Node sdout buffer size limits (stdout being truncated)

[yunusga]

Problem

If we have many templates, some times happens #3, !!! OUTPUT ERROR or Unexpected end of JSON input errors. This is child_process stdout being truncated.

Solution

If increase buffer size in lib/validator.js with option { maxBuffer: 1024 * 500 } all works.

// console.log(execPath.join(' '));
exec(execPath.join(' '), { maxBuffer: 1024 * 500 }, function (err, stdout, stderr) {
    let output = stdout;
    // ...

Proposal

Add option for setup maxBuffer if needed.
