## 🚀 Quick Start
### Prerequisites
- Rust 1.70+ with WebAssembly support
- Node.js 18+ and pnpm (for development tools)
- Modern browser with WebAssembly support
### Installation
#### Option 1: From crates.io (Recommended)
Add the crates to your `Cargo.toml`:
```toml
[dependencies]
# Core functionality
flow-rs-core = "0.1.0-beta.1"
# Rendering (choose one or more)
flow-rs-renderer = "0.1.0-beta.1" # Canvas2D renderer
# flow-rs-renderer = { version = "0.1.0-beta.1", features = ["webgl2"] } # WebGL2 renderer
# Framework integration
flow-rs-leptos = "0.1.0-beta.1" # Leptos integration
flow-rs-wasm = "0.1.0-beta.1" # WASM bindings
```
#### Option 2: From source
1. **Clone the repository**:
```bash
git clone https://github.com/cloud-shuttle/flow-rs.git
cd flow-rs
```
2. **Install dependencies**:
```bash
# Install Rust dependencies
cargo build
# Install Node.js dependencies (for development)
pnpm install
```
3. **Run the demo**:
```bash
cd examples/flow-leptos-demo
trunk serve --open
```
### Basic Usage
#### With Leptos Integration
```rust
use flow_rs_leptos::FlowEditor;
use flow_rs_core::{Graph, Node, Position};
use leptos::*;
#[component]
pub fn MyFlowApp() -> impl IntoView {
let graph = RwSignal::new(Graph::new());
view! {
}
}
```
#### Core Usage (Framework Agnostic)
```rust
use flow_rs_core::{Graph, Node, Position, Edge};
use flow_rs_renderer::{Canvas2DRenderer, Renderer};
// Create a graph
let mut graph = Graph::new();
// Add nodes
let node1 = Node::builder("input")
.position(100.0, 100.0)
.size(80.0, 40.0)
.build();
let node2 = Node::builder("process")
.position(300.0, 100.0)
.size(80.0, 40.0)
.build();
graph.add_node(node1);
graph.add_node(node2);
// Add edge
let edge = Edge::builder()
.connect("input", "process")
.build();
graph.add_edge(edge);
// Render with Canvas2D
let renderer = Canvas2DRenderer::new(&canvas)?;
renderer.render_graph_dyn(&graph, &viewport)?;
```
