JS Web Worker URL extraction workflows
Use this extractor when pasted browser source needs a local inventory of worker scripts before PWA, caching, build, or release QA review.
Review background scripts
Pair worker URLs with Extract JS Service Worker Paths, Extract Script Sources, and Extract JS Dynamic Imports.
Audit network handoffs
Compare worker paths with Extract JS Fetch URLs, Extract JS WebSocket URLs, and JavaScript Formatter.
Clean copied output
Send extracted URLs to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
Quick answer

What this tool does
Extract JS Web Worker URLs scans pasted JavaScript as text, lists Worker and SharedWorker constructor script paths, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract Web Worker script URLs from pasted JavaScript, TypeScript, PWA source, background-task snippets, tests, or copied browser code before worker inventory, migration, caching, or release QA review.
Use Extract JS Web Worker URLs 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 JavaScript, TypeScript, browser snippets, tests, or copied source that may contain this browser API behavior.
- Choose whether duplicate API rows should be removed and whether extracted text should be normalized for comparison.
- Review API usage with source-line context, then copy the list for QA, migration tickets, documentation, release notes, or handoffs.
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
This extractor runs locally in your browser. Your pasted code is not uploaded, executed, rendered, fetched, bundled, stored, logged, or used to trigger browser behavior.

Does Extract JS Web Worker URLs start workers?
No. It scans pasted source text locally and does not execute JavaScript, create Worker instances, fetch worker scripts, upload, store, or log snippets.
Which worker patterns are included?
It finds literal script paths passed to new Worker(...) and new SharedWorker(...) so worker files can be reviewed safely.
When is this useful?
Use it while auditing browser APIs, migration notes, release QA handoffs, documentation, or source inventories without running pasted code.
