# axum-htmx
|
|
|
|
`axum-htmx` is a small extension library providing extractors for the various
|
|
[htmx](https://htmx.org/) headers within [axum](https://github.com/tokio-rs/axum).
|
|
|
|
__This crate is current a work-in-progress. There are many missing header implementations, and it builds against the upcoming, unreleased branch for `axum`.__
|
|
|
|
## Usage
|
|
|
|
```toml
|
|
axum-htmx = { git = "https://github.com/robertwayne/axum-htmx", branch = "main" }
|
|
```
|
|
|
|
## Examples
|
|
|
|
In this example, we'll look for the `HX-Boosted` header, which is set when applying the [hx-boost](https://htmx.org/attributes/hx-boost/) attribute to an element. In our case, we'll use it to determine what kind of response we send.
|
|
|
|
When is this useful? When using a templating engine, like [minijinja](https://github.com/mitsuhiko/minijinja), it is common to extend different templates from a `_base.html` template. However, HTMX works by sending partial responses, so extending our `_base.html` would result in lots of extra data being sent over the wire.
|
|
|
|
If we wanted to swap between pages, we would need to support both full template responses and partial responses _(as the page can be accessed directly or through a boosted anchor)_, so we look for the `HX-Boosted` header and extend from a `_partial.html` template instead.
|
|
|
|
```rs
|
|
async fn get_index(HxBoosted(boosted): HxBoosted) -> impl IntoResponse {
|
|
if boosted {
|
|
// Send a template extending from _partial.html
|
|
} else {
|
|
// Send a template extending from _base.html
|
|
}
|
|
}
|
|
```
