cascade-config-http

cascade-config loader over http

Quick Start

cascade-config-http adds a loader to cascade-config to allow reading from urls. Only application/json response bodies are supported.

var CC_base = require('cascade-config');
var CC_http = require ('cascade-config-http');
var CC = CC_http (CC_base);

var config = new CC();

config
.obj ({cc: {n: 'ooo'}, x: 0})
.url('mongodb://{env}-config.server.com') 
.done(function (err, cfg) {
  ...
});

API

• .mongodb (url, opts): reads an object as json from an url (which supports variable substitution). opts is optional, and can contain:
  • ignore_missing: if the url returnd a 404, produce an empty object. Otherwise, http 404 esponses are treated as errors
  • mount: mount result inside this path. For example, if an url returns {a: 1, b: 3} and options are {mount: 'a.b.c} the result will be {a: {b: {c: {a: 1, b: 3}}}}

Variable expansion

As it happens with standard loaders in cascade-config read objects from url are then subject to variable expansion using so-far read config; also, config read by this loader ca
