initdev-nmap

A robust, chainable Nmap wrapper for Node.js using the Builder pattern and Fluent Interface.

Installation

npm install initdev-nmap

Prerequisites:

• Nmap must be installed and available in your system PATH.

Usage

import { scan } from "initdev-nmap";

// Simple scan
const result = await scan("192.168.1.1").run();
console.log(result);

// Advanced chainable scan
const advancedResult = await scan("192.168.1.0/24")
    .scanType("syn")
    .os()
    .serviceInfo()
    .ports([22, 80, 443])
    .timing(4)
    .script("vuln")
    .verbose()
    .run();

console.log(advancedResult);

API

scan(target)

Initializes a new scan builder for the specified target.

Chainable Methods

All methods return the builder instance for chaining, except run().

• target(value): Sets the target IP or hostname.
• ports(ports): Sets ports to scan. Accepts string ("80"), array ([22, 80]), or range ("1-100").
• scanType(type): Sets the scan type. Supported: syn, udp, connect, ack, window, maimon.
• os(): Enables OS detection (-O).
• serviceInfo() / version(): Enables service version detection (-sV).
• aggressive(): Enables aggressive scan options (-A).
• timing(level): Sets timing template (0-5).
• script(name): Runs a script or script category.
• scriptArgs(obj): Sets script arguments from an object (--script-args key=value).
• topPorts(n): Scans the top n ports.
• exclude(hosts): Excludes hosts from the scan.
• maxRetries(n): Sets the maximum number of port scan probe retransmissions.
• maxRate(n): Sets the maximum packet send rate.
• minRate(n): Sets the minimum packet send rate.
• dnsServers(list): Sets custom DNS servers.
• ipv6(): Enables IPv6 scanning (-6).
• disablePing(): Disables host discovery (-Pn).
• verbose(level): Sets verbosity level (default 1).
• quiet(): Suppresses verbose output.
• output(type): Sets output format. Supported: xml (default), normal, grepable.
• option(opt): Adds a custom raw Nmap option.
• sudo(): Runs the Nmap command with sudo.

run()

Executes the Nmap command. Returns a Promise that resolves to:

• A JSON object (parsed from XML) if output is xml (default).
• A string if output is normal or grepable.
