json-compile v0.1.2

json-compile

Compiles references in given json file into single structure

Overview

Its about simple inheritance of json configs in your applications. It simply finds out all $ref keys inside given file and replaces them with referenced values. First will be replaced outer references (to outer files), second - inner references (in started with # symbol).

Example

Imagine you have base config and his extension.

// inside /dir/base/extension.json
{
    "$ref": "../base.json",
    "host": "127.0.0.1",
    "port": "8080"
}

// inside /dir/base.json
{
    "name": "json-compile"
}

Inside your program you could get compiled config with json-compile module:

// inside your program
var compile = require("json-compile"),
    path    = require("path");

compile(path.resolve(__dirname, "./dir/base/extension.json"), function(err, config) {
    console.log(typeof config); // object
    console.log(config); // { "host": "127.0.0.1", "port": "8080", "name": "json-compile" }
});
