ReleaseRun Badges for Node.js

Why Use Node.js Health Badges?

Node.js has one of the most confusing release schedules in the ecosystem. Even-numbered releases get LTS. Odd numbers don not. Support windows overlap. Security patches land on multiple branches simultaneously. A health badge cuts through the noise.

Our badges show three things Shields.io cannot: CVE counts per version, EOL countdowns, and a composite health grade that tells you whether a specific Node.js version is safe to run in production right now.

Node.js Release History & EOL Timeline

Node.js releases a new major version every six months (April and October). Even-numbered versions enter Long-Term Support (LTS) 6 months after initial release, then receive 30 months of total support — 18 months of active LTS followed by 12 months of maintenance. Odd-numbered versions get only 6 months of current support and never enter LTS.

• Node.js 23 — released October 2024. Current (non-LTS). Support ends April 2025. Not recommended for production.
• Node.js 22 — released April 2024, entered LTS October 2024 (codenamed “Jod”). Active LTS until October 2025, maintenance until April 2027.
• Node.js 20 — released April 2023, LTS since October 2023 (codenamed “Iron”). Active LTS until October 2024, maintenance until April 2026.
• Node.js 18 — released April 2022, LTS since October 2022 (codenamed “Hydrogen”). Entered end-of-life April 2025. If you are still running Node 18, the EOL badge will flag it immediately.
• Node.js 16 and earlier — already end-of-life. No security patches. The ReleaseRun health badge drops to an F grade.

The LTS vs Current distinction trips up many teams. Health badges make the distinction visual — LTS versions in active support show green; non-LTS or maintenance versions show amber; EOL versions show red.

Badge Customization Examples

Four badge types are available for Node.js, each serving a different monitoring purpose:

• Health badge — composite A–F grade. Embed: ![Node.js Health](https://img.releaserun.com/badge/health/nodejs.svg)
• Freshness badge — how current your version is. Embed: ![Node 22](https://img.releaserun.com/badge/v/nodejs/22.13.1.svg)
• EOL badge — end-of-life status. Embed: ![Node 20 EOL](https://img.releaserun.com/badge/eol/nodejs/20.svg)
• CVE badge — vulnerability count. Embed: ![Node 22 CVEs](https://img.releaserun.com/badge/cve/nodejs/22.13.1.svg)

Customise with ?style=flat-square or ?style=for-the-badge. The embed builder above generates ready-to-copy snippets in Markdown, HTML, and reStructuredText.

Who Should Use These

• npm package maintainers: Show which Node.js versions your package supports and their health status. Your users running Node 18 will see the LTS timeline reflected in the badge.
• Framework authors: Pin minimum supported versions with visual proof. When Node 18 hits EOL, the badge automatically signals it.
• Platform teams: Track Node.js versions across microservices. Health badges in your service catalog make version debt visible.
