Show HN: I vibecoded a 35k LoC recipe app

Impressive!

35 kLOC is quite a bit. I wonder how straightforward and maintainable this app ended up to be. This would require taking a look at the sources. While good Rails code tends to be very terse, frontend may be quite voluminous.

> I believe within a couple of months, when things like log tailing and automated testing and native version control get implemented

This sounds a bit too optimistic, especially around automated testing, but yes, eventually this all will be there.

> an extremely powerful tool for even non-technical people to write production-quality apps

But why would non-technical people would even think in terms of log tailing and version control, any more than they think about the gauge of wiring in their walls, or the kind of modulation their Wi-Fi device use? For really non-technical audience to make a good use of such tools, it won't just take the AI to be a competent coder. The AI should become a competent architect and a competent senior SWE to translate from the product management language to the software development language, without even surfacing it when not explicitly asked. It's going to be quite a bit of a challenge to make it work, and work about as reliably as with a human team.

Since I wrote the blog post, I actually added automated tests which Windsurf / Claude Code runs before committing any change. It saved me a lot of headaches when the LLM decided to make random logic changes for no reason.

by varelaseb

The LLM swaps out business logic without you knowing it? As someone who worries about determinism and doesn’t do much vibe coding, I am curious what’s going on here, thanks!

by myvoiceismypass

4/2/2025 at 6:58:56 AM

Absolutely, very often. It typically happens because it's trying to do more than you asked for.

Example scenario: you have a codebase that you iterated on with LLM, and it contains let's say 15 features with various implementation details. You continue tomorrow and want to make a small change to handle an edge-case. While making changes to one of the 3 required files, suddenly it will decide to also rewrite / "improve" other parts of the code that have nothing to do with your request, where pieces of previous logic will no longer exist - since it made 18 changes to the file, and there are 3 such files, good luck spotting it without thorough and detailed change review.

Also, if you made manual changes to generated code and than you ask it to add something to the code (within the same "conversation" / context, it will often replace your changes with how it originally wanted code to look like.

Not 35k lines, but there's one line that's about 48,000 characters long. So either they've intentionally obfuscated it, or chatgpt just churned out one long line

I think people will have to recalibrate on this. The LOCs do things that you otherwise would not do. Features and details that simply would not happen — because they are too code/time intensive for most projects. It just won't matter anymore.

> But why would non-technical people would even think in terms of log tailing and version control

They won't! They won't have to. The obvious good stuff that everyone thinks the AI tool should be able do, will just work, because the people building the tools, will mostly obviously focus on making them work.

That or we're completely ignoring principles like DRY and producing a head spinning amount of tech debt.

I can't really imagine producing that much code in that short amount of time and holding any amount of it in my head. I'd bet money there's code in there that does the same thing but different, leading to all kinds of little inconsistencies that make this code worthless in any serious context.

by __loam

4/2/2025 at 1:07:50 PM

I’m an old school coder. I haven’t vibed. I’m guessing the “who is going to maintain this” could only be another tool similar to what built it. I can’t imagine trying to get my head around that much code in a timeframe acceptable to someone demanding product. So are we headed to a place where everything is written and maintained this way or a lucrative future of having to get these things to work properly.

by turnsout

4/2/2025 at 3:49:01 AM

I also wrote a recipe simplifying website, so this is a fun project to see. Incredible work!

Probably the main value engineers have for a maintenance project is context. I wonder what happens when we fully cede context to the machines...

Today, I got a request at work for a feature ("let's offer coupons!") that I thought would take a week. That was until I found out that another engineer wrote most of the code last year, and it'd take him a day to dust off.

I'm totally onboard with, and grateful for, larger-scale experiments like this...thanks for putting the effort in. I wonder how well Cursor (or similar) would handle a situation in which large amounts of code are _almost_ being used. What if 3k LOC accidentally get duplicated? Can our automated systems understand that and fix it? Because if they can't, a human is going to spend a _long_ time trying to figure out what happened.

