Welcome to HuanChain DevForum (forum.huanchain.online) — a full-featured developer community & technical publishing platform modeled after DEV.to (Forem), built on Next.js 15 App Router, Upstash Redis (L1/L2 Cache + Persistent Store), Cloudflare Edge Workers, and OpenAPI 3.0 / Swagger API.
Architecture Highlights
1. Dual-Engine Content Aggregation:
- Real-time synchronization with the global DEV.to / Forem REST API (Relevant, Latest, Top Week/Month/Year/Infinity, #tags, Podcasts, Videos, and nested discussion threads).
- Native HuanChain Community Persistence backed by Upstash Redis (huanchain:forum:articles:v1) so any article, reaction, or comment published here is immediately live across all edge nodes.
2. L1 Memory + L2 Redis Stale-While-Revalidate (SWR):
- Sub-5ms hot responses via in-memory L1 cache synchronized with Upstash Redis HTTP REST & ioredis TCP pipelines.
- Multi-emoji reactions (❤️ Heart, 🦄 Unicorn, 🤯 Exploding Head, 🙌 Raised Hands, 🔥 Fire) and 🔖 Reading List Bookmarks stored atomically in Redis hashes.
// Example: Atomic Reaction Increment via Upstash Redis
export async function reactToArticle(articleId: string, reaction: ReactionType) {
const field = ${articleId}:${reaction};
const updatedCount = await upstash.hincrby('huanchain:forum:reactions:v1', field, 1);
return updatedCount;
