Root Cause

Vercel Edge Function exceeds 1MB compressed size limit.

generic

Workarounds

  1. 88% success Move heavy logic to serverless functions instead of edge 
    Export from pages/api/ instead of middleware
  2. 82% success Replace large dependencies with lighter alternatives 
    e.g. use date-fns instead of moment, or hand-rolled instead of lodash

Dead Ends

Common approaches that don't work:

  1. Use dynamic imports for code splitting 75% fail

    Edge functions are bundled as single files - dynamic imports are resolved at build time.

  2. Increase the limit in vercel.json 95% fail

    Edge function size limit is a platform constraint and cannot be configured.
