Rust Chatbot

I'm following along with this tutorial. It's outdated, as mentioned in the comments by the author, and that's without mentioning that the whole LLM field has moved forward an epoch if you've blinked. Still, I figure it'll be good for trying to get more of a feel for Rust, and if I'm feeling particularly daring, maybe I'll even try to update some stuff on the fly.

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.
