Rust Warp backend server

This is a Rust Warp backend server prototype for the demo video below. I made it for a freelance client as a POF a few months before. I had a freedom to use the language for a backend server. So, I used Rust to prove myself that I can do it with Rust. If I have to do it again, I would use Python.

I share it because I have to send some private works for Rust working opportunity. If I have to, I prefer it to be an open source.

If writing Rust were easy and take less time, I would rewrite. You can imporve it yourselves with TODO list below.

The payload will be session.rs file.

How to test it

You can use $python3 dev.py or $cargo run --bin main or $RUST_LOG=debug cargo run --bin main to test a web server.

If you want to start simple, start with hello and hi apis.

You can also test other CLI commands with cargo run --bin name. Refer to Cargo.toml for that.

End points

I let CURL commands for each files in routes/ folder to help you test the end points. But, you can start with these first.

• Register a user

$curl -X POST localhost:8000/api/user/v1 -H "Content-Type: application/json" -d '{ "email": "random@email.com", "password": "password" }'

• List users

$curl localhost:8000/api/user/v1

• Login

curl -X POST localhost:8000/api/user/v1/login -c cookie.txt -H "Content-Type: application/json" -d '{ "email": "random@email.com", "password": "password" }'

• Update cash

$curl -X PATCH localhost:8000/api/user/v1/cash -b cookie.txt -L -H "Content-Type: application/json" -d '{ "amount": 100000 }'

• Buy a car

$curl -X POST localhost:8000/api/user/v1/car -b cookie.txt -L -H "Content-Type: application/json" -d '{ "price": 10000, "color": "red" }'

• List cars

$curl -X GET localhost:8000/api/user/v1/car -b cookie.txt -L

• Gamble with cash

$curl -X POST localhost:8000/api/user/v1/game -b cookie.txt -L -H "Content-Type: application/json" -d '{ "stake_amount": 10000, "car_id": null, "number_of_participants": 2 }'

• Gamble with a car

$curl -X POST localhost:8000/api/user/v1/game -b cookie.txt -L -H "Content-Type: application/json" -d '{ "stake_amount": 10000, "car_id": null, "number_of_participants": 2 }'

• Ranking

$curl localhost:8000/api/ranking/v1/game

• Delete a user

$curl -X GET localhost:8000/api/user/v1/logout -b cookie.txt -L

TODO

This was just a prototype to clone a function of a gambling website. It is far from perfect. I will include some lists that you can improve.

If you want working Rust code to reuse, refer to the Rust Full Stack repository.

• Proper error handling with thiserror and anyhow.

• Domain driven project design instead of the current group by function(models/, handlers/, routes/ etc) and remove utils/ and other unecessary ones. It was difficult to structure the Warp app this way.

• Extract common parts to functions.

• Find how to reuse SQLite connection or substitute it with Postgresql and reuse connection with lazy_static.

• Currently, error responses from Warp relevant code are not that relevant. It will be only worth doing that if you develop it with frontend part also.

• User session needs the timeout relevant code. You can find better solutions or use prebuilt ones such as Redis etc.

• Include tests for every possible routes instead of CURL commands.

• Remove every unwrap(); parts.

• Use trustable 3rd API for random number generation and other manual implementations etc.

• Use documenation features of Rust better.

I did code with it a few months ago so they are only what I can think currently instead of investing so much time to read all code again.

There are not many Rust web server examples. I wouldn't write this way again if the development were for myself. But, hope you can save the compile time with it at least.

Frontend part is up to you. You can implement it on your own referring to the example above.