Over the next 18 months, I expect we'll hear a few stories of the LLM accidentally reimplementing an entire feature in a separate code path. It's a whole new class of bugs! :D

I have similar thoughts and I have come to conclusion that that's the beauty and the curse of this technology. If one relies too much on it - it's gonna be a curse. However, if technology is used with care - it's a beauty. Not only does it keep SWE jobs "secure" - it really helps a lot for those who know what they are doing.

I think in the end AI will be more advanced tool, but a tool nonetheless. Like methodologies and principles, good practises etc. - they only work if you use it with care and added thought and adaptation to your case. DRY it a great principle. But sometimes it's better if you repeat yourself. For one reason or another. And these are the the tradeoffs that human in the loop should be making imho.

I agree. When I read these articles on vibe coding I can't help to think that these guys are basking in the glory of the impressive maze they built around themselves. Of course running these things in production and having them reach the state of legacy code is an entirely different thing. Building a maze is one thing, having to run around it is an entirely different challenge.

It's like one of those world expos: everything looks fantastic, but the moment the event ends everything just crumbles.

Can you share what's your strategy here, like topup $2000 open ai account as kind of marketing expenses for users to try for free?

I have a paid subscription to Windsurf using Claude. I struggle to find much utility in terms of actually writing code. It spends a lot of time trying / retrying and glitching out. I'm sure in a couple of years it will be amazing (assuming a fundamental breakthrough isn't required) but it isn't quite there yet.

LLMs are super useful but currently, the primary use case is teaching, not doing. For this reason, I think ChatGPT is really just as good as an AI enabled editor (or both if you don't mind paying for two subscriptions).

by osigurdson

4/2/2025 at 6:38:10 AM

To correctly vibe code something useful, I find that I need to religiously give faith to the tool and forget all about SWE principles and best practices and instead treat it like a child who makes mistakes and corrections while the adult must not intervene or admonish too much but rather nudge it to right direction.

Also vibe code has a parallel feature, while the code is generating, you are also doing live review and correcting it towards right direction, so depending on your experience, the end product can be a bad mess or wonderful piece of creation and maintenance dream.

The issue with seasoned SWE is that, the moment a mistake(or bad pattern) is made, the baby is thrown with bath water.

For a tiered app like the one presented, 35k LOC is not really that impressive if you think about it. A generic react based front end will easily need a large number of LOC due to modular principle of components, various amounts of hooks and tests(nearly makes us 25-40% of LOC). A business layer will also have many layers of abstractions and numerous impl. to move data between layers.

The vibe code shines, when you let it build one block at a time, limit the scope well and focus. Also, 2-3 weeks is a lot of time to write 35k LOC. at start of any new project, LOC generation rate is very high. But in maintenance phase it significantly falls as smaller changes are more common.

by n_ary

4/2/2025 at 4:43:38 PM

I've had a bit more success on the front end as it is possible to see the results of a change very quickly. In fact I would prefer it to just auto-apply the changes and I would visually inspect. It isn't bad but the workflow is pretty slow. The resultant code is also very verbose - likely 3X more code than an experienced engineer would create (this is one part that I am certain will improve dramatically in time). While I do use this workflow, sometimes I feel like I am just being lazy as opposed to productive.

I'm just being honest. For my use case, I would be much better off if LLMs could just do everything.

by osigurdson

4/2/2025 at 8:12:56 AM

My experience matches yours.

Lots of apps are quite repetitive: for building APIs for example you generate one controller and the ask the app to generate more using the first ones as a pattern. For frontend you do the same for forms or lists.

Tests are often quite good, but I think they were already great even back in the first ChatGPT release.

With this strategy and the fact that some patterns are quite verbose (albeit understandable for an AI or a reader), it is quite easy to get to a big LoC while still maintaining consistency.

by whstl

4/2/2025 at 11:04:22 AM

> LLMs are super useful but currently, the primary use case is teaching, not doing.

For code? Autocomplete on steroids is the killer-app.

