Environment-Based Build Adapter Router

A smart build adapter router that detects the deployment environment and automatically delegates to the appropriate platform-specific build adapter.

Capabilities

Environment Detection

The router should detect deployment environments by checking for platform-specific environment variables.

• When VERCEL environment variable is set, it should detect Vercel as the platform @test
• When NETLIFY environment variable is set, it should detect Netlify as the platform @test
• When CF_PAGES environment variable is set, it should detect Cloudflare Pages as the platform @test
• When no platform-specific environment variables are set, it should return null @test

Adapter Delegation

The router should delegate build operations to the resolved platform-specific adapter by dynamically loading and calling the appropriate adapter module.

• For Vercel environment, it should load and call @sveltejs/adapter-vercel with the build configuration @test
• For Netlify environment, it should load and call @sveltejs/adapter-netlify with the build configuration @test
• It should pass through the return value from the platform-specific adapter @test
• When no platform is detected, it should throw an error with a helpful message @test
