    var dashAst = require('dash-ast')
    var isIdentifier = require('estree-is-identifier')
     
    var deps = []
    dashAst(ast, function (node, parent) {
      if (node.type === 'CallExpression' && isIdentifier(node.callee, 'require')) {
        deps.push(node.arguments[0])
      }
    })

    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.

    dashAst.withParent(ast, callback)

    Call callback(node) on each node in ast. This does a preorder traversal, i.e. callback receives child nodes after the parent node. Each node has an additional property node.parent referring to the parent node.

    dashAst.withParent(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. Each node has an additional property node.parent referring to the parent node.
