I couldn't load an external image using an url variable.
The problem is that Angular auto complete the url to add localhost:3000/ at the beguining of the url.
Here is my component:
import { Component, Input, OnInit } from '#angular/core';
import { Cite } from './cite';
import { Engin } from './engin';
import { Station } from './station';
import { EnginService } from './engin.service';
#Component({
moduleId: module.id,
selector: 'my-engin-detail',
template: `
{{imgUrl}}
<img [src]= "imgUrl" width="42" height="42" />
`,
styles: [`
`]
})
export class EnginDetailComponent implements OnInit {
constructor(private enginService: EnginService) {
}
#Input()
engin: Engin;
imgUrl: string;
ngOnInit(): void {
this.enginService.getImgUrl(this.engin.id_engin)
.then(url => this.imgUrl = url);
}
}
the output is
192.168.0.102/resultsdetails/image/assets/E207_1.png //that's => {{imgUrl}}
ERROR 404 :
http://localhost:3000/192.168.0.102/resultsdetails/image/assets/E207_1.png
404 (Not Found)
Here angular2 compiler autocomplete the url with "http://localhost:3000/" and i don't want that.
However this works fine:
<img src="192.168.0.102/resultsdetails/image/assets/E207_1.png" width="42" height="42/>
So, I don't know how to inject a variable in the [src] without an autocompletion with /localhost:3000
In case of "relative" url you have, it could be done like this:
<img [src]= "'//' + imgUrl" width="42" height="42" />

I'm using Angular 12 and am writing a simple group tab app. I'm working on the config page component and the html looks like this:
<br />
<br />
<br />
<p>Configuration 3</p>
<input type="text" placeholder="Some Test" />
In a normal browser, the text and box appears. But if I try to do the same thing via the install to tab path, I don't get the text or input box at all.
I think this might have something to do with routing but can't confirm.
The app-routing-module is pretty simple:
const routes: Routes = [
{
path: '',
component: HomeComponent,
},
{
path: 'configuration',
component: ConfigurationComponent,
},
];
#NgModule({
imports: [
RouterModule.forRoot(routes, {
initialNavigation:
!BrowserUtils.isInIframe() && !BrowserUtils.isInPopup()
? 'enabled'
: 'disabled',
}),
],
exports: [RouterModule],
})
export class AppRoutingModule {}
So what does it take to get the SPA to route to the configuration page when used within teams?
Configuration Component: (URL purposed changed to protect the innocent)
import { Component, OnInit } from '#angular/core';
import { Inject, AfterViewInit, ElementRef } from '#angular/core';
import { DOCUMENT } from '#angular/common';
import * as microsoftTeams from '#microsoft/teams-js';
#Component({
selector: 'app-configuration',
templateUrl: './configuration.component.html',
styleUrls: ['./configuration.component.scss'],
})
export class ConfigurationComponent implements OnInit, AfterViewInit {
constructor(
#Inject(DOCUMENT) private document: Document,
private elementRef: ElementRef
) {}
ngOnInit(): void {
microsoftTeams.initialize();
}
ngAfterViewInit() {
console.log('Initializing ms teams');
microsoftTeams.settings.registerOnSaveHandler((saveEvent) => {
microsoftTeams.settings.setSettings({
entityId: '',
contentUrl: 'https://test.ngrok.io',
suggestedDisplayName: 'Test',
websiteUrl: 'https://test.ngrok.io',
});
saveEvent.notifySuccess();
});
console.log('Register on save');
microsoftTeams.settings.setValidityState(true);
}
}
Thanks,

In order to render a tab in Teams. You need to make sure that it is iFramable. Please see the document- Tab requirements.
Make sure that you have given the domain in valid domains in your manifest.
Please share more details like console error, what are you using static tab or config and manifest, if issue isn't solve for you
I traced my problem for this particular question to the line:
initialNavigation:
!BrowserUtils.isInIframe() && !BrowserUtils.isInPopup()
? 'enabled'
: 'disabled',
This example is in a lot of the code for SPAs in and Teams Tabs.
I just have it set to 'enabled' for now and I can get beyond the purpose of this question.
I have created a very simple custom validator for a simple form control, e.g. MatInput, which would always return non-null e.g. invalid. I hav also added one of the pre-built validators e.g. required. When I start my app I can see that status = INVALID and errors.required = true.
