Why am I getting a syntax error on my node production server build but not my local build?
Question
I hope you can help me . i'm fairly new to node and am building my first node app.
I have built out an app in node.js. It works fine and as expected when running locally.
When trying to run it on our internal production server I get an error message.
It seems to take issue with the opening template literal tag. The file in question employs a simple module export function. I've stripped down the code a bit to make it easier to read. See below:
exports.templateModule = function(markup, edmData) { var template = `<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head></head> <body></body> </html> `; return template;
I'm using node version v6.11.0.
The production server is running on linux.
package.json file below incase it helps.
{
"name": "template",
"version": "0.0.0",
"description": "A simple tempate test.",
"main": "app.js",
"scripts": {
"start": "node app.js"
},
"dependencies": {
"ejs": "^2.5.6",
"ejs-lint": "^0.3.0",
"express": "4.15.2",
"glob": "^7.1.2",
"node-dev": "^3.1.3"
},
"repository": {
"type": "git",
"url": "https://github.com/heroku/node-js-getting-started"
},
"license": "MIT",
"devDependencies": {
"node-dev": "^3.1.3"
}
}
I'll provide any other information you need if I can.
Any help or insight would be much appreciated.
Thank you
Moe

Template strings were added in NodeJS v4.0.0 .
Node.js v4.0.0 contains V8 v4.5, the same version of V8 shipping with the Chrome web browser today.
This brings with it many bonuses for Node.js users, most notably a raft of new ES6 features that are enabled by default including block scoping, classes, typed arrays (Node's Buffer is now backed by Uint8Array), generators, Promises, Symbols, template strings , collections (Map, Set, etc.) and, new to V8 v4.5, arrow functions.
If you are using an older version of Node.js on your production server, please consider upgrading it to a more recent version.
