dare-rust-leptos

dare-rust-leptos is a command for Claude Code from dewtech-technologies/dare-method. It costs 0 tokens per session (2,452 once invoked), scanned A, original, MIT.

A development guide for Leptos, a Rust framework for building web interfaces. It helps choose between browser-rendered and server-rendered setups and defines shared-code patterns and task templates.

In plain words
What is it for?
Use it to choose a Leptos setup, configure a workspace, share types between server and browser code, and follow project conventions.
Why use it?
It clarifies architecture choices and avoids common mistakes when combining Rust code that runs in the browser with Rust code that runs on a server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dare-rust-leptos scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/dare-rust-leptos

Guia de desenvolvimento Leptos para projetos DARE. Cobre decisão de variante, idioms obrigatórios, antipatterns, tipos compartilhados e templates de tasks.

Como usar

/dare-rust-leptos                    ← decide variante + configura workspace
/dare-rust-leptos --csr              ← guia específico para CSR + trunk
/dare-rust-leptos --fullstack        ← guia específico para SSR + cargo-leptos
/dare-rust-leptos --shared-types     ← padrão cfg_attr para tipos server + WASM

1. Decisão de variante: CSR vs Fullstack

Critério CSR (trunk) Fullstack (cargo-leptos)
SEO necessário
Time-to-interactive crítico
Dashboard interno / admin
Backend Axum existente indiferente ✅ integração direta
Simplicidade de deploy ✅ arquivos estáticos (CDN) ⚠️ binário Axum
Server functions (#[server]) ❌ não existe

Regra de ouro:

  • Se o projeto vive atrás de login e SEO não importa → CSR
  • Se precisa de SEO, carregamento inicial rápido, ou server functions → Fullstack
  • Se já tem rust-axum como backend no monorepo → Fullstack (workspace unificado)

2. Ferramentas — nunca misturar

Variante Build Dev server Test
CSR trunk build --release trunk serve cargo test --workspace
Fullstack cargo leptos build --release cargo leptos watch cargo test --workspace

⚠️ cargo leptos test não existe. Use sempre cargo test --workspace. ⚠️ Não use trunk para fullstack nem cargo leptos para CSR — ferramentas erradas para o target errado.


3. Idioms obrigatórios Leptos 0.7

Estado reativo

// ✅ Fine-grained signals — só re-renderiza o que usa o signal
let (count, set_count) = signal(0);
let doubled = move || count.get() * 2;  // derived (memo inline)

// Para estado complexo ou compartilhado entre componentes:
let count = RwSignal::new(0);  // read + write em um só

Dados assíncronos

// ✅ Resource — fetch declarativo, integra com Suspense
let user = Resource::new(|| user_id(), |id| async move { fetch_user(id).await });

// ✅ Suspense — loading state automático
view! {
    <Suspense fallback=|| view! { <p>"Loading..."</p> }>
        {move || user.get().map(|u| view! { <p>{u.name}</p> })}
    </Suspense>
}

// ❌ Nunca — Effect que faz fetch (re-executa em todo render)
Effect::new(move |_| { spawn_local(async { fetch_user(id).await }); });

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
