Application config
Contents
Applications may be configured via file.
Config folder
Your development environment (aka sandbox), can read application-specific configurations files and provision this to each app. By default, it will scan the folder located in $XP_HOME/config/
| The config folder also contains the standard XP configuration files. |
Config file
Simply adding or updating a file called <appname>.cfg in the config folder will automatically restart your application, and provision the new configuration values.
This is a hot restart, and will typically be very fast. XP itself does not need to be restarted.
| If you’re operating an XP cluster, the configuration file should be copied to every server node - this is because XP by default will run all applications on every node in the cluster. |
Accessing config
Developers can easily access the application’s config via the JavaScript controllers.
Given the following configuration file:
<appname>.cfg
secretkey = 123456789The value can be optained using a single line of code:
Sample JS controller
var myKey = app.config.secretkey;
