Extract JS React Component Names
Extract React-style component names from pasted JavaScript, JSX, TypeScript, or TSX source snippets without rendering, executing, compiling, fetching, or uploading code.
0 / 30,000 characters. No upload, storage, or account required.
React component extraction workflows
Use this extractor when copied UI code needs a browser-local component inventory before documentation, refactoring, migration, or design-system cleanup.
Audit component libraries
Pair component names with Extract JS Hook Names, Extract JS Class Names, and Extract JS Export Statements.
Clean source before review
Use JavaScript Formatter, Extract JS Import Statements, and Extract JS Function Names.
Polish copied lists
Send extracted names to Sort Lines, Remove Duplicate Lines, or Normalize Whitespace.
What this tool does
Extract JS React Component Names scans pasted source as text, lists PascalCase function, const, and class component names with source lines, removes duplicates, and runs locally in your browser.
Common use cases
Extract React-style component names from pasted JavaScript, JSX, TypeScript, TSX, Next.js route files, Storybook snippets, UI library modules, or copied source before component inventories, design-system audits, documentation, refactors, or migration handoffs.
Use Extract JS React Component 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 components, Next.js route files, copied JSX/TSX modules, Storybook snippets, or component-library source.
- Choose whether duplicate component names should be removed and whether extracted names should be normalized for comparison.
- Review component names with source line numbers, then copy the clean list for UI audits, documentation, refactors, migration plans, or design-system inventory.
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 React Component Names runs locally in your browser. Your pasted code is not uploaded, compiled, rendered, fetched, executed, stored, or logged.
FAQ
Does Extract JS React Component Names render JSX?
No. It scans pasted source as text and does not render JSX, execute components, compile TypeScript, fetch assets, upload, store, or log snippets.
Which component names are included?
It finds common PascalCase function components, const arrow components, and React class components in pasted snippets. It is a lightweight source inventory tool, not a full parser.
When is this useful?
Use it while auditing component libraries, documenting UI modules, preparing migrations, comparing copied source, or planning frontend refactors.
