Ways to Use WebAssembly with TypeScript

For developers, developing modern web applications has become critical in terms of performance and user experience. At this point, TypeScript and WebAssembly (Wasm) can be used together. While TypeScript stands out as a type-safe superset of JavaScript, WebAssembly offers high performance, especially for intensive computational operations. In this article, we will examine how to integrate TypeScript and WebAssembly.

What is TypeScript?

TypeScript is a programming language developed by Microsoft that offers static type checking. It allows types to be defined to make JavaScript code more manageable. It provides developers with a safer and less error-prone development experience. Code written in TypeScript is transpiled to JavaScript and runs in browsers. This enables developers to manage larger projects more consistently.

What is WebAssembly?

WebAssembly is a low-level binary format that runs in browsers and enables applications that require high performance. Code written mostly in C, C++, or Rust can be compiled to WebAssembly. WebAssembly allows applications written in these languages to run at high speed on the web and, with the help of a virtual machine, provides fast loading times. Additionally, WebAssembly allows browsers to run code written in languages other than JavaScript.

Integrating TypeScript with WebAssembly

Certain steps should be followed when using TypeScript and WebAssembly together. First, you need to create a module in a language like C/C++ and convert it into the WebAssembly format. Then you can call and use this module within your TypeScript project. Below is a simple example of how to use a WebAssembly module with TypeScript:

// Loading the WebAssembly module
const loadWasmModule = async () => {
    const response = await fetch('module.wasm');
    const buffer = await response.arrayBuffer();
    const module = await WebAssembly.instantiate(buffer);
    return module.instance.exports;
};

// Calling a function from the WebAssembly module
const main = async () => {
    const wasm = await loadWasmModule();
    console.log(wasm.add(5, 3)); // For example, calls the 'add' function found in the C/C++ code.
};

main();

Conclusion

TypeScript and WebAssembly provide a powerful combination for modern web applications. While TypeScript provides developers with a safe development environment, WebAssembly meets performance needs. With proper integration, developers will have the opportunity to build high-quality, performance-oriented applications. By combining these two technologies, we can further advance our experience on the web.
