Comparison of three format files. Properties. conf. json

The three file formats each has advantages.

• Java .properties :
  • Java Standard, built in to JVM
  • Supported by many tools such as IDEs
• Json:
  • Easy to generate programmatically
  • Well-defined and standard
  • Human maintenance, with no-to-write comments, and no mechanisms to avoid duplication of similar config section S
• hocon/ .conf :
  • Nice for humans to read, type, and maintain, with more lenient syntax
  • Built-in tools to avoid cut-and-paste
  • Ways to refer to the system environment, such as system properties and environment variables

The idea would is the use of JSON if you ' re writing a script to spit out config, and use Hocon if you ' re maintaining config by Hand. If you ' re doing both and then mix the other.
