Build Status

The goal of the E-additives project is to implement a web platform that will provide detailed information about food additives.

This project is a RESTful web service implementation that provides CRUD access to the data which may later be consumed by web or mobile apps using a defined HTTP API.

Check the documentation.


Required software components:

  • Nginx 1.4.x
  • PHP 5.3.x
  • PostgreSQL 9.x
  • Redis 2.2.x

Getting Started

Note that the following steps are to be executed on Linux systems. On Windows you would need to use different commands.

Install required PHP extensions and enable them in php.ini:

  • mcrypt.so
  • openssl.so
  • phar.so
  • php_pdo_pgsql.so
  • php_mbstring.so

Install composer:

curl -s https://getcomposer.org/installer | php

Install dependencies via composer:

php composer.phar install

Create database structure and Import data:

$ cd data
$ psql your-database < `pg_db_schema.sql`
$ psql your-database < `pg_db_app_data.sql`

Please have a look at the pg_db_schema.sql and adjust the user rights and owner of the postgres database.


Configure Nginx

Configuring Nginx can be tricky mainly because of how the Slim framework resolves the request uri. The following configuration assumes a php5-fpm type of setup.

    server {
            listen 80;
            listen [::]:80;

            server_name <your-domain>;
            index index.html index.php;
            root /<path-to-e-additives.web>;

            # remove trailing slashes
            rewrite ^/(.*)/$ /$1 permanent;

            # rewrite api request uri
            rewrite ^/api(.*)$ /index.php last;

            location ~ ^.+\.php {
                    include fastcgi_params;

                    fastcgi_pass unix:/var/run/php5-fpm.sock;
                    fastcgi_index index.php;

                    fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
                    fastcgi_param SCRIPT_FILENAME /<path-to-e-additives.server>$fastcgi_script_name;
                    fastcgi_param SCRIPT_NAME /api$fastcgi_script_name;

                    # send headers only if there are no errors
                    add_header Access-Control-Allow-Origin "<your-domain>";
                    add_header Access-Control-Allow-Methods "GET";
                    add_header Access-Control-Allow-Headers "Content-Type, X-Requested-With, X-Authorization";

            location ~ /\.ht {
                    deny  all;

Configure Application

Copy the config-empty.php to config.php and open the file in a text editor.

  • Configure DB_SETTINGS by specifying database name and user with access privileges.
  • Configure CACHE_SETTINGS if you have a Redis server running.
  • Generate and set client API key in X_AUTH_KEY.
  • Configure BASE_URL by specifying the full path to the API. Just add what you specified in RewriteBase to the http://%s/ string, .e.g, http://%s/ead.server.api.
  • Set MAINTENANCE_MODE to false to enable API calls.


Test using CURL or some REST client tool.

Read the API docs to check what API calls are available and how to use them.
