ConfigManager

Check ConfigManagerTests

Usage

• Get the path for your Default configuration file. let configPath = NSBundle(forClass: ConfigManagerTests.self).pathForResource("ConfigFile", ofType: "json", inDirectory: "")

• Create the config manager with that path. let configManager = ConfigManager(configPath: configPath)

• ConfigManager will now try to load 2 files in order:

  1. <bundle path>/.ConfigFile.json
  2. <bundle path>/ConfigFile.json

It's recommended that you add .ConfigFile.json to your .gitignore so it acts as a local override.

With Environment per scheme/target

• Define environment variable CONFIG_MANAGER_ENV per scheme or target. Say you have one that's called Dev, one that's Staging and one that's Prod.
• If you initialize the ConfigManager the same way as before, it will now try to load 3 files in order:
  1. <bundle path>/.ConfigFile.json
  2. <bundle path>/ConfigFile.{Dev, Staging, Prod}.json
  3. <bundle path>/ConfigFile.json
• Note that you can override the environment at initialization:
  • let configManager = ConfigManager(configPath: configPath, environment: "Custom")

Extend

• A special key will be read in each configuration file, "!extends" can be put into the json and it will try to load & extend that file:

InheritanceTestParent.json

{
  "parentKey": "parentValue",
  "mergedKey": "mergedParentValue",
  "config": {
    "configKey": {
      "configA": "configAValue",
      "configB": [ "configBValue0", "configBValue1" ]
    }
  }
}

InheritanceTestChild.json

{
  "!extends": "InheritanceTestParent.json",
  "childKey": "childValue",
  "mergedKey": "mergedChildValue",
  "config": {
    "configKey": {
      "childConfigA": "configAChildValue",
      "configB": [ "childConfigBValue0", "childConfigBValue1", "childConfigBValue2" ]
    }
  }
}
