Making a payment will be so sexy...

[@hemanthkotagiri8865]

That card animation is hands down, the best one I've seen so far anywhere in payment auth pages.

[@developerfilip]

Wow! Thanks for that! - and it’s all Stripe components, contained in a form! 😄 Just very custom ☺️

[@yjawhar]

The risk is high because after the @, the server returns all matching emails by json, so the attacker can just gather those. Your service could be a method to just collect emails.

[@k2n3l]

Hey man, I'm always excited to see how people build their dreams software. Quick notes. 1. The login screen where you show an error message for when the email entered is already in use is classic case of over enginnering. You could've just had a email form for both login/sign up together. If the email is in the db, ask for password and if the email is a new one, ask user to create a password. 2. I love how awesome you're making the experience but I still think you could be working on parts that differentiate your site from others more than those parts which every site has like the auth pages and payment pages. I'd love to see how you build the actual amazing learning experience you wish to build. That'll also give you an mvp to start getting test users for.

[@developerfilip]

Hey!! Thanks for watching! So for the account creation, I know it could have been much simpler, and I guess you could call it over-engineering, but like you mentioned below, I am definitely trying to differentiate this site from others. This whole experience will continue thought the whole application, I will make sure to make every bit of this platform as special as possible :D I'm just making baby steps now, but the vision is there, I want to get the basics right first and nail them, and then I'll move onto the real fancy stuff!

[@thongbanguyen5716]

Hi Filip, regarding the database, I think it depends on the data structure that you want to store. With MongoDB, since it’s a schema-free db, it provides you a lot of flexibility to store data. It’s great to use MongoDB when you need to do a lot of query with your db. However, MongoDB is not as secure as other SQL dbs like PostgreSQL. If you care about consistency, security, and scalability in terms of transactions or queries, and you can create a relationship between different objects that you want to store in your db. PostgreSQL is the one to take. Anyway, it’s up to you to choose which db that you feel more comfortable to work with. Great works on the UI man. Keep going!

[@developerfilip]

I've worked with PostgreSQL before, I was actually considering using it. I'm familiar with building database models, I'm just scared with the concept that it has be planned beforehand - and the way the app works should be known - but I'm still unsure. I need to give this a little bit more thought, but I definitely want consistency and scalability to be a key factor here. Thanks so much for the advice!!

[@thongbanguyen5716]

@@developerfilip I see where’re you going. Another problem with MongoDB is that it gets very painful as your db gets bigger, especially for writes. I’ve read somewhere about a company migrating from MongoDB to Cassandra to achieve better scalability. I’ve never worked with Cassandra myself, but I think you could consider it for your backend.

[@Wittgenstein.]

Hey Filip! Since I have some some experience in angel investing for startups with decent exists I just want to tell you few things, that can be helpful. 1. Competition is for losers When you're entering such competetive market don't focus on UI, focus on your unique value proposition. Can your users do something essential they couldn't done before? Can they do something 10x faster, 10x less expensive, 10x better? What is the process you're going to change radically? Why has no one done this before? I think that in Edu-Tech there are generally 2 segments of customers: I-won't-pay-you type, which is generally learning from youtube, google and blogs, since nobody likes to change to new enviroments [trust, lack of content, need to learn new UI etc.] His best day in his life was when he discovered what adblock does. Internet bookworm, which has a lot of money, is treating learning as an investment and doesn't care about paying few bucks for exclusive content/courses. 2. Some ideas are better for small-business, not for startups. A real startup is a company that creates something 10X, magical solution that customers can't get anywhere else. 'Unicorn' term should be seen as in customers-with-problem eyes, not in investors who love buzzwords. There are millions of restaurants, but there are only few big companies like mcdonalds. A fake startup is a small business, that is struggling to take over 5% of their first sub-market selling the same shit in the same way that have been sold for yers at slightly better prices $50 -> $40, $10 -> freemium or with slightly better UI, UX or different non-essential functions. These businesses still can growth to 6-7 number income, but that's usually the ceiling. If you're determined to make 6-7 figures with this idea, you'll probably achieve it after few years. Especially when you'll focus on youtube marketing, since from what I can see- it's your passion. I hope this can help you, keep up your good work! :)

[@developerfilip]

First of all, thanks for taking your time to help me out. I really appreciate this. You have given me some things to really think about and look into when driving this forward. I will probably read it a few more times to make sure I’ve engulfed all the great tips and try to apply them. Thank you!!

While rate limiting make sure to keep in mind some people have long emails and they'll require more requests than others.

[@developerfilip]

Yup, it will be set to a larger amount of tries, a timely fashion, or I might just make it like the username input, that verifies on submission, which would allow the user to enter the whole email before trying (which I think would be best) 😜

[@baibhavanandjha]

Hey Filip, I hope you're doing well. I noticed here you said that you'll be using an IP-based rate limiting. I am a security researcher and please keep in that there is this attack that can be easily performed after getting a free AWS instance. It's called IP rotating which will easily bypass IP-based rate limiting. Also, about password brute force, it's okay to have a week rate-limiting system in terms of security as it will be virtually impossible (it will take way too much time making this attack impractical) if the password is more that 5 characters with AlphaNumeric combination. However, use a good rate limiting technique that doesn't rely on IP for the OTP (if you decide to use OTP)

[@developerfilip]

Hey! Thanks for this awesome advice. I've actually started reading up on different rate limiting techniques. Is there one in particular that you would suggest for my use cases? I'm planning to rate limit my login, and after a few tries introduce a reCAPTCHA, I decided it would be fine as it would only show after many quests are sent, I been made aware there is also an invisible reCAPTCHA that analyses user activity. Would you suggest I rate-limit each one of my API endpoints? I mean, it seems logical to secure every API endpoint from being taken advantage of. What do you think?

