Spawning process with arguments in node.js

Question

I need to spawn a child process from node.js, whilst using ulimit to keep it from using to much memory.

Following the docs, it wasn\'t hard

Answer 1

Those are two different commands. Don't club them if you are using spawn. Use separate child processes.

 child1 = spawn('ulimit', ['-m', '65536']);
 child2 = spawn('coffee', ['app.coffee']);

If you are not interested in output stream(if you want just buffered output) you can use exec.

var exec = require('child_process').exec,
child;

child = exec('ulimit -m 65536; coffee app.coffee',
  function (error, stdout, stderr) {
    console.log('stdout: ' + stdout);
  }
});
