Configuration

Configuration Files
The DocPad configuration file sits within the root of your DocPad project and is named as one of the following. Each name provides a special meaning. Here are the valid names:
docpad.js a Node JavaScript file, will generally look like: module.exports = {/*the configuration*/}
docpad.json a JSON file, does not allow functions, will generally look like: {/*the configuration*/}
docpad.coffee a Node CoffeeScript file, will generally look like: module.exports = /*the configuration*/
docpad.cson a cson file, will generally look like: /*the configuration*/
The advantage of docpad.js and docpad.coffee over docpad.json and docpad.cson is that they allow us to declare functions, as well as call functions. However, for instances where we cannot trust the contents of the configuration files you would want to use the docpad.json or docpad.cson as they can't do anything naughty.
The advantage of docpad.coffee and docpad.cson over docpad.js and docpad.json is that they allow us to use the CoffeeScript syntax which is a lot more lenient.
Generally, you'll usually find either a docpad.coffee file or a docpad.cson file.
Available Configuration
The following code is of a docpad.coffee file that contains every single configurable DocPad options - in reality you should only include the options that you have actually customised - using the following example for reference only.
docpad.coffee

​
    # =================================
    # Environment Configuration
​
    # Locale Code
    # The code we shall use for our locale (e.g., `en`, `fr`, etc.)
    # If not set, we will attempt to detect the system's locale, if the locale can't be detected or if our locale file is not found for it, we will revert to `en`
    localeCode: null  # default
​
    # Environment
    # Which environment we should load up
    # If not set, we will default the `NODE_ENV` environment variable, if that isn't set, we will default to `development`
    env: null  # default
​
    # Environments
    # Allows us to set custom configuration for specific environments
    environments:  # default
        development:  # default
            # Always refresh from server
            maxAge: false  # default
​
            # Only do these if we are running standalone via the `docpad` executable
            checkVersion: process.argv.length >= 2 and /docpad$/.test(process.argv[1])  # default
            welcome: process.argv.length >= 2 and /docpad$/.test(process.argv[1])  # default

​
            # Listen to port 9005 on the development environment
            port: 9005  # example
}
​
# Export the DocPad Configuration
module.exports = docpadConfig
Environment Configuration File
We also support .env environment configuration file, the format works like so:
.env
KEY=VALUE
KEY2=VALUE2
All key-value pairs are added to the process.env environment variable.
This is useful for setting sensitive information, like API keys, database information, and so on.
If you're using .env using for this purpose, be sure to add .env to your .gitignore file!
Global Configuration File
DocPad will also create a global configuration file located at ~/.docpad.cson (or ~/Dropbox/.docpad.cson if you have Dropbox installed). The ~indicates your home directory (e.g., /Users/balupton), not your project directory.
This file is typically used to store information relating to your DocPad preferences, such as whether or not you have agreed to the TOS and subscribed to our newsletter or not, however it can also be used to load in configuration that you would like applied to all of your projects. Normally, we wouldn't touch this file, however it is useful to on the odd occasion.
For instance, if we wanted to set the default DocPad port to always be 9779 instead of 9778, we can update the global configuration file to include:
docpad.coffee
{
    port: 9779
}
