Problem Description

I'd like to have more control over the chrome renderer including flags and command line options.

There are experimental features of chrome I would like to play with.

These can be accessed in a browser as chrome://flags but this URL doesn't work with Electron.

Additionally there are command line arguments I'd like to specify like '--disable-site-isolation-trials' which would allow me to work around a bug that impact Electron right now.

Looks like it 'might' be able to do this now with --enable-feature= but I don't have a list of features to test it out with.

[MarshallOfSound]

Chrome features that are flagged can be enabled / disabled with --enable-features and --disable-features.

Other cli flags can also be provided. You do both of these through the command line API

I'm trying to manupilate these two flags inside Chrome, but it seems that these flags don't have corresponding cli flags. The flags I've encontered are enable-media-session-service and hardware-media-key-handling. They can be changed by chrome://flags//#enable-media-session-service and chrome://flags//#hardware-media-key-handling How can I disable it?

I've searched it a lot but didn't find solution or workaround.

Thanks

Any solution for this ?

@mingjun97 in case you are still wandering, and someone searching for this issue, I found a workaround:

Open some task manager, you should be able to see many renderer processes of chrome, and their command lines, take a screenshot or copy one of those, especially enable-features and disable-features.

Then disable/enable desired flags in chrome, restart chrome, and copy those command line again:

In my case, It is HardwareMediaKeyHandling,MediaSessionService in disable-features.

Add them using

app.commandLine.appendSwitch('disable-features', 'HardwareMediaKeyHandling,MediaSessionService');

before app's ready event triggered. Works fine with electron 7.x and 8.x on Linux, which disable chromium's poor MPRIS implementation.

You don't need to use the task manager - just go to chrome://version.

How can I enable experimental web assembly features?

Is there a way to pass this on the command line itself rather than in the source code?

I'm wanting to pass  --window-size=1024,640 --force-device-scale-factor=1.25 --device-scale-factor=1.25

Into an existing application but have been unsuccessful

Hi @MarshallOfSound
Hope you're doing well!

Any idea how we can enable Chrome policy via the command line, for example, enable CloudAPAuthEnabled, or needs to request that as a feature to support it by electron itself?

Thanks in advance!
