In this architecture, Astro is responsible for static site generation and asset optimization, creating pre-rendered HTML, CSS, and JavaScript files for high performance and efficient delivery. Go Fiber handles dynamic data processing, API integration, and serving the static files, providing real-time data updates and efficient server-side routing and middleware management. This combination leverages the strengths of both technologies to create a performant and scalable web application.
Here's a step-by-step guide to creating a web application using the Hybrid Rendering Architecture with Astro and Go Fiber.
npm create astro@latest cd my-astro-site
Create src/pages/index.astro:
--- export const prerender = true; --- <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>{Astro.props.title}</title> <link rel="stylesheet" href="/assets/style.css"> </head> <body> <h1>{Astro.props.title}</h1> <p>{Astro.props.message}</p> <script src="/assets/script.js"></script> </body> </html>
Create src/assets/style.css:
body { font-family: Arial, sans-serif; background-color: #f0f0f0; margin: 0; padding: 20px; }
Create src/assets/script.js:
document.addEventListener('DOMContentLoaded', () => { console.log('Astro and Go Fiber working together!'); });
npm run build
go mod init mysite go get github.com/gofiber/fiber/v2
Create main.go:
package main import ( "log" "github.com/gofiber/fiber/v2" "path/filepath" "encoding/json" "io/ioutil" "bytes" "os/exec" "net/http" ) // Function to render Astro template func renderAstroTemplate(templatePath string, data map[string]interface{}) (string, error) { cmd := exec.Command("astro", "build", "--input", templatePath) // Pass data to template via stdin jsonData, err := json.Marshal(data) if err != nil { return "", err } cmd.Stdin = bytes.NewBuffer(jsonData) output, err := cmd.CombinedOutput() if err != nil { return "", fmt.Errorf("failed to execute astro build: %s", string(output)) } // Read generated file outputPath := filepath.Join("dist", "index.html") content, err := ioutil.ReadFile(outputPath) if err != nil { return "", err } return string(content), nil } func main() { app := fiber.New() // Serve static files from the dist directory app.Static("/", "./my-astro-site/dist") app.Get("/", func(c *fiber.Ctx) error { data := map[string]interface{}{ "title": "My Astro Site", "message": "Welcome to my site built with Astro and Go Fiber!", } htmlContent, err := renderAstroTemplate("./my-astro-site/src/pages/index.astro", data) if err != nil { return c.Status(http.StatusInternalServerError).SendString(err.Error()) } return c.Type("html").SendString(htmlContent) }) log.Fatal(app.Listen(":3000")) }
go run main.go
Open your browser and navigate to http://localhost:3000.
In this example, Astro handles the static site generation, creating optimized HTML, CSS, and JavaScript files. Go Fiber serves these static files and dynamically injects data into the templates, allowing for real-time data updates. This hybrid rendering architecture leverages the strengths of both technologies to create a performant and scalable web application.
