I have 2 different Angular apps [Product View and Product Cart] and a shell application. All 3 apps are hosted on different ports. In the shell application I have integrated above apps using module federation. Both apps perfectly work for different routes. Here is my shell app routing code:
const routes: Routes = [
{
path: '',
component: HomeComponent,
children : [
{
path: '',
outlet:'pView',
loadChildren: () =>
loadRemoteModule({
remoteEntry: 'http://localhost:3000/remoteEntry.js',
remoteName: 'mfe1',
exposedModule: './Module',
}).then((m) => {
return m.MicrofrontendModule;
}),
},
{
path: '',
outlet:'pCart',
loadChildren: () =>
loadRemoteModule({
remoteEntry: 'http://localhost:7000/remoteEntry.js',
remoteName: 'mfe2',
exposedModule: './Module1',
}).then((m) => {
return m.Microfrontend1Module;
}).catch(err => console.log('Error loading remote entries', err)),
},
],
pathMatch: 'full',
},
{
path: 'child',
outlet:'',
loadChildren: () =>
loadRemoteModule({
remoteEntry: 'http://localhost:8000/remoteEntry.js',
remoteName: 'mfe3',
exposedModule: './Module3',
}).then((m) => {
return m.Microfrontend2Module;
}),
},
];
And my html code to load above 2 apps is as below :
<div class="container" style="width: 99%;">
<table class="table" style="width:100%;margin-top: 0px; border: 2px solid white">
<tbody>
<tr>
<td>
<div style="width: 500px; height: 370px; border: 1px solid rosybrown">
<router-outlet name="pView"></router-outlet>
</div>
</td>
<td>
<div style="width: 500px; height: 370px; border: 1px solid green">
<router-outlet name="pCart"></router-outlet>
</div>
</td>
</tr>
It is working fine but I am getting below error after one of my remote app is down.
GET http://localhost:7000/remoteEntry.js net::ERR_CONNECTION_REFUSED
I have tried to load remote apps before Shell app Bootstrap in main.ts as
import { loadRemoteEntry } from '@angular-architects/module-federation';
Promise.all([
loadRemoteEntry('http://localhost:3000/remoteEntry.js','mfe1'),
loadRemoteEntry('http://localhost:7000/remoteEntry.js','mfe2'),
loadRemoteEntry('http://localhost:8000/remoteEntry.js','mfe3')
])
.catch(err => console.log('Error loading remote entries', err))
.then(() => import('./bootstrap'))
.catch(err => console.log(err));
// import('./bootstrap').catch(err => console.error(err));
But still getting same error. Anyone kindly help me on this.
The solution is to provide a placeholder module in catch and further implement errorcomponet in placeholder [error module] as
loadChildren: () =>
loadRemoteModule({
remoteEntry: 'http://localhost:8000/remoteEntry.js',
remoteName: 'mfe3',
exposedModule: './Module3',
}).then((m) => {
return m.Microfrontend2Module;
})
.catch(e => {
return import('src/app/placeholder/error.module').then(m => m.ErrorModule);
})
},
