Vercel Edge Runtime Support

Vercel Edge Runtime, built on Cloudflare Workers, offers a compelling solution for serverless computing by eliminating cold starts and reducing network latency, thanks to its global data center deployment and cost-effective infrastructure. However, its lack of Node.js compatibility can pose challenges, as developers may encounter unsupported API errors during deployment. Highlight supports the Edge Runtime by utilizing a customized version of the opentelemetry-sdk-workers package, addressing compatibility issues with Edge-incompatible API calls through strategic patching in the CI/CD pipeline. The Highlight team is exploring ways to simplify API endpoint wrapping in @highlight-run/next, considering both automated approaches using Rollup and static analysis, and a codemod for direct codebase edits, though these solutions require careful validation to ensure maturity and stability.
