This repository contains a template for a fullstack Rust application. It is based on these technologies:

• leptos for the frontend, including:
  • reqwest for HTTP requests
  • serde and serde_json for JSON serialization
  • anyhow to easily handle errors
• rocket for the backend, including:
  • serde and serde_json for JSON serialization

Additionally, the project contains a shared library that is used by both the frontend and the backend. In this library you can define shared data structures, like data transfer objects, and functions. It also uses serde and serde_json for JSON serialization.

The whole project it configured as one workspace containing all three projects.

The frontend uses nightly features and compiles to WebAssembly, so you have to install the nightly toolchain and the wasm target, if you haven't already.

rustup toolchain install nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

The same commands can be used to update the toolchain to the newest version.

The frontend uses nightly features, so you have to set the workspace to nightly build.

rustup override set nightly

You have to start the frontend and the backend separately.

Go into the backend directory and run the following command:

cd backend
cargo run

It will launch the backend using the Rocket library. The default port is 8000.

If you want hot reloading, you can run the backend with the following command:

cd backend
cargo watch -x run

Go into the frontend directory and run the following command:

cd frontend
trunk serve

It will launch the development server for the frontend using the leptos library. The default port is 8080. In the file Trunk.toml, the proxy for the dev server is configured such that every request to /api is forwarded to http://localhost:8000/api.

The frontend is run with hot reload.

Open the browser and go to http://localhost:8080. You should see the text "Hello from backend" that is fetched from the backend via an HTTP request.
