is it necessary to install body parser?

[thinkerelwin]

First, this is a great video, thanks for putting so much effort into it.

I do notice some places that can be further improved:

on index.js,

• I think we can replace those two lines that use body-parser to be the following:

  app.use(express.urlencoded({ limit: '30mb', extended: true }));
app.use(express.json({ limit: '30mb' }));

  p.s. bodyParser.json() doesn't have an extended option

• The new recommend algorithm for encrypting is Argon2id now.

no u can use this instead,
app.use(express.urlencoded({extended:true}));
app.use(express.json({limit:'30mb'}));
