Leptos Hacker News Example with Axum

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. This repo differs from the main Hacker News example by using Axum as it's server.

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

1. Install cargo-leptos

cargo install --locked cargo-leptos

2. Build the site in watch mode, recompiling on file changes

cargo leptos watch

3. When ready to deploy, run

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 "pkg". You'll also want to change the path of the <StyleSheet / > 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.
1. Install wasm-pack

cargo install wasm-pack

2. Build the Webassembly used to hydrate the HTML from the server

wasm-pack build --target=web --debug --no-default-features --features=hydrate

3. Run the server to serve the Webassembly, JS, and HTML

cargo run --no-default-features --features=ssr
