What this tool does
Extract JS Hook Names scans pasted source as text, lists custom hook declarations and hook variable assignments with source lines, removes duplicates, and runs locally in your browser.
Common use cases
Extract React custom hook names from pasted JavaScript, JSX, TypeScript, TSX, frontend utility modules, Next.js files, or copied source before dependency audits, documentation, cleanup, refactors, migration planning, or design-system reviews.
Use Extract JS Hook Names when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste React hooks, TSX components, copied utility modules, Next.js files, or frontend source snippets that may contain custom hooks.
- Choose whether duplicate hook names should be removed and whether extracted names should be normalized for comparison.
- Review hook names with source line numbers, then copy the clean list for dependency audits, refactors, documentation, migration planning, or design-system reviews.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Extract JS Hook Names runs locally in your browser. Your pasted code is not uploaded, compiled, rendered, fetched, executed, stored, or logged.
