# React Audit Grep Patterns

Find every upgrade landmine in a React codebase before you touch it

## What this does

Before upgrading React, you want to know what in your codebase is going to break. This is a ready-made library of search commands that finds the problem spots for you - old APIs, unsafe lifecycles, test issues, dependency clashes. Use it when you are auditing rather than midway through fixing.

### Top 3 things it does for you

- Scan a codebase for deprecated and removed React APIs
- Turn up unsafe lifecycle methods and batching problems
- Catch test-file issues and dependency conflicts ahead of the upgrade

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About React Audit Grep Patterns

A verified library of grep scan commands for auditing a React codebase ahead of a React 18.3.1 or React 19 upgrade. It is meant to be used when running a migration audit, including by the react18-auditor and react19-auditor agents.

The patterns cover deprecated APIs, removed APIs, unsafe lifecycle methods, batching vulnerabilities, test file issues, dependency conflicts, and the removals specific to React 19.

Use it when writing audit scan commands rather than recalling grep syntax, particularly for the multi-line async setState patterns, which need context flags to match.
