Let's build a simple Feet & Yards to Meters converter web app using Rust and WebAssembly! This guide provides a streamlined approach.
First, ensure Rust is installed on your system. Download and install it from https://www.php.cn/link/29f81692d9af87c8826aafca8ff5dad3.
Next, create a new Rust project using Cargo:
<code class="language-bash">cargo new yardandfeetconverter</code>
Modify the Cargo.toml file to include the wasm-bindgen dependency and specify the crate type:
<code class="language-toml">[dependencies] wasm-bindgen = "0.2" [lib] crate-type = ["cdylib"]</code>
Navigate to the src directory and rename main.rs to lib.rs. Replace the contents of lib.rs with this conversion logic:
<code class="language-rust">use wasm_bindgen::prelude::*;
#[wasm_bindgen]
pub fn yards_to_meters(yards: f64) -> f64 {
yards * 0.9144
}
#[wasm_bindgen]
pub fn feet_to_meters(feet: f64) -> f64 {
feet * 0.3048
}</code>
Build the WebAssembly module:
<code class="language-bash">wasm-pack build --target web</code>
This generates the necessary web files. Now, create an index.html file in the yardandfeetconverter directory. Paste the following code into index.html:
<code class="language-html"><!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Yard and Feet to Meters Converter</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 0;
padding: 0;
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
background: linear-gradient(to right, #4facfe, #00f2fe);
}
.container {
text-align: center;
background: white;
padding: 2rem;
border-radius: 10px;
box-shadow: 0px 4px 10px rgba(0, 0, 0, 0.1);
}
input, select, button {
margin: 10px;
padding: 10px;
font-size: 16px;
border: 1px solid #ccc;
border-radius: 5px;
}
button {
background-color: #4facfe;
color: white;
cursor: pointer;
}
button:hover {
background-color: #00c4cc;
}
</style>
</head>
<body>
<div class="container">
<h1>Feet & Yards to Meters Converter</h1>
<input type="number" id="value" placeholder="Enter value">
<select id="unit">
<option value="yards">Yards</option>
<option value="feet">Feet</option>
</select>
<button id="convert">Convert</button>
<p id="result"></p>
</div>
<script type="module">
import init, { yards_to_meters, feet_to_meters } from "./pkg/yardandfeetconverter.js";
async function setup() {
await init();
document.getElementById('convert').addEventListener('click', () => {
const value = parseFloat(document.getElementById('value').value);
const type = document.getElementById('unit').value;
let result;
if (type === 'yards') {
result = yards_to_meters(value);
} else {
result = feet_to_meters(value);
}
document.getElementById('result').innerText = `Result: ${result.toFixed(4)} meters`;
});
}
setup();
</script>
</body>
</html></code>
Start a local web server (e.g., using Python's http.server):
<code class="language-bash">python -m http.server</code>
Open your browser and navigate to localhost:8000. You can now convert feet and yards to meters!
