πŸš€ Quick Start

Installation

cargo add leptos-next-metadata

Basic Usage

Using Components (Recommended)

use leptos::*;
use leptos_next_metadata::prelude::*;

#[component]
fn MyPage() -> impl IntoView {
    view! {
        <Html lang="en" dir="ltr" />
        <Body class="my-app" lang="en" />
        <MetaTags />
        <EnhancedTitle
            text="My Awesome Page"
            template="{} | My Site"
        />
        <HashedStylesheet
            options=leptos::prelude::LeptosOptions::builder()
                .output_name("my-app")
                .build()
        />

        <div>
            <h1>"Welcome to My Page"</h1>
            <p>"This page uses our new metadata components!"</p>
        </div>
    }
}

Using Macros (Traditional)

use leptos::*;
use leptos_next_metadata::prelude::*;

#[component]
fn MyPage() -> impl IntoView {
    metadata! {
        title: "My Awesome Page",
        description: "This is a fantastic page with great content",
        keywords: ["rust", "leptos", "metadata", "seo"],
        og_type: "website",
        og_image: "/og-image.jpg",
    }

    view! {
        <div>
            <h1>"Welcome to My Page"</h1>
            <p>"This page has automatic metadata generation!"</p>
        </div>
    }
}

Dynamic Metadata

use leptos_next_metadata_macros::generate_metadata;

#[generate_metadata]
fn get_metadata() -> Metadata {
    Metadata {
        title: Some(Title::Static("Dynamic Page".into())),
        description: Some("Generated description".into()),
        og_type: Some("article".into()),
        ..Default::default()
    }
}

Competitive Analysis

use leptos_next_metadata::competitive_analysis::*;

// Create competitive analysis service
let mut service = CompetitiveAnalysisService::new();

// Add our capabilities
let our_capability = Capability::new(
    "SSR Performance".to_string(),
    "Server-side rendering with Rust".to_string(),
    ImplementationType::Rust,
    PerformanceMetrics::new(Some(2000.0), Some(25.0), Some(128.0), Some(30.0)),
    ClientValue::new(9.0, 8.5, 9.5, 9.0, 9.5),
);
service.add_our_capability(our_capability);

// Add competitor
let competitor = Competitor::new(
    "Next.js".to_string(),
    CompetitorCategory::WebFramework,
    vec![],
    vec!["Large ecosystem".to_string()],
    vec!["JavaScript performance".to_string()],
    25.5,
);
service.add_competitor(competitor);

// Analyze competitor
if let Some(analysis) = service.analyze_competitor("Next.js") {
    println!("Gap Analysis: {:?}", analysis.gap_analysis);
    println!("Recommendations: {:?}", analysis.recommendations);
    println!("Our Advantages: {:?}", analysis.competitive_advantage);
}
