defnode v0.0.5

defnode

defnode is a node.js package that maps JavaScript Identifier AST nodes to/from their corresponding definition nodes. It is useful in tools that perform JavaScript source introspection.

For example, suppose we have the following code.

function a(b) {
  var c = 1, d;
}

defnode maps the following Identifier/definition pairs:

• a to/from the enclosing FunctionDeclaration node
• b to/from itself (since its Identifier node is its own declaration)
• c to/from its VariableDeclarator node
• d to/from its VariableDeclarator node

defnode uses marijnh/tern, but it should work with any SpiderMonkey API-compliant JavaScript AST.
