Im happy if even 1 method works

Hello,
I am developing a Ionic app which use node-forge and in the specific I need to generate rsa key pair (forge.pki.rsa.KeyPair) and make sign and verify.
I obtained the key pair and I can sign and verify but I have a problem when I have to store in local storage my KeyPair.
I could convert the PrivateKey into json before the store and then parse the json when I retrieve but there is no way to obtain again a forge.pki.rsa.PrivateKey to use the sign function.
I could convert the PrivateKey into PEM but then when I try to get the privateKey back from the PEM I could just obtain a forge.pki.PrivateKey which doesn’t provide the sign function.
What do you suggest to me?

Hello guys, I’m new to this forum and the Ionic community. I need to learn Ionic for professional reasons and I was wondering if I could get some guidance on this forum.
I’ve read the documentation on how to install Ionic, etc. I’m a bit confused with the information found there. For example, I used the Ionic CLI to generate a new app, this command
ionic start myApp blank, then the documentation says that to run the app I need to run thisionic serve, however when I check the package.json, the script looks different, so I have to use this command instead"start": "ng serve"It looks like an Angular app, why is this?

Hello
Emulating my app for android and trying to store a pdf file with the cordova-file-plugin I get the error message:core.js:1449 ERROR TypeError: Object(…) is not a function
at File.get [as dataDirectory] (index.js:649)
at MergeMapSubscriber.project (euro-bus-test.ts:83)
The code:import {File} from '@ionic-native/file/ngx'; constructor( public navCtrl: NavController, public navParams: NavParams, public http: HttpClient, private storage :Storage, private file: File) { } private downloadFile(url:string, fileName : string): Observable<any> { return this.http.get(url, {responseType: 'blob'}) .flatMap((data: Blob) => { return Observable.from(this.file.writeFile(this.file.dataDirectory, fileName, data, {replace: true})) }) }The error happens in this line of code:
this.file.writeFile(this.file.dataDirectory, fileName, data, {replace: true})
When I check the dataDirectory in the debugger it says:
ioinic-nativ file plugin ReferenceError: documentsDirectory is not defined
When I check this.file.dataDirectory it says: TypeError: Object(…) is not a functionThe other point is, that the import only ‘works’, if I import from ‘file/ngx’ like in shown in the code. Without /ngx the imported ‘File’ is not used in the constructor, and the method writeFile() doesn’t exists (of course).This wasn’t nessecary yesterday.

Good evening,
I have a question about refreshing data which is loaded from an external json file. My script is this for now and at the doRefresh part I have to change something but dont know how
import { Component } from '@angular/core'; import { NavController } from 'ionic-angular'; import { HttpClient } from '@angular/common/http'; import "rxjs/add/operator/map"; @Component({ selector: 'page-home', templateUrl: 'home.html' }) export class HomePage { users=[]; page = 0; maximumPages = 10; text:any = { Year: 'Year', Month: 'Month', Weeks: "Weeks", Days: "Days", Hours: "Hours", Minutes: "Minutes", Seconds: "Seconds", MilliSeconds: "MilliSeconds" }; constructor(public navCtrl: NavController, private httpClient: HttpClient) { this.loadUsers(); } loadUsers(infiniteScroll?) { this.httpClient.get(`http://bla.nl/res/nieuws?page=${this.page}`) .subscribe(res => { this.users = this.users.concat(res['results']); if (infiniteScroll) { infiniteScroll.complete(); } }) } loadMore(infiniteScroll) { this.page++; this.loadUsers(infiniteScroll); if (this.page === this.maximumPages) { infiniteScroll.enable(false); } } doRefresh(refresher) { console.log('Begin async operation', refresher); .subscribe(res => { this.users = this.users.concat(res['results']); }); } }For now I get Declaration or statement expected. How can I add something before .subscribe which can work?

I am doing a post request to my nodeJS server like this.
So whenever i click on the button it gives a post with a JSON: if i console.log the JSON it gives me the good parameters so that’s not the problem.
let data = { username: this.username, email: this.email, password1: this.password1, password2: this.password2 }; this.http.post("http://localhost:3000/", data, {}).subscribe(data => { this.dataUser = data; }, error => { console.log(error); });and from my server.js i do this to get the post but i get a
POST http://localhost:3000/ 404 (Not Found)
so i have no clue how to fix this. On my server side so the server.js file i do this:
app.get("/", (req, res) => { console.log({" / ": true}); request('http://localhost:8100/create-account', function (error, response, body) { res.json(response); if(error) { throw error; } }); });

Hi everyone, I’ve got the following service, which when running on ionic serve, it only calls the rest service once. When running on the device however, it calls it each time.
Why would it be different in the browser and the device? Anything I can do to fix this?
export class RestApiService { wordList: Observable<any>; constructor(private http: HttpClient) { } getDataOnce(): Observable<any> { try { console.log('getDataOnce() '); if (!this.wordList) { console.debug('REST API: ' + apiUrl); const response1 = this.http.get(apiUrl); this.wordList = forkJoin([response1]); } return this.wordList; } catch (e) { console.log(e); } } }ps I know i don’t need the forjoin.

Hello there,
i have the following question:
Besides the distributions for Android and IOS the client wants to use the app in a browser.
So is it possible to send him the “platform -> browser” package, and he is able to start (via shortcut e.g.) the app locally in his browser, without running the serve command?
Info: There will be no native plugins used.Thanks in advance!