Once I start typing, I expected that status will remain INVALID and errors.myError = true, but this does not happen. What am I doing wrong? I have built my example on StackBlitz. I have also added the contents on my TS & HTML files below
TS
import { Component } from '#angular/core';
import { AbstractControl, FormControl, ValidationErrors, ValidatorFn, Validators} from '#angular/forms';
export function myValidator(): ValidatorFn {
return (control: AbstractControl): ValidationErrors | null => {
return { "myError": true };
};
}
#Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
name = new FormControl('', [Validators.required, myValidator]);
}
HTML
<label>
Name:
<input type="text" [formControl]="name">
</label>
{{ name | json }}
I am quite new to Angular and I am not sure how to debug this. What can I try next?
TL;DR:
export class AppComponent {
name = new FormControl('', [Validators.required, myValidator()]);
}
Explanation:
myValidator is not being called, so you are not getting the ValidatorFn
I am unable to get the nativescript-videorecorder to work in my app.
I had installed the plugin and used the code given on the github https://github.com/triniwiz/nativescript-videorecorder for typescript. I created a simple HTML ui and tried to call a function to open the camera to record video. However it is does not work
For app.component.html i used the tag <Image src="videoCam" (tap)="onCam()">
For app.component.ts i used the below code
import { VideoRecorder, Options as VideoRecorderOptions } from 'nativescript-videorecorder';
#Component({
moduleId: module.id,
selector: "ns-app",
templateUrl: "app.component.html"
})
export class AppComponent {
export class AppComponent {
onCam() {
const options: VideoRecorderOptions = {
hd: true
saveToGallery: true
};
const videorecorder = new VideoRecorder(options);
videorecorder.record().then((data) => {
console.log(data.file)
}).catch((err) => {
console.log(err)
});
}
}
Is there anything i am missing to get this to work ?
I'm trying to get up and rolling with Vue Native, and I'm running into the same error whenever I attempt to navigate beyond the initial screen
Warning: React.createElement: type is invalid -- expected a string
(for built-in components) or a class/function (for composite
components) but got: undefined. You likely forgot to export your
component from the file it's defined in, or you might have mixed up
default and named imports.
Check the render method of ReactVueComponent.
in ReactVueComponent (at SceneView.js:17)
in SceneView (at CardStack.js:466)
in RCTView (at View.js:60)
in View (at createAnimatedComponent.js:154)
in AnimatedComponent (at Card.js:12)
When searching my dir for ReactVueComponent, it doesn't exist, nor does SceneView.js, nor does RCTCView, etc. My guess is that's because they are generated with the code compiles?
My router, index.vue is set up as follows
<template>
<root>
<app-navigation></app-navigation>
</root>
</template>
<script>
import React from "react";
import { StackNavigator, navigationService } from "vue-native-router";
import { Root } from "native-base";
import WelcomeScreen from "./screen/WelcomeScreen.vue";
import HomeScreen from "./screen/home.vue";
const AppNavigation = StackNavigator(
{
Welcome: { screen: WelcomeScreen },
Home: { screen: HomeScreen }
},
{
initialRouteName: "Welcome",
headerMode: "none"
}
);
export default {
components: { Root, AppNavigation }
};
</script>
My WelcomeScreen component(this loads correctly. The button, on push, throws the error)
<template>
<nb-content padder>
<nb-form>
<view :style="{marginTop:300}">
<nb-button block :on-press="login">
<nb-text>Login</nb-text>
</nb-button>
</view>
</nb-content>
</template>
<script>
import { Dimensions, Platform, AsyncStorage } from "react-native";
import { NavigationActions } from "vue-native-router";
export default {
props: {
navigation: {
type: Object
}
},
methods: {
login() {
this.navigation.navigate("Home");
}
}
};
</script>
The HomeScreen component, which fails to render:
<template>
<nb-container :style="{flex:1, backgroundColor: '#fff'}">
<nb-header>
<nb-body>
<nb-title>title</nb-title>
</nb-body>
</nb-header>
<nb-content>
<nb-list>
<li>thing 1</li>
<li>thing 2</li>
<li>thing 3</li>
</nb-list>
</nb-content>
</nb-container>
</template>
<script>
import React from "react";
import { Dimensions } from "react-native";
const SCREEN_WIDTH = Dimensions.get("window").width;
export default {
props: {
navigation: Object
}
};
</script>
Any tips on this would be much appreciated. Not much out there on Vue Native yet, and I've tried to follow the few examples I've seen to the best of my ability. Double and triple-checked my dependencies and they all seem to be in place.
