Leptos Starter Template

This is a template for use with the Leptos web framework and the cargo-leptos tool.

Creating your template repo

If you don't have cargo-leptos installed you can install it with

cargo install cargo-leptos --locked

Then run

cargo leptos new --git leptos-rs/start

to generate a new project template (you will be prompted to enter a project name).

cd {projectname}

to go to your newly created project.

Of course, you should explore around the project structure, but the best place to start with your application code is in src/app.rs.

Running your project

cargo leptos watch
By default, you can access your local project at http://localhost:3000

Installing Additional Tools

By default, cargo-leptos uses nightly Rust, cargo-generate, and sass. If you run into any trouble, you may need to install one or more of these tools.

1. rustup toolchain install nightly --allow-downgrade - make sure you have Rust nightly
2. rustup target add wasm32-unknown-unknown - add the ability to compile Rust to WebAssembly
3. cargo install cargo-generate - install cargo-generate binary (should be installed automatically in future)
4. npm install -g sass - install dart-sass (should be optional in future)

Executing a Server on a Remote Machine Without the Toolchain

After running a cargo leptos build --release the minimum files needed are:

1. The server binary located in target/server/release
2. The site directory and all files within located in target/site

Copy these files to your remote server. The directory structure should be:

leptos_start
site/

Set the following environment variables (updating for your project as needed):

export LEPTOS_OUTPUT_NAME="leptos_start"
export LEPTOS_SITE_ROOT="site"
export LEPTOS_SITE_PKG_DIR="pkg"
export LEPTOS_SITE_ADDR="127.0.0.1:3000"
export LEPTOS_RELOAD_PORT="3001"

Finally, run the server binary.

Notes about CSR and Trunk:

Although it is not recommended, you can also run your project without server integration using the feature csr and trunk serve:

trunk serve --open --features csr

This may be useful for integrating external tools which require a static site, e.g. tauri.
