Implementations§

Source§

impl SsrEngine

Source

pub fn builder() -> SsrConfigBuilder

Create a new configuration builder

§Example
ⓘ
use rusty_ssr::SsrEngine;

let engine = SsrEngine::builder()
    .bundle_path("ssr-bundle.js")
    .pool_size(4)
    .build_engine()
    .expect("Failed to create engine");
Source

pub fn new(config: SsrConfig) -> SsrResult<Self>

Create a new SSR engine with the given configuration

Source

pub async fn render(&self, url: &str) -> SsrResult<Arc<str>>

Render a URL to HTML

This will first check the cache, and if not found, render via V8.

§Arguments
  • url - The URL path to render (e.g., “/home”, “/products/123”)
§Example
let html = engine.render("/home").await.unwrap();
Source

pub async fn render_with_data( &self, url: &str, data: &str, ) -> SsrResult<Arc<str>>

Render a URL to HTML with custom data

§Arguments
  • url - The URL path to render
  • data - JSON string with data to pass to the render function
Source

pub async fn render_json(&self, url: &str, data: Value) -> SsrResult<Arc<str>>

Render a URL with JSON data (serde_json::Value)

Convenience method that serializes the Value to a string.

§Example
use serde_json::json;

let data = json!({
    "user": { "name": "John" },
    "products": [1, 2, 3]
});
let html = engine.render_json("/products", data).await.unwrap();
Source

pub async fn render_to_html(&self, url: &str) -> SsrResult<String>

Render a URL and inject result into the HTML template

If no template is configured, behaves identically to render(). When a template is set, the V8-rendered fragment is injected into <!--ssr:outlet--> and a complete HTML document is returned.

§Example
// Returns complete HTML document if template is configured
let html = engine.render_to_html("/home").await.unwrap();
// html = "<!doctype html><html>...<div id='root'>...app...</div>...</html>"
Source

pub async fn render_to_html_with_data( &self, url: &str, data: &str, ) -> SsrResult<String>

Render a URL with data and inject into the HTML template

Source

pub fn has_template(&self) -> bool

Check if the HTML template system is enabled

Source

pub async fn render_uncached(&self, url: &str, data: &str) -> SsrResult<String>

Render without caching (always hits V8)

Source

pub async fn render_uncached_json( &self, url: &str, data: Value, ) -> SsrResult<String>

Render without caching with JSON data

Source

pub fn invalidate(&self, url: &str)

Invalidate a single cached URL

Use after content updates for a specific page.

Source

pub fn invalidate_prefix(&self, prefix: &str) -> usize

Invalidate all cached URLs matching a prefix

Example: engine.invalidate_prefix("/products") clears all product pages. Returns the number of removed entries.

Source

pub fn clear_cache(&self)

Clear the SSR cache

Source

pub fn cache_metrics(&self) -> CacheMetrics

Get cache metrics

Source

pub fn worker_count(&self) -> usize

Get the number of active V8 workers

Source

pub fn config(&self) -> &SsrConfig

Get a reference to the configuration

Source

pub fn cache(&self) -> &SsrCache

Get a reference to the cache (if enabled)

Source

pub fn v8_pool(&self) -> &V8Pool

Get a reference to the V8 pool (if enabled)
