How to convert to a `NodePath`? about jscodeshift

[fkling]

Recast (ast-types actually) provides two APIs: One lets you access the underlying "raw" AST node, with .value or .node, as you already know. The other gives you a NodePath instead of the raw AST node value.

Examples:

var args = path.value.arguments; // array of AST nodes
var args = path.get('arguments'); // NodePath representing the array of AST nodes

.get takes multiple arguments. To get the NodePath to the first AST node in arguments, you can do:

var pathToFirstArg = path.get('arguments', 0); // or args.get(0) from above

See also https://github.com/benjamn/ast-types#nodepath .

Wrapping the element with j() gives me ...

j will always return a collection of NodePaths.

Perfect. Thanks, that helped me get there.

Do you have any thoughts as to where I should put this codemod transform? I'm either going to start a repo myself or open a PR to a pre-existing collection of transforms. Do you have any opinions on where it should go?

I imagine there is a lot of value for people who start without Babel/JSX and want to convert their codebase later to use JSX.

Feel free to create your own repo or send a PR to https://github.com/cpojer/js-codemod which I have used as a collection of useful codemods that I ran at FB.

@cpojer: What about https://github.com/reactjs/react-codemod ? Is that more for API changes between versions?

Oh yeah, react-codemod is fine for React specific codemods.
