nimate

nimate

nimate is a simple, flexible animation library designed to work across all JavaScript environments. With nimate, you can create smooth animations and sequence them with ease, utilizing easing functions from the ts-easing package.

✨ Features

• Supports animations of numbers, objects, and arrays.
• streamich/ts-easing for easing.
• Configurable sequences that can run in parallel or series.
• Works in browsers, Node.js, and other JavaScript environments.
• Emits events for start, update, complete, and stop for animations and sequences.

📦 Installation

Install the library using npm:

npm install nimate

💻 Usage

Basic Animation

import { Animate, Easing } from 'nimate';

// Create an animation
const animate = new Animate({
  from: { x: 0, y: 0 },
  to: { x: 100, y: 50 },
  duration: 1000,
  easing: Easing.easeInOutQuad,
});

animate
  .on('start', () => console.log('Animation Start'))
  .on('update', value => console.log('Animation Update:', value))
  .on('complete', () => console.log('Animation Complete'))
  .on('stop', () => console.log('Animation Stop'))
  .start();

Sequence of Animations

import { Animate, Sequence, Easing } from 'nimate';

// Create individual animations
const animate1 = new Animate({
  from: { x: 0, y: 0, nested: { z: 0 } },
  to: { x: 100, y: 50, nested: { z: 100 } },
  duration: 1000,
  easing: Easing.easeInOutQuad,
});

const animate2 = new Animate({
  from: [0, 0, { a: 0 }],
  to: [100, 50, { a: 100 }],
  duration: 1000,
  easing: Easing.easeInOutQuad,
});

// Create a sequence with the animations
const sequence = new Sequence({ items: [animate1, animate2] });

// Attach event listeners
sequence
  .on('start', () => console.log('Sequence Start'))
  .on('update', value => console.log('Sequence Update:', value))
  .on('complete', () => console.log('Sequence Complete'))
  .on('stop', () => console.log('Sequence Stop'))
  .start();

Parallel Sequences

import { Animate, Sequence, Easing } from 'nimate';

// Create individual animations
const animate1 = new Animate({
  from: { x: 0, y: 0, nested: { z: 0 } },
  to: { x: 100, y: 50, nested: { z: 100 } },
  duration: 1000,
  easing: Easing.easeInOutQuad,
});

const animate2 = new Animate({
  from: [0, 0, { a: 0 }],
  to: [100, 50, { a: 100 }],
  duration: 1000,
  easing: Easing.easeInOutQuad,
});

const animate3 = new Animate({
  from: { x: 50, y: 50 },
  to: { x: 150, y: 100 },
  duration: 1000,
  easing: Easing.easeInOutQuad,
});

// Create a sequence with the animations
const sequence1 = new Sequence({ items: [animate1, animate2] });

// Create a parallel sequence
const parallelSequence = new Sequence({ items: [sequence1, animate3], parallel: true });

// Attach event listeners
parallelSequence
  .on('start', () => console.log('Parallel Sequence Start'))
  .on('update', value => console.log('Parallel Sequence Update:', value))
  .on('complete', () => console.log('Parallel Sequence Complete'))
  .on('stop', () => console.log('Parallel Sequence Stop'));

// Start the sequence
parallelSequence.start();

📚 API

Animate

Creates an animation instance.

Options

• from (AnimatableValue): The initial value.
• to (AnimatableValue): The target value.
• duration (number): The duration of the animation in milliseconds.
• easing (EasingFunction, optional): The easing function to use. Default is Easing.linear.
• delay (number, optional): The delay before the animation starts in milliseconds. Default is 0.
• direction ('normal' | 'reverse' | 'alternate', optional): The direction of the animation. Default is 'normal'.
• loop (number, optional): The number of times the animation should loop. Default is 1.

Methods

• start(): Starts the animation.
• stop(): Stops the animation.

Events

• start: Emitted when the animation starts.
• update: Emitted on each update with the current value.
• complete: Emitted when the animation completes.
• stop: Emitted when the animation is stopped.

Sequence

Creates a sequence of animations.

Options

• items (SequenceItem[]): The animations or sequences to include in the sequence.
• parallel (boolean, optional): Whether the items should run in parallel. Default is false.

Methods

• start(): Starts the sequence.
• stop(): Stops the sequence.

Events

• start: Emitted when the sequence starts.
• update: Emitted on each update with the current value.
• complete: Emitted when the sequence completes.
• stop: Emitted when the sequence is stopped.
