EdgeOne Pages Development Guide

Develop full-stack applications on EdgeOne Pages — Edge Functions, Cloud Functions (Node.js / Go / Python), and Middleware.

When to use this skill

• Creating APIs, serverless functions, or backend logic on EdgeOne Pages
• Adding middleware for request interception, redirects, auth guards, or A/B testing
• Building full-stack apps with static frontend + server-side functions
• Using KV Storage for edge-side persistent data
• Setting up WebSocket endpoints (Node.js runtime)
• Integrating Express, Koa, Gin, Echo, Flask, FastAPI, or Django on EdgeOne Pages
• Debugging EdgeOne Pages runtime errors (function failures, middleware issues, KV problems)

Do NOT use for:

• Deployment → use edgeone-pages-deploy skill
• Next.js / Nuxt middleware or API routes → use the framework's own API, NOT the platform middleware.js
• Generic Express/Koa/Gin/Flask development outside an EdgeOne Pages project
• Cloudflare Workers, Vercel Functions, or other platforms
