Root Cause

Vercel Edge Functions have a 1MB compressed size limit.

generic

Workarounds

  1. 90% success Move heavy dependencies to serverless functions and call from edge 
    Edge function handles routing; calls serverless for heavy work

    Sources: https://vercel.com/docs/functions/edge-functions/limitations

  2. 82% success Use dynamic imports and code splitting 
    const heavy = await import('./heavy.js')

Dead Ends

Common approaches that don't work:

  1. Tree-shake imports to reduce bundle size 60% fail

    Some libraries are not tree-shakeable

  2. Minify the code more aggressively 55% fail

    Minification has diminishing returns; large dependencies are the problem
