simplify-2D is a high-performance JavaScript 2D polyline simplification library

If you need a 3D simplification library, check out microjs/simplify-3D.

$ component install microjs/simplify-2D
$ npm install simplify-2d

var simplify = require('simplify-2D');
simplify(points, tolerance, highQuality)

Returns a simplified array of points

• points - An array of points in the format: {x: Number, y: Number}
• tolerance - Optional number (defaulting to 1) Affects the amount of simplification (in the same metric as the point coordinates).
• highQuality - Optional boolean (defaults to false) - Excludes distance-based preprocessing step which leads to higher quality but runs ~10-20 times slower.
