Unlock the Power of WebAssembly
Are you tired of dealing with the limitations of traditional web development? Do you dream of creating high-performance, interactive applications that rival their native counterparts? Look no further than WebAssembly, the revolutionary technology that’s changing the game.
What is WebAssembly?
WebAssembly is a low-level, assembly-like language that enables you to compile your C/C++ code into a compact binary format. This format can be executed with near-native performance, providing a seamless experience for users. In essence, WebAssembly acts as a compilation target for languages like C/C++ and Rust, allowing them to run on the web.
The Benefits of WebAssembly
With WebAssembly, you can:
- Outsource performance-intensive tasks: Offload computationally heavy tasks, such as 3D games, virtual reality, and computer vision, to C/C++ or Rust-like performant languages.
- Integrate legacy libraries: Seamlessly incorporate amazing legacy libraries written in C/C++ into your web application.
- Create lightning-fast applications: Build super-fast and beautiful applications, like Google Earth, that leave users in awe.
Building a Tic-Tac-Toe Game with WebAssembly
Let’s put WebAssembly into action by creating a simple tic-tac-toe game. We’ll use Emscripten, a powerful tool that converts our C++ code into a.wasm file, which can then be imported into our web application.
Game Logic in C++
Our game logic is written in the tic_tac_toe.cpp file, where we import the necessary Emscripten libraries and define our tic_tac_toe() function. This function includes the main logic for our game, including computing which player has won, calculating if there’s no winner, and indicating pending moves.
Transpiling the.cpp File to.wasm and.js
Once our .cpp file is ready, we transpile it to a .wasm file and a .js file using Emscripten. The .js file includes the glue code necessary for loading our C++ function and exposing it as a module that can be imported.
Calling C++ Functions in Our Web App
We then prepare our JavaScript code, which calls our tic_tac_toe() function. We declare the variables that hold the initial values of the board and use the onRuntimeInitialized callback to ensure that our function is called only when the runtime is ready.
The Final Result
And that’s it! Our first game in WebAssembly is ready. You can check out the final game code here.
