Supabase Provider

This guide walks you through setting up hot-updater with Supabase in a React Native project. You'll configure the environment, install required packages, and initialize Supabase for seamless updates.

Prerequisites

Before you begin, make sure the following are ready:

Docker Or OrbStack: Install it via Docker or OrbStack.
Node.js: Version 20 or later is recommended.
Supabase CLI: Install it via npx supabase.
Supabase Account: Sign up at Supabase if you don’t have one.

Step 1: Install Required Packages

Run the following command to install dependencies:

npm

pnpm

yarn

npm install hot-updater --save-dev

Step 2: Configure Supabase

Run the initialization script to start the interactive setup process. Use the following command with your preferred package manager:

npm

pnpm

yarn

npx -y supabase login
npx hot-updater init

Interactive Setup Steps

Select a Build Plugin: Choose a build plugin for your project (e.g., Metro for React Native).
Select a Provider: Select Supabase as the provider for handling updates.

During the setup, you will be prompted to:

Create or Select a Supabase Organization: Choose an existing organization or create a new one.
Create or Select a Project: Choose an existing project or create a new one within your organization.
Configure Storage: Select an existing storage bucket or create a new public bucket to store updates.
Database Migration: create a new one to store updates.
Deploy Edge Function: Deploy a Supabase Edge Function called update-server.

Once the setup is complete, a .env file will be generated containing the following keys:

HOT_UPDATER_SUPABASE_ANON_KEY=your-anon-key
HOT_UPDATER_SUPABASE_BUCKET_NAME=your-bucket-name
HOT_UPDATER_SUPABASE_URL=https://your-project-id.supabase.co

WARNING

If you’re not using the react-native-dotenv solution, the tokens from your .env file will not be included in your app bundle and are therefore not exposed to risks. However, if you’re still concerned,

please refer to the article below for more details: Security

Step 3: Generated Configurations

During the initialization process, the following file is automatically generated:

hot-updater.config.ts: This file contains the configuration settings for integrating Supabase with your project.

hot-updater.config.ts

import { metro } from "@hot-updater/metro";
import { supabaseDatabase, supabaseStorage } from "@hot-updater/supabase";
import { defineConfig } from "hot-updater";
import "dotenv/config";

export default defineConfig({
  build: metro({ enableHermes: true }),
  storage: supabaseStorage({
    supabaseUrl: process.env.HOT_UPDATER_SUPABASE_URL!,
    supabaseAnonKey: process.env.HOT_UPDATER_SUPABASE_ANON_KEY!,
    bucketName: process.env.HOT_UPDATER_SUPABASE_BUCKET_NAME!,
  }),
  database: supabaseDatabase({
    supabaseUrl: process.env.HOT_UPDATER_SUPABASE_URL!,
    supabaseAnonKey: process.env.HOT_UPDATER_SUPABASE_ANON_KEY!,
  }),
});

Step 4: Add HotUpdater to Your Project

The HotUpdater component wraps your application, enabling seamless delivery of updates and fallback UI during updates. Follow these steps to integrate it into your App.tsx:

App.tsx

import { HotUpdater } from "@hot-updater/react-native";

function App() {
  return (
    <View>
      <Text>Hello World</Text>
    </View>
  );
}

export default HotUpdater.wrap({ 
  source: "https://<project-id>.supabase.co/functions/v1/update-server", 
  requestHeaders: {
    // if you want to use the request headers, you can add them here
  },
  fallbackComponent: ({ progress, status }) => (
    <View
      style={{
        flex: 1,
        padding: 20,
        borderRadius: 10,
        justifyContent: "center",
        alignItems: "center",
        backgroundColor: "rgba(0, 0, 0, 0.5)",
      }}
    >
      {/* You can put a splash image here. */}

      <Text style={{ color: "white", fontSize: 20, fontWeight: "bold" }}>
        {status === "UPDATING" ? "Updating..." : "Checking for Update..."}
      </Text>
      {progress > 0 ? (
        <Text style={{ color: "white", fontSize: 20, fontWeight: "bold" }}>
          {Math.round(progress * 100)}%
        </Text>
      ) : null}
    </View>
  ),
})(App);

Step 5: Add Babel Plugin to Your Project

In this step, you will configure Babel to set the bundle ID at build time. This is necessary for integrating the hot-updater plugin into your project.

Add the following to your babel.config.js file:

babel.config.js

module.exports = {
  presets: ['module:@react-native/babel-preset'],
  plugins: [
    'hot-updater/babel-plugin', 
  ],
};

Step 6: Add Native Code

To complete the integration of hot-updater, you'll need to add native code modifications for both Android and iOS platforms. This step ensures the hot-updater can interact with your app's underlying framework to apply updates seamlessly.

Android

Kotlin

Java

android/app/src/main/java/com/<your-app-name>/MainApplication.kt

package com.hotupdaterexample

import android.app.Application
import com.facebook.react.PackageList
import com.facebook.react.ReactApplication
import com.facebook.react.ReactHost
import com.facebook.react.ReactNativeHost
import com.facebook.react.ReactPackage
import com.facebook.react.defaults.DefaultNewArchitectureEntryPoint.load
import com.facebook.react.defaults.DefaultReactHost.getDefaultReactHost
import com.facebook.react.defaults.DefaultReactNativeHost
import com.facebook.react.soloader.OpenSourceMergedSoMapping
import com.facebook.soloader.SoLoader
import com.hotupdater.HotUpdater 

class MainApplication : Application(), ReactApplication {

  override val reactNativeHost: ReactNativeHost =
      object : DefaultReactNativeHost(this) {
        override fun getPackages(): List<ReactPackage> =
            PackageList(this).packages.apply {
              // Packages that cannot be autolinked yet can be added manually here, for example:
              // add(MyReactNativePackage())
            }

        override fun getJSMainModuleName(): String = "index"

        override fun getUseDeveloperSupport(): Boolean = BuildConfig.DEBUG

        override val isNewArchEnabled: Boolean = BuildConfig.IS_NEW_ARCHITECTURE_ENABLED
        override val isHermesEnabled: Boolean = BuildConfig.IS_HERMES_ENABLED

        override fun getJSBundleFile(): String? {  
          return HotUpdater.getJSBundleFile(applicationContext)  
        }  
      }

  override val reactHost: ReactHost
    get() = getDefaultReactHost(applicationContext, reactNativeHost)

  override fun onCreate() {
    super.onCreate()
    SoLoader.init(this, OpenSourceMergedSoMapping)
    if (BuildConfig.IS_NEW_ARCHITECTURE_ENABLED) {
      // If you opted-in for the New Architecture, we load the native entry point for this app.
      load()
    }
  }
}

iOS

Objective-C

Swift

ios/<your-app-name>/AppDelegate.mm

#import "AppDelegate.h"
#import <HotUpdater/HotUpdater.h> 
#import <React/RCTBundleURLProvider.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  self.moduleName = @"HotUpdaterExample";
  // You can add your custom initial props in the dictionary below.
  // They will be passed down to the ViewController used by React Native.
  self.initialProps = @{};

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge
{
  return [self bundleURL];
}

- (NSURL *)bundleURL
{
#if DEBUG 
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"]; 
#else 
  return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"]; 
#endif 
  return [HotUpdater bundleURL]; 
}

@end
