I am using shell.openExternal(url) method in my push notifications electron app. Onclick of the received push notifications,a new window opens in internet explorer but I want the same to be opened in Chrome.Is it possible?
You can use Child process :
const { exec } = require('child_process');
exec('/usr/bin/chromium-browser https://example.com', (error, stdout, stderr) => {
if (error) {
console.error(`exec error: ${error}`);
return;
}
console.log(`stdout: ${stdout}`);
console.log(`stderr: ${stderr}`);
});
But you must know on which OS you are to give the correct browser executable path.
The previous code works on Linux.
shell.openExternal(url) will open the link in the System Default Browser. Hence, if you want to open it in Chrome, then make it as the default Browser.

I have been using Expo to develop a react-native app, The functionality I am currently trying to implement is to share a link with friends on platforms such as fb messenger/whatapp or even normal texts and when they click this link it will launch my app to a specific page using the parameters.
After extensive research online - I’ve come to a blocker, following expo’s documentation I defined a scheme for my app - when I press share everything works correctly a message is created and I’m able to share content but only as string.
I am using react-natives Share library to share to an app and I’m using Expo to provide me with the link.
Ideally my first goal is to get the app opening using the Expo Link before I explore further into adding more functionality to the link.
Share.share({
message: "Click Here to View More! " + Linking.makeUrl( ' ' , { postkey : "7a5d6w2x9d6s3a28d8d});
url: Linking.makeUrl( ' ' , { pkey : gkey });
title: 'This post is amazing',
})
.then((result) =>{
console.log(result)
if(result === 'dismissedAction'){
return
}
})
.catch((error) => console.log(error))
In the root of my app I have also defined the event handlers: App.js
_handleRedirect=(event)=> {
let {path,queryParams} = Linking.parse(event);
Alert.alert(`queryparams : ${event} path : ${path} `)
this.props.navigation.navigate("Post_Detail",{key:queryParams.postkey})
}
}
componentDidMount() {
let scheme = 'nxet'
Linking.getInitialURL()
.then(url => {
console.log("App.js getInitialURL Triggered")
// this.handleOpenURL({ url });
})
.catch(error => console.error(error));
Linking.addEventListener('url', ({url}) => this._handleRedirect(url));;
}
componentWillUnmount() {
Linking.removeEventListener('url', this.handleOpenURL);
}
When I share the link to Whatsapp, Facebook Messenger or even just messages or notes it appears as myapplink://, I try to enter this into the browser and instead of asking me to open my app - it does a google search.
Please note I am attempting to have this working on Android Device and facing this issue
Is there something I am doing incorrectly?
Any help is much appreciated. Thanks.
You can not open external links, means other than http, https on Android. But you can on iOS. In order to be able to open your expo links, you need proper anchor tags on android. You can create html mails and give it a try, you will see it is gonna work on Android as well.
I have a React Native app that uses Firebase Cloud Messaging with the react-native-firebase package.
I am doing this on the first screen of a React Native app, so after 5 seconds, the user will be sent to a new screen which explains why push notifications are useful, and gives them a button to launch the dialog where they can accept or decline the permission.
setTimeout(() => {
firebase.messaging().hasPermission()
.then(enabled => {
if (enabled) {
// user has permissions
} else {
// user doesn't have permission
this.props.navigation.navigate('EnableNotificationPermissionScreen')
}
});
},
5000);
In the EnableNotificationPermissionScreen screen, there is a button like this:
<Button onPress={this.onSetNotificationPref.bind(this)} title="Set Notification Preference" color="#4ab2fc"/>
Which is handled by an event like this:
onSetNotificationPref() {
firebase.messaging().requestPermission()
.then(() => {
// User has authorized
firebase.analytics().logEvent('messaging_permission_accepted');
this.props.navigation.navigate('App');
})
.catch(error => {
// User has rejected permissions
firebase.analytics().logEvent('messaging_permission_rejected');
this.props.navigation.navigate('App');
});
}
If the user accepts, everything works as I would hope, and the user will have the permission, and will not navigate to that screen again.
