JavaScript Build a Simple Dynamic Site with Node.js Creating a Basic Template Engine in Node.js A Simple Merge Utility

how would you structure the first parameter of a function that merges and actual value to a template?

the template is wrapped in percentage (%) signs

index.js
var utilities = require("./utilities");

var mailValues = {};

mailValues.first_name = "Janet";

var emailTemplate = "Hi %first_name%! Thanks for completing this code challenge :)";

var mergedContent = utilities.merge(emailTemplate, mailValues);

//mergedContent === "Hi Janet! Thanks for completing this code challenge :)";

response.write(mergedContent);
utilities.js
function merge(content, values) {

    content.replace( "", values );
    return content;

}


module.exports.merge = merge;

Here's a few hints:

  • "The second parameter should be an object", so it wouldn't be directly usable by "replace"
  • "replace" could still be handy, but you'll need a loop to use it on each attribute of the object
  • you'll need to enclose each key in percent signs so they will match the template
  • you won't need to make any changes in "index.html"
