redblue-cli

library0.2.33jsnpmunverified

redblue is a security CLI tool written in Rust, providing 90+ commands for network scanning, DNS, recon, web fuzzing, TLS, authentication testing, exploit, binary analysis, password cracking, evasion, secrets detection, vulnerability intelligence, and proxy/C2 capabilities. The npm package redblue-cli v0.2.33 wraps the rb binary for JavaScript/TypeScript ecosystems, supporting npx and npm exec. Requires Node.js >=20. It is actively maintained with frequent releases. Key differentiator: zero-dependency binary with 40+ protocols implemented from scratch.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import redblue from 'redblue-cli'

✗ const redblue = require('redblue-cli')

ESM-only since v0.2.0; CommonJS require is not supported.

✓ import { rb } from 'redblue-cli'

✗ const rb = require('redblue-cli').rb

Use named import for the rb function which executes the CLI.

RedblueConfig

✓ import type { RedblueConfig } from 'redblue-cli'

TypeScript type available for configuration object.

Shows how to use the redblue-cli SDK to run various security commands: DNS lookup, TLS cipher scan, and subdomain bruteforce.

import { rb } from 'redblue-cli'; async function main() { // Run a DNS lookup with custom options const result = await rb('dns', 'record', 'lookup', 'example.com', '--type', 'MX'); console.log('DNS records:', result); // Run a TLS cipher enumeration const tlsResult = await rb('tls', 'cipher', 'scan', 'example.com', '--port', '443'); console.log('TLS ciphers:', tlsResult); // Run a subdomain discovery const subdomains = await rb('recon', 'subdomain', 'bruteforce', 'example.com', '--wordlist', '/path/to/wordlist.txt'); console.log('Subdomains found:', subdomains); } main().catch(console.error);

Debug

Known issues

gotchaThe rb binary requires libc as a runtime dependency; ensure it's available on your system.

fix

Install libc (e.g., glibc on Linux) or use a static build if available.

affects: all

breakingVersion 0.2.0 changed from CJS to ESM; require() no longer works.

fix

Use dynamic import() or switch to ESM (type: module in package.json).

affects: >=0.2.0

deprecatedThe '--format' flag for output was replaced with '--output' in newer releases.

fix

Use '--output' instead of '--format'.

affects: <0.2.20

gotchaSome commands may require root privileges for raw sockets; they will fail silently if not permitted.

fix

Run the binary with sudo or appropriate capabilities (CAP_NET_RAW).

affects: all

gotchaThe npm package does not include the binary for all platforms; only linux-x86_64 is bundled. Other platforms must use the separate binary download.

fix

Install the binary manually for non-Linux systems or use a CI matrix.

affects: all

Errors

Common errors & fixes

Cannot find module 'redblue-cli'

The package is not installed or is missing from package.json.

fix

Run 'npm install redblue-cli' to install the npm package.

Error: spawn rb ENOENT

The rb binary is not found in PATH or not bundled with the npm package.

fix

Ensure the binary is installed via curl or download, and add it to PATH.

TypeError: rb is not a function

Using require() with ESM-only package version >=0.2.0.

fix

Use import { rb } from 'redblue-cli' or dynamic import.

Error: Command failed with exit code 1: rb dns record lookup example.com --type MX

The DNS lookup failed, possibly due to network issues or invalid domain.

fix

Check network connectivity and domain name; use --verbose for more details.
