How To Use Edge Functions With A CMS
AdvancedQuick Answer
TL;DR
Deploy lightweight serverless functions at CDN edge locations that fetch and transform CMS content at request time. Edge functions run in V8 isolates with sub-millisecond cold starts — far faster than traditional serverless functions. Use cases include personalization, A/B testing, geo-targeting, auth-gated content, and dynamic content assembly. The pattern: intercept the request at the edge, fetch from your CMS API, transform, return.
