+ + +## Our projects + +As a preface, the work I do involves building systems for many companies. +It's like building a mini ERP, suited for the needs of each company. +We have a fixed amount of time to do it, usually 5-6 months, each project +usually has 2-3 person working on it, and there are multiple projects +running in parallel. + +And most of the apps are just CRUDs. + + +## Our definitely (wrongly) overengineered tech stack + +Since we start new projects every 5-6 months we have the opportunity +to use brand-new technology. If the project I'm currently in didn't start +2 weeks ago, we would've been using Nextjs 15, which was released last +monday. + +So, what is our bleeding edge web stack for building CRUD apps? + +### Split back/frontend + +Welcome to 2017. We split those and communicate between using JSON. +However (at least in my project) we were all involved. I worked on +backend and front, my colleage 1 does too, and colleage 2 worked +both but it looks like they will be doing only front-end. + +But what is more weird about this split is: + + +### Nextjs for the **frontend** + +We use Nextjs, a full-stack framework, as a front-end only thing. +We generate a static bundle and ship it along our backend. + +How ironic that we use React Server Components, but those end +up being statically rendered. + + +### Redux (toolkit) + +Again, welcome to 2017. We have all our endpoints as global state, +managed with mutations and queries. + + +### tailwind, shadcn, etc + +Other less controvertial things are tailwind for styles, +shadcn for premade components. The small things. + + +### Nestjs (typescript) for the backend + +REST APIs written in JavaScript. + +I gues this wouldn't be that bad, except for the fact that +JS is a trash language (fight me), and we could use something +better. + +I'm not asking for Rust. I'm not even asking for Go. But can +we please use dotnet or java? + +On the topic of backend, we use Prisma as an ORM. Personally, +I rawdog my SQL, so I don't know about the latest and greatest +ORM technologies. But something I will say is that, to create +a user and assign it some roles, Prisma generated and executed +47 SQL queries. Something to think about. + +--- + +All of this, to render tables, forms and buttons. We don't need +any fancy interactivity. At most, we need some polling to get +the most up to date data. + + + +## Security? Never met her. + +The stack might be overengineered, sure, but is it wrong? +These are preferences, see, we could replace Next with Svelte +and Nest with Go and it would be the same right? Right? + +I think the problem of modern webdev is that we have prioritized +moving **blazingly fast** over anything else. We take a lot of +technologies that are **blazingly fast** to develop with on small +apps, that when composed together, become a mess to mantain. + +Because with this structure and only 3 CRUDs, the frontend already +has like 30 `.ts` and `.tsx` files for all the complexity. And, +ironically, the thing is so big that is fragile. + +But I know that something is fundamentally bad when things like +the following happen. + +What motivated to write this post was something the lead told me. +We have a manual implementation of RBAC on the backend. But, +no API endpoints check for permissions (authorization). All they +do is check for credentials (authentication). So, the conversation +went something like this: + +> Me: Hey, I was looking at the endpoints and noticed that +there are no checks for authorization. Any user with any role +with any permission can do anything, as long as they are logged in. +Am I missing something? + +> Lead: Right. We don't do that. I thought we could just check those +roles and permissions in the frontend, and disable some buttons +or hide them. That should be enough. + +> Me: But, you know we must also secure the backend right? We can't +rely on ui checks, anyoune can send an http request, and those +should also be secure, right? + +> Lead: Nah, I don't think it's worth the effort. If we also work on +security on the backend we will miss our deadlines. Disabling and +hiding buttons in the frontend should be enough. + +> Me: ๐คจ๐๐คฎ๐ซ + +to be continued... + + +
