Crate static_web_server

Static Web Server (SWS)

SWS is a cross-platform, high-performance and asynchronous web server for static files-serving.

Considerations:

This crate was published to make it possible for users to embed SWS with ease instead of working around it via forks. For example, allowing users to turn off default features like tls and so on.

However, because the library is highly coupled with the SWS binary project at this point, users might be limited by the exposed APIs, implementations, missing functionality, or dependencies.

In the future, we will eventually plan to make SWS library independent from the binary project.

That said, if fine-grained control and flexibility are needed then you could want to look at other alternatives like HTTP libraries or frameworks.

Pre-compile binaries:

This is the official SWS crate. If you are looking for platform pre-compile binaries then take a look at static-web-server.net/download-and-install.

Overview

Static Web Server (or SWS abbreviated) is a very small and fast production-ready web server suitable to serve static web files or assets.

It is focused on lightness and easy-to-use principles while keeping high performance and safety powered by The Rust Programming Language.

Written on top of Hyper and Tokio runtime. It provides concurrent and asynchronous networking abilities as well as the latest HTTP/1 - HTTP/2 implementations.

It’s cross-platform and available for Linux, macOS, Windows and FreeBSD (x86/x86_64, ARM/ARM64) as well as Docker.

Features

• Built with Rust which is focused on safety, speed and concurrency.
• Memory safe and very reduced CPU and RAM overhead.
• Blazing fast static files-serving and asynchronous powered by latest Hyper, Tokio and a set of awesome crates.
• Single 4MB (uncompressed) and fully static binary with no dependencies (Musl libc). Suitable for running on any Linux distro or Docker container.
• Optional GZip, Deflate or Brotli compression for text-based web files only.
• Compression on-demand via Accept-Encoding header.
• Partial Content Delivery support for byte-serving of large files.
• Optional Cache-Control headers for assets.
• Termination signal handling with graceful shutdown ability and grace period.
• HTTP/2 and TLS support.
• Security headers for HTTP/2 by default.
• HEAD responses.
• Lightweight and configurable logging via tracing crate.
• Customizable number of worker threads.
• Optional directory listing.
• CORS support.
• Basic HTTP Authentication.
• Customizable HTTP response headers for specific file requests via glob patterns.
• Fallback pages for 404 errors, useful for Single-page applications.
• Run the server as a Windows Service.
• Configurable using CLI arguments, environment variables or a TOML file.
• Default and custom error pages.
• Custom URL rewrites and redirects via glob patterns.
• Support for serving pre-compressed (Gzip/Brotli) files.
• First-class Docker support. Scratch and latest Alpine Linux Docker images.
• Ability to accept a socket listener as a file descriptor for use in sandboxing and on-demand applications (E.g systemd).
• Cross-platform. Pre-compiled binaries for Linux, macOS, Windows and FreeBSD (x86,x86_64,ARM,ARM64).
