Struct SpaMiddleware 

pub struct SpaMiddleware { /* private fields */ }

SPA static file middleware.

• Matches /{filename} against local filesystem
• Serves files with auto-detected MIME types
• Falls back to index.html for unknown paths (SPA routing)
• Only handles GET requests; non-GET passes through silently

Implementations

impl SpaMiddleware

pub fn new(root: impl Into<PathBuf>) -> Self

Create a new SPA middleware with default index “index.html”.

The root path is resolved relative to the current working directory. If the directory doesn’t exist at that path, the middleware searches upward through ancestor directories and their immediate subdirectories, matching the strategy used by [config::load_appsettings].

pub fn with_index(root: impl Into<PathBuf>, index: impl Into<String>) -> Self

Create a new SPA middleware with a custom index file name.

Trait Implementations

impl IMiddleware for SpaMiddleware

fn invoke<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 mut dyn IHttpContext, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Process an HTTP request (before hook).

fn after<'life0, 'life1, 'async_trait>( &'life0 self, _ctx: &'life1 mut dyn IHttpContext, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called after the final handler has executed.
