Storing settings in a JSON file

CFConfig can represent the settings for any server in a generic JSON format. Even though some settings may be specific to Lucee Server or Adobe ColdFusion, the JSON format itself is generic and can be used on any engine. Any settings that don't apply to a given engine will simply be ignored. For example, caches or mail servers past the first one are ignored when importing to Adobe ColdFusion.

You may choose to commit your settings to a file called .cfconfig.json in the webroot, which will cause them to automatically get loaded in one every server start. This is the easiest way to share configuration with your coworkers. One issue with this may be that you don't want the json file in your web root in case it accidentally gets moved to a production server and it directly accessible. Web servers such as Apache will not serve files starting with . by default, but other web servers will happily share those "hidden" files. You can work around this by placing the JSON file outside the web root and using the cfconfigFile property in your server.json to point to it. You can use relative paths like ../build/mySettings.json.

Another potential issue with the JSON file is that you may have secrets in your config such as passwords that you don't want to commit to your repo or that are simply different on some servers. You can manage this by using CommandBox's "system settings" which will expand any environment variables in your CFConfig JSON file. System settings are in the format ${mySetting} and would look like so in your JSON file:

  "adminPassword" : "${LOCAL_DEV_CF_PASS}"

That JSON above would automatically replace the adminPassword setting with the value of an environment variable called LOCAL_DEV_CF_PASS.

You can take this a step further and provide a default value so the env var is just an override. The format is ${name:default}.

"requestTimeout" : "${LOCAL_DEV_TIMEOUT:0,0,1,0}"

That JSON above would set the request timeout to 1 minute unless it was overridden by an env var called LOCAL_DEV_TIMEOUT.
