json-config

A command line tool that accepts a simple environment-sensitive JSON template file used to generate a config JSON file, typically used as a part of a greater build system.

##Install

npm install -g @breautek/json-config
npm link @breautek/json-config

##Usage

json-config -e prod

Additional options

• -v Prints version
• -h Prints help
• -e Sets the environment. This is required.
• -c Sets the input config. Defaults to ./config.json
• -o Sets the output config. Defaults to ./local_config.json

In your input config file, any key name that is prefixed with "env:" will be included only if it matches the environment command line argument.

##Sample Input Config Suppose you had an config file that looked something like this:

{
    "name": "Example Name",
    "dev:debug" : true,         // The key "debug" will only get set if the environment is "dev"
    "prod:debug": false,        // The key "debug" will be set to false if the environment is "prod"
    "db": {
        "dev:host": "127.0.0.1",
        "prod:host": "myprodserver"
    }
}

The output config file will look like:

{
    "name": "Example Name",     // This is untouched because it had no environment prefix at all.
    "debug": false,             // This is false, becuase of -e prod
    "db" : {
        "host": "myprodserver"
    }
}

##Common Practices

• Add the local_config.json (or the output json) to your ignore file.