However, if the user rejects the permission, I do not want to navigate them to that screen again. As-is, they will be navigated there again because hasPermission will be false. Also, clicking the button to execute requestPermission on that screen will do nothing, as the OS will block requestPermission().
In the examples I have seen, requestPermission is called whenever the permission is not enabled (with no custom screen like this); and so either the dialog pops up, or it doesn't. However, in the flow that I am trying to achieve, I want to navigate to this custom screen only if the user does not have permission because they have not been asked. If they have been asked and declined, they should not be navigated to that screen.
Is there any way to achieve that using the functions in firebase.messaging(), or do I have to use persistent storage like async-storage to track on my own whether the dialog has been shown?
When i try to close the webview with this code:
MessengerExtensions.requestCloseBrowser(function success() {}, function failure(err) {
alert('error closing the window: ' + err); // error closing the window:
console.log(err); // doesn't print
window.close();
});
it closes the webview in iOS, but pops an alert when i try from desktop.
My domain is white-listed, messenger_extensions = true and i enter the page from the desktop messenger and it still doesn't work.
I had before the same problem, but opposite (window closed on desktop, but not on iOS) while trying to use fetch(), and this problem started when started using $.ajax()
before MessengerExtensions.requestCloseBrowser() was invoked from a fetch's promise, and now it's invoked from ajax's success function.
I had to switch fetch with ajax because it didn't work on iOS
Any suggestions?
A day later an error code of 2071011 started to show up, again, only in desktop browsers.
I managed to find a workaround the problem by using window.top.close(); when MessengerExtensions.requestCloseBrowser() fails
It does the same trick on Chrome and asks the user before close on Edge
window.extAsyncInit = function() {
MessengerExtensions.requestCloseBrowser(function success() {
window.close(); // webview closed
}, function error(err) {print ('an error occured');}
);
};
From the documentation on https://developers.facebook.com/docs/messenger-platform/webview/extensions,
window.extAsyncInit() will be called when the Messenger Extensions JS
SDK is done loading. You can use this as a trigger to call other
functions available in the SDK.
I'm using both Google Analytics and branch.io in this website.
The website is designed for mobile.
The problem is that when clicking the banner with text "OPEN", the app cannot be opened.
Here is the code for the click:
$scope.openApp = () => {
let appOpened = false;
const open = () => {
if (!appOpened) {
appOpened = true;
branch.deepviewCta();
}
};
$timeout(open, 1000);
ga('send', 'event', 'homepage', 'download', {
hitCallback() {
open();
}
});
};
If I get rid of the GA code, it works fine:
$scope.openApp = () => {
let appOpened = false;
const open = () => {
if (!appOpened) {
appOpened = true;
branch.deepviewCta();
}
};
$timeout(open, 1000);
open();
};
The reason I put open() in hitCallback is to make sure GA sends out the hit because open() will redirect to another page.
Can you help me?
Alex from Branch.io here:
The Branch deepviewCta() function works on iOS 9+ by triggering an automatic redirect to a Universal Link URL (which opens the app) and then going to a fallback URL if that fails. But Apple is very specific about the situations in which a Universal Link is allowed to launch the app (including things like how long of a pause is allowed before redirection). Of course these restrictions are not public, so all we can do is guess. My suspicion is that putting the deepviewCta() function inside a GA callback is falling outside of Apple’s rules, so the app never opens and you are instead being sent to the fallback URL.
I can think of two options here:
You can build some way to trigger the GA and Branch functions separately so that they don’t conflict with Apple’s requirements.
We actually have a brand new, one-click integration with Google Analytics, which you can read about here and here. If you set that up, you’ll get all Branch-related events automatically instead of needing to manually collect link click data.
Hopefully that helps!
How can I cause Firefox to ignore the Content-Disposition: attachment header?
I find it absolutely annoying that I can't view an image in the browser, because it asks me to download it.
I don't want to download the file, I just want to view it in the browser. If the browser doesn't have a plugin to handle it, then it should ask to download.
