The type-safe analytics backend for ClickHouse

Build ClickHouse queries once, run them inline, over HTTP, in React, or from agents.

Docs • Roadmap • Examples

Why hypequery

• Build on top of your real ClickHouse schema instead of hand-maintained query types
• Reuse the same query definition across scripts, APIs, React apps, and agents
• Start local with the query builder, then add HTTP routes only when you need them
• Keep inputs, outputs, and SQL behavior explicit enough to test and reason about

Packages

• @hypequery/clickhouse: typed ClickHouse query builder
• @hypequery/serve: code-first runtime for query contracts, HTTP routes, docs, and adapters
• @hypequery/react: thin TanStack Query hooks for hypequery APIs
• @hypequery/cli: scaffolding, schema generation, and local dev tooling

Quick Start

npm install -D @hypequery/cli
npx hypequery init

That gives you the main path:

1. Generate schema types from ClickHouse
2. Write typed queries locally
3. Expose the queries over HTTP when you need a shared contract

Query Builder

import { createQueryBuilder } from '@hypequery/clickhouse';
import type { IntrospectedSchema } from './analytics/schema.js';

const db = createQueryBuilder<IntrospectedSchema>({
  url: process.env.CLICKHOUSE_URL!,
  username: process.env.CLICKHOUSE_USERNAME!,
  password: process.env.CLICKHOUSE_PASSWORD ?? '',
  database: process.env.CLICKHOUSE_DATABASE!,
});

const revenueByRegion = await db
  .table('orders')
  .select(['region'])
  .where('created_at', 'gte', '2026-01-01')
  .sum('total', 'revenue')
  .groupBy('region')
  .orderBy('revenue', 'DESC')
  .execute();

Add Contracts And HTTP When Needed

import { initServe } from '@hypequery/serve';
import { z } from 'zod';
import { db } from './analytics/client.js';

const { query, serve } = initServe({
  context: () => ({ db }),
  basePath: '/api/analytics',
});

const activeUsers = query({
  description: 'List active users by region',
  input: z.object({ region: z.string() }),
  query: ({ ctx, input }) =>
    ctx.db
      .table('users')
      .where('status', 'eq', 'active')
      .where('region', 'eq', input.region)
      .execute(),
});

export const api = serve({
  queries: { activeUsers },
});

api.route('/activeUsers', api.queries.activeUsers);

The same query can then be:

• executed directly with api.execute(...)
• exposed as an HTTP route
• consumed from React with @hypequery/react
• described for tools and agents

CLI

# Scaffold analytics files and env vars
npx hypequery init

# Run the local dev server with docs
npx hypequery dev

# Regenerate schema types
npx hypequery generate
