ClickHouse Next.js

Build ClickHouse analytics into Next.js without duplicating query logic

Use hypequery to define a ClickHouse query once, run it inside App Router server components, and expose the same contract over HTTP for browser clients. This is the clean path for analytics-heavy Next.js apps.

Analytics logic drifts across routes and components

Teams often write one query in an API route, another in a server component, and a third in a cron job. The logic slowly diverges and debugging becomes guesswork.

Next.js developers need both server-side and browser access

Some analytics belong in server components or actions, while other screens need typed browser fetching. You need one definition that can serve both paths.

Raw ClickHouse clients leave too much wiring to the app team

You still need request validation, handler setup, and a reusable query layer that fits naturally into App Router instead of living as loose SQL strings.

Why this stack works

Use one typed query definition across the whole Next.js runtime

hypequery gives a Next.js team a stable analytics contract: typed ClickHouse queries, an App Router handler, and direct in-process execution when HTTP is unnecessary.

Generate schema types from your ClickHouse database
Define reusable analytics queries in TypeScript
Mount the same API under app/api/* with createFetchHandler
Run those queries directly in server components and actions
Add React hooks later without changing the server contract

App Router

Mount a typed analytics handler once

import { api } from '@/analytics/queries';
import { createFetchHandler } from '@hypequery/serve';

const handler = createFetchHandler(api.handler);

export const runtime = 'nodejs';
export const GET = handler;
export const POST = handler;
export const OPTIONS = handler;

This keeps your HTTP surface thin. The real analytics logic lives in shared query definitions, not inside the route file.

Server-first usage

Prefer local execution in server components, use HTTP for browser consumers

A strong Next.js setup does not force every analytics request through HTTP. Server code can call the query directly, while client-side charts can hit the same query through typed endpoints.

This split is especially useful for dashboards. Server components can render the initial state with low overhead, and interactive client components can progressively refetch via HTTP only where needed.

If React hooks are part of the plan, the dedicated ClickHouse React pillar and the React docs are the natural next step after this page.

Server component

Run the same query in-process

import { api } from '@/analytics/queries';

export default async function RevenuePage() {
  const revenue = await api.run('revenueByDay', {
    input: {
      startDate: '2026-01-01',
      endDate: '2026-01-31',
    },
  });

  return <pre>{JSON.stringify(revenue, null, 2)}</pre>;
}

You avoid network overhead inside the same app process while keeping the exact same validation and query definition.

Why teams search for this

Common implementation questions this page should solve

ClickHouse Next.js App Router setup

If you are searching for how to connect ClickHouse to App Router, the real answer is not just connection code. It is deciding which analytics stay local and which become reusable HTTP endpoints.

Next.js analytics dashboard architecture

Dashboards usually need SSR, client hydration, and typed re-fetching. A shared query layer stops those concerns from creating three versions of the same metric.

ClickHouse API routes in Next.js

You can expose typed analytics endpoints under `app/api/*` without hand-writing validation or response contracts for each route.

When to add React hooks

Use direct execution for server code first. Add hooks when browser-side interactivity needs cache-aware fetching and mutation ergonomics.
