This repository contains a simple web news server. The project was created as a test task of the Metalamp company.

To run and install the program, you must install the stack. After installing stack, clone this repository. Install the compiler (if required) and build the project.

# install compiler
  stack setup
# build project
  stack build

token {
        lifetime = 86400 
      }
database {
    host = "localhost"
    port = "5432"
    login = "login"
    password = "password"
    name = "ServerNews"
         }
logger {
    priority = "Debug"/"Info"/"Warning"/"Error"
       }
server {
    port = 8000
    maximum_body_flush = 1
       }
pool {
    num_stripes = 1
    idle_time = 40
    max_resources = 10
     }

Before the run, you must create database and run postgresql server.

For Linux:

sudo service postgresql start - for starting postgresql server;
sudo su - postgres - for changing user;
createdb -D pg_default -E UTF8 -l en_US.UTF-8 -T template0 -O <login> <data_base_name>  - for creating new database.

For Windows:

createdb -U <login> -D pg_default -E UTF8 -l Russian_Russia.1251 -O <login> <data_base_name>
