2. Auto-start DevTools

To start development, you normally need to launch your browser (perhaps in incognito mode), open DevTools, and navigate to a local URL. The whole process can be automated in a single click by adding options to the browser launch command.

It’s best to create a new shortcut or script to launch in development mode then, for Google Chrome add:

--incognito to start in incognito mode

--auto-open-devtools-for-tabs to start DevTools

and place the testing URL at the end, e.g. http://localhost:8000/

On Windows devices, a shortcut could therefore point to:

"C:\Program Files\Google\Chrome\Application\chrome.exe" --incognito --auto-open-devtools-for-tabs http://localhost:8000

Other useful Chrome switches include:

--allow-insecure-localhost to ignore SSL errors on localhost domains

--disable-extentions to start without extensions which could possibly affect rendering, e.g. ad blockers

--window-size=, to set an initial window size

--window-position=, to set an initial window position
