AxI Itinerary is a web application designed as a travel itinerary planner and guidebook, helping users organize and manage their trips effectively.

This project uses a modern web architecture with the following components:

• Cloudflare Workers: Serverless edge computing for API endpoints and data processing.
• D1 Database: Fast, SQLite-compatible database for storing itinerary data.
• Svelte: Lightweight frontend framework for responsive UI.
• Rust (WebAssembly): High-performance client-side logic for complex calculations like itinerary optimization and data manipulation.

• Rust's Role: Rust compiles to WebAssembly, enabling fast, safe execution of heavy computations (e.g., route planning, budget calculations) directly in the browser without server round-trips.
• Backend Structure: The "backend" is split into two parts:
  • Server-side: Cloudflare Workers handle API routes and database interactions.
  • Client-side: Rust WASM library provides performant logic for the frontend.
• Tech Choices: Cloudflare Workers offer global edge deployment with low latency. D1 ensures quick queries. Svelte keeps the UI snappy. Rust WASM avoids JavaScript performance bottlenecks for CPU-intensive tasks.

• Node.js (version 18 or higher)
• pnpm
• Rust (with wasm-pack)
• Cloudflare Wrangler CLI

1. Clone the repository.

   git clone https://github.com/soranjiro/AxI-itinerary.git
   cd AxI-itinerary

2. Install dependencies.

   pnpm install

3. Add the Rust WASM target (first time only).

   rustup target add wasm32-unknown-unknown

4. Install wasm-pack (first time only).

   cargo install wasm-pack

Use D1 Database locally.

1. Create the D1 database (first time only).

   wrangler d1 create axi-itinerary-db --local

2. Apply migrations.

   wrangler d1 migrations apply axi-itinerary-db --local

3. Check migrations.

   wrangler d1 migrations list axi-itinerary-db --local

4. Verify database contents (optional).

   wrangler d1 execute axi-itinerary-db --local --command "SELECT name FROM sqlite_master WHERE type='table';"
   wrangler d1 execute axi-itinerary-db --local --command "SELECT * FROM users;"

make dev

This builds the WASM library and starts the local Cloudflare Workers development server. Access the app at http://localhost:8787 in your browser.
