dagingaa / arrow-function-codemod.js

Created January 26, 2016 14:34

My preliminary stab at a proper codemod for appear.in that transforms anonymous functions to arrow functions.

	module.exports = (file, api, options) => {
	const j = api.jscodeshift;

	const root = j(file.source);

	const createArrowFunctionExpression = fn => {
	return j.arrowFunctionExpression(
	fn.params,
	fn.body,
	false);

dagingaa / arrow-parens.js

Created January 26, 2016 15:04

Fixes the arrow parens thing in eslint, but is slightly broken

	module.exports = (file, api, options) => {
	const j = api.jscodeshift;

	const root = j(file.source);

	const getBodyStatement = fn => {
	if (
	fn.body.type == 'BlockStatement' &&
	fn.body.body.length == 1
	) {

dagingaa / prototype-to-class.js

Last active December 23, 2022 11:38

Codemod to transform well-written function prototype style classes into the new ES2015 syntax. Requires jscodeshift.

	module.exports = (file, api, options) => {
	const j = api.jscodeshift;
	const root = j(file.source);

	// We have to add "use strict" for node to play nice
	// Taken from https://github.com/cpojer/js-codemod/blob/master/transforms/use-strict.js
	const hasStrictMode = body =>
	body.some(
	statement => j.match(statement, {
	type: 'ExpressionStatement',

dagingaa / refactor-functions-params-to-obj-destructuring.js

Created September 21, 2016 11:05

This is a non-working codemod that tried to refactor specific functions with multiple parameters into a single object with destructuring. It failed.

	export default function transformer(file, api) {
	const j = api.jscodeshift;

	const name = "subscribeToPlan";
	const newName = name;

	const root = j(file.source);
	root
	.find(j.MethodDefinition)
	.filter(path => !!path.value.key.name)
