DateFormat.js SyntaxError: Unexpected token export

Using this with some Kubernetes PODS and one of the pods out of the blue gives me this error. It seems to come from the call on line 6. Have not changed anything was just doing a deployment on gitlab and noticed this POD said CrashLoopBackOff.
/app/config/auth.js line 6
var dateFormat = require('dateformat');
My nodemodules folder has the latest dateFormat.js from package.json
So not sure what the problem is. Does someone know how to fix it?

Was able to fix it by downloading an older version of dateformat. Nothing wrong with my code on the question its a simple problem with the library not the code come on.

Here I could make it work by using another version of this package,was working in the version 4.6.3, so I did:
npm i dateformat#4.6.3

Failure when initializing PouchDB

Here is my stack trace when attempting to launch my api side of my react - web app.
I have ran into this error multiple times but never seem to be able to fix it when it comes up again!
/Users/joshua_paulsen/Desktop/Jump-In-Final/api/node_modules/pouchdb-core/lib/index.js:1285
throw new Error('Invalid Adapter: ' + opts.adapter);

I had my db defined like this - const db = new PouchDB(
${process.env.COUCH_HOSTNAME}${process.env.COUCH_DBNAME}
)
the fix ended up being changing it to this.
var pouch = new PouchDB(${process.env.COUCH_DBNAME}, { adapter: "http" })

What is this syntax error ? (Testing Hapi.js)

I'm just trying to test Hapi.js and, whatever I code, I got this error :
node_modules/hapi/lib/server.js:145

^
SyntaxError: missing ) after argument list

Where does come form this syntax ...() => {... to make a function ?
What I did bad to use Hapi ?
Thank you very much

The syntax is called Arrow function. You use hapi 10 or later which requires node 4+, but you have an older version of node which doesn't support arrow functions yet. The solution is to upgrade your node version to 4 or 5.

Node.js Cannot find module 'tcp'

What is the problem? I found the source on the Internet, and the author, and the visitors also can run it...

Try require('net') instead:
$ node
> var tcp = require('tcp');
The 'tcp' module is now called 'net'. Otherwise it should have a similar interface.
> var tcp = require('net');
> $

Others are able to run, may be because they are using Node module when 'tcp' was there...
Now its called 'net', but its all the same thing no need of checking..
