Module not found: Error: Cannot resolve module 'tls' in...

I've ran the basic installation, but as soon as I import Gremlin

import { createClient } from 'gremlin';

I get the following errors:

ERROR in ./~/ws/lib/WebSocketServer.js
Module not found: Error: Cannot resolve module 'tls' in
...

and

ERROR in ./~/options/lib/options.js
Module not found: Error: Cannot resolve module 'fs' in
...

Am running it with webpack and the latest stable version of Node (7.4). Have also tried it with version 5.9, but still get same issue.

Any ideas?

Is your code ran client side ?

[danvoyce]

yep :) It says this works in Modern Browsers?

Thanks for sharing this. Can you try with v2.3.2 please? npm install gremlin@2.3.2 should do the trick (feel free to rm -rf node_modules/gremlin prior just to be sure). I published v2.3.2 a few days ago with a new version of ws so maybe this introduced backward compatibility breaking changes when using this library in the browser like the one you're mentioning here.

As @dragma pointed out, the issue is most likely related to the fact that your code is running in a browser. How do you bundle your code? Do you use Webpack or Browserify, or something else?

fs does not exist in the client since it's a Node.js core used for interacting with the filesystem. Some web bundler shim these dependencies, and it could require a bit of tuning to have gremlin-javascript work in the browser depending on how you bundle your front end code.

That did the trick! I was for a minute wondering if this was for server side only, based on those errors.

And yes, using Webpack.

Thanks!
