A VSCode extension to host the chrome devtools inside of a webview.

If you are looking for a more streamlined and officially supported devtools extension, you should try VS Code - Elements for Microsoft Edge (Chromium)

You can launch the Chrome DevTools hosted in VS Code like you would a debugger, by using a launch.json config file. However, the Chrome DevTools aren't a debugger and any breakpoints set in VS Code won't be hit, you can of course use the script debugger in Chrome DevTools.

To do this in your launch.json add a new debug config with two parameters.

• type - The name of the debugger which must be devtools-for-chrome. Required.
• url - The url to launch Chrome at. Optional.
• file - The local file path to launch Chrome at. Optional.
• request - Whether a new tab in Chrome should be opened launch or to use an exsisting tab attach matched on URL. Optional.
• name - A friendly name to show in the VS Code UI. Required.

• Start chrome with no extensions and remote-debugging enabled on port 9222:
  • chrome.exe --disable-extensions --remote-debugging-port=9222
• Open the devtools inside VS Code:
  • Run the command - DevTools for Chrome: Attach to a target
  • Select a target from the drop down

• Start chrome:
  • Run the command - DevTools for Chrome: Launch Chrome and then attach to a target
  • Navigate to whatever page you want
• Open the devtools inside VS Code:
  • Select a target from the drop down

• Prototyping stage
• Having the DevTools in a non-foreground tab can cause issues while debugging
  • This is due to VS Code suspending script execution of non-foreground webviews
  • The workaround is to put the DevTools in a split view tab so that they are always visible while open
• Chrome browser extensions can sometimes cause the webview to terminate

• Start chrome with remote-debugging enabled on port 9222
  • chrome.exe --disable-extensions --remote-debugging-port=9222
• Run the extension

  • npm run watch or npm run build
  • Open the folder in VSCode
  • F5 to start debugging
