svg-replace-bezier is a library for replacing bezier curves with line segments
This is accomplished by using svg-path-parse to parse the path, and using a portion of the antigrain geometry library compiled with emscripten to convert the bezier curves to line segments.
var replaceBezier = require('svg-replace-bezier');
replaceBezier.d('M100,200 Q100,100 250,200 Q400,300 400,200'); /* outputs 'M100,200 L100.146484375,....' */
npm install svg-replace-bezier
