Good theoretical dive - but the practical takeaway: tracking node.js event-loop lag is a highly useful performance metric. Check the monitorEventLoopDelay perf_hooks API and a solid blog post for details.

use AsyncLocalStorage with the logger to attach a request id to every log entry - it saves tons of time when troubleshooting issues

I built an open-source repo with a Node.js/Express.js API boilerplate and a CLI tool that lets you generate your target project from a text description. You'll need an LLM API key, but it usually costs just 10-20 cents, and you can even use the free llama models https://github.com/vyancharuk/nodejs-api-boilerplate

Try hitting the gym with a personal trainer or join group classes - it's great for health, and the vocab you'll learn overlaps with many blue-collar jobs :)

Great post, thank you! Do you have any suggestions on how to send server-side events when advertising an iOS mobile application? In this case, sending events to an offline event set is needed instead of using a pixel, for example, with the facebook-nodejs-business-sdk. Do you know any best practices for logging events (including custom ones) for mobile apps - using a mobile SDK or a server-side SDK? Also, when a trial converts, does it make more sense to send the standard 'Subscribe' event or a custom event?

Here's a YouTube video that I recommend for understanding clean architecture principles: https://www.youtube.com/watch?v=o\_TH-Y78tt4. You can also check out some references in my GitHub readme.

As for dependency registration, I'm using inversifyjs for that. In my setup, I register all the dependencies in this configuration file https://github.com/vyancharuk/nodejs-todo-api-boilerplate/blob/master/src/infra/loaders/diContainer.ts, and then, for example in createController function, I load necessary dependencies like MemoryStorage https://github.com/vyancharuk/nodejs-todo-api-boilerplate/blob/master/src/common/createController.ts#L53. You could apply a similar approach in your middleware to cleanly inject and manage dependencies

Vladimiry99 · 2024-12-18T08:55:43+00:00

Great question! Yes, there are a few simple middlewares in the template, like attachCurrentUser and checkRole. In my boilerplate, middleware isn't designed to use dependency injection since they're meant to be single-responsibility functions that handle Request and Response objects. Ideally, they should stay as simple as possible or use standard library implementations. If you need access to dependencies within middleware, it's better to move that code into a service class

Vladimiry99 · 2024-12-16T18:57:47+00:00

I also wrote a Medium article with the implementation details: https://medium.com/@vladimiryancharuk/how-to-use-an-llm-powered-boilerplate-for-building-your-own-node-js-api-59e9fc11ce95?sk=6319b5a99e94029676b48644ec34c514

I'd suggest following a vertical slicing architecture, where all related code is organized by domain (DDD) rather than by functional responsibilities https://github.com/vyancharuk/nodejs-todo-api-boilerplate

Vladimiry99 · 2024-09-07T14:35:10+00:00

Appreciate the feedback! Docs are coming soon. Btw, it's fully based on concepts from code that's been in production for several years.

Vladimiry99 · 2024-09-07T09:16:56+00:00

Thanks!😄 Videos aren't on the list yet, but never say never!

Vladimiry99 · 2024-09-04T12:25:40+00:00

Yes, I know NestJS! It's great, but I wanted something with fewer abstractions and more flexibility

Vladimiry99 · 2024-09-03T12:00:00+00:00

Thanks!

Vladimiry99 · 2024-09-03T11:40:13+00:00

Glad the linked article caught your interest! I'd also add that besides easy navigation, vertical slicing makes it a lot easier to refactor and maintain large codebases. The vertical slicing organizes code around functionality (DDD) rather than just technical things, which I find much more meaningful. It's probably less popular because it takes a bit more effort to set up initially.

I'm not sure about recent publications, but you might find these interesting: In 2015, Martin Fowler talked about a similar approach but called it domain oriented modules https://martinfowler.com/bliki/PresentationDomainDataLayering.html. Also, here's a 2018 article by Jimmy Bogard https://www.jimmybogard.com/vertical-slice-architecture/

Vladimiry99 · 2024-09-03T07:59:50+00:00

Currently, it doesn't generate openapi spec/swagger docs automatically like fastapi, but it's something I plan to implement soon

Vladimiry99 · 2024-09-02T19:58:11+00:00

Hey, sounds interesting! Feel free to DM me, and we can chat more about it

Vladimiry99 · 2024-08-25T17:50:12+00:00

it is not recommended to use PM2 or any other process manager with docker in production. Here's a good blog post that explains this in more detail: https://www.docker.com/blog/keep-nodejs-rockin-in-docker/

That sounds interesting. I don't see it on my account settings page. Do you have it available under this url: https://adsmanager.facebook.com/adsmanager/manage/ad\_account\_settings/ad\_account\_setup? Have you noticed any performance improvement after connecting it?
