is-spaghetti-code/index.js

A simple npm package that detects characteristics of spaghetti code by analyzing JavaScript code snippets. It checks for deep nesting and long functions, giving you insights into your code's structure.

function isSpaghettiCode(code) {
    // Check for deep nesting
    const lines = code.split('\n');
    let nestingLevel = 0;
    let maxNestingLevel = 0;

    for (const line of lines) {
        if (line.includes('{')) nestingLevel++;
        if (line.includes('}')) nestingLevel--;
        maxNestingLevel = Math.max(maxNestingLevel, nestingLevel);
    }

    // Check for long functions
    const longFunctionThreshold = 20; // Example threshold for lines in a function
    const functionLines = lines.filter(line => line.includes('function'));
    const longFunctions = functionLines.filter(line => {
        const startIndex = lines.indexOf(line);
        let count = 0;

        for (let i = startIndex; i < lines.length; i++) {
            count++;
            if (lines[i].includes('}')) break;
        }

        return count > longFunctionThreshold;
    });

    return {
        isSpaghetti: maxNestingLevel > 3 || longFunctions.length > 0,
        maxNestingLevel,
        longFunctionCount: longFunctions.length,
    };
}
