Gen AI suggestions to solve the build error:

Based on the build output and error context, I'll analyze and provide specific fixes:

• Detected Error: Error during npm install/build step in ui/react-app directory
• Error Category: Build/Dependency
• Failure Point: cd ui/react-app && npm install && npm run build command
• Root Cause Analysis: The version of alertmanager (0.28.0) being built requires Node.js 23, but based on the changelog showing frontend updates and new UI features, there may be incompatibility with the Node.js version or missing build dependencies.

• Suggested Fix:

1. Update the environment section in the melange YAML to include yarn:

environment:
  contents:
    packages:
      - bash
      - build-base
      - busybox
      - ca-certificates-bundle
      - curl
      - go
      - nodejs
      - npm
      - yarn    # Add yarn package

2. Modify the build step to use yarn instead:

  - runs: |
      cd ui/react-app
      yarn install --network-timeout 100000
      yarn build
      cd ../..
      make build

• Explanation:

• Alertmanager's UI build system often works better with yarn
• The network timeout helps prevent connection issues during dependency installation
• Based on the changelog showing UI enhancements, using yarn provides more reliable dependency resolution
• Recent versions of Alertmanager prefer yarn for frontend builds

• Additional Notes:

• If the issue persists, you may need to add node-gyp to the environment packages
• Consider adding --frozen-lockfile to yarn install for reproducible builds
• The Node.js version (23) is recent enough for current Alertmanager UI requirements
