Mojo::Phantom to automate a web app

[hussam-qasem]

Is it possible to use @jberger Mojo::Phantom to drive a PhantomJS browser (and automate a web application)?

I would like to expose a [Mojolicious] API that then fetches data from a backend JavaScript web application:

                                Server

                               └────────────────────────────────────────────────┘

Few questions that come to mind:

• Can Mojo::Phantom help me save the resulting web page as an image (for debugging)?
• Is it possible to interact with PhantomJS (e.g., change the screen resolution)?
• Can I run execute JavaScript code and store the JS output in a Perl data structure? (e.g., the result of click_get() in click.t is not stored)
• Does Mojo::Phantom support "click" actions? (e.g. to handle onclick or onsubmit events)

Any advice and recommendation is much appreciated. Thank you!

In theory that would work, but PhantomJS is dead and thus so is Mojo::Phantom. There was some work around using headless chrome but their documentation was so bad that that was abandoned too.

Thank you @jberger for your prompt response. Do any of these functionalities exist today? I'll happily use Mojo::Phantom as-is.

From my little research, Mojo::Phantom appears to be the lightest weight of all: WWW::Mechanize::PhantomJS, Selenium::PhantomJS, etc.

Your input is highly appreciated. Thank you for your time.

I saw this recent article about headless Chrome, so I'll give it a go and report back.

(I'm just falling in love with the Mojo::UserAgent and everything Mojo!)

Perhaps someday we can have a Mojo::Chrome though I see that that still uses Delays rather than async/await, so that shows how old it is.