The other things the LLMs give me are prone to be over-engineered/overly verbose code or similar.

I went through a lot of "Why are you also doing $FOO then $BAR? Doesn't seem necessary if we skip them and do $BAZ which will make one or both of those redundant" and it responding "You're right! Lets use $BAZ instead".

And giving them code to make a small change to was pointless - they would often, but not always, make an incidental change far from the point where you asked for the change.

But autocomplete? That works just great and because I've already got context of the code I am writing I can check it in (at most) two seconds and move on.

I think you're missing the value of rubber-ducking with the chatbot on a fairly well-defined/well-known problem in a somewhat specific/novel scenario—this is the vast majority of software development being done today.

Depending on the situation this can be invaluable. If you're experienced in the domain you probably know generally what you need to do but you might get a better result by reasoning through the best solution with the constraints and requirements you have. Or maybe you missed something obvious when you write out the full context—which is a required step for getting a good output from the chatbot, and generally isn't a required step if you aren't explaining your approach to someone else and you don't want to be rigorous.

I actually do use ChatGPT for rubber-ducking, but in that context there is no (or very little) code. In a coding context, I've resigned myself to purely autocomplete-on-steroids.

The thing is, in the vibe-coding context (having the LLM write the code for you), I've had atrocious results across all of the popular LLMs.

I have very similar experience.

After seeing how people like Andrej Karparthy used vibe coding to generate applications https://x.com/karpathy/status/1903671737780498883?s=61 I realize that

you need to be clear on what you want the LLM to do break down the tasks and give byte sized tasks to llm to do specific thing and sometimes I had to tell it not go and change random files because it found the need to refactor them.

Full Disclosure: I'm building a LLM chat app for software developers and domain experts

> I struggle to find much utility in terms of actually writing code.

I personally feel you need to give up some control and just let the LLM do its thing if you want to use it to help you build. It honestly does a lot of things in a more verbose way and I've come to the conclusion that it is an LLM writing code for another LLM. As long as I can debug it, I'm okay with the code, as I can develop at a pace that is truly unreal.

I finished my "Recent" contexts feature in a half a day, today. Without the LLM, this would have taken me a week I think. I would say 98% of my code in the past few months has been AI generated. You can see a real life work flow here:

https://app.gitsense.com/?chat=eece40e2-6064-46d2-9bf1-d868c...

I truly believe if you provide a LLM with the right context, it can meet your functional specs 90% of the time. Note the emphasis on functional and not necessary style. And if *YOU* architecture your code properly, it should be 100% maintainable.

I do want to make it clear that what I am doing right now is not novel, but I believe most problems are not. If the problem is not well understood, it can be a challenge like my my chat bridge feature. This feature allows you import Git repos for chatting but I will probably need to rewrite 50% of the LLM code since the solution it built is not scalable.

Glad you finally found Claude Code useful, Tom ;)

On a more serious note: I've found that for debugging difficult issues, o1 Pro is in a league of it's own.

Claude Code's eagerness to do work will often fix things given enough time, especially for self-contained pieces of software, but I still find myself going to o1 Pro more often than I'd expect.

A coworker and I did a comparison the other day, where we fired up o1 Pro and Claude Code with the same refactor. o1 Pro one-shotted it, while Claude Code took a few iterations.

Interestingly enough, the _thinking_ time of o1 Pro led us to just commit the Claude Code changes, as they were both finished in around the same time (1 min 37s vs. 2+ minutes), however we did end up using some feedback from o1 to fix an issue Claude hadn't caught. YMMV

Is the key feature here just the voice control? I’m wondering what you feel is missing from other popular recipe websites/trackers, and why I would choose to use this over something with more care put into it.

Or, was this mostly just an exercise in engineering/testing AI?

The real problem of your website is that the recipes are AI generated.

You can't solve those issues by throwing more AI.. well maybe the second problem you can (AI images with later models are generally ok)

It's specifically designed for this kind of task. Don't forget to check out the examples folder, I use recipes as examples a lot.

by Yiling-J

4/2/2025 at 2:17:54 AM

I still haven't done the AI vibe coding, but I think I get a similar effect with the Conjure plugin for Neovim with Clojure.

