Angular Example

This project is a note-taking app template built with Angular, TypeScript, and Tailwind CSS, designed to demonstrate integration with Juno for app development. It showcases authentication, data storage, and file storage using Juno's Satellite container.

You can scaffold it using the following command, or browse the source code:

npm create juno@latest -- --template angular-example

Key Features

• Juno Integration: Uses Juno's Satellite for authentication, Datastore, and Storage.
• Authentication: Login/logout flow.
• Notes Collection: Users can create, view, and delete notes (text, with optional file URL).
• Images Collection: Supports file storage for images.
• Responsive UI: Built with Tailwind CSS for modern styling.
• Banner: Warns if the Satellite is not configured for local development.

---

Main Components

• app.component.ts: Main Angular component, bootstraps the app and layout.
• components/: Contains UI and logic for authentication, notes table, modal, banner, etc.
• services/: Angular services for interacting with Juno and managing app state.
• types/note.ts: TypeScript interface for notes.

---

Data Structure

• Note (src/app/types/note.ts):

  export interface Note {
    text: string;
    url?: string;
  }

How to Run

1. Install dependencies:

npm install

2. Start Juno local emulator:

important

Requires the Juno CLI to be available npm i -g @junobuild/cli

juno dev start

3. Create a Satellite for local dev:

   • Visit http://localhost:5866 and follow the instructions.
   • Update src/environments/environment.ts with your Satellite ID.

4. Create required collections:

• notes in Datastore: http://localhost:5866/datastore
• images in Storage: http://localhost:5866/storage

5. Start the frontend dev server (in a separate terminal):

npm run dev

---

Juno-Specific Configuration

• juno.config.mjs: Defines Satellite IDs for development/production, build source, and predeploy steps. See the Configuration reference for details.
• src/environments/environment.ts: Contains the Satellite ID for local development.
• src/environments/environment.prod.ts: Contains the Satellite ID for production.

---

Production Deployment

• Create a Satellite on the Juno Console for mainnet.
• Update src/environments/environment.prod.ts and juno.config.mjs with the production Satellite ID.
• Build and deploy:

  npm run build
  juno deploy

---

Notes

• The app is intended as a starting point for Juno-based projects.
• All logic is in TypeScript and Angular components/services.
• The app is fully client-side (Server Side Rendering is not supported yet) and interacts with Juno via the Satellite container.
