What this tool does
Extract JS Media Device Calls scans pasted JavaScript as text, lists navigator.mediaDevices getUserMedia, getDisplayMedia, enumerateDevices, and getSupportedConstraints usage with source-line context, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract MediaDevices API calls from pasted JavaScript, TypeScript, permission prompts, video-call widgets, tests, or copied browser source before camera, microphone, screen-share, privacy, migration, or release QA review.
Use Extract JS Media Device Calls 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, permission prompts, video-call widgets, tests, or copied browser source that may use media device APIs.
- Choose whether duplicate API rows should be removed and whether extracted text should be normalized for comparison.
- Review camera, microphone, screen-capture, and device-enumeration usage with source-line context, then copy the list for privacy QA, migration notes, release review, or documentation.
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 request media permissions.
