imports-visitor/dist/index.js

Babel visitor that makes it easier to work with imports and require calls.

"use strict";

var ImportDefinition = require("./ImportDefinition");

// Gathers all imports and requires and pushes them into the `this.imports`
// array passed via the second argument to traverse.
// Example usage:
// visitor: {
//   Program(path) {
//     const imports = [];
//     path.traverse(importsVisitor, { imports });
//     console.log(imports);
//   },
// },
