hatchling v0.2.2

Hatchling

Buffered spawn for node.

Example

var spawn = require('hatchling'),
    timeout;

var child = spawn('ps', ['aux'], function(err, stdout) {
  console.log(stdout);
  clearTimeout(timeout);
});

timeout = setTimeout(child.kill, 1000); // kill it after a second if we dont hear back

// Example with invalid command options
spawn('ls', ['-aslkj'], function(err, stderr) {
  console.log(err);
  console.log(stderr);
});

Reasoning

Spawn is awesome but sometimes you need a quick way to just get the output and go. Hatcling lets you pass in as many or as few arguments as you want. The structure is:

spawn(cmd, [args], [options], [cb])

• cmd is a string of the command to execute
• args is an array of arguments passed
• opts is an option which is standard process.spawn options
• cb is a function that takes fn(err, stderr/stdout). If err is not null, stderr will be given. Otherwise it is stdout. If a process exits with a non-zero status code, an error will be thrown.
