Hello i am new to nativescript-angular trying to solve how router is working.I read the documentation but because i am using a boilerplate i couldnt really understand how it is working...
https://github.com/NativeScript/template-tab-navigation-ng
I only added 1 component to this project which is an empty login component and i set it as a root component.
What i am trying to do is how do i switch from my login component to tabs component ? with button func
app-routing.module.js:
import { NgModule } from "#angular/core";
import { Routes } from "#angular/router";
import { NativeScriptRouterModule } from "nativescript-angular/router";
import { LoginComponent } from './login/login.component';
const routes: Routes = [
{ path: 'login', component: LoginComponent },
{ path: "", redirectTo: "/tabs", pathMatch: "full" },
{ path: "tabs", loadChildren: "./tabs/tabs.module#TabsModule" }
];
#NgModule({
imports: [NativeScriptRouterModule.forRoot(routes)],
exports: [NativeScriptRouterModule]
})
export class AppRoutingModule { }
app.module.ts:
import { NgModule, NgModuleFactoryLoader, NO_ERRORS_SCHEMA } from "#angular/core";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { AppRoutingModule } from "./app-routing.module";
import { AppComponent } from "./app.component";
import { LoginComponent } from "./login/login.component";
#NgModule({
bootstrap: [
LoginComponent
],
imports: [
NativeScriptModule,
AppRoutingModule,
],
declarations: [
AppComponent,
LoginComponent
],
schemas: [
NO_ERRORS_SCHEMA
]
})
export class AppModule { }
just add a link to your component tab in your login component
this.router.navigate(["/tabs"]);

I'm trying to upgrade an angularjs directive to use it my angular component. I've gotten the hybrid (ng1 + ng2) environment to work. I can also inject angularjs services in angular and use them in angular components (I actually got this working even with angularjs 1.4.x).
Now I'm trying to use an existing angularjs directive in angular, but not working.
For reference, are some snippets of my codes.

I found the answer in this link https://github.com/angular/angular/issues/14993 (inspired by BrunoPoeta)
See comment by gkalpak on March 10.
Now let's see if I can upgrade a regular directive and use 1.4.x.
I have two shared modules Core and MasterData.
I am facing issue to use MasterData module's components in my applcation though i can use Core Module's Components. Following is my code.
Core Module (core.module.ts)
import { NgModule, ModuleWithProviders, ComponentFactoryResolver } from '#angular/core';
import { CommonModule } from '#angular/common';
import { RouterModule } from '#angular/router';
import { FormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
import {
IgHierarchicalGridComponent,
IgPivotGridComponent,
IgGridComponent
} from 'igniteui-angular2';
import { CacheModule } from 'angular2-cache';
import { AUTH_PROVIDERS } from 'angular2-jwt';
import { CoreComponents, EntryCoreComponents } from './components';
import { CoreService } from './services';
import { ClientInfoServiceProvider } from './client-info';
import { AuthGuard } from './guards/auth.guard';
const IgniteuiComponents = [
IgHierarchicalGridComponent,
IgPivotGridComponent,
IgGridComponent
];
#NgModule({
declarations: [
...CoreComponents,
...IgniteuiComponents
],
providers: [
...CoreService,
AUTH_PROVIDERS,
AuthGuard,
ClientInfoServiceProvider
],
imports: [
CommonModule,
FormsModule,
RouterModule,
HttpModule,
CacheModule,
],
entryComponents: [
...EntryCoreComponents
],
exports: [
HttpModule,
CacheModule,
RouterModule,
FormsModule,
...CoreComponents,
...IgniteuiComponents
]
})
export class CoreModule {
static forRoot(): ModuleWithProviders {
return {
ngModule: QmsCoreModule,
providers: [
...CoreService,
AUTH_PROVIDERS,
AuthGuard,
ClientInfoServiceProvider
]
};
}
}
Master Data Module (which is inheriting Core because I use infragistics library in core and masterdata components) (masterdata.module.ts)
import { NgModule, ModuleWithProviders, ComponentFactoryResolver } from '#angular/core';
import { CommonModule } from '#angular/common';
import { RouterModule } from '#angular/router';
import { FormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
