Microsoft has officially announced that the Azure SDK for JavaScript will stop supporting Node.js 20.x starting July 9, 2026. This decision follows the Node.js release lifecycle, as version 20.x is scheduled to reach its official End-of-Life (EOL) on April 30, 2026.

Why the Change?

Node.js follows a structured release schedule where even-numbered versions enter Long Term Support (LTS). Once a version reaches EOL, it no longer receives critical security updates or bug fixes. To maintain the security and performance of Azure services, the Azure SDK team routinely deprecates support for these outdated versions.

Key Deadlines and Impact

• April 30, 2026: Node.js 20.x reaches official End-of-Life.

• July 9, 2026: Azure SDK for JavaScript will set Node.js 22.x as the minimum supported version.

What happens if you stay on Node.js 20.x?

If you continue using Node.js 20.x after the July deadline:

1. Warnings: Installing newer versions of the Azure SDK will trigger engine deprecation warnings.

2. Errors: If your project configuration uses engine-strict=true, npm installations will fail entirely.

3. Security Risks: While older versions of the SDK may still function, they will not receive new features or security patches, potentially leaving your applications vulnerable.

Recommended Action for Developers

To ensure a smooth transition and continued support, developers are encouraged to upgrade their environments to the latest Active LTS version. Currently, Node.js 22.x is the recommended target for those moving away from 20.x.

Developers should review their dependency chains and CI/CD pipelines to ensure the Node.js runtime is updated before the July 2026 cutoff. For more details, you can refer to the official Azure SDK support policy.
