# :wavy_dash: Spring
[:books: **Documentation**](#api) | [:tada: **Example**](https://pqml.github.io/spring) | [:globe_with_meridians: **Internet modules**](https://www.npmjs.com/org/internet)
- Framerate-independant spring physics
- Small, < 1kb gzipped
- Control the spring with tension and friction
- Adjustable timestep for the physics solver
- `onStart` / `onStop` callbacks
- This lib was made to learn more about fixed timesteps and integration.
- It's a pretty basic Euler integration - not sure it will work for complex structures like spring chaining.
- If you need a rock-solid spring physics library, use [ReboundJS](https://github.com/facebook/rebound-js)

# Requirements
- ES6 Modules support
- Using a module bundler like Webpack, Rollup or Parcel
- [Native support from browser](https://caniuse.com/#feat=es6-module)
- From NodeJS with [esm](https://github.com/standard-things/esm)
