Usage

DEMO

ES6 & TypeScript

import { addListener, launch } from 'devtools-detector';
const view = document.createElement('div');
document.body.appendChild(view);

// 1. add listener
addListener(
  isOpen =>
    (view.innerText = isOpen
      ? 'devtools status: open'
      : 'devtools status: close')
);
// 2. launch detect
launch();

AMD

require(['devtools-detector'], function(devtoolsDetector) {
  var view = document.createElement('div');
  document.body.appendChild(view);

  devtoolsDetector.addListener(function(isOpen) {
    view.innerText = isOpen
      ? 'devtools status: open'
      : 'devtools status: close';
  });
  devtoolsDetector.launch();
});

No Module System

<script src="node_modules/devtools-detector/lib/devtools-detector.js"></script>
<script>
  var view = document.createElement('div');
  document.body.appendChild(view);

  devtoolsDetector.addListener(function(isOpen) {
    view.innerText = isOpen
      ? 'devtools status: open'
      : 'devtools status: close';
  });
  devtoolsDetector.launch();
</script>

  isOpen: boolean;
  checkerName: string;
}
  • Listener
type DevtoolsDetectorListener = (isOpen: boolean, detail?: DevtoolsDetail) => void;
  • launch()

    launch detect

  • isLaunch()

    if detect is launched then return true, else return false

  • stop()

    stop detect

  • addListener(listener: DevtoolsDetectorListener)

  • removeListener(listener: DevtoolsDetectorListener)

  • setDetectDelay(value: number)

    Set detect loop delay time, if value =< 0 then stop detecting.

Caveats

  1. In Firefox, if DevTools is undocked, detected only when switching to the Console Panel.
  2. Make sure devtools-detector is the first one to load
