typing-speed-test-api/routeService.js

A simple Node.js API to calculate typing speed and accuracy based on user input.

function calculateWPM(text, timeInSeconds) {
    const words = text.trim().split(/\s+/).length;
    return (words / (timeInSeconds / 60)).toFixed(2);
}

function calculateAccuracy(original, typed) {
    const originalWords = original.trim().split(/\s+/);
    const typedWords = typed.trim().split(/\s+/);

    let correct = 0;
    for (let i = 0; i < Math.min(originalWords.length, typedWords.length); i++) {
        if (originalWords[i] === typedWords[i]) {
            correct++;
        }
    }

    const accuracy = (correct / originalWords.length) * 100;
    return accuracy.toFixed(2);
}
