Documentation

Hearth renders the initial view on the server and compiles browser interactions to JavaScript. Start with a page, then add scoped tables and local queries.

Start here

1. Getting started: install the CLI and render a first page.
2. Views: write markup and reactive expressions in Rust.
3. Server-only table fields: declare a table and choose what reaches the browser.
4. Persistence and sync: learn what is cached locally and what the server checks.
