IncludeOS web application

Codename: Acorn


Written in C++ and running on the IncludeOS unikernel, Acorn is a highly efficient web application with direct access to the library operating system's facilities

C++ web application framework

Set up a working web application with just a few lines of code.

C++ web application framework inspired by Node.js and Express.js. 

  // Serve index.html on GET /
  router.on_get("/",
  [disk] (auto, auto res)
  {
    disk->fs().cstat("/index.html",
    [res] (auto err, const auto& entry)
    {
      if(err)
        res->send_code(http::Not_Found);
      else
        res->send_file({disk, entry});
    });
  });
Easily serve a static front page with a few lines of code.

Middlewares

Make use of and create simple middlewares to power up the web application. 

    #include <butler>
    #include <director>

    // Serve files from "public/" directory on file requests
    Middleware_ptr butler = std::make_shared<Butler>(disk, "/public");
    server.use(butler);

    // Display simple directory view of directory "public/static"
    Middleware_ptr director = std::make_shared<Director>(disk, "/public/static");
    server.use("/static", director);
Serve and display files by utilizing middlewares.

Built with IncludeOS

IncludeOS is the leanest, purest form of unikernel. Written from scratch in C++, we leverage all the advantages of writing a single-service operating system; we use 100% asynchronicity and simplicity all the way from device drivers, through the whole network stack and up to and including our new framework for building Node.js-style REST APIs in blazingly fast, modern C++14.
