Rust http server boilerplate

Without any specific http framework

This is a simple code, written in Rust programming language.

New version (0.2.0)

Updated crates to :

hyper = { version = "1.2.0", features = ["full"] }
hyper-util = { version = "0.1", features = ["full"] }
tokio = { version = "1.27.0", features = ["full"] }

Disclaimer (was for 0.1.0)

I started to write it for my needs, and at the same time, I wanted to know how helpful it would be to develop with the help of ChatGPT4. Please note that I did not asked ChatGPT4 to write the whole code, it is too complex to do that. I only asked how to use the crates I wanted to use. I'll write a blog article on this as soon as possible.

Why ?

The main idea with this program is to be up to date with the latest version of all imported crates (as of March, the 29th, 2023).

I also wanted to write something light and as simple stupid as possible ! Thus there is no high level crates such as :

• Rocket
• Actix-web
• Warp
• Tide

All theses crates are mindblowing and I strongly recommand to use them. But this code is both for learning purpose and the felling of having fine grained control on the functionnalities.

Specs

• No specific framework for HTTP and routing : Hyper and Tokio only.
• Json support, both for encoding and decoding.
• Mysql support for SELECT / INSERT statements.
• Getopts to retrieve commande line parameters.
• Env_logger to log data with customized format.
• Toml to retrieve extra information from config file.
• Serves files from www directory, and specific 404 handler.
• All put in different modules. This might not be as clean as a whistle, but enough to understand how to proceed.

Todos

• Upload files
  • unzip files
  • image check and resize
  • qrcode
• MySQL SSL (for Azure)
• GraphQL support
• JWT - Json Web Token
• Password encryption
• Rate limiting and bandwidth control
• Ssl support
• Ability to send emails from templates
• Write a simple documentation explaining how all this works
• MongoDB support
• PostgreSQL support
• OpenAPI / Swagger support
• Request to another HTTP Server / REST / GraphQL
• Protocol Buffer
• Websockets
• name yours ...

How to use it

It requires a database. You must first prepare a users table with this :

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255),
    email VARCHAR(255) UNIQUE
);

And then copy the file config.toml.example to config.toml, editing your database parameters :

[database]
username = "your_username"
password = "your_password"
host = "localhost"
database_name = "your_database_name"

Then execute it thanks to cargo :

cargo r

That's it.

I hope this little code will help you.
