axum-htmx
axum-htmx is a small extension library providing extractors for the various
htmx headers within 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
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 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, 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.
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
}
}
