Escape single quotes in JSON.stringify

Question

I know, I don't need it, but I think I actually do.

I want to have a valid JS code rendered by handlebarsjs before it is even rendered. The JS minification tools just minify valid JS files and minifying on the fly increases processing time. This is the JS handlebars code.

var stringsObj = JSON.parse('{{{ json stringsDataObj }}}');

As you see, the single quotes up-there make that line of code a valid JS code. The handlebars helper is:

function json(context) {
    return JSON.stringify(context);
}

And what's the problem? Well, some of the items in stringObj happen to have single quotes

stringsDataObj = {
  "str1": "I'm here",
  "str2": "You're there"
}

and when it rendes

var stringsObj = JSON.parse('"str1": "I'm here", "str2": "You're there"');

gives an JS error

Is there a way to escape also single quotes in JSON.stringify? I tried with a replacer function, but without success.

Solution 1

This should get the single quote to be displayed in the browser:

var final_string = JSON.stringify(context).replace(/[\/\(\)\']/g, "'");

Solution 2

I solved my issue with the following helper

function json(context) {
    return JSON.stringify(context).replace(/[\/\(\)\']/g, "\\$&");
}

I.e., the escape must be done after the stringification.
