> A blazing fast static files-serving web server powered by [Rust Iron](https://github.com/iron/iron). :zap:
**STATUS:** This is the WIP v2 release under **active** development.
For stable release v1 and contributions please refer to branch [1.x](https://github.com/joseluisq/static-web-server/tree/1.x).
> A blazing fast static files-serving web server. :zap:
**Static Web Server** is a very small and fast production-ready web server to serving static web files or assets.
## Features
- Built with [Rust](https://rust-lang.org) which is focused on [safety, speed, and concurrency](https://kornel.ski/rust-c-speed).
- Memory safety and reduced overhead of CPU and RAM resources.
- Blazing fast static files-serving thanks to [Rust Iron](https://github.com/iron/iron) and [Hyper](https://github.com/hyperium/hyper).
- Suitable for lightweight [GNU/Linux Docker containers](https://hub.docker.com/r/joseluisq/static-web-server/tags). It's a fully __4MB__ static binary thanks to [Rust and Musl libc](https://doc.rust-lang.org/edition-guide/rust-2018/platform-and-target-support/musl-support-for-fully-static-binaries.html) (`x86_64-unknown-linux-musl`).
- Gzip compression on demand via [accept-encoding](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Encoding) header.
- [Partial Content Delivery](https://en.wikipedia.org/wiki/Byte_serving) support for byte-serving of large files.
- [Cache control headers](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control) for assets.
- Memory safety and very reduced CPU and RAM overhead.
- Blazing fast static files-serving powered by [Warp](https://github.com/seanmonstar/warp/) `v0.2` ([Hyper](https://github.com/hyperium/hyper/) `v0.13`), [Tokio](https://github.com/tokio-rs/tokio) `v0.2` and a set of [awesome crates](./Cargo.toml).
- Suitable for lightweight [GNU/Linux Docker containers](https://hub.docker.com/r/joseluisq/static-web-server/tags). It's a fully __5MB__ static binary thanks to [Rust and Musl libc](https://doc.rust-lang.org/edition-guide/rust-2018/platform-and-target-support/musl-support-for-fully-static-binaries.html).
- Opt-in GZip, Deflate and Brotli compression for text-based web files only.
- Compression on demand via [Accept-Encoding](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Encoding) header.
- [Cache Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control) headers for assets.
- [HEAD](https://tools.ietf.org/html/rfc7231#section-4.3.2) responses.
- Lightweight and configurable logging via [tracing](https://github.com/tokio-rs/tracing) crate.
- [Termination signal](https://www.gnu.org/software/libc/manual/html_node/Termination-Signals.html) handling.
- [HTTP/2](https://tools.ietf.org/html/rfc7540) + TLS support.
- Default and custom error pages.
- [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) support.
- [HEAD](https://tools.ietf.org/html/rfc7231#section-4.3.2) responses support.
- [TLS](https://www.openssl.org/) support via [Rust Native TLS](https://docs.rs/native-tls/0.2.3/native_tls/) crate.
- Lightweight and configurable logging.
- Configurable using CLI arguments or environment variables.
- First-class [Docker](https://docs.docker.com/get-started/overview/) support. [Scratch](https://hub.docker.com/_/scratch) and latest [Alpine Linux](https://hub.docker.com/_/alpine) Docker images available.
- Server configurable via environment variables or CLI arguments.
- MacOs binary support (`x86_64-apple-darwin`) thanks to [Rust Linux / Darwin Builder](https://github.com/joseluisq/rust-linux-darwin-builder).
- Additional HTTP redirect server for redirecting HTTP traffic to HTTPS site.
## Releases
Available for download/install via following methods:
- **Docker Image** on [hub.docker.com/r/joseluisq/static-web-server/](https://hub.docker.com/r/joseluisq/static-web-server/)
- **Release binaries** for `GNU/Linux` and `MacOS` x86_64 on [github.com/joseluisq/static-web-server/releases](https://github.com/joseluisq/static-web-server/releases).
