weinre is a debugger for web pages, like FireBug (for FireFox) and Web Inspector (for WebKit-based browsers), except it's designed to work remotely, and in particular, to allow you debug web pages on a mobile device such as a phone.

I used answer from https://serverfault.com/questions/496169/running-node-js-at-boot, but modified it a little bit:
https://gist.github.com/akuryan/aa458edd325ff840eb97
Modify it so that your User is correct and could launch weinre and have write access to LOG_FILE and LOCK_FILE
Hope, this would help you

We have a video wall with some monitors. each one is plugged into a Raspberry PI 3.
Mostly we just are showing webpages into the video wall (reports, status etc)
Today we control the content of each raspberry using VNC. I was wondering if is there a web service or plugin that allows me to just configure the URL that I wish to show on each screen. Plus, Sometimes we split the each screen into 2 or more webpages.
Is there any web app, chrome plugin or web service that allows me do that?
Thanks
OBS, I don't know if here is the right place to this kind of question. If is there another community where i could ask this, i will be glad to know.
I can not give a complete and exhaustive answer, since you do not provide any description of how it should look and how you want to control it.
Let's start with the fact that almost every browser at startup you can specify URL and start the browser like this:
# firefox https://google.com
Then the browser opens with the page you need.
To close the page, you can kill the browser with a command like this
# killall firefox
You can run commands on the Raspberry PI using ssh, it's much easier than running the VNC session.
Most likely you may encounter a problem when you receive a message stating that the browser can not connect to the display. This is easily correctable with something like:
# export DISPLAY=:0
In order for the browser to always be in full-screen mode and not to lose its settings, you can configure it correctly, close all the tabs and save its configuration from ~/.mozilla/ (for firefox), and then restore it from backup every time you start it.
I am trying to build a simple web application, which capture users photo and sent it my custom server there by connected to some other business use-case. My web page uses HTML's file input control to launch native camera or gallery pick up option.
var input = document.createElement('input');
input.setAttribute('accept', 'image/*');
input.setAttribute('capture', 'camera');
input.setAttribute('type', 'file');
input.click();
This web app, I placed in local webserver with a name "PhotoLocker" and testing with url like
https://localhost(ipaddress to access via mobile browser)/PhotoLocker/index.html
This link is working fine both on desktop and mobile chrome browsers and am able to debug any issues. Where as same link, I try to access from WeChat browser (just opening above link from chat window), it is not at all opening my application in WeChat in app browser.
After googling, I found that https URL scheme is not supported by WeChat. is it True? When I paste the same app url as weixin://ipaddress/PhotoLocker/index.html, I am able to see my web app home page but it is not working as expected.
My Question is - how to debug my webpage opened in WeChat browser? Do I need a official WeChat Dev account even to develop and test sample apps?
Additional Info :
I am able to debug webpage from WeChat web devloper tool as mentioned in below link. But, unable to debug mobile wechat page in this tool. It is always opening chrome dev tools.

I am a frontend developer in China, Chinese. Forgive my English for any mistake, misunderstanding I could make. Some links (dev docs mostly) below contain sites complete in Chinese, because I can not find corresponding English ones for now.
how to debug my webpage opened in WeChat browser?
Tencent provide an IDE for developing regular web interface and WeChat-mini-program, with which developer can directly interact with:
JSSDK (basically a special weixin
Object lives only in in-WeChat-browser);
API provided in WeChat-mini-program.
If you download that IDE:
First it will ask you is to use you WeChat to scan the QRCode, then confirm login with your WeChat account;
Next it will show up two square button (image below), left one is for WeChat-mini-program, the right one is for you to testing regular web page.
Click the right blue one, then you can find your way out, it's just something built top on project Blink.
As you can see the part of debugging regular webpage in WeChat IDE is no more than a simulator (in the WeChat-mini-program part, developer can write code directly in it), and in my experience it does have bugs, you will still need to test code in real machine.
For that Tencent provide another tool called vConsole, tutorials here, with it you can do following things directly in in-WeChat-browsers:
View console logs;
View network requests;
View document elements;
View Cookies and localStorages;
Execute JS command manually
and so on
Do I need a official WeChat Dev account even to develop and test sample apps?
Depends.
You may know the Official Account inside WeChat, with webpages directly opened in any context inside in-WeChat-browser, it will have the ability to interact the weixin Object, or have some API like login with WeChat, pay with WeChat Pay:
API like close current in-WeChat-browser, hide-share-button will not required anything special, you don't need to register any Official Account;
But if you want yo do the Pay, Login thing, you need an Official Account and pay for the ability every year (not sure about this outside China).
The localhost problem you faced
I don't have my working machine with me now so I can not test. Regularly I can proxy localhost with Charles then debugging in WeChat, but never do the https, I will try it later.
All the information got regarding how to debug webpage opened in wechat browser redirects to how to see log or ajax/netwrok calls analysis.
Even with WeChat web devloper tool as mentioned in below link, I am unable to debug mobile wechat page in this tool. It is always opening chrome dev tools.
https://mp.weixin.qq.com/wiki?action=doc&id=mp1455784140&t=0.06697335132505233#1.
Hence further analyzed remote mobile webpage debugging and found that there is no way to put break points, watch, expressions and all just like in chrome dev tools is not possible.
As a work around - you are able to debug code, when you simulate page in dev tools but no way to debug webpage in mobile device.
Same webpage when tried to do remote debugging as per WeChat web devloper tool documentation. here we can only see console logs and network calls.
For my test I need to use secure browser - needs to be run as an application (single exe file) and it lunches to designated site in kiosk mode (disables task switching). Once I'm there it's Angular page so I think it should work but I don't know how to lunch secure browser ?
i dont think this is possibe right now. protractor needs browser specific drivers. have a look at protractor browser support.
Does anyone know if this is possible in J2ME;
I want to have an app that simply launches a browser when opened and directs the browser to a specific web page.
If so, is it widely supported.
You can use javax.microedition.midlet.MIDlet.platformRequest() to launch the browser on almost all phones that support JavaME. This article tells more about invoking platform services such as browser.
Adobe release new interesting product - Adobe Shadow. And in its core is a chrome extension which listen for connection of a remote devices (its also interesting how this is done, but i think its might utilize own http service to communicate such request), but whats more interesting is that it listen for DOM, JavaScript and CSS changes (using chrome inspector for developers) and communicate this changes to othere devices. Yet in manifest this extension is only declare it was aware of only tabs switch activity - how this is possible?
You are incorrect about the Shadow Chrome Extension listening for DOM, JavaScript and CSS changes in the page. When you click on the Remote Inspection button in the Chrome Extension, we open a window to a weinre server and inject the required weinre javascript into the page on the device.The weinre window looks like Chrome Dev Tools because they both use WebInspector, which is part of WebKit.

The Shadow Chrome Extension doesn't listen to anything at the page level. It gets the URL to send out to devices from the tabs permission.
I've only had a quick look at the ("confidential" marked) code I recommend you take a look at the skylab.js file.
It appears they're primarily using WebSockets to make the calls to a service running on your machine at . I'm guessing this belongs to the Adobe Shadow fat client.
Perhaps because your call an already existing service that's running on the local machine Chrome does not require any additional permissions. I've searched the code and see no mention of optional permissions either.
This is very interesting as I imagine this could be a concern for security, but maybe only on machines which are already infected with malicious code.
