About this Crate
This crate offers some localization tools to be used with Axum.
Basic usage
You can use this crate to extract a language identifier (ex en-US
) from a request.
If the mode is set to RedirectMode::NoRedirect
, the Accept-Language header is used to find the users preferred language. If the mode is set to either RedirectMode::RedirectToFullLocaleSubPath
or RedirectMode::RedirectToLanguageSubPath
, the user will be redirected to a sub-path based on their Accept-Language headers, to to the default language if not supported.
use unic_langid::{langid, LanguageIdentifier};
use axum::Extension;
pub const ENGLISH: LanguageIdentifier = langid!("en");
pub const JAPANESE: LanguageIdentifier = langid!("ja");
let router = axum::Router::new()
.route("/lists", get(|Extension(lang): Extension<LanguageIdentifier>|
async move {
Html(format!("Your language is: {}", lang.to_string()))
}))
.layer(axum_l18n::LanguageIdentifierExtractorLayer::new(
ENGLISH,
vec![ENGLISH, JAPANESE],
axum_l18n::RedirectMode::NoRedirect,
));
Features
fluent
Enabling fluent allows you to use the fluent Localizer to add bundles for translation.
See fluent-rs for details about fluent and rust.
Usage
use unic_langid::{langid, LanguageIdentifier};
use axum_l18n::Localizer;
pub const ENGLISH: LanguageIdentifier = langid!("en");
pub const JAPANESE: LanguageIdentifier = langid!("ja");
let mut localizer = Localizer::new();
localizer
.add_bundle(JAPANESE, &["locales/ja/main.ftl", "locales/ja/login.ftl"])
.unwrap();
localizer
.add_bundle(ENGLISH, &["locales/en/main.ftl", "locales/en/login.ftl"])
.unwrap();
tera
Enabling the tera feature allows you to use the fluent translations inside tera templates.
See tera for more information on tera.
Usage
Initialization:
use tera::Tera;
let mut tera = Tera::new("src/views/templates/**/*").expect("tera parsing error");
let mut localizer = Localizer::new();
localizer
.add_bundle(ENGLISH, &["locales/en/main.ftl", "locales/en/login.ftl"])
.unwrap();
tera.register_function("fluent", localizer);
Axum handler:
#[derive(Clone)]
struct ViewRouterState {
pool: mysql_async::Pool,
tera: Arc<tera::Tera>,
}
async fn lists_view(
State(state): State<ViewRouterState>,
Extension(lang): Extension<LanguageIdentifier>,
) -> axum::response::Response {
let lists: Vec<String> = List::paginate(&state.pool, claim.sub)
.await.unwrap();
let mut ctx = Context::new();
ctx.insert("lists", &lists);
ctx.insert("lang", &lang);
let html = state.tera.render("lists.html", &ctx).unwrap();
Html(html).into_response()
}
In tera template:
<label for="family-id">{{ fluent(key="list-family", lang=lang) }}</label>
<select name="family-id" id="family-id">
{% for family in families %}
<option value="{{ family.family_id }}">{{ family.family_name }}</option>
{% endfor %}
</select>
