The Ecosystem

Three powerful libraries working together to make web development in Vala a joy

Astralis

The high-performance web server foundation. Astralis provides the HTTP server, routing, compression, and static file serving that powers Spry applications.

HTTP Server Routing Compression Fast Resources Middleware
Vala 
var app = new WebApplication(8080);
app.use_compression();
app.add_endpoint(
    new EndpointRoute("/api")
);
app.run();

Inversion

A lightweight dependency injection container. Inversion manages your services, stores, and component lifecycles with elegant IoC patterns.

IoC Container DI Lifecycles Factories Modules
Vala 
// Register services
container.add_singleton();
container.add_scoped();
container.add_transient();

// Inject anywhere
var db = inject();

Spry

The component-based web framework. Spry brings reactive templates, HTMX integration, and a delightful developer experience to Vala web development.

Components HTMX Templates Outlets Actions
Vala 
class MyComponent : Component {
    public override string markup {
        owned get {
            return "

                
            
";
        }
    }
}

🔗 How They Work Together

The three libraries form a complete stack for building web applications:

1

Astralis Handles HTTP

Receives requests, routes them to the right handler, and sends responses with compression.

2

Inversion Manages Dependencies

Creates and injects services, stores, and components with the right lifecycle.

3

Spry Renders UI

Components handle requests, render templates, and respond with HTML for HTMX.
