Extract JS Hook Names
Extract React hook-style function names from pasted JavaScript, TypeScript, JSX, or TSX source snippets without executing, compiling, rendering, fetching, or uploading code.
0 / 30,000 characters. No upload, storage, or account required.
JS hook extraction workflows
Use this extractor when copied React code needs a browser-local custom hook inventory before dependency cleanup, documentation, migration, or frontend architecture review.
Audit React source
Pair hook names with Extract JS React Component Names, Extract JS Function Names, and Extract JS Import Statements.
Review exports and models
Use Extract JS Export Statements, Extract JS Interface Names, and Extract JS Type Aliases.
Clean copied output
Send extracted names to Sort Lines, Remove Duplicate Lines, or Normalize Whitespace.
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.
FAQ
Does Extract JS Hook Names execute React code?
No. It scans pasted source as text and does not execute hooks, render components, compile TypeScript, fetch dependencies, upload, store, or log snippets.
Which hook names are included?
It finds common custom hook declarations and assignments that start with use followed by an uppercase letter, such as useUserProfile or useFeatureFlag.
When is this useful?
Use it while auditing React dependencies, documenting frontend modules, planning migrations, reviewing copied TSX, or cleaning source inventories.