## Usage
Server can be configured either via environment variables or their equivalent command-line arguments.
### Environment Variables
### Command-line arguments
CLI arguments listed with `static-web-server -h`.
```
static-web-server 1.10.0
A blazing fast static files-serving web server powered by Rust Iron
USAGE:
static-web-server [OPTIONS]
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
--assets <assets>
Assets directory path for add cache headers functionality [env: SERVER_ASSETS=] [default: ./public/assets]
--cors-allow-origins <cors-allow-origins>
Specify a CORS list of allowed origin hosts separated by comas with no whitespaces. Host ports or protocols
aren't being checked. Use an asterisk (*) to allow any host [env: SERVER_CORS_ALLOW_ORIGINS=] [default: ]
--host <host> Host address (E.g 127.0.0.1) [env: SERVER_HOST=] [default: [::]]
--log-level <log-level>
Specify a logging level in lower case [env: SERVER_LOG_LEVEL=] [default: error]
--name <name> Name for server [env: SERVER_NAME=] [default: my-static-server]
--page404 <page404>
HTML file path for 404 errors. If path is not specified or simply don't exists then server will use a
generic HTML error message [env: SERVER_ERROR_PAGE_404=] [default: ./public/404.html]
--page50x <page50x>
HTML file path for 50x errors. If path is not specified or simply don't exists then server will use a
generic HTML error message [env: SERVER_ERROR_PAGE_50X=] [default: ./public/50x.html]
--port <port> Host port [env: SERVER_PORT=] [default: 80]
--root <root>
Root directory path of static files [env: SERVER_ROOT=] [default: ./public]
--tls <tls> Enables TLS/SSL support [env: SERVER_TLS=]
--tls-pkcs12 <tls-pkcs12>
A cryptographic identity PKCS #12 bundle file path containing a X509 certificate along with its
corresponding private key and chain of certificates to a trusted root [env: SERVER_TLS_PKCS12=] [default: ]
--tls-pkcs12-passwd <tls-pkcs12-passwd>
A specified password to decrypt the private key [env: SERVER_TLS_PKCS12_PASSWD=] [default: ]
--tls-redirect-from <tls-redirect-from>
Host port for redirecting HTTP requests to HTTPS. This option enables the HTTP redirect feature [env:
SERVER_TLS_REDIRECT_FROM=]
--tls-redirect-host <tls-redirect-host>
Host name of HTTPS site for redirecting HTTP requests to. Defaults to host address [env:
SERVER_TLS_REDIRECT_HOST=]
```
## TLS/SSL
TLS/SSL support is provided by [Rust Native TLS](https://docs.rs/native-tls/0.2.3/native_tls/struct.Identity.html#method.from_pkcs12) crate which supports [PKCS #12 cryptographic identity](https://en.wikipedia.org/wiki/PKCS_12).
An identity is an [X509 certificate](https://en.wikipedia.org/wiki/X.509) certificate along with its corresponding private key and chain of certificates to a trusted root.
For instance, identity files (`.p12` or `.pfx`) can be generated using the [OpenSSL SSL/TLS Toolkit](https://www.openssl.org/docs/manmaster/man1/pkcs12.html):
Generate a self-signed certificate (optional):
```sh
openssl req -x509 -newkey rsa:4096 -nodes -keyout local.key -out local.crt -days 3650
```
Generate a PKCS #12 indentity file (using an existing certificate and private key):
```sh
openssl pkcs12 -export -out identity.p12 -inkey local.key -in local.crt -password pass:my_password
```
## Docker stack
Example using [Traefik Proxy](https://traefik.io/):
```yaml
version: "3.3"
services:
web:
image: joseluisq/static-web-server:1
environment:
- SERVER_NAME=my-server
- SERVER_HOST=127.0.0.1
- SERVER_PORT=80
- SERVER_ROOT=/public
# NOTE:
# For the server, assets directory is not relative to root.
