Component Organization

When creating React components for a feature page, never put multiple component functions in a single page.tsx file.

Pattern

Instead of this (BAD):

features/analytics/
  page.tsx  <- Contains Page + SummaryCard + DailyActivityChart + etc.

Do this (GOOD):

features/analytics/
  page.tsx           <- Only imports and composes components
  components/
    summary-card.tsx
    daily-activity-chart.tsx
    hourly-activity-chart.tsx
    tokens-chart.tsx
    model-usage-card.tsx

Implementation

1. •

   page.tsx should only contain:

   • •Imports from ./components/
   • •The main Page function that composes the imported components
   • •Data fetching/loader logic if needed
2. •

   components/ folder should contain:

   • •One component per file
   • •File names in kebab-case matching the component name
   • •Each file exports a single named component

Example

page.tsx:

import { SummaryCard } from './components/summary-card'
import { DailyActivityChart } from './components/daily-activity-chart'

export function Page() {
  return (
    <div>
      <SummaryCard />
      <DailyActivityChart />
    </div>
  )
}

components/summary-card.tsx:

export function SummaryCard({ title, value, icon }: SummaryCardProps) {
  return (...)
}

When to Apply

• •Creating a new feature page with 2+ custom components
• •Refactoring an existing page with inline components
• •The page.tsx file exceeds ~100 lines
