I am looking for a tool or IDE that can help automatically refactor JavaScript or TypeScript function into a class.

It would be nice if it can take care of this keyword in a safe way but is not a requirement. I can also fix remaining issues manually afterwards.

The purpose I want to use it for, is easy migration/maintenance of a legacy code.



function MyService(dependency) {
    function privateMethod() {}

    function publicMethod() {
    return {


class MyService() {
    constructor(dependency) {}

    private privateMethod() {}

    public publicMethod() {
  • The only thing I have already found is something that can help me write it myself like jscodeshift

  • Other tools and libraries I found to help me write it from scrach in a worst case scenario: vscode-refactor-by-js and ts-morph library.

I googled your question and I found Visual Studio Code (you can see how to refactor here) - https://code.visualstudio.com/docs/editor/refactoring

Download link - https://code.visualstudio.com/

  • I use VSCode. Unfortunatelly it does not provide required refactoring method (to change a function into a class). Do you know any plugin supporting that?

  • @NinadKulkarmi The linka you provided navigates to the documentation of VSCode standard functionality. Unfortunately it does not meet my requirement. :(
