An elegant C++ REST framework.

Getting Started

Pistache is a web framework written in Modern C++ that focuses on performance and provides an elegant and asynchronous API.

#include "pistache/pistache.h"


git is needed to retrieve the sources. Compiling the sources will require CMake to generate Makefile and a recent version of g++ (at least 4.7).

Also, Pistache does not support Windows yet.

Installing Pistache

To download the latest available release, clone the repository over github.

git clone https://github.com/oktal/pistache.git

Then, init the submodules:

git submodule update --init

Now, compile the sources:

cd pistache
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..
sudo make install

Optionally, you can also run the tests:

make test

Be patient, async_test can take some time before completing.

And that’s it, now you can start playing with your newly installed Pistache framework.

Serving requests


First, let’s start by including the right header

#include "pistache/endpoint.h"

Hello World

Requests received by Pistache are handled with an Http::Handler.

Let’s start by defining a simple HelloHandler:

using namespace Net;

class HelloHandler : public Http::Handler {


    void onRequest(const Http::Request& request, Http::ResponseWriter response) {
         response.send(Http::Code::Ok, "Hello, World");

Handlers must inherit the Http::Handler class and at least define the onRequest member function. They must also define a clone() member function. Simple handlers can use the special HTTP_PROTOTYPE macro, passing in the name of the class. The macro will take care of defining the clone() member function for you.

Final touch

After defining the handler, the server can now be started:

int main() {
    Net::Address addr(Net::Ipv4::any(), Net::Port(9080));

    auto opts = Http::Endpoint::options().threads(1);
    Http::Endpoint server(addr);

For simplicity, you can also use the special listenAndServe function that will automatically create an endpoint and instantiate your handler:

int main() {

Note that by default, listenAndServe will only use 1 thread. You can tweak that by passing an Options argument to the function:

    Http::listenAndServe<HelloHandler>("*:9080", opts);

And that’s it, now you can fire up your favorite curl request and observe the final result:

curl http://localhost:9080/
Hello, World
