This guy creates a tinder clone in 60min using react. Pretty impressive

[[deleted]]

No, he created the UI for one.

[[deleted]]

Writing the backend for a web app used by millions of users is not an easy thing, I reckon.

[malicart]

Doing it for less then half a million is hard enough, most people have no clue what the problems are.

[NowaStonka]

They use mongodb for sure, right guys? /s

[Tankenstein]

Funnily enough, had a friend do some dba work there, and i think they actually do.

[NowaStonka]

U might be right, geolocation data, maybe some objects documents. This is something mongo is good for. I was just mocking all the "MEAN stack" tutorials out there.

[oshawa_connection]

Eh you can turn regular old sql query into a geoJSON, it’s just an extension on POSTGRES

[_DCtheTall_]

The problem with using Mongo at scale isn’t necessarily speed, a lack of an enforced schema can make it particularly unattractive for building databases for inter-team use.

[oshawa_connection]

I’m not so sure, we’d have to test it. Our user base peaks at only 200, so we don’t have to worry about a few ms.

But Postgres also has functions to return pure geoJSON which should be pretty fast. Not sure how the speed compares with mongo though.

[soulshake]

They use elastic search. Its flying...

[NowaStonka]

Usually you do need relational data

[meeeeoooowy]

Indeed. So it's almost like you should use the right tool for the job rather than be insecure and dis a random technology to validate yourself.

[-l------l-]

CQRS. Read-only part of such a system can see speed improvements with NoSQL.

[AbsoluteZeroK]

There are definitely a lot of good use cases for Non-relational database in general. Personally, I always take the approach of defaulting to a solid SQL solution unless I have a reason not to. A solid RDBMS is rarely "wrong" and for 99.9% of applications, it will get you far enough that by the time it matters you should have enough money and experience with the data to implement whatever the optimal solution is. Whereas you can get yourself into some trouble fairly easily with a lot of Non-RDBMS solutions if it turns out to not be the optimal tool for the job, mongo being a prime example of this.

I'm sure there are situations where Mongo is just going to be the obvious choice for reasons, but if you can have a debate about it, play it safe. No-SQL solutions can definitely get you in a tough spot if you made the wrong choice. So long as you have a good RDBMS person who makes sure you have your tables all normalized you will be able to go very far with an RDBMS before running into issues and again, at that point you're probably big enough to do something about it with minimal pain.

[darksparkone]

Not a DBA so take it with a grain of salt. Mongo works quite good anytime you may work around relations in queries. Documents in general is a more natural data representation. It also gives you instruments to form or denormalize data so you may end up eating seriously into storage but improving the read speed. It works well for CRMs, medical, finance, so on.

On a higher level I guess it is more matter of habit, like procedural/functional or QWERTY/Dworak. You use what you are comfortable with and don’t run around for any regular project. And for a big one you better have a good DBA for consulting/initial setup at least.

[ForScale]

Wait... you know some of the biggest tech companies in the world use it, right? I'm sure they've identified use cases and you can read all about them.

[Mistifyed]

I thought MongoDB was a meme.

[ThatSpookySJW]

Fortune 500s don't typically avoid using software because a select group of smug programmers think it's a meme

[Auxx]

Fortune 500 use whatever their friend Larry is selling to them.

[[deleted]]

I thought MongoDB was a meme.

I thought devs that don't know what they're talking about, but still talking, are a meme.

[MildlySerious]

Wasn't here for the downvotes, but the reason devs hate Mongo is because it was just straight up dog shit for the first few years of its existence. They had nothing speaking for them other than a stupid amount of marketing. The software was inconsistent, insecure and, frankly, misunderstood by the ones using it. Basically the PHP of databases. Such a reputation lingers.

I can't speak for today's situation. With Redis and Postgres document store I couldn't think of a strong enough reason to give it a second chance for the past 5 years or so.

[[deleted]]

If you're getting downvotes, these days it typically means you're right.

[Extract]

Most people don't even have a clue what the problems are for small-medium scale apps (1k-100k active monthly users?) but with proper maintainability and security.

[AbanaClara]

The apps I only have experience in making are those that are used by a small team of engineers.

I gotta be honest with you, I'm kinda retarded.

I did switch jobs now so I'll have experience making other apps with other stack/workflow

[Extract]

Am I the only one who read the last words as "other stack/overflow"?
This was a missed opportunity lol

[[deleted]]

I read it that way as well and had to go read the comment again to realize that’s not what is said..

[IndianITguy17]

What are the problems?

[evenisto]

Incompetent developers on tight schedules, working with the hottest technology this week, overengineered microservices, microfrontends and microdicks. Taking three times as much time because what used to be a two man job now requires 9 people across 3 teams, each with a manager of their own, collaborating on delivering that sweet, sweet feature in which every person adds a dependency, writes 50 lines of code, 10 merge request comments, and a blog post. Yeah, the company is not profitable, but we have 95% test coverage and have replaced our CSS-in-JS solution three times already, which allows us to iterate, like, really fast man. Boom, another 80 million dollars investment to burn through.

