Dashboard Builder

Build professional data visualization dashboards with modern UI, rich visualizations, and dynamic effects.

Tech Stack

• Frontend: Next.js 14+ (App Router) + React 18+
• UI Components: shadcn/ui + Tailwind CSS
• Charts: Recharts
• Animations: Framer Motion
• Backend: Express.js
• Data Sources: Configurable APIs, databases, or static data

Design Requirements

Visual Style (Professional PC Dashboard)

• Dark theme with subtle gradients (not flashy)
• Clean card design with soft shadows and borders
• Professional color palette:
  • Background: slate-900 (#0f172a) to slate-950 (#020617)
  • Cards: slate-800/50 with subtle border
  • Success: emerald-500 (#10b981)
  • Danger: rose-500 (#f43f5e)
  • Accent: blue-500 (#3b82f6)
• Large typography optimized for big screens (4K, ultra-wide)
• Grid-based layout with clear visual hierarchy

Animation Requirements

• Entrance animations: Subtle fade in + slide up on page load
• Scroll-triggered animations: Cards animate when scrolling into view
• Number counting animation: Values animate smoothly
• Progress bar animation: Bars fill with easing
• Hover effects: Cards lift slightly with shadow
• Live data pulse: Subtle indicator when data updates

Animated Number

'use client'
import { useEffect, useState } from 'react'
import { animate } from 'framer-motion'

interface AnimatedNumberProps {
  value: number
  decimals?: number
  duration?: number
}

export function AnimatedNumber({ value, decimals = 2, duration = 1 }: AnimatedNumberProps) {
  const [display, setDisplay] = useState(0)

  useEffect(() => {
    const controls = animate(display, value, {
      duration,
      ease: "easeOut",
      onUpdate: (v) => setDisplay(v)
    })
    return () => controls.stop()
  }, [value, duration])

  return <>{display.toFixed(decimals)}</>
}

Live Indicator

export function LiveIndicator() {
  return (
    <div className="flex items-center gap-2">
      <span className="relative flex h-3 w-3">
        <span className="animate-ping absolute inline-flex h-full w-full rounded-full bg-emerald-400 opacity-75" />
        <span className="relative inline-flex rounded-full h-3 w-3 bg-emerald-500" />
      </span>
      <span className="text-emerald-500 text-sm font-medium">LIVE</span>
    </div>
  )
}

Automation Scripts

Automatic Setup and Run

To simplify the development setup process, we provide an automated script that will:

1. Create a new Next.js project with all required dependencies
2. Install shadcn/ui components
3. Set up sample dashboard components
4. Start the development server

Run the setup script with:

./setup-and-run.sh

The script will prompt you for a project name and automatically handle all setup steps, then start the development server at http://localhost:3000.

Manual Setup

If you prefer manual setup, follow these steps:

1. Create a new Next.js app:

   npx create-next-app@latest my-dashboard --typescript --tailwind --eslint
   

2. Install required dependencies:

   cd my-dashboard
   npm install shadcn-ui recharts framer-motion lucide-react
   

3. Initialize and add shadcn/ui components:

   npx shadcn-ui@latest init
   npx shadcn-ui@latest add card button badge table scroll-area alert
   

4. Start the development server:

   npm run dev

Auto-Refresh Hook

'use client'
import { useEffect, useState, useCallback } from 'react'

export function useLiveData<T>(
  fetcher: () => Promise<T>,
  interval = 60000
) {
  const [data, setData] = useState<T | null>(null)
  const [loading, setLoading] = useState(true)
  const [isRefreshing, setIsRefreshing] = useState(false)
  const [lastUpdated, setLastUpdated] = useState<Date | null>(null)

  const refresh = useCallback(async () => {
    setIsRefreshing(true)
    try {
      const result = await fetcher()
      setData(result)
      setLastUpdated(new Date())
    } finally {
      setLoading(false)
      setTimeout(() => setIsRefreshing(false), 300)
    }
  }, [fetcher])

  useEffect(() => {
    refresh()
    const timer = setInterval(refresh, interval)
    return () => clearInterval(timer)
  }, [refresh, interval])

  return { data, loading, isRefreshing, lastUpdated, refresh }
}
