What is the recommended technology or technologies to use in order to make a web page that automatically updates the screen depending on a value change in a database?
For example, there is a web page with a button. When the button is pressed, a corresponding value in a database is changed from off to on. When this is completed, the database is checked again and the button on the web page changes to the corresponding state (either on or off).
Several web pages may be open on different devices and they must also change.
I have looked into Node.js with Express and Socket.io but it seems to have relatively little documentation and I was wondering if this can all just be accomplished in another way since JavaScript is pretty slow (I think).

Meteor JS might interest you, if you don't mind its bleeding edge status. Its very fancy javascript framework that does a lot of realtime updates and concurrency. Very cool.

I have to create an admin panel that will rely on an API I created.
I would like to use an framework that will speed up my dev. (create request based on field provided by user, search ,etc)
To make it , I want to make a single app REST API client front-end. I didn't find a framework that could do that easily (for example : one that use a rest api client and a another front-end app)
Any ideas ?
No one will choose that for you. Go to this website:
http://nodeframework.com/
And read about all of the framkeworks there. Compare their differences and see which is the best tool for the job for you. Every one of them has its use, every one of them is good for something, every one of them has its strengths and its weaknesses. For API development most of the people choose Express, Hapi, Restify or LoopBack but there are much more than just those few to choose from. You need to test for yourself which works for you.

I'm wondering, if there is Axure RP alternative for a better price. I used other apps, but ended with Axure RP because of two fundamental advantages:
it's not only wireframe tool, but it lets me prototype whole web/app with functional demonstrations
it generates/exports prototype and customers can easily try personaly (it's HTML site and i upload it to my server and clients just get email with link to follow)
So, is there anything else like Axure RP meeting my two criteria with better price? All apps i've seen mainly fail in second condition.
Yes - atomic.io lets you do both of these things.
You can go from low fidelity, right up to fully functioning prototypes that use things like logic, data, and variables.
You can also easily share an URL with anyone. (see: https://atomic.io/learn/sharing)
And there is a free plan. :-)
atomic.io
You can use moqups.com , it's a web app.
it lets you to make prototypes with linked pages and more .
also it lets you to share your Design through a URL on its site.
There are a ton of prototyping tools.
https://www.cooper.com/prototyping-tools
It always depends on what your main goal to achieve is.
Justinmind (https://www.justinmind.com) is very close to Axure.
If you do not mind sharing your prototypes you can look into a bunch of different tools that are webbased (i.e. https://www.figma.com)

Im trying to make load testing for web application that based on Webrtc,
does someone knows with whitch tool can I test that application.
also I`d like to know if i can use Jmeter and if so , how can i use it ?
thanks a head
When it comes to load testing, WebRTC is different. And that's because WebRTC is peer-to-peer and not client server.
What you can test is the client server part, more specifically the signaling server and the STUN/TURN server. For these, you can easily use JMeter as for any web server. For STUN/TURN just follow the specs (though if you're using an existing server, I would leave this into the authors hands, unless you want to involve in that project too). For the signaling server, it depends on how you build it.
What you can also do with WebRTC is try to test with a controlled limited bandwidth and delay/jitter. This will be more like a smoke test, than a load one. To do this automatically is a little bit more complicated. especially if you want to do it with audio/video, not data.

At the moment we are a small development team of 2. All our software is used inhouse. Currently staff just walk to our desk when they want new software developed or when they want new features added to existing software, or when bugs arise.
I am looking for a better management process of this. Do I get staff to send an email instead and then that can be designated to a developer. Or is there a simple software app out there that could help?
I want a simple method for doing this as the staff are unlikely to use something if too time consuming or complex. They find it too easy to approach a developer personally!
Anything to recommend please?
One option is to use JIRA. It has a feature where emails sent to a certain address can get turned in to backlog items (using the email subject line as the title).
Keep it as it is for now: face-to-face communication is always better than using any piece of software...
It will be only when you will grow to more developers that you will really need such software: from online or cloud based (ie Zimbra) to VCSs (version control systems) hosted on your machines.

I'm new to SharePoint and I'm looking for resources to exemplify a good layout for a project management oriented site. I've made a Project site, but that's as far as I've gotten. Has anyone run across any good resources for this?
If you've started with a Project Site, your Task List and Calendar are going to do quite a bit for you. There's a few options you'll want to turn on, such as the Timeline in the Task List. Dig around your available Apps and experiment with what you see. You'll likely need a List for something, so check out custom lists while you're experimenting (they operate a bit like an Excel spreadsheet).
Since you're new to SharePoint, you might consider looking for O'Reilly's Information Architecture for the World Wide Web. If you'll be doing much more site design, that book will help you determine what sites need and how they should be organized. It's a fantastic book and not difficult to read, although the second half of the book is pretty specific to coded web design, which isn't what SharePoint is for new users.
