A Boost Based C++ HTTP JSON Server.

Quick Start

To build the dependencies & the project, refer to BUILD-Windows.md or BUILD-ubuntu.md.

• WebApp/bserv contains the source code for bserv.

Hello, World!

This example shows how to use bserv to echo a json object {"msg": "hello, world!"} when requesting localhost:8080/hello.

main.cpp:

#include <bserv/common.hpp>
#include <boost/json.hpp>
boost::json::object hello()
{
        return {{"msg", "hello, world!"}};
}
int main()
{
        bserv::server_config config;
        // config.set_port(8080);
        bserv::server{config, {
                bserv::make_path("/hello", &hello)
        }};
}

CMakeLists.txt:

cmake_minimum_required(VERSION 3.10)

project(hello)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

add_subdirectory(path/to/WebApp/bserv bserv)
add_executable(main main.cpp)
target_link_libraries(main PUBLIC bserv)

Sample Project: WebApp

• WebApp/WebApp is a sample project.
• config-Windows.json and config-ubuntu.json are two sample config file for WebApp's startup parameters. It should be configured and renamed to config.json before you start WebApp.
• To use WebApp, you should setup the database as well.

Database

You can import the sample database:

• Create the database in psql:

  create database bserv;
  

• Create the table in the shell using a sample script:

  psql bserv < db.sql
