Package Exports
- @babel/traverse
- @babel/traverse/lib/path
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 (@babel/traverse) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
@babel/traverse
@babel/traverse maintains the overall tree state, and is responsible for replacing, removing, and adding nodes.
Install
$ npm install --save @babel/traverseUsage
We can use it alongside Babylon to traverse and update nodes:
import * as babylon from "babylon";
import traverse from "@babel/traverse";
const code = `function square(n) {
return n * n;
}`;
const ast = babylon.parse(code);
traverse(ast, {
enter(path) {
if (path.isIdentifier({ name: "n" })) {
path.node.name = "x";
}
}
});
