$ component install microjs/simplify

var simplify = require('simplify');
simplify['2D'](points, tolerance, highQuality);
simplify['3D'](points, tolerance, highQuality);

Returns a simplified array of points

• points - An array of points in the format: {x: Number, y: Number} or {x: Number, y: Number, z: 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.