import { QmsCoreModule } from 'qms/core/qms-core.module';
import { MasterdataComponents } from './components';
import { MasterdataServices } from './services';
#NgModule({
imports: [
CommonModule,
FormsModule,
RouterModule,
HttpModule,
QmsCoreModule.forRoot()
],
declarations: [
...MasterdataComponents
],
providers: [
...MasterdataServices
],
exports: [
FormsModule,
RouterModule,
HttpModule,
QmsCoreModule,
...MasterdataComponents
]
})
export class QmsMasterdataModule {
static forRoot(): ModuleWithProviders {
return {
ngModule: QmsMasterdataModule,
providers: [
...MasterdataServices
]
};
}
}
Master data Module has currently only one component name TeamGrid. (Component Selector is ‘team-grid’)
Main Application AppModule (app.module.ts)
import { BrowserModule } from '#angular/platform-browser';
import { NgModule, Provider } from '#angular/core';
import { QmsMasterdataModule } from 'qms/masterdata/qms-masterdata.module';
import { SwacProxyInterface } from 'qms/core/swac';
import { AppRoutingModule } from './app-routing.module';
import { HomeModule } from './home/home.module';
import { ProjectModule } from './project/project.module';
import { AppComponent } from './app.component';
import { SharedServices } from './shared/services';
export const AppModule = (proxyInterface: SwacProxyInterface, provider: Provider[]) => {
#NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
AppRoutingModule,
HomeModule,
ProjectModule,
QmsMasterdataModule.forRoot()
],
providers: [
SharedServices,
...provider
],
bootstrap: [AppComponent]
})
class AppModule {
}
return AppModule;
};
Error message is:
'team-grid' is not a known element:
1. If 'team-grid' is an Angular component, then verify that it is part of this module.
2. If 'team-grid' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '#NgModule.schemas' of this component to suppress this message.
("
[ERROR ->]<team-grid></team-grid>
Can someone help me to find the correct solution for this?
Above Implementation is correct but only mistake is that each modules (Home.module / Project.module) under App.module should also import masterdata.module or core.module as per required compoenents.
This might help you to find out root cause
shared.module.ts
import { NgModule } from '#angular/core';
import { FormsModule } from '#angular/forms';
import { ReactiveFormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
import { QmsMasterdataModule } from 'qms/masterdata/qms-masterdata.module';
#NgModule({
declarations: [
],
imports: [
CoreModule,
QmsMasterdataModule
],
exports: [
CoreModule,
QmsMasterdataModule
]
})
export class SharedModule {
}
App Module
import {SharedModule} from './modules/shared/shared.module';
export const AppModule = (proxyInterface: SwacProxyInterface, provider: Provider[]) => {
#NgModule({
declarations: [
AppComponent
],
imports: [
SharedModule
],
providers: [
],
bootstrap: [AppComponent]
})
class AppModule {
}
return AppModule;
};
I am getting error "Can't resolve all parameters for RouteParams while creating a basic app for routing"
Below is my app.module.ts file looks like
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
import { App } from './app';
import { routing } from './components/appRouting/app.routing';
import { LoginComponent } from './components/login/loginComponent';
import {SliderMenuComponent} from './components/sliderMenu/sliderMenuComponent';
#NgModule({
imports: [
BrowserModule,
FormsModule,
routing,
HttpModule
],
declarations: [App,LoginComponent,SliderMenuComponent],
providers: [],
bootstrap: [App]
})
export class AppModule { }
My app.routing.ts looks like as below:
import { ModuleWithProviders } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
import {LoginComponent} from '../login/loginComponent';
import {SliderMenuComponent} from '../sliderMenu/sliderMenuComponent';
const appRoutes: Routes = [
{
path: '',
redirectTo: '/login',
pathMatch: 'full'
},
{ path: 'login', component: LoginComponent },
{ path: 'slider', component: SliderMenuComponent }
];
export const appRoutingProviders: any[] = [
];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes);
My app.ts looks like below:
import {Component} from '#angular/core';
#Component({
selector: 'app',
