Flexible Polyline encoding

The flexible polyline encoding is a lossy compressed representation of a list of coordinate pairs or coordinate triples.

For a detailed description, please visit GitHub.

Sample usage

To encode a polyline:

import { encode } from '@here/flexpolyline';

// Define an array of coordinates
const coordinates = [
    [50.1022829, 8.6982122],
    [50.1020076, 8.6956695],
    [50.1006313, 8.6914960],
    [50.0987800, 8.6875156]
];

// encode the polyline
const flexPolyline = encode({ polyline: coordinates });

// The output should be the flex polyline "BFoz5xJ67i1B1B7PzIhaxL7Y"
console.log(flexPolyline);

To decode a polyline:

import { decode } from '@here/flexpolyline';

// Use "decode" to get back the coordinates from the sample above
const decoded = decode(flexPolyline);
console.log(decoded.polyline);
