ExpressC++

This is a library similar to ExpressJS framework. It was developed for C++/Qt developers to make it easier to develop web applications.

Usage

Preparations

First of all you have to have installed Qt 5.12.2*

(note that the application was developed under Qt v5.12.2, that's why the reference is to this version. It may work with the newer versions as well)

After that download and build the project. It will require extra sources (general interfaces provided by opensalad organization).

cd ~
git clone https://github.com/opensalad/interfaces
git clone https://github.com/arsdever/expresscpp
cd expresscpp
qmake
make

If case you download components in different folders, please have a look at the .pro file of expresscpp component to make sure that given include path is correct

Example code

This is a simple code that uses the library.

// example.cpp
#include <QCoreApplication>
#include <server.h>

using namespace ad::http;

int main(int argc, char **argv)
{
    QCoreApplication app(argc, argv);

    Server express;
    express.GET(QRegularExpression("/*"), [](Server::request_t &req, Server::response_t &res) {
        res.setBody("Hello World");
    });
    express.begin();

    return app.exec();
}

Example .pro file

TEMPLATE = app
TARGET = application
DEFINES += QT_DEPRECATED_WARNINGS
LIBS += -L../expresscpp -lexpresscpp
INCLUDEPATH += <PATH_TO_INTERFACES_PROJECT> <PATH_TO_EXPRESSCPP_PROJECT>
SOURCES += example.cpp
QT += core

Result

After all preparings, build the application using the following command from example containing directory

qmake
make

and run it (don't miss to update LD_LIBRARY_PATH or simply copy the expresscpp.so.* files into directory)

LD_LIBRARY_PATH=<PATH_TO_EXPRESSCPP> ./application

or

cp <PATH_TO_EXPRESSCPP>/*.so* ./
./application

or add post-build event into expresscpp.pro file to copy built libraries into this path.

Now open any application to make a HTTP GET call. Enter uri localhost:8008/any/path. Do call and you will get respond

Hello World

Contribution

If you would like to contribute, please feel free for any feedback, code contribution, feature offer, code advice and etc. Also feel free to create an issue.

3rd party

As you can guess, the library is based on Qt library. In future it's planned to remove all Qt dependencies.
