Usage

var cn = require('cumulonimbus');
 
var template = new cn.Template();
var vpc = new cn.Ec2.Vpc("VPC");
vpc.enableDnsSupport(true);
vpc.enableDnsHostnames(true);
vpc.setCidrBlock("10.0.0.0/16");
vpc.setInstanceTenancy("dedicated");
vpc.addTag("Name", "VPC");
 
var publicSubnet = new cn.Ec2.Subnet("PublicSubnet");
publicSubnet.setCidrBlock("10.0.0.0/24");
publicSubnet.setVpcId(vpc);
 
template.addResource(vpc);
template.addResource(publicSubnet);
template.validate(function(err) {
  if (err === undefined) {
    console.log(JSON.stringify(template.toJson(), null, 4));
  }
});

Running the JavaScript file above yields the following output:
