Hello all,

I am new to Ionic. I am facing the problem when calling the API (https), it returns 0. After doing some research, I think it’s related to CORS.

The API requires to send Bearer token authorization in the header, thus, it causes the failure.

The API return success in both android phone and web browser, however, in the iOS device, it return 0, I had tried using ionic v4, ionic-native, HTTP, XMLHttpRequest and so on. All are working well in both android phone and web browser except iOS device. I had whitelisted the IP address, adding these kinds of header

headers.append('Access-Control-Allow-Origin' , '*');
headers.append('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, PUT');
headers.append('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
headers.append('withCredentials', 'true');
headers.append('Access-Control-Allow-Credentials', 'true'); 
headers.append('Accept','application/json');
headers.append('Content-Type', 'application/json');

no luck at all. Spending two days on this, no result I can get. Anyone can provide a suggestion?

Thanks.

Hello, I am creating an Ionic project and I’m wondering what dependencies I should set for productions and which for development in the package.json

Do I need to put dependencies such as @ionic-native-… ionic-angular, @angular- in production dependencies of my module? If so, why? Or why not?

As I understand it if I put it in the production dependencies my module will always work in any Ionic version, for example?

Thanks.

Does migrating from Ionic 3 to 4 make sense here?
Our app uses VirtualScroll for lists and allows filtering by substring.
In Ionic 3 this never really worked, to reproduce just scroll down and then filter.
The VirtualScroll list just goes all white instead of showing the filtered elements.
When scrolling manually in Chrome desktop it worked again but this is not good for production use.

Has anyone tried this in Ionic 4 successfully?
Thanks for any hints!

Hi guys this is my first post in this site, I’m working in a App in Ionic 3 that shows current position in the map . as well click start track button we have to add polyline between the lat and lang. I want to draw a Polyline between this markers but i haven’t succeed yet. i know there are some ways to draw polylines my idea is to extract the lat, long coordinates of the marker, save them in a array and then set that as a “path” to draw the Polyline but im having problems with the creation of the array like in the comment below. here is my code:

  startTracking() {

    this.isTracking = true;
    this.trackedRoute = [];
 
    this.positionSubscription = this.geolocation.watchPosition()
      .pipe(
        filter((p) => p.coords !== undefined) //Filter Out Errors
      ).subscribe(data => {
        setTimeout(() => {
          this.trackedRoute.push({ lat: data.coords.latitude, lng: data.coords.longitude });
          this.redrawPath(this.trackedRoute);
        }, 0);
      });
  }
 
  redrawPath(path) {
    if (this.currentMapTrack) {
      this.currentMapTrack.setMap(null);
    }
 
    if (path.length > 1) {
      this.currentMapTrack = new google.maps.Polyline({
        path: path,
        geodesic: true,
        strokeColor: '#ff00ff',
        strokeOpacity: 1.0,
        strokeWeight: 3
      });
      this.currentMapTrack.setMap(this.map);
    }
  }```

HI, I have created a WhatsApp like app in ionic which allows the user to chat, video call and share files.

Since the last relevant (or at least similar) thread concerning encrypting user-data is from May '16, I thought it would make sense to revisit this subject 3 years later (coincidentally, it just so happens that I have a new security requirement!).

Background Info

The apps my organization builds have an offline mandate, dictating that as much of the app can be accessed offline as possible. To facilitate this, as part of the user’s initial authentication response, along with a long-lasting session token, we pass over user profile information needed for logic/UI and other app “secrets”, such as API keys.

This data needs to be encrypted when stored for offline use, as per my organization’s policy. We had achieved this using Intel’s Security plugin, which required no setup, came from a reputable source, and even was (still) endorsed by Microsoft.

This plugin is now dead. The Github repo has been taken down, so we need an alternative.

Encrypting/Decrypting User Profile Data in 2019?

I already have the decryption key value in my head, and understand that it will be stored as plaintext. This has been OK’d as an acceptable necessity.

That said, I’ve evaluated a few options but have concerns for each:

1. WebCrypto – Complex to use, and would require a shim for iOS 10 which we still support.
2. Native Plugins – No “big name” contributors, lots of plugins that haven’t been updated in ages or have side-effects that I can’t enforce with my app crowd, such as forcing an Android user to enable a lock screen to use an app.
3. Javascript Libraries – Wondering if I can use Node’s crypto library, and if not, what is the overhead associated with them?

All three options share the same concern – performance. Since we encrypt API keys, they constantly need to be decrypted within the app. We do not keep API keys decrypted in memory for long, the biggest scope being a local method variable.

I can definitely use some advice, and see if anyone has any opinions/tips/experiences they can share.

TL;DR

1. I need to encrypt certain values in my app so they work offline yet still meet our protocols.
2. My current encryption plugin is dead. It didn’t require any setup and magically encrypted/decrypted values without needing keys.
3. What options exist in 2019 that are performant to continuously encrypt/decrypt from device storage?

Would I then be able to use a command such as ‘ionic cordova platform add ios’ to add iOS as a new platform? Or do the platforms of an app need to be determined at the beginning of development?

There is Location.back(), but it’s not good when current route was first (users can open my app not at root route, and Location.back() will return them to their history)
