Handling config passed via CLI

[tusharmath]

Consider a use case where —

default.json

{
  "watch": false,
  "port": 9000
}

Command line

node server.js --port=3000

node-config-ts will automatically override the port value of 9000 with 3000. This is a great feature to have but sometimes it can cause conflicts when the command line argument isn't actually intended to override the config.

For example while running tests for the same server.js as follows —

mocha test/server.test.js --watch

The watch passed is intended to be used by mocha and not by server.js. But in this case
the config object will automatically contain watch property which will be set to true. This can change the behaviour of the program drastically.

Also, specifically boolean and number values are not converted and their typeof shows them as strings while the TypeScript definition is boolean or number.
