Summary

  • Add the public app.certified.feed.getReactionCounts query for batches of 1–100 subjects.
  • Return ordered, duplicate-preserving like/repost counts using distinct publisher DIDs and URI-only matching.
  • Register the handler, tests, API docs, explorer snapshots, consumer skill contract, and a minor Changeset.

Validation

  • node --test api/tests/unit/tooling/feed-reactions.test.js — 11/11 passed.
  • pnpm check — passed (351 unit tests, 17 docs tests; generated bundle current).
  • pnpm build — passed.
  • pnpm changeset status — minor bump for @hypercerts-org/hypercerts-api.
  • git diff --check — passed.

Runtime test limitation

PSQL_PATH="$(command -v psql)" pnpm test:http stopped at the cached-image preflight because the pinned PostgreSQL image is unavailable locally. No image pull or Compose startup occurred; installed HTTP/SQL behavior remains unverified.

Summary by CodeRabbit

  • New Features
    • Added a public query for retrieving like and repost counts for 1–100 subject records in a single request. Results preserve the order of requested subjects, including duplicates, and count distinct publishers by subject URI.
  • Documentation
    • Documented the query’s request format, response, and behavior.

📝 Walkthrough

Adds app.certified.feed.getReactionCounts, which accepts 1–100 subject AT-URIs and returns like and repost counts in input order, including duplicate subjects. The query validates subjects, reads indexed reactions from PostgreSQL, and is registered with its lexicon, API references, and tests.

Changes: Feed reaction counts

Layer / File(s) Summary
Query contract and subject validation
api/lexicons/app.certified.feed.getReactionCounts.json, docs/sources/lexicons/app.certified.feed.getReactionCounts.json, api/lua/endpoints/getReactionCounts.lua, api/lua/src/getReactionCounts.lua, .agents/skills/hypercerts-api/references/*, api/README.md
Defines the query parameters, response shape, and errors. The Lua implementations validate subject AT-URIs and accept 1–100 subjects. The API references document repeated parameters, ordered results, and count semantics.
Indexed counts and ordered response
api/lua/endpoints/getReactionCounts.lua, api/lua/src/getReactionCounts.lua, api/tests/http/feed-reactions.http.test.js, api/tests/unit/tooling/feed-reactions.test.js
Queries distinct like and repost publishers from PostgreSQL. The response preserves input order and duplicates, and uses zero counts when no indexed reactions match. Tests cover results, invalid requests, backend restrictions, and query failures.
Registration and endpoint references
api/manifest.json, api/modules/feed-reactions/manifest.json, docs/coverage.json, docs/openapi.json, docs/sources/index.json, .changeset/batch-reaction-counts.md
Registers the query and lexicon, updates endpoint and OpenAPI indexes, and adds a minor package changeset.

🟡 Minor · Update the endpoint-map totals. · endpoint-map.md:3

.agents/skills/hypercerts-api/references/endpoint-map.md:3
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Update the endpoint-map totals.

The new getReactionCounts entry makes the Line 3 total 63, not 62. It also makes the Line 88 feed-reactions total 6, not 5. Update both totals so consumers can rely on this self-contained map. As per coding guidelines, “keep its bundled OpenAPI snapshot, endpoint map, and relevant consumer guidance aligned too.”

Also applies to: 88-88