Being able to type out and immediately execute it directly in the window, and even have your code replaced by the output, is kind of life-changing. It fundamentally changes the way you write code, like the REPL isn't just a quick way to test your code, but a direct helper to test the stuff that you right.

I did a project in Clojure recently, heavily using Conjure, and then my next project was in Rust. Rust has nice Neovim plugins as well, but it still kind of felt like a step backwards; I found myself reaching for the "automatically evaluate" keystrokes that don't exist on Rust.

It's a term to describe using an agentic LLM based assistant to write the majority of the code but without even taking the bare minimum of time to review the output. I laughed when people naively claimed that it was intended for proof-of-concepts only and would never be used in actual "production".

by vunderba

4/2/2025 at 4:13:57 AM

It's a newish term that I have understood to mean coding by letting the AI do nearly all the work, just telling it what you want done in broad strokes. If the code returned seems to "vibe" with what you're trying to do, then accept it.

Contrasted to AI assisted coding, where you would give much more detailed prompts with technical specifications, and read over every line to make sure you understand it before accepting a response.

In theory, vibe coding can let someone with very limited technical expertise build complete apps, so understandably a lot of people are excited by it.

In practice, it doesn't seem like we're there yet. But each new step in AI development leads to people trying again, and it's hard to deny that the results are getting better. I think we're at the stage of where AI image generators were a few years ago. Very much in the uncanny valley.

Actually it is booming. In bsky, X and Linkedin, I see another recipe/todo/budget management/profit tracking/SaaS starter template/landing page/people-to-follow-directory etc. being pumped out every single day. Before GenAI, this would be more like one partial feature per user every month, now post GenAI, entire product in weeks or even hours.

I believe, the indie entrepreneurs are making the maximum bang for the bucks with AI codegen compared to any other groups.

Nice work! I also made a recipe app, but after seeing the recipes people generated on yours, I'm choosing not to share it at this time.

Seriously though - vibecoding is great. Even better (or only feasible) as engineers who can dive in when we need to.

My app is iOS and I had never done any Swift. I do have AI generation but that was more of a fun afterthought. The main utility is extracting recipes from the web and having a synced shopping list that I can share with my wife.

I understand that this is just kind of a proof of concept exposition of AI capabilities, but I fucking hate it and it is emblematic of the kind of low effort drivel that is infecting the internet. This is totally unusable in every way possible. While technically impressive (that AI can make a pretty-ish and functional website) it is practically useless.

Also, the photos are some of the most un-appetizing, uncanny valley, shit I've ever seen.

by jstummbillig

4/2/2025 at 8:39:50 AM

It has some basic features that are 'in-house' like a login, everything else seems to be using third party API's. As per the longer article :

> Eleven Labs API for text-to-speech conversion

> streamio-ffmpeg gem for audio file analysis

> Active Storage integration for audio file management

> OpenAI integration for recipe generation

etc. I'm not saying it's not a fun excersize in 'vibe coding', I'm just very curios the quality of the code that was actually produced. Its my feeling project maintainability is something that will be a big pain point in the future is people are relying on these tools.. 35k LOC for this recipe app smells like that to me at least.

by bilekas

Perhaps this is 1998 again, when you could earn big money on creating a visitor-counter service, or a guest book service.

Perhaps, now is the time for a lot of smaller projects with AI, that will, in a few years, all be blasted off the market by big corporations and change in trends.

Always floored about the problems people think need fixing. The problem is not that you get your dirty hands on the iPad. The problem is that you want real recipes. You know, things people have actually cooked and found to be good. With real photos of how the result actually looks (instead of what an AI thinks it might look based on the description).

