Introducing sast-scan: A Lightweight SAST npm Package for JavaScript Security

?️ Secure Your JavaScript Code with Ease.

Security is a critical aspect of software development, and as developers, we should all strive to ensure our applications are free of vulnerabilities. Introducing sast-scan, a simple yet powerful static application security testing (SAST) tool designed to scan JavaScript codebases for vulnerabilities.

In this post, I will walk you through what sast-scan is, how it works, and how it can help you maintain more secure code!

What is sast-scan?

SAST-scan is a lightweight static analysis tool that scans JavaScript files to help identify security vulnerabilities during the development process. It is built to be fast, easy to use, and ideal for developers looking to add a security layer to their codebase without complex configurations.

The tool scans your JavaScript files and provides feedback on potential vulnerabilities, allowing you to mitigate them before they reach production.

Features of sast-scan:

1. - Lightweight and Fast: No unnecessary complexity or overhead.
2. - Simple Integration: Add sast-scan to your projects with just a few commands.
3. - JavaScript Focused: Built with JavaScript security in mind.
4. - Open-Source: You can explore the code, contribute, or raise issues on GitHub.

How to Install and Use sast-scan:

1. Install the package:

To install sast-scan, use npm:

npm install sast-scan

1. Basic Usage: save file filename.js

import scanCode from 'sast-scan';
console.log(scanCode('const password = "12345";'));

Run file

node filename.js

Integrate the scanner into your project:

Here’s an example of how to integrate sast-scan into a React application:

import React, { useState } from 'react';
import scanCode from 'sast-scan'; // Import your npm package

const CodeScanner = () => {
    const [code, setCode] = useState('');
    const [results, setResults] = useState([]);

    const handleScan = () => {
        let vulnerabilities = [];
        try {
            vulnerabilities = scanCode(code); // Scan the code
        } catch (error) {
            console.error(`Error scanning code: ${error.message}`);
        }
        setResults(vulnerabilities);
    };

    return (
        <div>
            <h1 id="Code-Scanner">Code Scanner</h1>
            <textarea value="{code}" onchange="{(e)"> setCode(e.target.value)}
                placeholder="Enter code to scan"
            />
            <button onclick="{handleScan}">Scan Code</button>
            <div>
                {results.map((result, index) => (
                    <div key="{index}">
                        <p><strong>Vulnerability:</strong> {result.message}</p>
                        <p><strong>Fix:</strong> {result.fix}</p>
                        <p><strong>Line Number:</strong> {result.lineNumber}</p>
                    </div>
                ))}
            </div>
        </textarea>
</div>
    );
};

export default CodeScanner;

Output:

• Vulnerability: The vulnerability description
• Fix: Suggested fix
• Line Number: Line number of the issue
