Question

As per this question:

node.js image compression

I’m trying to run pulverizer in node.js, in code.

How do I use command line commands inside node.js?

Thanks.

Answer 1

Pulverizr is a node module like any other, so once you have it installed, you ‘require’ the module as usual. The command line part, cli.js, isn’t special. All it does is parse command line arguments, and then ‘require’ the standard module file and call the ‘compress’ method.

var pulverizr = require('pulverizr');
var options = {
  dry: false,       // dryrun test  
  quiet: false,     // force quiet run
  recursive: false, // Run recursively
  verbose: false    // Run verbosely
};
var inputs = [ 'somefilename.jpeg', 'secondfilename.png' ];

var job = pulverizr.compress(inputs, options);

I don’t know beyond that, you’ll have to check it out. And ‘options’ are optional.
