Open HTML in chrome from command line using app flag

Question

(Before downvote im aware how to do this using code thats inline to this command but not how to do it using a file that uses the --app="data:text/html,<sometags></sometags>)

How would I open a local html (mar.html) file using this command C:\'Program Files (x86)'\Google\Chrome\Application\chrome.exe --profile-directory="Default" --app=

Specifically, the issue is my lack of familiarity with the --app flag

I tried

C:\'Program Files (x86)'\Google\Chrome\Application\chrome.exe --profile-directory="Default" --app="mar.html"

C:\'Program Files (x86)'\Google\Chrome\Application\chrome.exe --profile-directory="Default" --app="file:///mar.html"

Both don't work.

Giving me the error

Your file was not found It may have been moved or deleted. ERR_FILE_NOT_FOUND

@AndersonScoutodaSilva it doesn't mention at all how to open it using a **local** html file but only with URLs — Mark, May 29 '17 at 12:04

You almost got it. The file descriptor path must be absolute and encoded. Encoding the path correctly with cli tools like "urlencode"(gridsite-clients) did not work for me.

If you have NodeJS installed and would use a linux machine, you could use this command.

chromium --app=`node -e "console.log('file://'+encodeURI(process.argv[1]))" "$(realpath "/path/of/your/file.html")"`

This works also fine with relative paths.
For windows you have to rewrite this yourself.
