Package Exports

dash-ast

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (dash-ast) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

dash-ast

walk an AST, quickly

Install

npm install dash-ast

Usage

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.
