v1.4.0

What's New

MongoDB Store

Atomic $inc + $setOnInsert upserts with TTL indexes for auto-cleanup. Works on both Node.js and Bun.

import { mongoStore } from '@joint-ops/hitlimit/stores/mongodb'
app.use(hitlimit({ store: mongoStore({ db }) }))

MySQL Store

Atomic INSERT ON DUPLICATE KEY UPDATE with scheduled cleanup. Works on both Node.js and Bun.

import { mysqlStore } from '@joint-ops/hitlimit/stores/mysql'
app.use(hitlimit({ store: mysqlStore({ pool }) }))

Benchmark Infrastructure

• New interactive benchmark CLI replacing legacy shell scripts
• Centralized benchmarks.json as single source of truth for all 50+ doc pages
• 34 benchmark result files for v1.4.0 across all frameworks and stores
• CI/CD workflows with MongoDB and MySQL service containers

Performance

• Bun SQLite: Added PRAGMA journal_mode = WAL for parity with Node.js
• MongoDB optimization: Replaced aggregation pipeline with direct upserts (~2x throughput)

Documentation

• All doc pages now consume live benchmark data — no more hardcoded numbers
• Overhauled READMEs with collapsible store sections and ASCII deployment diagrams
• New store pages: /docs/stores/mongodb and /docs/stores/mysql
• Benchmark page rewrite with runtime-tabbed UI
