This is a nodejs module to allow management of persistent and environment variable configuration.

The module can be added to your project with:

npm install @adobe/aio-lib-core-config --save

Here is a snippet:

const config = require('@adobe/aio-lib-core-config')

// set a key value
config.set('pgb.authtoken', 1234)

// reload data from files and environmental variables
config.reload()

// get all stored data
config.get()

// get data from a given key
config.get('pgb.authtoken')

// delete a key
config.delete('pgb.authtoken')

The user default location is:

1. ENV['AIO_CONFIG_FILE']
2. ENV['XDG_CONFIG_HOME']/aio
3. <HOME>/.config/aio

depending on whether the specified environmental variables exist

Local configuration is loaded from $PWD/.aio

A local .env file is also loaded. This file can contain environmental variables

Resolving configuration is done in two steps:

1. .env file is read, parsed and hoisted to environment variables ( process.env )
2. user and local files are read

Inheritance is similar to NPMRC and can be set using user file, project file and matching environment variables. Values are read and merged in the following order in increasing priority:

1. user config eg. ~/.config/aio
2. project config eg. $PWD/.aio
3. environment variables matching AIO_<PLUGIN>_<KEY>

$ AIO_PGB_AUTHTOKEN=1234 node
> config.get('pgb.authtoken')
1234

$ AIO_PGB_AUTH__TOKEN=1234 node # use double underscores to specify an underscore
> config.get('pgb.auth_token')
1234
