LeafHttp is a simple configurable web server.

⚠️ This project is for demo/educational purposes! It is *NOT* designed for production use.

• Configurable IP/Port binding
• Configurable WWW directory
• Optional path traversal protection
• Connection limiter
• Can serve simple HTML/JS/CSS/etc. files
• ⚠️ PHP is not supported (will be served as plain text)!
• POST handling 🛠

• ✅ Linux
• ✅ macOS
• ❌ Windows
  • Not supported due to home_dir using POSIX APIs.
  • This may be fixed in the future.

• The server strictly expects that requests are separated by \r\n. Using two newlines will cause parse errors (and thus 501s).
• Clients are handled on separate threads, so don't make max-connections too high (unless you have a ton of CPU cores).
• Only GET requests are supported.
• max-request-size counts the entire request, not just the body.
• The request body must contain valid UTF-8 characters. The server will respond with a 501 if you send a body with non-UTF-8 characters.

Every client is handled in a separate thread. When the connection limit is reached, the socket is immediately closed.

See default_config.yml.

Since home_dir depends on nix, you may get some linker errors.

If you get an error like ld: unknown option: --as-needed (especially on macOS), you can fix it by changing the linker. This can be done by creating a .cargo/config.toml config file, and specifying the following overrides:

[target.x86_64-unknown-linux-gnu] # macOS -> x86 Linux
linker = "x86_64-unknown-linux-gnu-gcc"

You'll need to adjust this to your needs.
