headless browser in DSM for python

[iStone]

don't if this is the correct subgroup to ask, please move there if needed.

-------
anyone tried above topic? would be nice to have a self-contained headless browser like PhantomJS...

The current possible headless browsers like Firefox or Chrome still need a complete installation... (aka no-go)



thanks for sharing your experience/ thoughts.

Why I cannot edit the post anymore?

BTW: it seems even if use node.js (DSM included) also need Chrome or Firefox installed, to be able to use headless browser..

Any comments are appreciated!

It seems the only way is go Docker?

Just installed it inside docker, but haven't tested it. Will post back.

you installed Chrome or Firefox apt-get into Dcoker ubuntu Xvfb?

man, why is it so complicate to get a headless browser there? any alternative like PhantomJS or for node.js?

 

[Rusty]

No I haven’t. No time today to play around with it. Will try tomorrow.

thanks for taking time...

really fascinating when learning docker => Keras model => Tensorflow => eager execution ... hope I could understand these and try these soon... or one day.. ;-)

I installed Firefox in Docker ubuntu... file exchange with host(synoNAS) also works...
but get disappointed about Synology & DSM, why do we need to install another Linux(ubuntu) in a encapsulated "Docker" and then can we "apt install firefox", such a redundant use of SynoNAS( running GNU-linux)...

now within this encapsulated Linux, I have to setup development env. again (user, profile, python etc.)

Would that be possible just simply install firefox/chrome into SynoNAS as it is already a Linux?

Officially no, not without breaking something.

Just my personal view: DSM NAS is an appliance that happens to be based on tailored version of Linux. The appliance supports different functions through mandatory packages and user-installable packages. This is the official mechanism for adding features. There is access to the underlying DSM Linux for administrators, not standard users, which implies it's provided for maintaining the platform and not day-to-day functionality.

As such (and why I don't use the DSM Linux as a general purpose device) when updating DSM there is no guarantee that any modifications will not be removed or disabled, not for any malicious reason but generally through the assumption of the upgrade process not expecting user modifications and so overwriting a whole set of folders.

The docker approach means you can update DSM and pretty well know that your contains should still work afterwards.

Of course there's nothing to stop you trying to mod the Linux, but it's not for me!

just found out PhantomJS still works! with this:

driver.set_window_size(1024, 768)   # ! important

BTW: For 3 headless browser the speed ranks (fast to slow) as Chrome, PhantomJS, FF.

If you don’t mind me asking, why do you need a “headless browser”?

 

[iStone]

web scraping. Do you have a alernative solution or somewhat familiar with these?

 

[WST16]

No. I don't know much about it. Just trying to understand and learn.
"Why?" is very powerful. Thanks for answering
