Classified-ads-48 VS domain-driven-hexagon

I posted before asking for help on Classified-ads-48 and got very nice PRs that kept me motivated and made me learn very nice techniques and features in the NodeJS ecosystem and in web dev in general.

ps: this ismy app (software engineer but new to web dev, so don't blame labelling it with big words x))

I have a web-app that I started when turning into web-dev after some data engineering.

You probably saw how I deal with DB in my app that I listed in the other comment. Easy, most drivers already offer Promise based queries. Either you implement your callback where you return results or error then route it. Or you wrap queries with an async function in it you await native "db.query" calls (As I said most of drivers support, you should await to make code simple in your DB middleware) and implement then and catch from the caller function. If you didn't see mine, check this: https://github.com/bacloud14/Classified-ads-48/blob/hacktoberfest_only_branch/lib/services/mongo_ops.js you don't need try catch in case your Driver offers Promises (I believe).

If you have a hint, I will follow up with test. If you want to jump on code, here is the file and here is the repo.

sexpress 😆 comes with a plethora of middle-wares 🚀 , I'm not sure if everything is set correctly. Application middle-wares are third party dependencies and could be in a bad order. You know how third parties could mismatch.

That's exactly where I am. My manager gave me these links, that cover a lot of those words the backend uses, so I can identify what they mean and how to use them. 1. For inspiration and concepts: https://github.com/Sairyss/domain-driven-hexagon 2. Suggested to read the documentation for nest.js. They apply such concepts I don't understand: https://nestjs.com/

Domain-Driven Hexagon - architecture (NodeJS code examples)

Can't use any frameworks or libraries? Seems like a terrible idea tbh. I can suggest this repo https://github.com/Sairyss/domain-driven-hexagon - read "modules" and "folder and file structure" sections for some suggestions on how to structure files using patterns like Modular Architecture, Vertical Slicing, etc. Make sure to read the attached links and check code examples.

This is a reasonable intro, furthermore it points out more resources if you would he interested: https://github.com/Sairyss/domain-driven-hexagon

I’ve recently refactored one of my key domains using nestjs/cqrs and was heavily inspired by this repository.

Not a big one, but explains how to combine architectures like clean architecture, domain-driven design, hexagonal, etc. https://github.com/Sairyss/domain-driven-hexagon

I strongly recommand this: https://github.com/Sairyss/domain-driven-hexagon

Here is an example codebase with architectural patterns described more in details: https://github.com/Sairyss/domain-driven-hexagon
