Upgrade Guides

Portals Web Plugin 0.8.x → 0.9.0​

  • Portals Web Plugin 0.9.0 is compatible with Portals for Android and Portals for iOS versions 0.8.0 and up.

Breaking Changes​

This release removed the SubscriptionCallback type. This should only affect TypeScript users who were using the type directly. If you were using the type directly, SubscriptionCallback should be replaced with the following, replacing T with the concrete type of the message data:

let callback: (result: PortalMessage<T>) => void;

Portals Web Plugin 0.7.x → 0.8.0​

  • Portals Web Plugin 0.8.0 is compatible with Portals for Android and Portals for iOS versions 0.8.x.
caution

Portals Web Plugin 0.8.0 is a notable update that requires Capacitor 5. Care should be taken to update dependencies across your web content and native apps to ensure compatibility.

First review the Capacitor 5 Update Guide for an overview of necessary changes. Some will not be relevant for Portals apps, but this will be a useful reference in case you encounter issues with your upgrade.

Breaking Changes​

The Portals default export is no longer exposed. All methods are made available as individual module exports. If you wish to still use a Portals namespace just import like the following.

import * as Portals from "@ionic/portals";

The subscribe function now returns a Promise<PluginListenerHandle> instead of a number representing a "subscription reference". PluginListenerHandle has a remove method that can be used for unsubscribing from events. Since PluginListenerHandle is able to manage unsubscribing from events, the unsubscribe function has been removed from the API.

Portals Web Plugin 0.6.x → 0.7.0​

  • Portals Web Plugin 0.7.0 is compatible with Portals for Android and Portals for iOS versions 0.7.x.
caution

Ionic Portals 0.7.0 is a notable update that upgrades the Capacitor dependency to version 4. Care should be taken to update dependencies across your web content and native apps to ensure compatibility.

First review the Capacitor 4 Update Guide for an overview of necessary changes. Some will not be relevant for Portals apps, but this will be a useful reference in case you encounter issues with your upgrade.

Updating Web Content​

Update the Portals Plugin in your web content to 0.7.0. Then, follow the Capacitor 4 Update Guide CLI migration steps to update your web content that uses Capacitor.

Update Native Projects​

Dependency Version Alignment​

The only necessary steps to use Portals version 0.7.0 should be to update dependencies. Portals for iOS version 0.7.0 is compatible with Live Updates 0.2.2 and Official Capacitor Plugins over version 4.0.

InitialContext Update​

A default InitialContext is now always passed to the web content running in a Portal context such that the Portal name will always be accessible.

Before:

export interface InitialContext<T> {
  name: string;
  value: T;
}

After:

export interface InitialContext<T> {
  name: string;
  value: T | undefined;
}

Portals Web Plugin 0.0.x → 0.6.0​

Portals.publish()​

The method signature of Portals.publish() now allows generic typing over PortalMessage instead of restricting generic typing to the data parameter of PortalMessage. The message parameter must be of type string but can be predefined to prevent typos, invalid topic names, etc.

Before:

Portals.publish<string>({ topic: "foo", data: "bar" });

After:

type ValidMessage = { topic: "foo"; data: string };

// TypeScript will reject the following statement:
Portals.publish<ValidMessage>({ topic: "food", data: 1 });

Portals.getInitialContext()​

Portals.getInitialContext() is no longer asynchronous and has been moved out of the Portals class.

Before:

import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import Portals from "@ionic/portals";
import { Capacitor } from "@capacitor/core";

if (!Capacitor.isNativePlatform()) {
  // do something
  (window as any).portalInitialContext = {
    value: { startingRoute: "/" },
  };
}

Portals.getInitialContext<{ startingRoute: string }>().then((context) => {
  ReactDOM.render(
    <React.StrictMode>
      <App context={context.value} />
    </React.StrictMode>,
    document.getElementById("root")
  );
});

After:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import Portals, { getInitialContext } from '@ionic/portals';
import { Capacitor } from '@capacitor/core';

const initialContext = getInitialContext<{ startingRoute: string }>;
const startingRoute = initialContext?.value ?? { startingRoute: '/' };

ReactDOM.render(
  <React.StrictMode>
    <App context={startingRoute} />
  </React.StrictMode>,
  document.getElementById('root'),
);
