Small, fast, simple and streaming project scaffolder for myself, but not only. Supports hundreds of template engines through the @JSTransformers API or if you want custom `render` function passed through options

var buffer = require('buffer')
var isBuffer = require('../')
var test = require('tape')

test('is-buffer', function (t) {
  t.equal(isBuffer(new Buffer(4)), true, 'new Buffer(4)')
  t.equal(isBuffer(buffer.SlowBuffer(100)), true, 'SlowBuffer(100)')

  t.equal(isBuffer(undefined), false, 'undefined')
  t.equal(isBuffer(null), false, 'null')
  t.equal(isBuffer(''), false, 'empty string')
  t.equal(isBuffer(true), false, 'true')
  t.equal(isBuffer(false), false, 'false')
  t.equal(isBuffer(0), false, '0')
  t.equal(isBuffer(1), false, '1')
  t.equal(isBuffer(1.0), false, '1.0')
  t.equal(isBuffer('string'), false, 'string')
  t.equal(isBuffer({}), false, '{}')
  t.equal(isBuffer([]), false, '[]')
