    }"
  />
</template>

<script setup lang="ts">
import { GradFlow } from "gradflow-vue";
</script>

Using Hex Colors

<template>
  <GradFlow
    :config="{
      color1: '#e2624b',
      color2: '#ffffff',
      color3: '#1e229f',
    }"
  />
</template>

<script setup lang="ts">
import { GradFlow } from "gradflow-vue";
</script>

Using Presets

<template>
  <GradFlow :config="PRESETS.cosmic" />
</template>

import { GradFlow, PRESETS } from "gradflow";
</script>

Available presets: cosmic, matrix, electric, inferno, mystic, cyber, neon, plasma

Reactive Configuration

<template>
  <GradFlow :config="gradientConfig" />
  <button @click="randomizeColors">Randomize</button>
</template>

<script setup lang="ts">
import { ref } from "vue";
import { GradFlow, generateRandomColors, PRESETS } from "gradflow";

const gradientConfig = ref(PRESETS.cosmic);

const randomizeColors = () => {
  gradientConfig.value = generateRandomColors();
};
</script>

Full Screen Background

<template>
  <div class="relative h-screen w-full">
    <GradFlow :config="PRESETS.cosmic" class="absolute inset-0" />
    <div class="relative z-10">
      <!-- Your content here -->
    </div>
  </div>
</template>

<script setup lang="ts">
import { GradFlow, PRESETS } from "gradflow";
</script>

API Reference

GradFlow Component

| Prop | Type | Default | Description | | ----------- | --------------------- | ---------------- | ----------------------------- | | config | GradientConfigInput | DEFAULT_CONFIG | Gradient configuration object | | className | string | '' | Additional CSS classes |

GradientConfigInput

All properties are optional. You can use either hex strings or RGB objects for colors.

type GradientConfigInput = {
  color1?: string | RGB; // First gradient color
  color2?: string | RGB; // Second gradient color
  color3?: string | RGB; // Third gradient color
  speed?: number; // Animation speed (0.1-3.0)
  scale?: number; // Pattern scale (0.5-3.0)
  type?: GradientType; // Gradient pattern type
  noise?: number; // Noise intensity (0-0.5)
};

type RGB = {
  r: number; // 0-255
  g: number; // 0-255
  b: number; // 0-255
};

Gradient Types

• linear - Classic linear gradient with wave distortion
• animated - Dynamic flowing patterns with rotation
• conic - Circular/radial gradient patterns
• wave - Wave-based undulating patterns
• silk - Smooth silk-like flowing textures
• smoke - Organic smoke-like patterns
• stripe - Warped stripe patterns (default)

Utility Functions

Color Conversion

import { hexToRgb, rgbToHex, normalizeColor } from "gradflow-vue";

// Convert hex to RGB
const rgb = hexToRgb("#ff0000"); // { r: 255, g: 0, b: 0 }

// Convert RGB to hex
const hex = rgbToHex({ r: 255, g: 0, b: 0 }); // '#ff0000'

// Normalize color (accepts both string and RGB)
const normalized = normalizeColor("#ff0000"); // { r: 255, g: 0, b: 0 }

Random Colors

import { randomRGB, generateRandomColors } from "gradflow-vue";

// Generate single random RGB color
const color = randomRGB();

// Generate random gradient colors
const colors = generateRandomColors();
// Returns: { color1: RGB, color2: RGB, color3: RGB }

Nuxt 3 Integration

Auto-import (Recommended)

Nuxt 3 will automatically import components. Just use GradFlow in your templates:

<template>
  <GradFlow :config="PRESETS.cosmic" />
</template>

Manual Import

If auto-import is disabled, import explicitly:

<template>
  <GradFlow :config="gradientConfig" />
</template>

<script setup lang="ts">
import { GradFlow, PRESETS } from "gradflow";

const gradientConfig = PRESETS.cosmic;
</script>

Nuxt Plugin (Optional)

Create a plugin to make GradFlow available globally:

// plugins/gradflow.client.ts
import { defineNuxtPlugin } from "#app";

export default defineNuxtPlugin(() => {
  // GradFlow is available globally via auto-import
});

Performance Tips

• Use scale values between 0.5-2.0 for optimal performance
• Lower noise values (< 0.2) perform better
• The component automatically limits device pixel ratio to 2 for performance
• Canvas automatically resizes on window resize events

Requirements

• Vue >= 3.5.0
• Nuxt >= 3.13.0 (if using Nuxt)
• Modern browser with WebGL support

Browser Support

GradFlow works in all modern browsers that support WebGL:

• Chrome 56+
• Firefox 51+
• Safari 15+
• Edge 79+

TypeScript

GradFlow is written in TypeScript and provides full type definitions:

import type {
  GradFlowProps,
  GradientConfig,
  GradientConfigInput,
  RGB,
  GradientType,
} from "gradflow-vue";

Note: This component requires WebGL support. It gracefully handles unsupported environments but won't render gradients in very old browsers.
