[−][src]Macro vial::asset_dir
Vial can serve static files out of an asset directory, complete with ETag support so your browser isn't constantly re-downloading.
To enable this, put all your .js
and .css
and other static
assets into a directory in the root of your project, then
reference them as if the root of your Vial web application was
that asset directory. Next call vial::asset_dir!()
with the path
to your asset directory (maybe assets/
?) before starting your
application with vial::run!
:
If we had a directory structure like this: . ├── README.md ├── assets │ └── img │ ├── banker.png │ └── doctor.png └── src └── main.rs
We could serve our images like so:
vial::routes! { GET "/" => |_| " <p><img src='/img/doctor.png'/></p> <p><img src='/img/banker.png'/></p> "; } fn main() { vial::asset_dir!("assets/"); vial::run!().unwrap(); }
