dashAst(ast, function (node, parent) {
  if (node.type === 'CallExpression' && isIdentifier(node.callee, 'require')) {

API

dashAst(ast, callback)

Call callback(node, parent) on each node in ast. This does a preorder traversal, i.e. callback receives child nodes after the parent node.

dashAst(ast, { enter, leave })

Call enter(node, parent) on each node in ast before traversing its children, and call leave(enter, parent) on each node after traversing its children. If a node does not have children, enter() and leave() are called immediately after each other.
