For future reference, here is a way to use execvp() from node:
const ffi = require('ffi');
const ref = require('ref');
const ArrayType = require('ref-array');
const stringAry = ArrayType('string');
var current = ffi.Library(null,
{ execvp: ['int', ['string',
stringAry]],
dup2: ['int', ['int', 'int']]});
current.dup2(process.stdin._handle.fd, 0);
current.dup2(process.stdout._handle.fd, 1);
current.dup2(process.stderr._handle.fd, 2);
var ret = current.execvp("/usr/bin/program", ['progname', 'arg1, 'arg2',
arg3, ref.NULL]);
