Architecture

[Scttpr]

Hi, it would be nice to think of a design pattern for the API. As far as Actix-web does not provide a specific pattern, we are pretty free !

I suggest something classic based on an MVC Model :

.
├── controllers
│   ├── mod.rs
│   └── recipes.rs
├── helpers
│   ├── dummy_helper.rs
│   └── mod.rs
├── main.rs
├── middlewares
│   ├── dummy_validator.rs
│   └── mod.rs
├── models
│   └── recipe.rs
├── router
│   ├── mod.rs
│   └── recipes.rs
└── services
    ├── database.rs
    └── mod.rs

Some thoughts :

• main.rs is the Rust entry point, where we have to modules and so on. I'm for a module logic with light files like in Javascript but it does not seem to be the case in Rust.
• Rust 2015 syntax uses mod.rs to register modules in the crate, Rust 2018 allows to create a directory_name.rs in the root directory to register. I prefer to stick to the old way with everything related to the module in the folder, what do you think about it ?

To be more specific on described folders :

• controllers : obvious
• models : obvious
• router : obvious
• middlewares : obvious
• helpers : could be tools, utils. All self made utility code.
• services : All modules related to third party crates (database, logger, seriazile, etc.)

I have no idea how AP could lead to a mutation in architecture but I think it's important to take it into account from the beginning.

What do you think about all this ?