You might be lucky and find these for free someplace on the web. However, those LLMs that "vibecoded" this Rails app for you are now also used to flood the web with garbage recipes, so finding good recipes on the web will become much, much harder than it already is. I browsed through the recipes and could not find a single one that actually looks real, so at the moment, you are just adding to this problem. This is why people still buy physical cooking books. The good ones are made with sturdy, thick paper so that you can get your dirty hands on them. This is what cooking is all about. Only unused cooking books stay clean.

by farzd

4/2/2025 at 8:21:33 AM

My argument is: the problem is solved. The solution is called: books containing real recipes.

The "problem" people have is: yeah, I want those, but for free. But creating a cooking book is a ton of work and very expensive. You need to first find good, original recipes. Then you need to actually cook each of them to see if they are any good, at least once, sometimes several times to perfect the recipe. And unless you are a photographer as a side-hustle, you need to do this again and hire a professional to make good-looking photos of the result.

Printing the books is also expensive. Good cooking books need to have very good binding so that they can be flattened to show one page for a long time without disintegrating. The paper must be thick and the printing must be able to withstand stains and moisture without becoming unreadable.

by deng

4/2/2025 at 2:42:28 PM

I use a delivery service that packages the food and the recipe in a box. The recipe is 1 page long, on thick paper, and I have used it as temporary food storage when the cutting board gets too full.

Works like a champ. Pictures and everything.

As somebody who cooks quite a lot (for a diverse set of people), I have the opposite experience of what you describe (also I hate having to touch my screen while cooking).

The cooking book scene has been openly criticized for not actually trying the recipes, even before LLMs were a thing[0]. Regular cooking websites have always been somewhat unusable due to massive ads and fluff text because 1) SEO and 2) recipes are not copyrightable, but the fluff text is.

For quite some time I get my recipes directly from chatgpt, the instructions are very condense, they work quite well, and most importantly: It knows how to substitute ingredients. "My friend is vegan and allergic to heat-resistant soy protein" and it's going to adjust accordingly.

What the hell is the "cooking book scene"? You make it sound like some cabal of cooking book writers sitting in some basement, conspiring to lead people astray. Nobody is saying that all cooking books are great, of course there are loads of shitty cooking books, and of course you are free to criticize that, even openly if you dare. I somehow cope by buying the good ones.

My experience with LLM recipes is like with pretty much everything else these things generate: usually very mediocre, mixed with glaring errors in between. If you are an experienced cook, you'll be able to manage since you'll recognize the errors.

by deng

4/2/2025 at 1:51:02 PM

In another comment, you say photos are required. I would claim that the cooking book scene is the publisher interest in the limited shelf space for photo-heavy cookbooks. Celebrity and TV chefs thoroughly represented.

Books without photos (McGee, Hewitt, Potter, Julia Child) are not interesting to publishers.

by ttyprintk

4/2/2025 at 2:08:03 PM

So you're allegedly annoyed with untested recipes and decided to solve this problem with a tool that only generates untested recipes? You're happier to cook or bake something from a wall of text that wasn't authored by anyone with any amount of culinary experience, that nobody has ever read before, attempted to replicate, or publicly critiqued, why?

I don't buy it, that's going to be a strictly worse experience than trying out the first search result that has photos, is rated 4/5 stars or better and that has a few positive comments. You can always ask an LLM for substitution recommendations separately.

I'm convinced that people who complain about this don't use recipe sites very often. There are loads without any preamble, and many of those with narrative provide a 'jump to recipe' button. Even if it is a long article with no jump (rare), it's still not a big deal

by ChrisRR

4/2/2025 at 8:38:36 AM

I've got a shelf full of physical cookbooks -- The New Best Recipe, The Food Lab, an Ottolenghi book, On Food and Cooking, etc. I like them, I've read through all of them, I sometimes use them for inspiration.

It's rare that I actually cook directly from them -- usually, that'd be big and fancy stuff or stuff I'm very unfamiliar with; in both cases I usually take the time to cross reference whatever the cookbook says with additional resources from the internet.

ChatGPT, on the other hand, I frequently use when or before cooking (and I cook virtually every day).

