Building with Next.js and WASM

Today I want to share my experience integrating WebAssembly (WASM) with Next.js. This combination opens up exciting possibilities for high-performance web applications.

Why WebAssembly?

WebAssembly allows you to run code written in languages like Rust, C++, or Go directly in the browser at near-native speeds. This is perfect for:

• Computational tasks - Image processing, data analysis
• Game engines - Physics simulations, rendering
• Legacy code - Porting existing C/C++ libraries

Setting Up WASM in Next.js

Here's a simple Rust function compiled to WASM:

use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn fibonacci(n: u32) -> u32 {
    match n {
        0 => 0,
        1 => 1,
        _ => fibonacci(n - 1) + fibonacci(n - 2),
    }
}

The integration with Next.js is surprisingly smooth, and you can check out the /wasm page on this site to see it in action!

Next Steps

I'm planning to explore more complex WASM use cases, including:

• Image manipulation tools
• Real-time data processing
• Interactive visualizations

Stay tuned for more updates!
