Hero Archipelagos

Modular Dioxus 0.7 WASM island applications that connect to backend services via hero_osis_sdk (structured data) and herofossil-webdav-client (files).

Core Principles

1. Dioxus components — Built with Dioxus 0.7 for Rust-based reactive UI
2. WASM modules — Compiled to WebAssembly, run in the browser
3. hero_osis_sdk consumers — Use the unified SDK client to communicate with hero_osis
4. Embeddable — Imported as library components into host applications (embedded mode)
5. Pure Rust + WASM — No Python servers, no Node.js

Quick Start

# Prerequisites: Rust 1.85+
rustup update stable

# Source environment variables (API keys)
source ~/.config/env.sh

# Start the showcase dev server
make run

# Or directly with Dioxus CLI
cd server && dx serve

Required environment variables:

• GROQ_API_KEY — Groq API key for AI features

Embedding Islands

Islands are standard Dioxus components. Import them as library dependencies:

[dependencies]
hero_archipelagos_core = { path = "path/to/core" }
hero_archipelagos_contacts = { path = "path/to/archipelagos/identity/contacts", default-features = false, features = ["web"] }

use hero_archipelagos_contacts::island::ContactsIslandApp;
use hero_archipelagos_core::IslandContext;

#[component]
fn MyApp() -> Element {
    let context = IslandContext::default();
    rsx! {
        ContactsIslandApp { context: context }
    }
}

Context Configuration

Islands receive configuration via IslandContext:

Field	Description	Example
host	Hero Zero host (service URLs derived from this)	localhost
context_name	Current workspace/context	default
user	User identity (display_name, public_key, avatar_url)	UserIdentity
theme	Theme name	dark
view	Current view / entity ID	list, chat_sid:abc123

Service URLs are derived from the host:

• context.osis_url() → http://{host}:3377 (hero_osis JSON-RPC)
• context.forge_url() → http://{host}:7365 (hero_fossil WebDAV)

SDK Integration

Each island uses hero_osis_sdk with domain-specific features:

// In Cargo.toml
hero_osis_sdk = { workspace = true, features = ["calendar"] }

// In your service
use hero_osis_sdk::calendar::CalendarUnifiedClient;

pub async fn fetch_events(osis_url: &str, context: &str) -> Result<Vec<Event>, String> {
    let client = CalendarUnifiedClient::new(osis_url, context);
    client.event_list().await
}
