Summary
Closes #504 — adds caching and pagination for the high-volume marketplace, served from the event indexer's Prompt collection (roadmap item: external indexer for search/pagination at scale).
The previous
GET /api/promptsreturned every published prompt with no pagination, search, or sort — untenable at scale. It now reads from the indexed collection through a cached, paginated, searchable read model.Changes
models/Prompt.js: added a full-text search index (title/content/category/tags) and compound sort indexes (createdAt, price, salesCount, rating, each paired with_id) so search/pagination avoid full collection scans.services/marketplaceIndexService.ts(new): the indexer-backed read model.searchMarketplace()supports:search,category,tags,minPrice/maxPrice,similarityFlag,walletAddressprompts:list:*— automatically invalidated byinvalidatePromptMetadataon every indexed contract eventcontrollers/controllers.ts:GetPromptsdelegates tosearchMarketplace, returning a paginated envelope (items/total/page/limit/totalPages/nextCursor/hasNext/cached) instead of a bare array. AddedGetMarketplaceIndexStatus.routes/promptRoutes.ts: newGET /api/prompts/index/statusfor indexer visibility (registered before/:id).marketplaceIndexService.test.ts+getPrompts.test.ts— 10/10 passing.Test plan
cd server && npx jest src/tests/marketplaceIndexService.test.ts src/tests/getPrompts.test.ts
Usage
GET /api/prompts?search=...&category=Programming&tags=ai,seo&minPrice=1&maxPrice=50&sort=price_desc&limit=24&cursor=
Notes
server/package-lock.jsonchange from localnpm installwas intentionally excluded from the commit.tscreports pre-existing type errors across many controllers (theasyncRoute/AsyncHandlermismatch from@types/express@5); none are introduced by this change, and the new code is type-clean.
