Hello, I'm trying to deploy my realworld project in shuttle. Locally with

cargo shuttle run

works well. The deploy works fine, no errors. But when I try to access my project, it hangs forever. This is my project source: https://github.com/Bechma/realworld-actix-fullstack and this is my page: https://realworld-fullstack.shuttleapp.rs/ Making a request with:

curl -vvv https://realworld-fullstack.shuttleapp.rs

And here hangs... In the logs, I see sqlx queries, debug globset from Tera but nothing from actix_web of successful request

Hmm, this might be because you're using dotenv, could you try replacing it with shuttle-secrets?

Adding

#[shuttle_static_folder::StaticFolder(folder = "templates")] static_folder: std::path::PathBuf,

doesn't solve the issue, I still see :

2022-12-26T14:17:17.833563037Z DEBUG globset: glob converted to regex: Glob { glob: "templates/**/*", re: "(?-u)^templates(?:/|/.*/)[^/]*$", opts: GlobOptions { case_insensitive: false, literal_separator: true, backslash_escape: true }, tokens: Tokens([Literal('t'), Literal('e'), Literal('m'), Literal('p'), Literal('l'), Literal('a'), Literal('t'), Literal('e'), Literal('s'), RecursiveZeroOrMore, ZeroOrMore]) }

So nothing changed(this is the expected log messages anyway). BTW: the link you provided have a link pointing to https://github.com/shuttle-hq/examples/tree/main/axum/websocket instead of https://github.com/shuttle-hq/examples/tree/main/axum/static-files

Nice! 🥳

Hey @enough-exabyte-92081, glad you got it working. Mind explaining a bit more what the issue and fix was? We would ideally like this experience to be as painless as possible

Sure, so the situation was the following:

rust
lazy_static! {
    static ref TEMPLATES: Tera = {
        let mut tera = match Tera::new("templates/**/*") {
            Ok(t) => t,
            Err(e) => {
                println!("Template parsing error(s): {}", e);
                ::std::process::exit(1);
            }
        };
        tera.autoescape_on(vec!["j2"]);
        tera
    };
}

I had something like this in my templates module. This is incompatible with the shuttle initialization, as the parse/loading of templates is done at runtime(not static). So my tweak was:

rust
lazy_static::lazy_static! {
    pub static ref TEMPLATES: once_cell::sync::OnceCell<tera::Tera> = once_cell::sync::OnceCell::new();
}

So I had to declare the static reference as

OnceCell

. This way, I can initialize it during main() for local development or in lib during shuttle startup. What I'm not very happy is with the initialization in the tests, as it doesn't behave the way I want... Maybe I'm doing something wrong but at least it loads the templates and got the result expected.

I see. If you are now using

OnceCell

, then you should be able to drop the

lazy_static

, right?

I followed the recommended approach in Tera docs, this is why I put it like this. I also tried to reduce the

app_state

because in other project I had huge problems with a memory leak(similar to this issue https://github.com/actix/actix-web/issues/1780 ), and when I dropped the

app_state

from my code, the leak was gone... I'll try to retest it in the future, but I was afraid this time. You are right, I don't need

lazy_static

anymore 😮
