Trunk is a WASM web application bundler for Rust. Trunk uses a simple, optional-config pattern for building & bundling WASM, JS snippets & other assets (images, css, scss) via a source HTML file.
# Getting Started
## Install
First, install Trunk via one of the following options.
### Plain cargo
Download the sources and build them yourself:
```bash
cargo install --locked trunk
```
You can also toggle some features using the `--features` flag:
rustls (default)
Use rustls for client and server sockets
native-tls
Enable the use of the system native TLS stack for client sockets, and `openssl` for server sockets
update_check (default)
Enable the update check on startup
**NOTE:** If both `rustls` and `native-tls` are enabled, `rustls` will be used. You can disable the default `rustls` using
`--no-default-features`.
### Cargo binstall
You can download a released binary from GitHub releases through [`binstall`](https://github.com/cargo-bins/cargo-binstall).
```bash
cargo binstall trunk
```
### GitHub release download
Fetch and unpack a released binary from the [release page](https://github.com/trunk-rs/trunk/releases).
For example (be sure to check for the most recent version):
```bash
wget -qO- https://github.com/trunk-rs/trunk/releases/download/0.17.10/trunk-x86_64-unknown-linux-gnu.tar.gz | tar -xzf-
```
### NixOS
```bash
nix-env -i trunk
```
### Brew
```bash
brew install trunk
```
## Additional tools
Any additional tools like `wasm-bindgen` and `wasm-opt` are automatically downloaded and managed by trunk. Therefore, no further steps required 🎉.
**Note:** Until `wasm-bindgen` has pre-built binaries for Apple M1, M1 users will need to install `wasm-bindgen` manually.
```bash
cargo install --locked wasm-bindgen-cli
```
## App Setup
Any `wasm-bindgen`-based framework will work with Trunk. If you're new to [frontend development in Rust][], [Yew][] and [Leptos][] are two popular options.

[Yew]: https://yew.rs/
[Leptos]: https://leptos.dev/
The easiest way to ensure that your application launches properly is to [setup your app as an executable][cargo-layout] with a standard `main` function:
[cargo-layout]: https://doc.rust-lang.org/cargo/guide/project-layout.html
```rust
fn main() {
// ... your app setup code here ...
}
```
Trunk uses a source HTML file to drive all asset building and bundling. Trunk also uses the official [dart-sass](https://github.com/sass/dart-sass), so let's get started with the following example. Copy this HTML to the root of your project's repo as `index.html`:
```html
```
`trunk build` will produce the following HTML at `dist/index.html`, along with the compiled scss, WASM & the JS loader for the WASM:
```html
```
The contents of your `dist` dir are now ready to be served on the web.
