Introduction

DivideConfig is smart loader for your application configuration. DivideConfig is load by mode configuration. Mode is to separate for distribution that are development, stage, production. See below configuration architecture.

Configuration Tree Architecture

config/
  config.json
  development.config.json
  stage.config.json
  production.config.json
  |
  +- database/
    |
    +- development.database.config.json
    +- stage.database.config.json

  +- oAuth2/
    |
    +- development.oauth2.config.json
    +- stage.oauth2.config.json
    +- production.oauth2.config.json

config.json

{
  "mode": "development",
  "default: "development"
}

Load complete after Json architecture

{
  "database": {
    ... your configuration
  },
  "oAuth2": {
    ... your configuration
  }
}

DivideConfig is loading all configuration file in config directory, that is starts with mode prefix and xxxx.config.json file. If you set development mode, load all files that is start with "development". For example, "development.database.config.json" and "development.oauth2.config.json".

All loading task is to execute synchronous. So you try to load configuration before your application execute.

Why DivideConfig?

Separate configuration, production and development, stage
Before load to execute strip-json-comments, so your write comment in configuration. It so convenient.
You can set default configuration. If you set development, first loading development configuration and overwrite configuration in preloaded configuration.
Support hjson, yaml, HOCON
- HOCON configuration is make share configuration file with Java, Scala project
- JSON: .json
- YAML: .yaml, .yml
- HJSON: .hjson
- HOCON: .conf, .hocon

Example

See configuration example,

config/development_default_comon
config/production_default_development
config/production_default_development_hjson
config/production_default_development_yaml
config/production_default_development_hocon

var path = require('path');
var loader = require('../lib/Loader');
var configuration = loader.loading(path.join(__dirname, '../config/production_default_development'), 'config.json');

console.log(configuration);

Warning

Javascript hoconfig-js library cannot parse specific comment(start with //). So you can use only start with # comment. Remind, you use only start with # comment.
