* Add initial documentations * Update documentation for Basic Client and add WebSocket section * feat: add a static site generator with multi-language support - Introduced a new Rust-based static site generator in the `docs-gen` directory. - Implemented core functionality for building sites from markdown files, including: - Configuration loading from `config.toml`. - Markdown rendering with frontmatter support. - Navigation generation based on page structure. - Static file copying and output directory management. - Added templates for base layout, pages, and portal. - Created a CSS file for styling and a JavaScript file for interactive features like language selection and theme toggling. - Updated documentation source with new configuration and example pages in English and Japanese. - Added a `justfile` target for building the documentation site. * Add language/theme toggle functionality - Created a new Japanese tour index page at docs/ja/tour/index.html - Implemented navigation links for various sections of the cpp-httplib tutorial - Added a language selector to switch between English and Japanese - Introduced theme toggle functionality to switch between light and dark modes - Added mobile sidebar toggle for better navigation on smaller screens

<h1>Getting Started</h1>
|
|
<p>All you need to get started with cpp-httplib is <code>httplib.h</code> and a C++ compiler. Let's download the file and get a Hello World server running.</p>
|
|
<h2>Getting httplib.h</h2>
|
|
<p>You can download it directly from GitHub. Always use the latest version.</p>
|
|
<div class="code-dark"><pre style="background-color:#2d2d2d;">
|
|
<span style="color:#6699cc;">curl</span><span style="color:#f2777a;"> -LO</span><span style="color:#d3d0c8;"> https://github.com/yhirose/cpp-httplib/raw/refs/tags/latest/httplib.h
|
|
</span></pre>
|
|
</div><div class="code-light"><pre style="background-color:#eff1f5;">
|
|
<span style="color:#8fa1b3;">curl</span><span style="color:#bf616a;"> -LO</span><span style="color:#4f5b66;"> https://github.com/yhirose/cpp-httplib/raw/refs/tags/latest/httplib.h
|
|
</span></pre>
|
|
</div>
|
|
<p>Place the downloaded <code>httplib.h</code> in your project directory and you're good to go.</p>
|
|
<h2>Setting Up Your Compiler</h2>
|
|
<table><thead><tr><th>OS</th><th>Development Environment</th><th>Setup</th></tr></thead><tbody>
|
|
<tr><td>macOS</td><td>Apple Clang</td><td>Xcode Command Line Tools (<code>xcode-select --install</code>)</td></tr>
|
|
<tr><td>Ubuntu</td><td>clang++ or g++</td><td><code>apt install clang</code> or <code>apt install g++</code></td></tr>
|
|
<tr><td>Windows</td><td>MSVC</td><td>Visual Studio 2022 or later (install with C++ components)</td></tr>
|
|
</tbody></table>
|
|
<h2>Hello World Server</h2>
|
|
<p>Save the following code as <code>server.cpp</code>.</p>

</div>
|
|
<p>In just a few lines, you have a server that responds to HTTP requests.</p>
|
|
<h2>Compiling and Running</h2>
|
|
<p>The sample code in this tutorial is written in C++17 for cleaner, more concise code. cpp-httplib itself can compile with C++11 as well.</p>

</span></pre>

</div>
|
|
<p>Open <code>http://localhost:8080</code> in your browser. If you see "Hello, World!", you're all set.</p>
|
|
<p>You can also verify with <code>curl</code>.</p>
|
|
<div class="code-dark"><pre style="background-color:#2d2d2d;">
|
|
<span style="color:#6699cc;">curl</span><span style="color:#d3d0c8;"> http://localhost:8080/

|
|
</span><span style="color:#a7adba;"># Hello, World!
|
|
</span></pre>
|
|
</div>
|
|
<p>To stop the server, press <code>Ctrl+C</code> in your terminal.</p>
|
|
<h2>Next Steps</h2>
|
|
<p>Now you know the basics of running a server. Next, let's look at the client side. cpp-httplib also comes with HTTP client functionality.</p>
