good-config

Easy to use centralized config with the goal of having config simple and extendable.

Version 2.0.0 - Breaking changes

• Update dependencies
• remove S3 support

Version 1.1.2

Update dependencies (#5)

Version 1.1.1

Fixed the bug (#2) which ignores empty values to be set bia environmental variables.

Version 1.1.0

Added envify functionality. It means you can now just define your config the way you want (json/yml). In run time, if you needed to overwrite a key, just follow Uppercase+Underscore and you would be able to overwrite it. For example you have a config like this:

{
  key1: "value1",
  key2: {
    subKey: 1,
    anotherKey: "changeme"
  }
}

Say you want to change anotherKey value via environmental variables. You can just set KEY2_ANOTHERKEY to the value you want and good-config will replace it with the correct value.

Main features

• Supports for both yaml and json
• Possibility to add your own provider
• Hierarchical support thanks to merge-config
• Envify support: You can overwrite any config key via env variables and envify convert parent.key to PARENT_KEY

Currently it has these providers:

• FileSystem
• Feel free to make PR for other providers

Installation

npm install good-config

File structure

/myproduct
    default.json
    production/
        default.json
        euw.json
    staging/
        default.json
        euw.json
        use.json

How to use

To get the config before starting the app, just wrap the server startup call in app.js.

const Config = require("good-config");

const config = new Config({
  path: "media-service",
  format: "json", // Optional
});

config
  .load()
  .then(() => {
    app.listen(config.get("port"), function() {
      console.log("Express app listening on port " + config.get("port"));
    });
  })
  .catch(err => {
    console.log("Failed to load the config");
  });

Synchronous loading

There is also the option of loading config from filesystem synchronously, by calling config.loadSync(). See examples folder.

Available options

• path : Path to the config file.
• format: Format of config files - Default json
• provider: Name of the provider class, [FileSystem]
• env: Content of NODE_ENV, [production, development, ...]
