Leptos Frontend in Rust: Signals, Router, and WASM - Building a Real UI (Gupti Ep 6)
Episode 6 of the Gupti series from Aarambh Dev Hub. We build the frontend in Rust.
Leptos compiles to WebAssembly and runs in the browser. Same language as the backend. Same type safety. Same tooling.
What you will learn:
Why Leptos and WASM for frontend development
Project setup with Trunk build tool
App structure with leptos_router (3 routes)
Typed API client with gloo_net
Create page: form, validation, submission
Created page: shareable link, copy button
Reveal page: loading, display, countdown, burn notice
Key Leptos concepts:
Signals for reactive state (like React hooks)
Components and props
Two-way binding for forms
Client-side routing
Async actions with create_action
Dependencies explained:
leptos (core framework)
leptos_router (routing)
gloo_net (HTTP fetch)
gloo_timers (countdown)
web_sys (browser APIs)
After this episode, the app works end to end. Create secret, get link, reveal once.
