Why

Shift-left security catches vulnerabilities early in the development lifecycle. Verizon DBIR 2024: 68% of breaches involve human error.

Snyk and Dependabot scan 500k+ npm packages for CVEs, and OWASP Top 10 hasn't changed much — injection and broken auth remain #1 and #2.

When

Use for production apps handling sensitive data. Avoid for internal-only prototypes.

How

1. Install Trivy 2. Configure scan rules/policies 3. Run scan in CI 4. Triage and fix findings 5. Add environment configuration — cp .env.example .env && edit values 6. Run tests — npm test or pnpm test to verify setup 7. Deploy — git push to trigger CI/CD or manual deploy

Example

# Trivy scan trivy_scan --target ./src # Review findings and fix // Trivy — usage example import { Trivy } from "sec-trivy"; const result = await trivy({ input: "data" }); console.log(result);

Common Problems

  • ⚠Trivy false positives noise — tune rules and suppress known-safe findings
  • ⚠Scan only in CI misses local issues — run {ne} in pre-commit hooks
  • ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

  • ✓Integrate Trivy into CI pipeline as a quality gate
  • ✓Keep {ne} rules updated to catch latest CVEs
  • ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is Trivy and what projects is it for?

Trivy — security tooling for vulnerability scanning, secrets, and policy. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.

How do I spin up a working demo with Trivy in 10 minutes?

Two steps: (1) Install Trivy; (2) Configure scan rules/policies. Get the local dev server running, then wire one real data source to verify the end-to-end loop.

What is the most common pitfall with Trivy and how do I avoid it?

The most common pitfall is: Trivy false positives noise — tune rules and suppress known-safe findings. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.

What are the best practices for Trivy?

Best practices for Trivy include: Integrate Trivy into CI pipeline as a quality gate; Keep {ne} rules updated to catch latest CVEs; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Integrate Trivy into CI pipeline as a quality gate" — should be set up at project init to avoid costly rework later.

When should I NOT choose Trivy?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Trivy shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
