In mongoose 5.x, instead of calling next() manually, you can use a function that returns a promise and use async/await syntax. Btw, you have great tutorials :)

[patapon]

your channel is always my go to whenever I don't understand anything

You are a life saver dude! Thanks for all you do for us nerdlings

[ching-tangwang]

U really did a great job on explaining these concepts! Appreciate your works as usual!

[destinlee]

mongoose middleware!!! Mind blown. Oh, how I love learning new things :-D

your react firegram project is awesome!, hope to see more projects on React and the PERN stack, :), thank you so much

Hello,

Just a simpler way to hash password.

Use a mongoose setter to hash password every time the value is set or updated.

On your schema, on the password field, a set key -> {... type: String, set: value => hashPasswordFunction(value), ...}

It easier, simpler and it is working both in creation or edition.

keep the good work bro, absolutely loved it simple and easy 🧡

[jomarkpangan]

Wow! TIL there's mongoose hooks. really useful since I always hash my passwords in the route itself. thanks shaun!

Interesting :)
What I understood, this time, is that — thanks to the asynchronous instantiation —, we can use middlewares to hook an event and make some pre- and post-processes.
It's a really useful way to learn all the advantages of these features (asynchronous + middlewares + hooks).
Thanks a lot.

Really loving this tutorial series, it came at the right time for me in my programming journey. I have found that it's best to simply watch your tutorials start to finish without taking notes, and then opening up the project file at the end from GitHub and seeing how much I remember. I know everyone's style is different, and this maybe a bit selfish, but i thought i'd suggest it anyway - as these are predominantly tutorials, it would be cool (at least for me :P) if there were more tutorial-comments in the code for us to refer to in future. I suppose I'm just lazy though. I should probably comment along the actual code as I watch. But might need to halve the speed. Where are you from? I can't tell if it's Manchester or more Newcastle-way. My dad overheard your voice and said 'bloody 'ell he should teach the masses with that voice' :D

So with combination of hooks can we make mongo db realtime as firestore?

[liferc]

can this keyword be use with arrow function? or is there better way for arrow function?

[prafulrane]

What should I do next
Can you make a pathway video to know how should we follow your playlist from your channel for every technology covered on your channel?

still waiting for Node with firebase from GOAT !!

[andromilk]

So if I understood correctly, when you call "const user = await User.create({ email, password });" to create a user, the "post" hook is afterwards called and when this hook calls the "next();" function, it returns control to the controller "exports.signup_post" for it to complete the rest of its code? (ex : sending the response to the client) Thanks

[reynandelizo]

I have a question how to pass the custome error from shema.post to routes and send it to the forntend

[robtangled]

Hello! Thx for your great videos. I'm having a problem with this: Once I create the post("save") hook, it fires in every creation of an instance of any schema. Not only the schema that I created the hook for. So, I have a postSchema, userSchema, subscriptionSchema, but the userSchema.post("save", fn(x, y)) hook fires when I create a new instance of postSchema or subscriptionSchema.
Any idea why this might happen?

[harsha]

When I use the "this" keyword it is returning null, does anyone know why?

Edit: just found out I cannot use an arrow function there