It's great when I only have a vague idea based on stuff in the fridge; five minutes later I've got a checklist I can reference. If it hallucinates something that I flat out don't think will work or, much more likely, comes up with something that I don't want or cannot do for lack of ingredients or time or whatever, I'll tell it to adjust the recipe and it does.

It's also great when I feed it a couple of existing recipes (from real people) to compare and contrast and integrate and reformat in a way that's most useful to me, e.g. a tabular format, or scaled to a different serving size.

With all that said, the AI based recipe sites don't really do it for me, either. If I want to cook purely AI generated recipes, a chat interface works fine -- and probably better. What I really want is an AI tool that helps me curate my own recipe collection. E.g. I want to ask it "I'd like to make Ramen, how did I do it the last time, what were my notes" and when it's done I want to tell it "ok, this was fine, I decided to double the mirin and next time I'd marinate the eggs longer" and have it update the recipe.

by morsch

4/2/2025 at 7:51:07 AM

Is the project anything more than a (fairly elaborate I must recognize) 1 April joke? I agree with your point even on a more general level, amateur techies thinking to fix stuff which never needed fixing are nothing unusual. We "disrupt" the economy, the finances, housing and more, every day, while being barely legal and sometimes outright abusive to some part of the society, all in the name of the Saviour Technology. Is this just another example of "solutionism"? Or it's just me waking up grumpy and without coffee...

But yes, websites will now be filled with these low-quality recipes, and some might be outright dangerous. Cyanide custard should ring alarm bells, but using the wrong type of mushroom is equally dangerous and much more challenging to spot.

by oxfordmale

4/2/2025 at 10:54:44 AM

I don't know why everyone is so salty. It's like putting "vibecode" in the headline attracted the worst in people.

For context, I'm not a cooking geek or virtuoso. I enjoy it to some degree, but mostly it's just about having a nice, nutritious experience, in line with whatever my mood might be. I only ever measure things super accurately when I'm baking things in the bread maker (because it doesn't let you make corrections). For most meals, I wing half the measurements and time estimates.

In my experience, most "human recipes" are just random variations on some baseline. I hate looking for recipes on recipe sites, youtube, etc. There are food bloggers that are exceptions, but usually I'll just end up scrolling for a long time with just frustration to show for it. If I sort of know some of the ingredients I want to use, have some sense of the type of eating experience I'm going for, and I want a bunch of recommendations based on that, regular "human recipe" sites are not the answer.

90% of my new recipes come from ChatGPT, and that ratio is increasing. I just marinated some chicken based on a recipe it magicked for me. I asked for insights on mixing mayo and yoghurt in the same marinade, because I had leftovers of both. It gave me 5 or so diverse recipes, and I just picked the one that best fit my pantry and mood. I also asked it to convert the recipe from volume to weight, not to mention scale it for my specific quantity of chicken, which was super handy.

I find that ChatGPT is great at providing common sense instructions and approximations. It's absolutely awesome at clobbering together a meal from ingredients I tell it I have. I can have an actual dialogue about any of it, get all kinds of recommendations and insights. That's been very useful to me. I'd go as far as to say that recipe generation is one of the easiest real problems for an LLM to solve. Or, at least for the kinds of recipes I use.

I've done my share of recipes from Serious Eats, but they weren't particularly good. I was doing Breton galettes the other week, which are notoriously fiddly to get right. Serious Eats had a huge article about it, interesting insights, but their final recipe sucked, and I was trying to be accurate. Not only I failed to get the consistency right, the wheat-buckwheat ratio was nowhere near what you'd get in France. I say, write researched articles about what makes recipes work. I can read it, I can bounce my LLM off it. If it's a fiddly recipe, I'll have to fiddle with it no matter what. If I can have a conversation with an LLM about principles at work, that's much better to me than a bunch of "human recipes".

Also, I often have questions about alternatives or things I need advice on as I'm preparing food. I'll also look at the recipe a gazillion times to check the instructions, quantities, etc. I'll set and check a timer often too. A voice-assistant is the obvious answer to this, which I'll try at my earliest convenience.

