Typescript (nodejs) backends are not performant, and your ultra modern stack is going to just cause you issues going forward if you need to scale. Prisma is really bad too, slow queries and no flexibility. If you ever need to do any sort of complex query you will just have to write sql anyway. And typescript is only sort of static typing. These technologies are great for prototyping and building a v1 release to see if what you're trying to achieve is actually possible, but you will regret it later on. The reason I know this, I work at a startup where we literally had the same backend stack and its been nothing but preformance issue after preformance issue. And it all needs to be replaced. We would have been better off building everything with go/rust in the first place. Or even java.

i don't agree at all. nodejs backends are as performant as you build them. the whole premise of node was async io, so if you're doing a bunch of blocking stuff then yeah, you're going to have issues. otherwise there's nothing innately non-performant about the platform. it's impossible to debate more without going into details on your performance issues. typical backend architecture for any platform these days is the scalable container model, if you wanted scale-to-zero i wouldn't necessarily use node because of cold starts. prisma can be great, can be slower than writing your own query, but that's the whole point of it. most of the time, it works and you can forget about queries and typings. when it doesn't, you can just eject to raw sql anytime you want. i'm not a total nodejs fanboy, and have used more jvm (java/kotlin/scala) in my life, but if i was building a web-app today i'd absolutely consider node for all the reasons the author listed

  Nodejs backends are not "as performant as you build them" nodejs is slow! This is an undeniable fact. If you ever have to do anything computationally intensive, which every backend at some point will nodejs will become the bottleneck.

    It's as fast or even faster than Java that you mentioned. In my experience, comparable to Golang.

      What do you think about how well uWebSockets.js performed in the TechEmpower benchmark? Just js is admittedly experimental, but it has the fourth highest score, and the highest score of any non-Rust framework as well which I found interesting. Elysia (a Bun framework) did pretty well too. Deno would have probably scored well too (it uses Rust's Hyper crate under the hood), but they're only running a single instance of the server despite Deno supporting the Linux SO_REUSEPORT socket option, which is important because the test is run on three servers with Intel Xeon Gold 5120 Processors that have 14 cores and 28 hyperthreads [0].

throwaway60330 2y ago
Node.js backend performance is comparable to Java. Perhaps you had bad developers - trust me, if they screwed it up so bad they wouldn't be able to make your Java backend any faster, and probably couldn't get Go or Rust to work at all.
- kyruzic 2y ago
  Go is perhaps the simplest language to learn there is. It's almost impossible to not get it to work because it has so few things you can actually do. And nodejs only preforms well in hello world benchmarks, real world applications are nothing like that. Once you start having to manipulate large arrays or do any large amount of math nodejs preformance goes into the dumpster.
  - speedgoose 2y ago
    I have never seen a glorified CRUD backend suffering from array or math operations. What kind of backend are we talking about?
  - rlt 2y ago
    > Once you start having to manipulate large arrays or do any large amount of math nodejs preformance goes into the dumpster. We’re talking about web applications, no? You probably shouldn’t be manipulating large arrays or doing large amounts of math directly in your web application server. That should be isolated in some type of service or worker, which could be written in another language. Or maybe there’s a NumPy-like package for Node.js, I haven’t looked. The question then is where do you draw that line of using another language? It probably depends on your application, but I think Node.js is perfectly suitable for typical web applications backends.
    - Fire-Dragon-DoL 2y ago
      Any large query result in a large array, so I would disagree on that point. Web apps deal with fairly big data structures, if nothing due to orms.
kossTKR 2y ago
This sounds weird to me. What kind of scale / traffic did you have? Must be incredible read write heavy with millions of users? I'm saying this because i myself have, and lots i know, have launched production sites with 100s of thousands of users on ready-made stacks like, Laravel, Rails, Flask (Php, Ruby, Python). But it's my impression that these fall short on millions of users and enormous concurrent traffic, but then you're already at huge evaluation, years into your project, or have 200+ positions, ie. you've already refactored your project multiple times.
- kyruzic 2y ago
  That's why you shouldn't use slow backend technologies in the first place because you get to the point where you need preformance and it's impossible because your limited by extremely slow runtime you chose initially because it was flashy (not even easier to developer for) when you could have just chosen something better from the start. Simple crud apps can get by fine with those technologies, but in the future I'd still never use it because you're leaving huge amounts of performance gains on the table for virtually no benefit. I don't buy the argument that javascript is just easier to develop for because it's simply not. The js ecosystem is a disaster.
  - kossTKR 2y ago
    What kind of application are you talking about? I agree to a degree but we haven't run into performance issues with say 100k users, what traffic did you handle, what was the business case? Again sounds like you are running some complex math heavy operation like say a weather service, national taxi service with lots of pathfinding, a global gaming platform etc? Curious to know what exactly you are talking about here? Because normally you just outsource the "heavy stuff" to some remote API, service, etc. you can write in a hyper efficient language anyway.
  - bcaxis 2y ago
    Making stuff faster is relatively straightforward engineering. Optimisation is a favored past time of many engineers. Getting stuff that people value enough to pay for, to make money, is the hard part. Any friction you put into the value creation process because "optimizing for future problems" is just doing it wrong.

