uConfLoad

The Universal Config Loader

==== Code can be not production quality, feedback welcome ====

TL;DR (How to?)

You can check the very basic tests/test.js.

// load module
const uconfload = require('uconfload');

// load -c arg for config file location
const args = uconfload.loadArgs();

// load config file
const config = uconfload.loadConfig(args.config);

// update config with env vars
uconfload.loadEnv(config);

Why?

Simple, I wanted to have something that I find relatively simple, that I can use in container and non-container applications, and that will be the same across different programming languages (check uconfload for python also).

But there is blah!

Yes, I know, but this makes my life easier by (maybe) using blah as an underlying component.

The details

The following functions are available as part of the package:

• loadArgs
• loadConfig
• loadEnv

loadArgs

Parse command line arguments. Only '-c|--config' supported at the moment, to indicate where the config file is located. Returns a Namespace object.

loadConfig

Read and (YAML)parse the config file. Returns a dictionary (associative array; hash; dict; etc.) object.

loadEnv

Parse the passed object and update the keys starting with 'env:<type>:' with the corresponding environment variable. Logs an error if a required environment variable is not present.

Supported <type> conversions are:

• str -> no conversion
• list -> convert a CSV to [] (array) object
• bool -> convert [Nn0]o?|[Ff]alse or [yY1](es)?|[Tt]rue to corresponding boolean object
• int|float -> convert to number object