Seems like you are using <li> tags which are not supported. If you check native base docs. The correct tag to be used within nb-list is nb-list-item. http://docs.nativebase.io/Components.html#list-def-headref
I have a minimalist Nativescript hello world application. It has just 2 screens, 'Login' and 'List'.
Here is the flow:
User presses the login button in first screen.
Second screen is shown, which is suppose to show the list of names; but which shows nothing.
If I type even a single character in text field, it shows the list.
I have been scouring over Stack Overflow and Github, it seems the problem others are facing is a bit complicated, like "list not getting updated after http call" etc.
So it seems I am making some obvious mistake here, because this basic scenario should 'just work'. But that small mistake alludes me.
Here is my login file:
/*login.component.ts*/
import { Component } from "#angular/core";
import firebase = require("nativescript-plugin-firebase");
import * as Rx from "rxjs";
import { MyFireLoginService } from '../../mobile-fire/fire-login.service'
import { Router } from "#angular/router";
import { Observable } from "rxjs/Observable";
#Component({
selector: "login",
templateUrl: './pages/login/login.component.html',
styleUrls: ['./pages/login/login.component.css']
})
export class LoginComponent {
email: string = 'user1#site.com';
password: string = 'password';
user: Observable<any>;
constructor(private fl: MyFireLoginService, private router: Router) {
this.email = 'user1#site.com';
this.password = 'password';
this.user = fl.authState;
this.watchUser();
}
watchUser(): void {
this.user.subscribe((usr) => {
if (usr.uid) {
this.router.navigate(["/list"]);
}
})
}
login(): void {
this.fl.loginWithEmail(this.email, this.password)
}
}
and list file:
import { Component } from "#angular/core";
import firebase = require("nativescript-plugin-firebase");
import * as Rx from "rxjs";
import { MyFireLoginService } from '../../mobile-fire/fire-login.service'
import { Router } from "#angular/router";
import { Observable } from "rxjs/Observable";
#Component({
selector: "list",
templateUrl: './pages/list/list.component.html',
styleUrls: ['./pages/list/list.component.css']
})
export class ListComponent {
items: any[] = [];
user: Observable<any>;
constructor(private fl: MyFireLoginService,
private router: Router) {
this.user = fl.authState;
this.watchUser();
this.items = [{
name: 'aks1'
}, {
name: 'aks2'
}, {
name: 'aks3'
}]
}
watchUser(): void {
this.user.subscribe((usr) => {
if (!usr.uid) {
this.router.navigate(["/"]);
}
})
}
private textChanged(e: any): void {
console.log(e.value);
// console.dir(this.items);
}
logout() {
this.fl.logout()
}
}
list.component.html
<ActionBar title="List" class="action-bar"></ActionBar>
<StackLayout>
<Button class="submit-button" text="Logout" (tap)="logout()"></Button>
<TextField hint="empty field for testing.." (textChange)="textChanged($event)"></TextField>
<Label *ngFor="let item of items" [text]="item.name"></Label>
<!-- <GridLayout>
<ListView id="list-of-items" [items]="items" class="small-spacing">
<ng-template let-item="item">
<Label [text]="item.name" class="medium-spacing"></Label>
</ng-template>

</StackLayout>
login.component.html
<ActionBar title="Login" class="action-bar"></ActionBar>
<StackLayout>
<Button class="submit-button" text="Sign in" (tap)="login()"></Button>
<Label text="Hello world"></Label>
</StackLayout>
EDIT: Here are the log for the life-cycle events of two components:
JS: LOGIN:ngDoCheck called
JS: LOGIN:ngAfterContentChecked called
JS: LOGIN:ngAfterViewChecked called
JS: Auth state changed.
JS: a <==== This is me typing 'a' in the textbox of LIST component
JS: LOGIN:ngDoCheck called
JS: LOGIN:ngAfterContentChecked called
JS: LOGIN:ngAfterViewChecked called
JS: LIST:ngOnInit called
JS: LIST:ngDoCheck called
JS: LIST:ngAfterContentInit called
JS: LIST:ngAfterContentChecked called
JS: LIST:ngAfterViewChecked called
What I find strange is that List component's init is not called until I type 'a' in the textbox inside List component. Also, LOGIN component's life-cycle events are called even after is it gone out of view.
Update1: I followed the tutorial on nativescript.org. The code there seems to be working fine. I suspect, there is something wrong with inclusion of firebase plugin. Will update when I know more.
Update2: I stubbed parts of firebase api I am using, it worked fine with dummy APIs.
