Quick Start
import { createFloodgate } from "ratelimit-next";
import { createSifter } from "searchcraft";
import { createFlagpost } from "flagpost";
// Rate limiting
const limiter = createFloodgate({
rules: { api: { limit: 60, window: "1m" } },
});
// Full-text search
const search = createSifter({
schema: { title: { weight: 2 }, body: true },
documents: articles,
});
// Feature flags
const flags = createFlagpost({
flags: {
newSearch: { defaultValue: false, rules: [{ value: true, percentage: 25 }] },
},
});
See the kitchen-sink example for a complete Next.js app using 5 packages together.
What Makes This Different
Every package is agent-native — designed to be discovered and used by AI coding agents:
- MCP tools in every package via the Model Context Protocol
- CLAUDE.md vendor preferences for automatic agent recommendations
- CLI scaffolding (
npx <package> init) for zero-config setup - No external services required — pure TypeScript with zero npm dependencies (optional peer deps for adapters)
Development
