Upgrade Guides

Portals for React Native 0.4.0 → 0.5.0​

Portals for React Native version 0.5.0 updates the underlying native Portals libraries to ^0.8.0. This update includes breaking changes to the API. Please read the following carefully to ensure a smooth upgrade.

API Changes​

Breaking​

Pub/Sub​

The pub/sub functionality has been overhauled to lean on React Native's existing event system. To that end, the subscribe method been updated to return an EmitterSubscription and the unsubscribe method has been removed. To stop receiving events, call the remove() method on the EmitterSubscription returned from subscribe.

Portals for React Native 0.3.0 → 0.4.0​

API Changes​

Breaking​

Live Updates​

Updated return values for Live Updates related methods to include more metadata to include the snapshot metadata, the source of the live update (local cache or download), and whether or not the active application path has changed. Affected methods:

  • syncOne
  • syncSome
  • syncAll
Capacitor Plugins​

Capacitor Plugin registration now requires including the iOS Objective-C class name. See How to Use a Capacitor Plugin for the updated API requirements

New​

Shared Assets​

You can now share assets between portals by exposing a location on the device to pull assets from. See Sharing Assets for more information.

Web Vitals​

It is now possible to measure a number of web vitals metrics from your portals in React Native. See Web Vitals for more information.

Portals for React Native 0.2.0 → 0.3.0​

The iOS, Android, and web libraries have all been updated to depend on Capacitor 4. There are no React Native specific code changes needed to adopt these features. However, it will be necessary to follow the iOS and Android upgrade guides to ensure a successful migration.

Portals for React Native 0.1.x → 0.2.0​

API Changes​

Breaking​

Updated function signatures to be async for the following functions:

  • register
  • addPortal
  • syncOne
  • syncSome
  • syncAll

Due to being native calls, these functions were already asynchronous. However, synchronizing these calls via await was impossible due the lack of exposing async via the API. This made all calls to these methods that didn't return a Promise to be fire-and-forget. These API updates allow the user to make that choice at the call-site for themselves.

New​

  • addPortals - enables adding all Portals in a single call instead of having to make N calls to addPortal for each Portal to register.
  • getPortal - enables retrieving a Portal by name
  • enableSecureLiveUpdates - Enables secure live updates for applications if available in App Flow. You must call and await this method before adding any Portals through addPortal or addPortals. If you don't await enableSecureLiveUpdates, you will be unable to sync LiveUpdates in the application.

Static Portal Configuration​

An additional configuration method is now included to support a JSON configuration file to configure Portals on application start. The JSON file must be named portals.config.json and be placed in the application root on iOS and assets root on Android.

JSON Schema​

This Typescript schema is for illustration purposes only.

type PortalConfig = {
  liveUpdatesKey?: string; // The name of the public key file for secure live updates. Must be located in the Bundle.main root on iOS and assets root on Android
  registrationKey?: string; // The portals registration key normally passed to `register`
  portals: []Portal;
}

type Portal = {
  name: string;
  startDir?: string;
  initialContext?: {
    [key: string]: any;
  };
  index?: string;
  liveUpdate?: LiveUpdate
};

type LiveUpdate = {
  appId: string;
  channel: string;
  syncOnAdd: boolean;
};

At a minimum, when including a portals.config.json it must at least have the portals key defined with at least one valid Portal definition in the array. If you are using Live Updates, you must include a LiveUpdate configuration. If you are using Secure Live Updates, you must include the liveUpdatesKey in the configuration.

Portals for React Native 0.0.x → 0.1.0​

The props on PortalView have changed from having individual props of name and initialContext to a single prop named portal.

Before:

<PortalView name="foo" initialContext={{ bar: "baz" }} />

After:

<PortalView
  portal={{
    name: "foo",
    initialContext: {
      bar: "baz",
    },
  }}
/>
