constantly

Constantly

Take flat constants files and turn their properties into a read-only object.

Usage

Given a JSON structure like this which defines two ACCOUNT.TYPEs, USER and ADMIN:

[{
    "feature": "ACCOUNT",
    "category": "TYPE",
    "property": "USER",
    "comment": "A regular user that can login and do normal things",
    "value": 100,
    "sequence": 0
},
{
    "feature": "ACCOUNT",
    "category": "TYPE",
    "property": "ADMIN",
    "comment": "User which is an administrator",
    "value": 200,
    "sequence": 0
}]

We can get the value of those constants like so:

var constantly = require('constantly');
var $C = constantly(path.resolve('example.json'));

var admin = $C.ACCOUNT.TYPE.ADMIN.value; //200

JSON Setup

You are required to define a feature, category, and property to “namespace” each constant.

Comments

Comments are useful for authors of the source JSON but are ignored otherwise.

Sequence

Sequence is used for ordering properties in UI.
