Question 1

How do I handle false positives in eslint-plugin-security?

Accepted Answer

You can configure individual rules to be disabled or adjusted in your ESLint config. For example, use rule overrides in your eslint.config.js to set specific patterns to 'off' or reduce severity, as the plugin allows granular control despite the high false positive rate mentioned in the README.

Question 2

eslint-plugin-security vs Snyk: which is better for Node.js security?

Accepted Answer

eslint-plugin-security is a lightweight, ESLint-integrated tool for catching code patterns during development, while Snyk offers broader vulnerability scanning including dependencies and runtime analysis. For deep security audits, Snyk is more comprehensive, but for quick, integrated linting, eslint-plugin-security is efficient and cost-effective.

Question 3

Does eslint-plugin-security work with frontend frameworks like React or Vue?

Accepted Answer

Primarily designed for Node.js, it focuses on server-side vulnerabilities such as child process or filesystem issues. While some rules might apply to JavaScript in general, it's not optimized for frontend-specific security concerns, so it's best used in Node.js backend environments.

Question 4

How to configure eslint-plugin-security with TypeScript in a new project?

Accepted Answer

Install the plugin and the @types/eslint-plugin-security package via npm, then add it to your ESLint config. For flat config (ESLint >=8.23.0), import pluginSecurity and use the recommended setup as shown in the README, ensuring compatibility with your TypeScript ESLint parser.

Question 5

What are the most critical rules to enable in eslint-plugin-security?

Accepted Answer

Rules like detect-bidi-characters for trojan source attacks and detect-eval-with-expression for arbitrary code execution are highly critical. The recommended configuration includes all rules set to warn, but you can prioritize those based on your project's risk profile and the README's descriptions.

Question 6

Can I use eslint-plugin-security in CI/CD pipelines without slowing down builds?

Accepted Answer

Yes, it integrates easily by running ESLint with the plugin in your pipeline. However, due to false positives, you might need to tune rules to avoid excessive warnings or use it as a non-blocking check, balancing security with build performance.
