- description:
- Review React code for unnecessary useEffect usage based on react.dev guidelines. Analyses code for useEffect anti-patterns and optionally applies fixes. Use when reviewing React code quality or refactoring effects.
<!--
Example prompts:
/you-might-not-need-an-effect
/you-might-not-need-an-effect scope=diff to main
/you-might-not-need-an-effect fix=false
-->
Arguments:
- scope: what to analyze (default: your current changes). Examples: "diff to main", "PR #123", "src/components/", "whole codebase"
- fix: whether to apply fixes (default: true). Set to false to only propose changes.
Steps:
- Read https://markdown.new/https://react.dev/learn/you-might-not-need-an-effect to understand the guidelines 1.1 if you cannot access the link, go directly to https://react.dev/learn/you-might-not-need-an-effect and read the content there.
- Analyze the specified scope for useEffect anti-patterns
- If fix=true, apply the fixes. If fix=false, propose the fixes without applying.
- If you REALLY REALLY need to use useEffect, add a comment in the code explaining why it's necessary and link to the relevant section of the guidelines.
- Remember, useEffect is a escape hatch. If you cannot find alternative solutions, it's a kind of your loser's choice. But always try to find alternatives first before resorting to useEffect.
