# Leptos Hacker News Example This example creates a basic clone of the Hacker News site. It showcases Leptos' ability to create both a client-side rendered app, and a server side rendered app with hydration, in a single repository ## Client Side Rendering To run it as a Client Side App, you can issue `trunk serve --open` in the root. This will build the entire app into one CSR bundle. Make sure you have trunk installed with `cargo install trunk`. ## Server Side Rendering with cargo-leptos cargo-leptos is now the easiest and most featureful way to build server side rendered apps with hydration. It provides automatic recompilation of client and server code, wasm optimisation, CSS minification, and more! Check out more about it [here](https://github.com/akesson/cargo-leptos) 1. Install cargo-leptos ```bash cargo install --locked cargo-leptos ``` 2. Build the site in watch mode, recompiling on file changes ```bash cargo leptos watch ``` Open browser on [http://localhost:3000/](http://localhost:3000/) 3. When ready to deploy, run ```bash cargo leptos build --release ``` ## Server Side Rendering without cargo-leptos To run it as a server side app with hydration, you'll need to have wasm-pack installed. 0. Edit the `[package.metadata.leptos]` section and set `site-root` to `"."`. You'll also want to change the path of the `` component in the root component to point towards the CSS file in the root. This tells leptos that the WASM/JS files generated by wasm-pack are available at `./pkg` and that the CSS files are no longer processed by cargo-leptos. Building to alternative folders is not supported at this time. You'll also want to edit the call to `get_configuration()` to pass in `Some(Cargo.toml)`, so that Leptos will read the settings instead of cargo-leptos. If you do so, your file/folder names cannot include dashes.. 1. Install wasm-pack ```bash cargo install wasm-pack ``` 2. Build the Webassembly used to hydrate the HTML from the server ```bash wasm-pack build --target=web --debug --no-default-features --features=hydrate ``` 3. Run the server to serve the Webassembly, JS, and HTML ```bash cargo run --no-default-features --features=ssr ```
