Shiftpack – Automated React Library Migrations

Shiftpack

Shiftpack is an open-source npm package that helps developers migrate React ecosystem libraries between versions with minimal manual work.
It is powered by jscodeshift and comes with pre-built codemods for popular libraries like React Router, Redux, and Material UI.

Why Shiftpack?

Upgrading major versions in React projects often requires large, error-prone manual changes —
for example, migrating from React Router v5 → v6, moving from classic Redux → Redux Toolkit, or upgrading Material UI v4 → v5.
Shiftpack makes this process easier by:

Installation

npm install -g shiftpack

Or use npx directly:

npx shiftpack migrate react/v5-to-v6 --path src/

Usage

You can run a single migration or apply an entire migration collection:

shiftpack migrate react/v5-to-v6/useEffectMigration --path src/

This command scans your src/ folder and automatically updates matching code patterns.

Example

Before migration (React Router v5):

import { useRouteMatch } from "react-router-dom";
 
const Profile = () => {
  const match = useRouteMatch();
  return <Link to={`${match.url}/settings`}>Settings</Link>;
};
 
<p className="my-page-content">After migration (React Router v6):</p>
 
import { useResolvedPath } from "react-router-dom";
 
const Profile = () => {
  const match = useResolvedPath("");
  return <Link to={`${match.pathname}/settings`}>Settings</Link>;
};
 
<h2 className="my-section-title">Roadmap</h2> 
<ul className="list-disc list-inside my-page-content pl-4"> 
    <li>Expand React Router v5 → v6 codemods</li> 
    <li>Redux and Redux Toolkit migrations</li> 
    <li>Material UI v4 → v5 support</li> 
    <li>Future support for Vue ecosystem</li> 
    <li>CLI improvements & interactive mode</li> 
</ul> 
<p className="my-page-content"> In short, Shiftpack is a tool that 
<b>reduces migration pain</b>, saves developer time, and minimizes 
errors when upgrading dependencies in React projects. </p>