[@ifbasit]

You are doing so well so far. I am really excited to see how do you end up with this startup. I do have some suggestions: 1. You are implementing different logics for validation for your forms. It should have one logic & UX for validation throughout the website. 2. The Payment Card UI is so fascinating, but tbh it's not User-Friendly. You may use Stripe default card UI; people have already seen Stripe default Card UI on many platforms they are much familiar with. 3. Try to add right border to the labels in inputs, Currently when its onblur. It looks like Labels are actually the text written in the inputs

[@morveman_yt9567]

Sooo gooood !! Well I think it hard to understand what you have to do with the card at first, but I LOVE the animation so much !!

[@developerfilip]

Thank you!! Looking at the awesome feedback so far, I will definitely make improvements to the UX of the card to make it clear as per what is going on! I have some ideas :D

[@farhanutk]

I think the current implementation might make the user think that it’s just a picture of a card. Maybe adding a border or background color to distinguish the input fields could help. It will be less confusing for the user.

[@developerfilip]

Maybe a flashing border and a message letting them know to fill out the card?

You could use tailwind within your SCSS with the @apply keyword so you won't have so many classes in the JSX files.

[@paulkouadio7623]

Yep. Test it out inline, and when you're satisfied with the end result just place the style in SCSS with @apply. Works like a treat

[@John-mj1kk]

You can do it like most other websites where if you've input your email/password incorrectly 3-5 times, it requires you to do a captcha for the rest of your tries. If, however, the tries exceed the limit, then the user will be restricted from trying again for a specified amount of time.

[@developerfilip]

That is exactly what I am planning to do! Thanks for the advice!!

For mobile screen I think you can flip the card and show the CVC field

Rate limiting can be bypassed via proxies, I would recommend doing rate limiting and recaptcha V3 (the user doesn't notice it)

Great series! I too am working on a SaaS app and am following along as I do. I wanted to comment on your database question: there is a third option. in my current app, I am using RDBMS, but with only one table for accounts and app state stored in a max-length string. Granted it's unusual but with good app-state management in place, it greatly simplifies my app, I have the benefits of indexing and throughput that come with a good RDBMS, and it still behaves like NoSQL.

[@rakaa31]

on mobile you can make that card small after completely filled and then add the same animation as laptop

[@weaslie]

At 17:55 you have different error messages for "user not found" and "invalid username or password". But this way someone can still bruteforce account names by checking the error message :) So make sure you use the same message when the user is not found or when the password is incorrect. Also I'm curious, GSAP requires you to buy their license when users have to pay on your website to use your website. Did you buy their license or do you think it's not necessary in your case?

[@developerfilip]

Great spot! Yes - I know I've introduced the error messages like that, I do need to change that, it was actually just to check if I meet all the conditions, but like you suggested, only one message will show! Great questions about the GSAP License - On their website it states "Our paid license is only necessary in projects that you sell to multiple end users". As this is a one of website, that does not require a user to pay to use it (it's only the courses that will be paid), I don't think this would apply to me. I will however double make sure with GSAP Customer Support before launching the courses. :D

[@weaslie]

@@developerfilip Thanks for your reponse! I'm having the same kind of issue with GSAP right now, because I'm building a website which partly requires users to pay (to unlock extra content). It has kind of the same use case as your website does, but as far as I understand I should buy the license since multiple costumers can pay on my site. So yeah.. Let us know when you find out :) Furthermore, keep up the good work! It's really nice to see you build up something from scratch like this :D Thanks for sharing it! Btw, the creditcard animation is sexy, as you said :) Only thing is that it's maybe not clear for all users that it contains input fields (like the CVC field). So maybe add some borders or something to make it more clear that those fields are input fields

[@blaizeW]

I'm a bit late, but - you shouldn't ask for CCV when you are adding the card on login. The CCV should be asked every time someone made a purchase. Also, your data should be encrypted.

[@developerfilip]

Hey! Everything is done via stripe, so all that data is being encrypted the way it should for max security. The CVV is required to add card details within stripe, and then whenever a purchase is made, the user has to provide the CVV again for security. Hope that answers some questions!

From my perspective I think relational db are the best suitable for ur project Why let redesign ur system U hv teachers students and admin maybe Teacher should have id , course number , name Student should hv name , id , boughted courses Ok obviously the PK( primary key for both is id (BCS it is not repeated name can be repeated. So we made the infra database design now if we go with nosql we can store them as obj but to relate them like how we could now the number of students with this teacher it will be hard because we need to recreate a new obj for this one metadata . But with SQL it will be easy because we can creat relationship btw student and teacher Teacher table id name courseNum Student table id name courseBght With simple query we can creat new table to the courseNum that had all the students IDs and the teach id Without using obj because on the future the no SQL it is gonna be so expensive for u if ur indexing all this data from an obj

Also, the series is amazing good luck with your job and startup :)

I understand what you mean and that you want to keep that mechanism with the email. However I don‘t want other people to know my email address, it‘s a brilliant idea really but you are technically exposing your users email addresses, even with a rate limit or a captcha.

You have to show the user that something is happening in the background, this results in a great UX even with a request delay
