Canvas JSON to SVG using Node

Following is the steps / procedure to convert fabric json to SVG / PDF using NODE js script without using browser.

1. Add the following node module packages in package.json
   npm install canvas@1.6.13, fabric@2.6, jsdom@9.12.0

2. Load the node modules in js

var fs = require('fs'),
    fabric = require('fabric').fabric,
    out = fs.createWriteStream(__dirname + '/output.png');

3. Read fabric js canvas json from local directory

let jsonstr = fs.readFileSync(__dirname + '/templates/8.json', 'utf-8');
let json = JSON.parse(jsonstr);

4. Create static canvas

var canvas = new fabric.StaticCanvas(null, { width: wh.width, height: wh.height });

5. Load the json in canvas and convert it as svg.

canvas.loadFromJSON(json, function() {

  //first render
  canvas.renderAll.bind(canvas);

  //save the canvas as SVG in server
  var svgoutput = canvas.toSVG();
  fs.writeFile("output.svg", svgoutput, function(err) {
    if (err) throw err;
  });
});

Other features that can be added is SVG to PDF using svg-to-pdfkit module.
