npm install flex-svg

API

const flexSvg = require('flex-svg');

flexSvg(SVGdata , options, callback)

SVGdata: string Buffer (SVG)
options: Object (directly passed to the xml2js.Parser options and the xml2js.Builder options)
callback: Function

callback(error, result)

error: Error if it fails to parse SVG, otherwise null
result: String of SVG without width and height attributes

const fs = require('fs');
const flexSvg = require('flex-svg');

fs.readFile('path/to/file.svg', (readErr, data) => {
  if (readErr) {
    throw readErr;
  }

  flexSvg(data, (parseErr, result) => {
    if (parseErr) {
      throw parseErr;
    }

    console.log(result);
  });
});

flexSvg.FlexSvg(options)

Return: Function

Create a function to which options are binded. This is more efficient way in the case when the program repeatedly runs flexSvg function with the same options.
