Question

How can we dynamically retrieve configuration in Ionic 4 for IOS using Socket.io?

I am currently working on an application built with Ionic and socket IO. In the app.module.ts file, the socket import requires a configuration for the URL and options. The issue is that this configuration is hardcoded, and I would prefer to have it dynamically fetched from a form or stored data. I want to avoid having to redeploy the application every time there is a change in the IP address or server port, and I also do not want to rely on a DNS link. Can anyone provide guidance on how to achieve this?

My current setup includes Ionic 5.4.5, Cordova 9.0.0, and deployment on IOS 12.4.

Below is a snippet of my app.module.ts file:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';
import { ErrorHandler } from '@angular/core';
import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';

import { SocketIoModule, SocketIoConfig } from 'ng-socket-io';
const config: SocketIoConfig = { url: 'http://192.168.0.17:3001', options: {} };


@NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [
    BrowserModule,
    IonicModule.forRoot(),
    AppRoutingModule,
    HttpClientModule,
    SocketIoModule.forRoot(config),
  ],
  providers: [
    StatusBar,
    SplashScreen,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Any insights or responses would be greatly appreciated. Thank you.

When it comes to optimizing the loading time of your core application module (app.module.ts) in order to ensure a smooth user experience, it is important to avoid adding heavy business logic that could potentially slow down the load time, especially when fetching dynamic configurations for Socket.io.

A better approach would be to separate the initialization and configuration of Socket.io into another module that can be loaded later in the start-up process of your app.

In a similar scenario, I tackled this issue by:

- opting for a different socket.io client library that does not require initialization through a module: https://github.com/socketio/socket.io-client

- creating a service and incorporating this alternative library:

import { Injectable } from "@angular/core";
import io from "socket.io-client";

export class FoundationProvider {
    public sockets;
}

- implementing a method that handles the initialization process after retrieving the necessary socket config details:

initSocketsIO() {
    if (this.data.userID && this.state.appIsOnline) {
      this.sockets = io(
        this.config.apiBaseUrl + "?_id=" + this.data.userID,
        {
          reconnectionAttempts: 3,
          reconnectionDelay: 10000,
          transports: ['websocket']
        }
      )
      this.sockets.on("snippets", event => {
        this.handleIncomingNotification(event.message);
      })
      this.sockets.on("tasks", event => {
        this.handleIncomingNotification(event.message);
      })
      this.sockets.on("payments", event => {
        this.handleIncomingNotification(event.message);
      })
    };
  };

If you still require the use of your current library, consider relocating it to a more suitable module that loads later in the app's start life cycle, where global configurations and variables are readily available throughout the application. This adjustment should contribute to enhancing the overall performance of your app. Hope this guidance proves beneficial.
