// target file
function execute() { 
  var a = 'a'
}

// jscodeshift
export default(file, api) => {
  const j = api.jscodeshift
  const root = j(file.source)

  var node = root.find(j.VariableDeclaration)
  // i want to see what node looks like in javascript.

  return root.toSource()
}

可以推测搜索的内容是非空的集合：

class Offers(models.Model):
    business = models.ForeignKey(Business, related_name="business_offer",
                                 on_delete=models.CASCADE)
    title = models.CharField(max_length=255)
    subtext = models.CharField(max_length=255)
