Show HN: Rust Web Framework

Hi everyone,

I've been "funemployed" for a few months and with all that free time and idle hands I wrote a full web framework (think Rails, not Flask) for Rust.

It's boring old MVC, has its own ORM, templates, background jobs, auth, websockets, migrations and more. If you're keen but don't feel like rewriting your app in a different language, Rwf has a WSGI server to run Django (or Flask) inside Rust [1], letting you migrate to Rust at your own pace without disrupting your website.

I think Rust makes a great prototyping and deploy straight to production language. Now it has yet another framework for y'all to play with.

Cheers!

I would kinda expect REST framework to be able to generate Swagger (aka OpenAPI) definitions out of the box. That's one of the killer features of FastAPI in my opinion.

Also, I don't really understand what is the reason for creating your own ORM instead of integrating with, let's say diesel.rs [0] and what is the reason for inventing your own template language instead of just picking one of the most popular existing template engines [1].

Other than that this project looks really interesting and I will definitely keep an eye on it.

I tried Diesel years ago, it was too "Rusty" for me. It made you define your schema twice, and couldn't use the same structs for inserts and selects (so 3 times, really). Overall, great first attempt at matching database types to Rust types, but the ORM needs to be more flexible and ergonomic - it's supposed to make writing queries easier, not harder :)

As for templates, writing your own language is almost a right of passage into 30s+ nerd club. I never read the dragon book, but I always wanted to take that class in school. There will always be different implementations of the same thing, and writing this one that mimics very closely what ERB (Rails) does felt right.

Same: I was put off by keeping track of models in triplicate, and the lack of automatic migrations. These are considered features, vice bugs; it's not for me.

I tried diesel about 5 years ago. I needed to do relationships where the foreign key lived on the other side of the relationship from what diesel wanted. IIRC diesel only supported the key on a specific side, I think it was a M:1 relationship. Diesel docs said this was unsupported. I was still learning traits at the time but navigating how to implement this in diesel was beyond me. I used sqlx and moved on.
