A simple static HTTP server, for learning and local development.

basic-http-server is designed for two purposes:

• as a teaching tool. It is a simple and well-commented example of basic axum, tower, tokio, and asynchronous Rust programming, with async / await.

• for local development. It serves static HTML content, and with the -x flag, provides convenience features useful for creating developer documentation, including markdown rendering with syntax highlighting, and directory listing.

The core server setup is contained in main.rs. Error types and HTML rendering are in server.rs. The developer extensions are in ext/, with each extension implemented as tower middleware.

When passed the -x flag, basic-http-server enables additional conveniences useful for developing documentation locally. Those extensions are:

• Rendering files with the ".md" extension as Markdown, with syntax highlighting for fenced code blocks via syntect. Supports Rust, Python, Java, Bash, Go, C, JavaScript, TypeScript, and many other languages.

• Listing directories when no "index.html" file is found.

• Serving common source code files as "text/plain" so they are rendered in the browser.

All rendered pages support dark and light mode, following the system preference.

This makes basic-http-server useful for the following scenarios:

• Previewing markdown content. Draft your README.md changes and view them locally before pushing to GitHub.

• Navigating to local documentation, including Rust API documentation. Just run basic-http-server -x in your project directory, and use the directory listing to navigate to target/doc, then find the crates to read from there (cargo doc doesn't put an index.html file in target/doc).

Note that basic-http-server is not production-ready and should not be exposed to the internet. It is a learning and development tool.

Install with cargo install:

$ cargo install basic-http-server
$ basic-http-server

To turn on the developer extensions, pass -x:

$ basic-http-server -x

Set a custom port with -p:

$ basic-http-server -x -p8080

Listen on all interfaces with --public:

$ basic-http-server -x -p8080 --public

To increase logging verbosity use RUST_LOG:

RUST_LOG=basic_http_server=trace basic-http-server -x
