express-session deprecated errors

[MarcRam]

using express-session "^1.17.3"

will give the following errors

express-session deprecated undefined resave option; provide resave option index.js:14:9
express-session deprecated undefined saveUninitialized option; provide saveUninitialized option index.js:14:9

to fix, edit index.js line 14 from

app.use(session({
secret: 'supersecret',
}))

to read

app.use(session({
secret: 'supersecret',
resave: false,
saveUninitialized: false
}))
