  • Spanish
• App setup script: setup-apps.sh
  • Initializes Ionic Capacitor
  • Sets up ios
  • Sets up android
  • Creates icons (see make-icons.sh)
  • Copies icons for ios/android (see update-app-icons.sh)
• Icon build system
  • make-icons.sh creates all icons from a base icon svg file icon.svg
  • update-app-icons.sh copies icons needed for ios and android app versions

Development Targets

• Web Dev: npm run dev or ./dev.sh
• iOS: npm run ios
• iOS with instant reload: npm run ios-reload
  • requires npm run dev server running on port 5172
• Android: npm run android
• Android with instant reload npm run android-reload
  • requires npm run dev server running on port 5172

Deploy Targets

• Static Web Site: npm run build
• iOS: npm run ios
• Android npm run android
• Desktop Releases:
  • Push to release branch
    • git checkout -B release
    • git merge main
    • git push
  • This will trigger Github Actions (./.github/*.yaml) to automatically build with the following releases with Tauri:
    • MacOS Intel (x86_64)
    • MacOS Apple Silicon (ARM)
    • Windows x86_64
    • Windows ARM
    • Ubuntu/Linux x86_64
    • Ubuntu/Linux ARM

Setup / Quickstart

Set Up Keys

• Server URL and ANON_KEY are encrypted (for obfuscation)
  • cp .keys.json.sample .keys.json
  • enter your URL and ANON_KEY in .keys.json
  • make sure Deno 2.0 is installed
  • run: ./lock-up-keys.sh OR deno run --allow-read --allow-write lock-up-keys.deno.ts
• Copy keys to Github Secrets (necessary to run Github Actions to create Desktop versions with Tauri)
  • make sure gh (Github Command Line) is installed
  • run gh secret set -f .env

Set up Supabase Edge Functions

• make sure the Supabase CLI is installed
• run: supabase init from the root of your project
  • a file supabase/config.toml will be created
  • by default this file is excluded from source control
  • you can add it source control by commenting it out in supabase/.gitignore
• run: supabase link from the root of your project
• setup keys
  • create the .env file: cp supabase/.env-sample supabase/.env
  • set your keys in the supabase/.env file:
    • SEND_EMAIL_HOOK_SECRET=your_hook_secret
      • Set up auth hook here: Supabase Auth Hooks
      • Set up auth hook for your edge function: send-email TODO
    • MAILGUN_API_KEY=your_mailgun_api_key
    • MAILGUN_DOMAIN=your_mailgun_domain

Deploy Supabase Edge Functions

• from the root of your project, run:
  • supabase functions deploy send-email
  • supabase functions deploy server_function

Utility Scripts

• dev.sh: run the local development server and open in browser
• deploy-cloudflare.sh: build and deploy to Cloudflare Pages
• dump_schema.sh: dump the database schema from Supabase to ./data/schema.sql
• fix_macos_app.sh: to run a downloaded MacOS app version that's unsigned, run fix_macos_app.sh <app-name> such as fix_macos_app.sh svelte5-template_macos.app. This runs xattr -cr svelte5-template_macos.app to enable the app to be run even though it's not signed.
• generate-types.sh: generate typescript types from Supabase to ./src/lib/types/database.types.ts
• lock-up-keys.sh: encrypt keys in .keys.json and write them to encrypted values in .env
• make-icons.sh: generate all app icons from the original icon svg in ./static/icon.svg
• setup-apps.sh: initialize Capacitor apps for iOS and Android and create all app icons
• shadcn-add-component.sh: add a new component from the shadcn-svelte library into the project
• update-app-icons.sh: copy all app icons for iOS and Android