template : `
<h1 class="title">Component Router</h1>
<nav>
<a routerLink="/slider" routerLinkActive="active">Slider</a>
<a routerLink="/login" routerLinkActive="active">Login</a>
</nav>
<router-outlet></router-outlet>
`
})
export class App {
}
updated the angular router to "#angular/router": "3.0.0-rc.2" and it's working now
app.routing.ts
import { Routes, RouterModule } from '#angular/router';
import { LoginComponent } from './components/login/login.component';
import { TestsComponent } from './components/tests/tests.component';
import { NotFoundComponent } from './components/notfound/notfound.component';
import { AppModule } from './app.module';
const appRoutes: Routes = [
{ path: 'anmelden', component: LoginComponent },
{ path: 'tests', component: TestsComponent },
{ path: '**', component: NotFoundComponent }
];
export const appRoutingProviders: any[] = [
];
export const routing: AppModule = RouterModule.forRoot(appRoutes);
app.module.ts
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { routing,
appRoutingProviders } from './app.routing';
import { AppComponent } from './components/app/app.component';
import { LoginComponent } from './components/login/login.component';
import { TestsComponent } from './components/tests/tests.component';
import { NotFoundComponent } from './components/notfound/notfound.component';
#NgModule({
declarations: [ AppComponent, LoginComponent, TestsComponent, NotFoundComponent ],
imports: [ BrowserModule, routing ],
providers: [ appRoutingProviders ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
The result:
Edit:
This errors only occurs when using npm start. If I delete the imports: row in the module run npm start and add this line again everything works fine.
I have my root module which looks like this:
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { routing, appRoutingProviders } from './app.routing';
import { LoginModule } from './login/login.module';
import { UserModule } from './user/user.module';
import { NavbarModule } from './navbar/navbar.module';
import { AppComponent } from './app.component';
#NgModule({
imports: [ BrowserModule, routing, NavbarModule ],
declarations: [ AppComponent ],
providers: [ appRoutingProviders ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
I am writing a navbar with various components that handle various parts of the navbar (Im just trying to be really granular, sort of like spotify's approach).
So in the end I will have lots of components that all add up to once navbar, so that felt like a pretty natural use of a module? So I created a navbar module:
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { NavbarComponent } from './navbar.component';
#NgModule({
imports: [ ],
declarations: [ NavbarComponent ],
providers: [ ],
bootstrap: [ NavbarComponent ]
})
export class NavbarModule { }
for the sake of the example ill stick to one navbar component which looks like this
import { Component } from '#angular/core';
#Component({
selector: 'navbar',
templateUrl: './navbar.template.html'
})
export class NavbarComponent { }
the html template just contains standard bootstrap navbar code...
So as you can see I have imported the NavbarModule into the AppModule, which from my understanding of how modules work, should make the NavbarComponent available to all the components I define in the AppModule?
So when I use
in my html template for AppComponent it should render out the NavbarComponent stuff? Instead it just keeps an empty navbar tag?
Any ideas? Also if my understanding of how modules and their imports works is totally off, please could you link some material that could clarify this for me? I have read the angular docs and this is where I got my current understanding from.
Thanks
I found my problem. In the metadata of my navbar module, I was not exporting the navbar component, therefore it was not available to modules that imported it! Solution below
navbar.module
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { NavbarComponent } from './navbar.component';
#NgModule({
imports: [ ],
declarations: [ NavbarComponent ],
providers: [ ],
exports: [ NavbarComponent ],
bootstrap: [ NavbarComponent ]
})
export class NavbarModule { }