Kudos to the author!

I am horrified that you've produced that much code in such a short amount of time.

Thanks for sharaing your journey, I have few observations

1. When I click on a recipe from home page it is maintaining the scroll position, so I am not seeing the top of the screen. Is this deliberate?

2. "Recipe Ninja was vibecoded by Tom in San Francisco." Will it increase of decrease trust in your system for users?

3. To remove AI changing random files, I use "Copy relative path" to tell AI which file to change (there is a keyboard shortcut too). Not fully vibe coding but can be useful for precision bug fixing.

Good luck with the project.

"Still, I was determined not to write any code ... I just sat laughing as the computer wrote code."

I can pop over to Midjourney and be determined not to draw a single line and "sit there laughing" as it draws the Mona Lisa in the style of Salvador Dali but with a turnip instead of a person.

How is this any different? What is ultimately notable about it? Did any of it make you a better programmer?

I'm always deeply impressed when people devote significant chunks of their time to achieving extraordinary results. I'm entirely baffled, however, that there's anything at all interesting about using an AI interface to build an AI interface to connect you to AI slop.

You could have spent 20 hours planting trees or doing some kind of community serivce, and the world would have been a far better place.

Programming is not art. In the end, nobody will care whether software was painstakingly hand-chiseled by humans in a dungeon or "vibe coded", as long as the result is good enough. (I'd argue that art will "suffer" from the same "problem".)

What is notable here is that someone is demonstrating that the systems are reaching a quality where this is possible.

By conventional metrics, if the job got done well enough in less time, yes, even if less skill is involved.

I don't know about that, Roller Coaster Tycoon is fondly remembered and sits on a special place culturally because it was written in assembly by a single person.

Programming is more art then anything since it's definitely not a science, nor is it mathematics or engineering.

It's similar in principle to architecture or interior design.

April fools day has messed with my ability to identify satire at this time of year. Let's look at the evidence:

Posting date: 2025-04-02T01:57:13 1743559033 <-- too late

LoC: 35,000 <-- That's a _lot_

Front page: "Elon Musk Dirty Pants", "Heroin Hashbrowns", "AI Slop Stew", "Sweet Tooth Delight Made with Human Teeth" <-- WTF?

This is a joke, right?

I mean I guess kudos to you for being creative and building something, even if its with the so-called vibe-coding. But LoC is not the metric I would use to describe any app I've built, or that I am building.

People are putting disgusting nonsense in there. Maybe add an AI review step to block that stuff. Let them do the whole recipe, then just block it.

The only obvious problem here is showing all of them publicly. Let people do silly things but only show the sensible ones instead of being user hostile by default with false positives

by maxlin

4/2/2025 at 9:15:00 AM

Leaving them public has the advantage that no one will think the site is serious, which will help them avoid the recipes that look okay but are poisonous.

How does one learn to vibe code

by brcmthrowaway

4/2/2025 at 6:15:37 AM

By practice. It requires some skill too, to constantly remove slop and keep the project from deteriorating. Usually by suggesting good architecture, asking for tests, and rewriting / cleaning up some bad code endlessly. Still much faster than manual development.

by brcmthrowaway

4/2/2025 at 9:37:56 PM

1. Download Cursor

2. Tell it to make you something

3. Get frustrated when it doesn't work

4. Think about how to revise your prompt

5. Repeat from step #2

This is great. Want to come demo it in the weekly EarthPilot.ai AI Playground tomorrow at 11est?

Http://earthpilot.com/play and then join at AnthonyDavidAdams.com/zoom at 11 for show and tell.

I’m making a non-fiction book writing agent and I’d love to better understand how you used function calling to navigate the website!

by ada1981

4/2/2025 at 2:19:34 AM

Basically you declare to the AI which functions (tools) are available for it to call: https://platform.openai.com/docs/guides/function-calling?api...

