eslint-plugin-node-security

Security-focused ESLint plugin for Node.js built-in modules (fs, child_process, vm, crypto, Buffer).

Description

This plugin provides Security rules for Node.js core modules (fs, child_process, crypto, etc).
By using this plugin, you can proactively identify and mitigate security risks across your entire codebase.

Philosophy

Interlace fosters strength through integration. Instead of stacking isolated rules, we interlace security directly into your workflow to create a resilient fabric of code. We believe tools should guide rather than gatekeep, providing educational feedback that strengthens the developer with every interaction.
