Function localizerFor

localizerFor(ctx: IRequestContext): ILocalizer
Returns the localizer for a request's resolved locale.

Resolves the service under CAPABILITIES.LOCALIZATION and binds it to ctx.request.locale. A request with no locale (a path the middleware excludes, or a reader running before priority 45) gets the default locale rather than an error. A locale an application installed with replaceLocale that is not itself supported is negotiated against the supported set (de-AT → de), falling back to the default — a stored preference never turns into a 500.
Parameters
- ctx: IRequestContext
  The request context
Returns ILocalizer
A localizer bound to the request's locale
Throws
If no provider of CAPABILITIES.LOCALIZATION is registered
Example
```
app.router.get('/', (ctx) => {
  const { t } = localizerFor(ctx);
  return ctx.response.text(t('greeting', { name: 'Ada' }));
});
```
