Configuration file parser for JSON format.

go-config makes it simple to work with cascading configuration files. It allows you to use cascading configuration files (e.g. one configuration for every environment). You can define options for every environment in different configuration files and load them accordingly to the set environment.

Dokumentation: http://godoc.org/github.com/hypebeast/go-config/config

Build Status:

Test Coverage:

Place your configuration files in a directory (e.g. config). Configuration files need to be valid JSON files, terminated by .json.

The following example loads and parses options from base.json in the config directory:

package main

import (
    "fmt"
    "github.com/hypebeast/go-config/config"
)

type BaseConfig struct {
    Host    string
    Port    int
}

func main() {
    // Initialize the config system
    config.Init("config", "")

    // Get the base config
    config.Get("base", &baseConfig)
}

Inside the configuration directory you can have configurations for different environments.

Example

You can have your basic options in mongo.json that is loaded when no environment is specified and a mongo.stage.json file that is loaded when the environment variable (the name of the environment variable can be set during initialization) is set to stage.

Configuration options in mongo.json will be merged with the options from mongo.stage.json.

The follwoing examples shows the content mongo.js:

{
    "Host": "localhost",
    "Port": 27017
}

And you have a mongo.stage.json file with the following content:

{
    "Host": "mongo-stage.host.com"
}

The resulting configuration for the stage environment will be:

{
    "Host": "mongo-stage.host.com",
    "Port": 27017
}
