I want to be able to create a new html file that will be displayed and saved on the server for future use when a new user logs into their account. Can this be done using JavaScript or are there any libraries that I could get that would be able to do this?
This can be done through use of the fs module in node. See https://nodejs.org/api/fs.html.
However, it is very likely that this is not the best solution to the problem your solving. Instead of creating a new html file for every user, you probably want to save user details in a database and have a single html file that can be populated with the data when it's needed.
This is not possible with JavaScript alone unless you use Node.js. Otherwise will need PHP or a similar server-side language.
If you go that route, here is a nice tutorial that may be beneficial to you:

I have a basic knowledge of SQL and a basic knowledge of JS, mostly from school. I'm looking forward a way to create a HTML/CSS/JS webpage in local to query (select/insert/update) a SQL Database, but I saw a lot of different ways to do it. I need some help to get through the vastity of all those info. Which are the easiest ways to achieve my goal and which are the most up-to-date ones today?
Try node.js is you prefer JS on server. It has loads of libraries allowing connections to pretty much all databases out there.
There are very helpful tutorials on youtube showing how to start. Here is one of them.

I'm creating a client side application that will rely only on a remote mysql database, all the project use vuejs. Is there any js library that can work into the browser to save and retrive data on the remote mysql db?
Well, the simplest answer is "you should never do it".
Because do this on the "client side" is not secure, you will expose sensitive information about your database, and this is not okay.
You can see here why
However, if you really want to (just don't), here is, is really old but is because is not a good thing to do, but you can try.

Is there any web API that takes a URL and gives back the readable content of that page? Or is there any javascript library that can do this?
Installing node.js or any server-side app is not possible.
That's actually a really hard problem. Such questions usually imply that you want sidebars and similar 'noise' elements excluded. This is often solved with different training sets within the machine learning computer domain and it's not easy to develop.
Having said that - take a look at:
http://www.alchemyapi.com/api/scrape/
http://www.readability.com/developers/api
http://www.diffbot.com/
This should help you to learn enough about the space that you'll be able to do better searches for you problem domain.
I think you could find some related services on Mashape (http://www.mashape.com/).
Search for 'text'. Like this: https://www.mashape.com/search?query=text
There are several NLP / Analysis providers there, and most of them are freemium.
OTOH, there's also a project called boilerpipe. You can test its quality at the URL below:

What's the best choice to stress test a node.js powered server? I need to send a lot of single request and measure the delay time and validate the response. If possible I need to export data or generate graphics.
If you're willing to pay a little bit for the service, blitz.io can be a good way to go. Otherwise, apache benchmark is also a nice option, though you'll have to work a little harder for response validation and graphics.
A cluster of JMeter instances would do the trick. JMeter can export all the measurements and you can use Excel^H^H^H^H^Hyour favourite spreadsheet to do the graphics.
Try Vegeta. It focuses on making it easy to achieve a target rate of requests per second. I mean you can test your service's behavior at multiple requests per second. What about your report requirement, here you can also add -output flag which specifies the output file to which the binary results will be written to.

we want to provide an online bookmark service to our customers. Therefor it would be nice to provide also a function to store local bookmarks into our online tool. This shouldn't be done automatically - the user should confirm this action (only in case someone thinks I want to spy users data).
I'm looking for a while now, but I found only that there is no solution, because it's a security risk. Is there a way or already a tool for such a functionality in Javascript?
Regards
This is completely impossible.
You need to write a browser addon.
Is there a way or already a tool for such a functionality in Javascript?
Nope, definitely not. Maybe for browser extensions - if it's possible even for them.
No there isn't any solution to do this via javascript. The only solution I can think of is to use a Java Applet to read the client's computer and look for the bookmark.
Another way is you can ask them to export their favorites to a file and upload to your website.
Prompt the user to upload the bookmarks file: http://productforums.google.com/forum/#!topic/chrome/i1r3CgqvgCI
