How to save image from url into assets folder

I am using Ionic with Cordova to develop my first Android app and i need to retrieve an image from a REST api and store it on my device, so then i can use it even if the device is offline.

This are the current versions im using:

Ionic:

Ionic CLI : 6.10.1 (C:\Users\agusd\AppData\Roaming\npm\node_modules@ionic\cli) Ionic Framework : @ionic/angular 5.3.1 @angular-devkit/build-angular : 0.901.12 @angular-devkit/schematics : 9.1.12 @angular/cli : 9.1.12 @ionic/angular-toolkit : 2.3.0

Capacitor:

Capacitor CLI : 2.4.0 @capacitor/core : 2.4.0

Cordova:

Cordova CLI : 9.0.0 ([email protected]) Cordova Platforms : android 8.1.0 Cordova Plugins : cordova-plugin-ionic-keyboard 2.2.0, cordova-plugin-ionic-webview 4.2.1, (and 4 other plugins)

I was following a guide meant for Ionic 3 but I couldn't make it work on my current Ionic version.

So far, I have managed to get the JSON object which contains the URL, but i don't know how to download that image and store it into my assets folder.

My code is like this:

api.service.ts:

apiURL = 'my api url...';
 getDiarios() {
    const diarioArgs = {
      method: 'GET',
      mode: 'cors',
      headers: {
        'Content-Type': 'application/json' }
    };
    return this.http.get(this.apiURL, diarioArgs);
  }

Then i have this function, that calls the service and retrieves the response:

data: any;
lastDiario: any;
lastID = 0;

loadLastDiario() {
    try {
      this.apiService.getDiarios().subscribe(
        (data) => {
          this.data = data;
          for (const item of this.data.content) {
            if (item.id > this.lastID) {
              // I get the object with the largest id, which means is the last uploaded
              this.lastID = item.id;
              this.lastDiario = item;
            }
          }
          console.log(this.lastDiario);
          for (const item of this.lastDiario.archivos) {
            // Here is where I need to save every item of "archivos" into my assets folder or any other
            // Every item has an URL property that I can get through **this.lastDiario.archivos.url**
          }
        }
      );
    } catch (error) {
      console.log("Couldn't connect to the service")
    }
  }

If someone could help me, im new to Ionic and Angular in general so any advice will help!

The assets folder is read only at run time.

You can only store files in it during design time.
