Are extensions run first or scripts? - google-chrome-extension

So, what I'm trying to say is will the extensions you have run before the scripts on the page?
Which one will run first:
extension scripts
or
<script src="websitescript.js"></script>
I'm asking because I wanna make an extension that checks the site. (will check if it's secure or not and use other API's)

Run node script from GUI?

I have a Node.js script.
I want to make GUI with a button and field. Input from the field will be used in a function in the script. I want clicking the button to execute the script (instead of the user having to use the command line).
The script uses multiple Node.js packages, like fs to write files. These packages aren't available in the browser. The script also has API requests that would be blocked by CORS policies. I've looked at using Electron or NodeGUI but I'm not sure if these are the right tools for the job.
The person I am building this GUI for does not want to pay or maintain a server.
What is the best way to create a GUI for this situation?

Is it possible to execute local .exe´s from angular application running in browser?

We are about to start a new project which should be like a desktop app but still run inside a browser for creating items in a system. After these items are created, an .EXE file on the LOCAL machine must be called to do some code generation. Is this possible if using Angular to develop the application or do we need third party libs for executing local .exe's?
No, this is not possible out of the box. Browsers make very sure that local executables cannot be started. You would have to look for other solutions.
One possible idea, depending on how much effort you want to invest, would be to compile the WebKit engine yourself, i.e., create a binary "wrapper" which runs the browser engine itself. Then you are free to extend it in whatever fashion you need, including adding the possibility to start local .exe's (or if those .exe's are your own applications, you could compile them right into your WebKit wrapper).

How can I run a Chrome extension in NW.js?

This question is pretty short and self explanatory. I'm wondering how I can run my Chrome extension in NW.js.
I know you can run an app in NW.js and I think you can run extensions as well?
I can't find much on the topic. Back in 2013 the way to do it seemed to be:
nw [path to manifest.json] --load-extension
Any ideas are appreciated!
Yes you can.
First off, download the extension you want. For this example I'll be using this debugging tool, which adds an additional tab in the dev tools window.
Inside your NW.js package.json file, ensure you have an entry called chromium-args.
Ensure its value contains --enable-extensions --load-extension=relative_path_to_extension_manifest.
My package.json looks like this:
After restarting the application, the extension shows up as expected:
Something I'll add is that the full Chrome API might not be available to you. I couldn't find info about what NW.js supports, but Electron definitely does not support the entire API, so this might have similar restrictions.
I also noticed you mention in the comments that you need to assign a hotkey of sorts. I'd need to know what you were trying to do, but essentially you have the option of either using a browser mechanism such as addEventListener('keydown', myHandler) or using the NW.js API depending on your exact needs.

Node js plugin permissions

I create a web server with Sails.js, and want to allow third dev to create node.js plugins installable from a web page (store).
My problem is I don't want this plugin to require sails (or other critical modules) and have access to database and services and do what they want.
For example using fs and delete all files.
How can I do that ? I have no idea if node.js can lock some scripts on this own directory
I don't think that node expose some sandboxing functionality so when you load a js code into node that code can do what it want.
From your description yours plugins are more like browser javascript code so I think that you can use a headless browser to execute your code and retrieve the result. I've never tried it by myself but it should work. You just have to figure out how to pass parameters to plugin and get the result, also performance will be very bad because the headless browser is quite heavy. Try looking at
http://phantomjs.org/
Another solution is to run the plugins directly inside node but sanitizing the code before running. There are some projects like:
http://gf3.github.io/sandbox/
https://github.com/asvd/jailed
They can help you limiting the powers of the plugins.
Anyway are you sure about it ? in any major CMS platform that I've seen (wordpress, joomla, drupal, liferay ...) the platform's author trusts plugins authors and plugins can always do what they want.

How to you reference a required script that is bundled?

I'm working with the Hot Towel SPA template and I'm trying to add in some data that I want to get from breeze. I have the breeze nuget package installed and the breeze script files are in the scripts folder of the site.
I can reference it by using the actual file name like the following:
define(['durandal/app', '../scripts/breeze.min.js'], function (app, breeze) {
...
});
However, this will break when my site is running in release mode and the script is actually bundled. Plus, it is really ugly and feels like a hack to put the full name in there.
What is the correct way to do this?
By default Durandal loads external libraries via normal script calls not via requirejs. Same is true for HotTowel.
e.g. https://github.com/BlueSpire/Durandal/blob/master/index.html#L31
or if your platform supports it via bundling
https://github.com/johnpapa/PluralsightSpaJumpStartFinal/blob/master/SPAJumpStart/App_Start/BundleConfig.cs#L18
Simply load breeze before requiring main.js and you should be good to go.
