React Native API

reload

Apply a downloaded bundle immediately.

Usage

hotUpdater.reload() applies the currently downloaded bundle immediately.

If no new bundle is ready, it reloads the current app code
If a bundle was downloaded, that bundle becomes active immediately

import { hotUpdater } from "./hotUpdater";

async function syncUpdate() {
  const updateInfo = await hotUpdater.checkForUpdate({
    updateStrategy: "appVersion",
  });

  if (!updateInfo) return;

  const didUpdate = await updateInfo.updateBundle();

  if (didUpdate && updateInfo.shouldForceUpdate) {
    await hotUpdater.reload();  
  }
}

Configure init before using this manual flow.

How it restarts

Android: restarts the app process cold, so no native module can reach the JavaScript runtime while it is replaced. The app opens again at its launch screen.
iOS: reloads React Native in place.

A brownfield app should not call reload(); see Brownfield Apps.

updateBundle

Stage a selected transition without reloading the current React Native runtime.

getChannel

The `hotUpdater.getChannel()` function returns the app's current effective channel.
