devtools.network

The devtools.network API lets a devtools extension get information about network requests associated with the window that the devtools are attached to (the inspected window).

Like all the devtools APIs, this API is only available to code running in the document defined in the devtools_page manifest.json key, or in other devtools documents created by the extension (such as the panel's own document). See Extending the developer tools for more.

Functions

devtools.network.getHAR()
Get a HAR log for the page loaded in the current tab.

Events

devtools.network.onNavigated
Fired when the user navigates the inspected window to a new page.
devtools.network.onRequestFinished
Fired when the a network request has finished and its details are available to the extension.
