Esnure that postgresql-server-dev-9.1, libxml2, libxml2-dev and gyp packages are present on your system.

The app is build at the top of the pleasant Node Package Manager. To download and set up the whole dependancies three, simply run from the project's root directory :

Step 2: Edit the configuration

Use configuration file

The default configuration is present into config/default.json. Every modifications in this file will be commited. The runtime.json file is an auto-generated file that you shouldn't edit.

  • Development mode: If you want to overide default values, you have to create a file named config/development.json and corresponding to your local configuration. This file will be ignored by git.
  • Production mode: if you want to overide default values, you have to edit the config/production.json file to fit with your production environment. This file will be ignored by git.

Alternative: use environment variables

The following environment variables can be use with the highest priority :

  • PORT defines the port to listen to (ex: 80);
  • DATABASE_URL defines the database URL;
  • NODE_ENV defines the runtime mode that affects the configuration (ex: development, production, etc).
