I am using Highcharts to create some charts, more specifically I am using https://github.com/highcharts/node-export-server in order to export the charts. A JSON file is used for the source of what the chart will contain(see JSON below).

I then read data from a file and want to replace the data property in the JSON file with what I read from the file, the problem I have is that the JSON contains a function() so when I use JSON.parse() it fails because a JSON cannot contain a function().

 "chart":
 "type":"bar",
 "labels":
 "style":
 "fontFamily":"Arial",
 "fontSize":"14px"
 ,
 "events": 
 "load": function() 
 var plotBands = this.xAxis[0].plotLinesAndBands;
 for (var i in plotBands) 
 var d = plotBands[i].svgElem.d;
 var dArray = d.split(" ");
 var rect = x:25, y:dArray[5], width: 540, height: 100;
 this.renderer.rect(rect.x, rect.y, rect.width, rect.height)
 .attr(
 fill: 'green'
 )
 .add();
 
 
 
 ,
 "xAxis":
 "categories":[
 "name":"Group A","categories":["Text A.1","Text A.2","Text A.3"],
 "name":"Group B","categories":["Text B.1","Text B.2","Text B.3"],
 "name":"Group C","categories":["Text C.1","Text C.2","Text C.3"],
 "name":"Group D","categories":["Text D.1","Text D.2","Text D.3"],
 "name":"Group E","categories":["Text E.1","Text E.2","Text E.3"],
 "name":"Group F","categories":["Text F.1","Text F.2","Text F.3"],
 "name":"Group G","categories":["Text G.1","Text G.2","Text G.3"]],
 "labels":
 "rotation":0,
 "style":
 "fontFamily":"Arial",
 "fontSize":"14px",
 "overflow":"justify",
 "textOverflow":"none"
 
 
 ,
 "yAxis":
 "min":0,
 "max":100,
 "title":"text":"y-values",
 "style":
 "fontSize":"14px",
 "overflow":"justify"
 
 ,
 "series":[
 "type":"bar",
 "name":"Score",
 "data":[20,20,43,80,20,10,65,88,35,62,48,85,63,20,13,54,34,100,23,55,76],
 "color":"red"
 ]

This is the code line that fails

var m = JSON.parse(fs.readFileSync('jsonFile.json', 'utf-8'));

Is there a way around this issue? Can I ignore the function in some way because I am not interesting in reading its content anyhow? Thanks in advance!

If the file is trusted you may use eval:

var m = (0, eval)("(" + fs.readFileSync('jsonFile.json', 'utf-8') + ")");

Anyway, I don't recommend you to do so.

You should either remove function and make valid json or change file to js, add module.exports = there and then use normal require on it:

var m = require('jsonFile.js');
