Tide (http-rs/tide) JWT Authorization Middleware

This Rust library offers a middleware for the Tide web server framework, focusing on API key authentication via JWT (JSON Web Tokens) using the tide_jsonwebtoken crate.

Features

Seamless API key validation using JWT.
Direct integration with Tide routes.
Efficient handling of protected and unprotected routes.

Quick Start

Add the required dependencies to your Cargo.toml:

[dependencies]
tide = "0.16" # Use the latest version
tide-jsonwebtoken = "0.1.0" # Use the latest version
async-std = { version = "1.12.0", features = ["attributes"] } # Use the latest version

Usage

Initialize the Middleware:

First, create an instance of the ApiKeyMiddleware:
```
let jwt = ApiKeyMiddleware::new("your-secret-key");
```

Set Up Tide Application:

Initialize the Tide application and apply the middleware to specific routes:

let mut app = tide::new();
app.at("/login").get(|_| async { Ok("Login route!") });
app.at("/name/:id")
   .with(jwt)
   .get(|req: Request<()>| async move {
        Ok(format!("Hello, {}!", req.param("id").unwrap_or("0")))
    });

Run the Server:
```
app.listen("127.0.0.1:8080").await?;
```

Error Handling

The middleware inspects the x-api-key header in incoming requests. If the JWT is validated, the request continues; otherwise, the middleware returns a 401 Unauthorized status. Potential error messages include:

API key missing: The request lacks the x-api-key header.
Invalid API key: The supplied API key (JWT) is not valid.
