Getting Started

Setup

• In your project directory, npm install spline-wrapper (NPM package site)

How to use SplineWrapper

• Import the component: import SplineWrapper from "spline-wrapper"
• Already have an existing Source and Layer components? Don't have them yet? Not an issue! 😉

<Map>
  <SplineWrapper>
    //Copy&Paste or Create your Source and Layer components here
    <Source data={data}>
      <Layer/>
      ...
    </Source>
  </SplineWrapper>
</Map

• Want to add arrows? Just ensure you have loaded and added the icon (Example: How to load & add an image 😁). Then, pass the icon's name to icon and set the position:

<SplineWrapper arrow={{
  icon:"arrow", // Pass the name of the loaded/added arrow image
  position:"start" // Can be either start, center or end
}}>
  ...
</SplineWrapper>

• Want curvy lines? Use lines props:

const lines = [
  {
    from:[51.5072, -0.1276],  // longitude, latitude
    to:[48.8566, 2.3522],     // longitude, latitude
    properties:{...}  // optional
  },
  {
    from:[48.8566, 2.3522],  // longitude, latitude
    to:[4.2105, 101.9758],     // longitude, latitude
    properties:{...}  // optional
  }
]

<SplineWrapper lines={lines}>
  ...
</SplineWrapper>

Notes 📝

• There is no control points prop (to control the curve level/intensity) available at the moment but might be added if lots of people need it
• Curves are only applied to lines generated from the lines prop
• Load and add icon image before passing the name to arrow prop
• The arrows are applied to every feature of type LineString (including those generated from lines prop)
• The arrow points to the direction of the line

• Since this is just a wrapper component, you should have almost full control over react-map-gl related uses

Enjoy!
