🏗️ How does it work?
To capture console logs and errors and observe API requests, the browser extension wraps around API like console, fetch, XMLHttpRequest to monitor their calls.
To capture Javascript errors, the extension listens to "error" and "unhandledrejection" events.
🚫 Situations where it won't work
Right now we're not able to sniff API response with "content-security-policy" header that has restriction on "script-src"
🔇 How to turn it on / off?
Clicking on the "owl" extension icon will toggle its visibility for the current domain
The first click on each domain requires granting permission for us to access it.
All domains are turned off by default, except for rightonpage.dev .
⭕ What are counted as errors and exceptions?
1) console.error(..) 2) Uncaught JS exceptions 3) Unhandled Promise rejection 4) API responses with status code >= 400 .
❤️ What feature do you love most as the author?
Eating my own dog food, I really love checking and copying API request / response body & headers right on page.
