The current version of JavaScript does not have support for string templates

Attempting to utilize ES6 String Templates in a Node.js (version 5.7.0) application, but encountering issues. Webstorm is alerting me that

The current Javascript version does not support string templates

I am positive I have successfully used string templates in a node application before. How can I enable string templates to work? The server is currently running with this command

npm start

Once the issue is resolved, how do I inform Webstorm that it has been fixed and prevent the warning from appearing?

Edit: I updated the application source code to incorporate template strings like so:

var app = express();
var server = app.listen(process.env.PORT || 8080, function () {
    var host = server.address().address;
    var port = server.address().port;
    console.log(`App listening at http://${host}:${port}`);

Upon execution, the application displays:

App listening at

Answer №1

JavaScript versions ECMAScript 6 and higher support string templates.

To resolve this issue in Web Storm:

Open the Webstorm IDE

-> Navigate to File

-> Go to Settings

-> Select Languages & Frameworks

-> Choose JavaScript

-> Set Javascript Language Version to

Select ECMAScript 6 instead of ECMAScript 5.1 or any earlier version.

If the code runs without errors, then the template strings are functioning correctly. However, if the output is not as expected, try using console.log to inspect your variables.

Edit: Regarding the warning in WebStorm, fixing it seems quite straightforward.