- brink 2y ago
  It's progressively typed because it has to coexist with untyped Javascript code and libraries.
  - rlt 2y ago
    Sure, but you can enable TypeScript options and institute lint rules prohibiting use of untyped code.
    - willsmith72 2y ago
      i love typescript, but that's still not the same as static typing. imagine a full stack typescript app with a blog type type Blog = { name: string } everything works fine until you decide to refactor "name" to title. you update the backend and typescript code and deploy the change type Blog = { title: string } user john never closes his browser and leaves your website open. he clicks on a new blog post. his client typescript expects a name, the server gives a title, and crash, "Cannot read properties of undefined". i still choose nodejs backends, but you obviously have to keep in mind it's not statically typed. same with "any", my coworker could take my blog and modify it. it's preventable, but with large teams and codebases still prone to error. (blog as any).title = { summary: 'blah', full: 'blah blah blah' }
      - rlt 2y ago
        TypeScript is definitely statically typed. It is not a 100% “sound” type system, but very few languages actually are (Haskell, Reason, etc) And in your example of loading data from a server, if you have appropriate lint rules set up your editor and linter will warn you when you pass “any” typed data (such as that returned by fetch’s response.json()) to something expecting another type. You can use something like zod or yup to validate the data is the type you expect before passing it the rest of your typed code, thereby containing possible type errors to a known location where you can gracefully handle it. This is a problem with any language that accepts typed data from an external system, certainly not unique to TypeScript.

Many companies are not throttled by server language performance. Performance in many cases will depend on your database, geolocation, and caching techniques over nodejs vs go. Nothing wrong with prioritizing developer experience.
- kyruzic 2y ago
  I do agree with this, but I'd argue the developer experience of nodejs with Typescript is far worse than that of rust/go
  - dboreham 2y ago
    Agree. JS/TS is not a good environment for large software projects maintained over a long period of time. I'm not 100% convinced Rust is either, yet. cargo seems to be a dumpster fire. Build tools generate TB of mystery disk bloat. Obsession with async... hopefully these issues can be resolved.
    - brink 2y ago
      > Build tools generate TB of mystery disk bloat. No, it's not TB, it's a few GB for small projects, and tens of GB for large projects. Rarely does a project ever get over 30-40GB. > Obsession with async... If you're going to want any amount of decent performance, you're going to have to deal with async. That's just the nature of IO bound applications.

Now you can point to at least one dev who has the skills your team lead was concerned about finding.

You wouldn't implement Postgres, Ceph, QEMU or the kernel in Node... But the CRUD part of most applications will be fine in "any slow language"