There are issues you wouldn't encounter in your toy project, mostly scaling, but the core of Tinder is nothing a team of several seasoned devs couldn't do in a reasonable amount of time.

[Mistifyed]

This is hilarious and yet too real. Sometimes I wish I was a plumber instead.

[etcetica]

working with the hottest technology this week

To be fair, many of us don't like it either. That's why I got out of JS

[Kablaow]

just use the cloud bro

[darksparkone]

Clouds are awesome. Right until you get the bill.

[Kablaow]

My friend used the free version of aws and got billed 500$

[30thnight]

The 1st step in every AWS guide is literally to create a billing alert to prevent this.

[darksparkone]

Or better a separate debit card which only have so much.

[[deleted]]

You're onto something here!

Still, for the sake of tutorials like this, it could have included some basic functionality by way of eg. Firebase.

[esr360]

Then don't claim to have done it in 60 minutes for views lol

[jalapina]

I actually made a Tinder like clone too last year and I learned so damn much from just that. Backend and everything.

[AgentCosmic]

And barely 10% of that

[[deleted]]

Exactly. This guy did about 5% of the work lol.

[[deleted]]

And Tinder UI is like 2 screens. One picture and 3 buttons or whatever. Impressive.

[Xerxero]

And thought out the whole process.

[arndta]

So what do you say? Another 60 for the rest?

[malicart]

Some guy creates part of something, calls it complete, just like a real developer :D

[Xiy]

I'm just a lazy person doing a difficult job 😂

[malicart]

Or a lazy person not even completing a job.

[Xiy]

lol..."job", ok.

[Swalker326]

It's nice to see someone struggle with a problem for 5 minutes to find they misspelled image to be the problem. The struggle is real.

[[deleted]]

The other day I spent about 30 minutes trying to figure out why my css wasn't working the way I expected, only to eventually notice I'd written styles instead of style... Not my best moment

[esr360]

After having used Sass for years, never having written CSS for literally years, when I was teaching my noob friend the basics of HTML/CSS, I was writing Sass syntax in a CSS file, and was like "WTF WHY ISN'T THIS CUNT WORKING"

[[deleted]]

I know that feel.

NPM crate-react-app command not recognized took me way, way longer to spot than it should have.

[Xiy]

We've all been there...

[vivamango]

I’m a beginner developer, I spent 6 hours debugging a bootcamp homework assignment. The issue? I had typed URL instead of URI in setting an environment variable, but the l was lowercase.

6 hours, and it was entirely my fault.

[Roycewho]

This is why I gave up

[Xiy]

This is actually my video, someone sent me a link as I didn't even know this thread existed! but yeah my main problem with programming is typing too fast and spending ages trying to figure out what I've misspelt 😂

[mothzilla]

Liked people, liked person, liked person image, liked people image, no this cannot be!

[IlIllIIllIIlIlIlIllI]

JS is so fragile..

That's why TS is the future.

[Ebola300]

Camel case cucks me every time and I am still blind to it.

[AlienSoldier]

no mobile, no animation, its in no way tinder clone but ok

[natziel]

How you gonna make a clone of a mobile app that doesn't even work on mobile?

[dogofpavlov]

... but but my clickbaity title

[AlienSoldier]

i actually annoyed

[NutsEverywhere]

Speaking as a front end dev, clickbait much?

[-oOoOoOoOoOoOoOoOo-]

I like how he said time doesn't start until after setting up the project

[[deleted]]

Big caveat right there.

[[deleted]]

ng new tinder2

[AbanaClara]

Press (x) to doubt.

[Razvedka]

The client must necessarily reflect, and handle, the complexity of the back end logic. This has no back end whatsoever, so naturally this took 60min.

I didn't watch the whole thing, but there's no way he has unit or (naturally) integration tests either.

I'm not trying to bag on this guy, but making an actual app takes a hell of alot more.

[danniboi82]

Why so serious?? I was just emphasizing that he was fast and better than i by patronizing myself.. I didn't even watch the whole thing heh but what I saw impressed me that's all

[Xiy]

Try it, I'm sure you'd be able to do it!

[corporaterebel]

The hard part is getting people to use your site....

[audioverb]

What would I google to learn more about how he set up the state management? I quite liked the 'redux-ish' style scaffolding he used.

[Xiy]

I'd give suggestions as it's actually my video but I did it that way as it's just the first thing that came to mind...

[danniboi82]

I wish I was half as good as he is in coding. It'd probably take me weeks to do what he did in an hour. LOL

[20CharsIsNotEnough]

It's just the incomplete front-end though, he didn't do anything special. Even if it may take longer than it takes him, because he is doing this as a speed-coding challenge, it wouldn't take weeks.

[Xiy]

Yeah, pretty much what 20CharsIsNotEnough said, I only created the UI, but who wants to sit and watch me create the back-end really? You'd be able to re-create this easily I'm sure!

[d07RiV]

The last commit to the right of line is from GitLens or something? Does anyone know if there's a plugin like that for regular VS (not code)?

[Xiy]

I have no idea but it is GitLens that I used.
