az webapp create,  az webapp list-runtimes

Description

Use  NODE|26 as the standard Node.js 26 runtime identifier for both Windows and Linux App Service plans by dropping LTS / -lts from the identifier. LTS is lifecycle metadata, not part of the Node version itself. Existing identifiers for Node.js 24 and earlier remain unchanged and supported.

Testing Guide

azdev test TestStackRuntimeNodeStandardization
azdev style appservic

The added tests verify:

• Node 26 displays as  NODE|26  on both platforms.
• Linux configuration is exactly  NODE|26 .
• Windows configuration remains  ~26 .
•  NODE|26-lts  and  NODE|26LTS  resolve successfully.
• Node 24 identifiers remain unchanged.
• Current and LTS API entries are deduplicated.
• GitHub Actions returns  NODE|26  and version  26.x .
