get a list of open applications on Windows.

Something along the lines of:

exec("tasklist", function (error, stdout, stderr) {

    for(var i=0;i<stdout.length;i++)
    {
        if( stdout[i]['name'].indexOf('ll_') > -1 )
        {
            appList.push({'id':stdout[i]['id'],'name':stdout[i]['name']});
        }
    }

});

Where appList is an object of running applications with their ID and Name if they start with ll_.

How can I do this?

Answer 1

(I don't run Windows, so the following is untested)

First, install tasklist:

$ npm install tasklist

Then, use the following script:

var tasklist = require('tasklist');

tasklist(function(err, tasks) {
  if (err) throw err; // TODO: proper error handling
  var appList = tasks.filter(function(task) {
    return task.imageName.indexOf('ll_') === 0;
  }).map(function(task) {
    return {
      id   : task.pid, // XXX: is that the same as your `id`?
      name : task.imageName,
    };
  });
});
