Upgrade Instructions

ionic-angular 3.9.0 adds support for @angular 5.0.0 🎉! It is a drop-in replacement for ionic-angular 3.8.x.

To update, remove existing node_modules and any lock files, and then update package.json to the following deps.

"dependencies" : {
  ...
  "@angular/common": "5.0.0",
  "@angular/compiler": "5.0.0",
  "@angular/compiler-cli": "5.0.0",
  "@angular/core": "5.0.0",
  "@angular/forms": "5.0.0",
  "@angular/http": "5.0.0",
  "@angular/platform-browser": "5.0.0",
  "@angular/platform-browser-dynamic": "5.0.0",
  "@ionic/storage": "2.1.3",
  "ionic-angular": "3.9.0",
  "rxjs": "5.5.2",
  "zone.js": "0.8.18"
  ...
},
"devDependencies: {
  "@ionic/app-scripts": "3.1.0"
  "typescript" : "2.4.2"
}

If your app uses RXJS, see the instructions below to update.

RXJS 5.5.2 Updates

The recent update of RXJS includes a change in how operators are applied.

Traditionally, operators were applied like this:

import 'rxjs/add/operator/debounceTime';
import 'rxjs/add/operator/switchMap';

export MyClass {


  someMethod(){
    // Using Reactive Forms
    this.input.valueChanges
    .debounceTime(500)
    .switchMap(inputVal => this.service.get(inputVal))
    .subscribe(res => console.log(res))
  }
}

This approach involved modifying the Observable prototype and patching on the
methods.

RXJS 5.5 introduces a different way to do this that can lead to significantly
smaller code bundles, lettable operators.

To use lettable operators, modify the code from above to look like this:

//Use Deep imports here for smallest bunlde size
import { debounceTime } from 'rxjs/operators/debounceTime';
import { switch } from 'rxjs/operators/switchMap';

export MyClass {


  someMethod(){
    // Using Reactive Forms
    // We use the new `.pipe` method on the observable
    // too apply operators now

    this.input.valueChanges
    .pipe(
      debounceTime(500),
      switchMap(inputVal => this.service.get(inputVal))
    )
    .subscribe(res => console.log(res))
  }
}

This slight change allows only import the operators we need in our code. This will result in a smaller, faster application. This example uses Deep Imports, which allow the module we want to import to be isolated.
