Search and replace all in javascript/nodejs

Question

My replace all function is as below, it is in commonHelper.js file

exports.replaceAll = function (find, replace, str) {
  return str.replace(new RegExp(find, 'g'), replace);
}

Then I do following

var commonHelper = require('./commonHelper');
var html_body = commonHelper.replaceAll('[[username]]', user_row.username, template_row.message_body);
html_body = commonHelper.replaceAll('[[forgot_pass_link]]', forgot_pass_link, html_body);

this is not properly replacing the [[key]] parts here. What should I change to fix this?

I had to replace special characters. My updated replace all function

exports.replaceAll = function (find, replace, str) {
  var find = find.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
  return str.replace(new RegExp(find, 'g'), replace);
}

You can use split and join as a replace all. This removes any issues with regex special characters messing up the find and replace. Example:

>> "[boo].blah.[boo].blah".split("[boo]").join("(scare)")

"(scare).blah.(scare).blah"

There is a replaceAll command in string module.

You might be able to use it like this in util.js:

var S=require('string');
exports.replaceAll=function(hay,rplfrom,rplto)
{
    return S(hay).replaceAll(rplfrom,rplto).s;
};