Then you handle those function calls in your javascript.

``` if (function_name === 'search_recipes') { const searchParams = new URLSearchParams();

      if (args.name) searchParams.set('name', args.name);
      if (args.difficulty) searchParams.set('difficulty', formatDifficulty(args.difficulty));
      if (args.min_duration) searchParams.set('minDuration', args.min_duration.toString());
      if (args.max_duration) searchParams.set('maxDuration', args.max_duration.toString());
      if (args.tag) searchParams.set('tag', args.tag);
      
      // Handle ingredients array correctly - the search page expects ingredients[]
      if (args.ingredients && args.ingredients.length > 0) {
        // Clear any existing ingredients
        searchParams.delete('ingredients[]');
        
        // Add each ingredient individually with the correct array notation
        args.ingredients.forEach((ingredient: string) => {
          searchParams.append('ingredients[]', ingredient);
        });
      }
      
      const queryString = searchParams.toString();
      const url = queryString ? `/search?${queryString}` : '/search';
      
      navigate(url);
      return;
    }
    
    // start_cooking function
    if (function_name === 'start_cooking') {
      // First check if we have an onStartCooking callback registered
      if (callbacksRef.current.onStartCooking) {
        callbacksRef.current.onStartCooking();
        return;
      }
    }
```

A cooking web app 35k LoC? Wow, the author might be surprised to know that an entire OS kernel can be programmed at a fraction of that count. I can safely say that the days where we compained about JS bloat can be put aside, this is a whole new league by itself.

Sane advice: learn to program, put the AI hype/drug aside and do yourself a favor. It's an invaluable lifetime skill knowing to program from scratch and perhaps unassisted coding will be a looked-after skill in the years to come.

I kinda wish I could look at the code, but it's not open source and the frontend sources are minified/obfuscated, but it's long and looks like it's using React and a css-in-react approach, which also generates a ton of code.

The term "vibe coding" gives me bad vibes, I feel that it is in some way an insult to my craft, the way a carpenter might feel about Ikea. But if only LLM's are going to read the code, the LoC aren't a big problem, increasing cost significantly less than if a real person would have to read it.

The two biggest issues I can think of with this approach is performance and security, with the first one only being a problem if you "make it", and the second one being too often ignored with or without vibe coding.

by bakuninsbart

4/2/2025 at 8:27:52 PM

I keep thinking of Visual Basic... It was scoffed at as not real programming... It was the drag and drop thing in the Visual Basic IDE that made it worse. Suddenly "anyone" could do it without really knowing programming. This new trend (if it is a trend) is sort of like drag and drop.

by fmxsh

4/2/2025 at 12:55:08 PM

That IKEA comparison is an awesome, perfect analogy of vibe coding as cheap shitty furniture.

- can't be maintained over time, gonna need to replace it

- mostly simple/basic furniture

- out of place in any existing environment

- easy to break (cardboard tables!)

Sometimes that's all you need though.

(1) It's incorrect to assume that the content published on HN benefits only the VCs, and none of the other participants.

(2) This particular post is an interesting data point in the research of what the current crop of LLM-based tools is capable of. It reads a bit like a Windsurf ad; I would like more details on how the technical side of the development panned out, what were the problems and where, how were they overcome, etc.

(3) The parent comment reads as a somehow funny mix of socialist "anti-greed" agenda and frowning upon the fact of sharing knowledge and experience freely.

It makes you want to... kilometers? I've heard of people "going postal" when they're angry, but I never heard of someone "going metric".

Less tongue-in-cheek: there's no word censorship in HN. You can say "kill myself" here.

You probably got downvoted because you admitted your failure of using the WWW. The problem you describe only happens on "recipe" websites that are 99% advertising and written like a blog, with every other word set in bold to maximize the ad revenue. These websites should be avoided entirely. Proper recipe sites include en.wikibooks.org/wiki/Cookbook:Table_of_Contents, based.cooking and of course https://web.archive.org/web/20110323153937/http://www.ottavi...
