Convert jQuery to React — automatically
jQuery powered the web for fifteen years, and millions of production apps still depend on it — selectors mutating the DOM, event handlers bound in ready() blocks, state scattered across data attributes. Rewriting that by hand into React means re-discovering every implicit behavior the hard way.
CodeShift converts jQuery codebases to React 18 + TypeScript automatically. The engine maps your scripts, plugins and DOM touchpoints, then rewrites them as declarative function components with hooks, typed props, and predictable state — not a mechanical wrapper, a real re-architecture. Every file is verified against the original for behavior parity, and the output ships with tests and a full diff.

How the migration engine works
Analyze
The whole repository is scanned: framework and version detected, every dependency mapped, risks flagged before a line is touched.
Plan
A dependency-aware migration plan orders files leaves-first, so everything a file imports is migrated before the file itself.
Rewrite
Each file is restructured into modern, idiomatic architecture — streamed live, with already-migrated symbols kept consistent across files.
Verify
Every file passes structural checks and an adversarial behavior-parity review; failures are repaired automatically before you see them.
jQuery to React: frequently asked questions
Can jQuery code be converted to React automatically?+
Yes. CodeShift analyzes your jQuery code's DOM manipulation, events and implicit state, then rewrites it as component-based React 18 with hooks and TypeScript. It's a re-architecture into idiomatic React, not a find-and-replace, and every file is verified for behavior parity.
What happens to jQuery plugins?+
The engine identifies each plugin's role and replaces it with a maintained React equivalent or a small typed component, flagging anything that needs a human decision in the migration plan before rewriting starts.
Do I get TypeScript?+
Yes — the default jQuery migration target is React 18 + TypeScript + Vite, with typed props and state throughout.
Will the new React app behave the same as the old site?+
Each rewritten file passes a behavior-parity verification step against the original, is auto-repaired if it fails, and ships with generated tests plus a side-by-side diff so you can confirm every decision.