E.g. I have Adobe Acrobat Reader installed as a plugin for Firefox. I click a link to a PDF, and it asks me to save it, when it should open in the browser using the plugin. This is the behaviour if the server does not send the Content-Disposition: attachment header in the response.
Firefox 3.6.6
Windows XP SP3
Legacy InlineDisposition 1.0.2.4 by Kai Liu can fix this problem.
In the Classic Add-ons Archive at:
caa:addon/inlinedisposition
The "Open in browser" extension is useful for formats supported natively by the browser, not sure about PDF.
Legacy version 1.18 (for users of browsers such as Waterfox Classic) is in the Classic Add-ons Archive at:
caa:addon/open-in-browser
I also found this tonight that totally prevents Firefox from littering your desktop with downloads. It's actually a redirect fix to the hidden /private/temp folder in MAC. Genius.
You can mimic the Windows behaviour simply by changing [Firefox's]
download directory to /tmp.
To do this, open Firefox's General preferences pane, under Save
Downloaded Files To select [choose].... In the dialog that appears,
hit Shift-Command-G to bring up the Go to Folder dialog.
In this dialog, simply type /tmp, hit OK, then hit Select in the
main window.
Well, that's the purpose of disposition type "attachment".
The default behavior (when the header is absent) should be to display in-line.
Maybe there's a configuration problem in your browser, or the Reader plugin?
For PDFs there is an addon called PDF-Download which overrides any attempt to download a PDF and lets the user decide how they want it downloaded (inline, save, external, etc). You could probably modify it to work for other filetypes too.
You could write a firefox extension that removes the disposition header for PDF files. This would be a fairly simple extension.
Since I was looking for a solution and no available add-on was actually working with my Firefox 31.0 (Ubuntu) I decided to try creating my own add-on.
The code if you want to archive a similar goal or just want to know how it works.
console.log("starting addon to disable content-disposition...");
//getting necessary objects
var {Cc, Ci} = require("chrome");
//creating the observer object which alters the Content-Disposition header to inline
var httpResponseObserver = {
//gets fired whenever a response is getting processed
observe: function(subject, topic, data) {
if (topic == "http-on-examine-response") {
var httpChannel = subject.QueryInterface(Ci.nsIHttpChannel);
httpChannel.setResponseHeader("Content-Disposition", "inline", false);
}
},
//needed for this.observerServer.addObserver --> without addObserver will fail
get observerService() {
return Cc["#mozilla.org/observer-service;1"].getService(Ci.nsIObserverService);
},
//used to register with an observer
register: function() {
console.log("register with an observer to get response-events");
this.observerService.addObserver(this, "http-on-examine-response", false);
},
//used to unregister from the observer
unregister: function() {
console.log("unregister from observer");
this.observerService.removeObserver(this, "http-on-examine-response");
}
};
//gets called at enable or install of the add-on
exports.main = function(options, callbacks) {
console.log("content-dispostion main method got invoked");
//call register to make httpResponseObserver.observe get fired whenever a response gets processed
httpResponseObserver.register();
};
//gets called on disable or uninstall
exports.onUnload = function(reason) {
console.log("content-dispostion unloaded");
//unregister from observer
httpResponseObserver.unregister();
};
/*
//not needed!!! just test code for altering http-request header
var httpRequestObserver =
{
observe: function(subject, topic, data)
{
console.log("in observe...");
console.log("topic is: " + topic);
if (topic == "http-on-modify-request") {
var httpChannel = subject.QueryInterface(Ci.nsIHttpChannel);
httpChannel.setRequestHeader("X-Hello", "World", false);
}
},
get observerService() {
return Cc["#mozilla.org/observer-service;1"].getService(Ci.nsIObserverService);
},
register: function()
{
this.observerService.addObserver(this, "http-on-modify-request", false);
},
unregister: function()
{
this.observerService.removeObserver(this, "http-on-modify-request");
}
};
httpRequestObserver.register();

As an alternative you can get my xpi-File to directly install the add-on in Firefox. If you want to disable the "Content-Disposition" altering just deactivate the add-on ;-).
