is it possible to open a particular browser in node js? There is the Open module that opens the default browser but i would like to open IE in certain circumstances
Well the open modules allows you to specify the program:
open("http://nodejs.org", "iexplore");
That said, take a look at what open is actually doing under the hood (assuming Windows)
var exec = require('child_process').exec
exec('start "" "iexplore" "http://nodejs.org"')

I am trying to create a desktop app using electron which includes a function where a user can open a desired file saved in the local storage. Sine I am using MacOS, I want to use nodejs to be able to open the file (e.g. PDF doc) in the default preview software. is there any way to do this?
Thank you in advance.
A portable way is to make use of the Electron's shell API, specifically the shell.openPath method:
const { shell } = require('electron');
shell.openPath("/fullpath/to/file");
It is available both in the main process and in the renderer process, and it can also be used to open a folder in the Finder.
if anyone is wondering I found a way of using
const { exec } = require('child_process')
exec('open ~/path/to/file')
this used command shell (terminal) to open it. If there is any other better way to do it please let us know!
I have an Electron App in which when users click on a button I want to open file explorer (or Finder on Mac) for users to choose a path in their file system. Then I want to use this path to save a file.
The second part is quiet easy to achieve. I just need to use writeFile() from node File System API.
However I have gone through the full list of node File System API and I have found nothing allowing me to do the first part.
You should use dialogue module. Simple example for showing the file explorer will be:
const {dialog} = require('electron')
console.log(dialog.showOpenDialog({properties: ['openFile', 'openDirectory', 'multiSelections']}))
Check this link for more information.
You all know open npm package: https://www.npmjs.com/package/open
Using this package, one can write the following code:
var open = require('./node_modules/open/lib/open.js')
open('http://www.cnn.com')
and activating it by:
$ node app.js
will open a browser window of cnn.com.
I want my script to open this site and inject some code to the console. I mean that the browser will behave like I clicked F12, went to 'console' tab and typed in console the code:
alert('Hello World')
Do you know how to do it?
The open module is used to "Open a file or url in the user's preferred application."
It can open the preferred application (a browser in this case) but it cannot control it. In fact, it doesn't even know what browser will that be (or even if that will be a browser).
What you are asking for can be achieved with tools like PhantomJS ("PhantomJS is a headless WebKit scriptable with a JavaScript API."), Nightmare.js ("A high-level browser automation library.") or CasperJS ("Navigation scripting & testing for PhantomJS and SlimerJS"), see:
http://phantomjs.org/
http://www.nightmarejs.org/

following case.
I have a python script that opens a firefox browser on windows which has a firefox addon installed that writes logs into the local storage.
Before I close the browser via python I would like to read out the log information out of the local storage of the firefox.
So how can I access the localStorage in the firefox?
Help very appreciated.
You will have to use PyXPCOM and the nsIDOMStorageManager interface.
Have a look at this tutorial to see how to use PyXPCOM.
You may start from this code (untested):
from xpcom import components
principal = (components.classes['#mozilla.org/scriptsecuritymanager;1']
.getService(components.interfaces.nsIScriptSecurityManager)
.getNoAppCodebasePrincipal(YOUR_URL))
dom_storage_manager = (components.classes['#mozilla.org/dom/localStorage-manager;1']
.getService(components.interfaces.nsIDOMStorageManager))
local_storage = dom_storage_manager.getLocalStorageForPrincipal(principal, YOUR_URL)
I wan't to protect the code of my node-webkit desktop application packaged in an exe file.
The problem is not on the file directly but with the dedicated port for remote debugging.
Perhaps I haven't understood something but, on Windows, if I execute a "netstat -a -o" command, I see an open port associated to the application and if I open this port on my browser, I have a page with "Inspectable WebContents" and a link to the webkit application.
With this debug window, it's possible to access to all the sources of the app and I don't know how to disable this feature.
For now, I think there is no actual way to disable remote debugging in nw.js.
Even so, according to the wiki, remote debugging seems to only be executed through the command line switches. Therefore you can block the chromium command line switches (or only --remote-debugging-port) to prevent arbitrary remote debugging by user until nw.js supports disabling functionality of remote debugging.
For instance:
const gui = require('nw.gui');
const app = gui.App;
for (let element of app.fullArgv) {
// app.argv has only user's switches except for the chromium args
if (app.argv.indexOf(element) < 0) {
app.quit(1); // invalid args!
}
}
However, I am not quite sure the above code could protect your application code, because the nw.js is using Chromium internally. So that, the application code would be extracted in temporary folder on initialization. Whereas above solution isn't really protect your nw.js application. See more details: https://github.com/nwjs/nw.js/issues/269
Note: node-webkit has changed name to nw.js
