rest-confidence

This is a simple yet powerful configuration server. Tired of configuring many components in many different environments? Rest-confidence centralizes your settings and exposes them as a REST service.

Other use cases include using it as a service directory or as a foundation for A/B testing (read more). It uses confidence, with all it niceties now remotelly accesible through a simple REST service.

Configuration example

{
    "key1": "value",
    "key2": {
        "$filter": "env",
        "production": {
            "limit": 200
        },
        "$default": {
            "limit": 10
        }
    },
    "$meta": {
        "anykey": "anyvalue" // comments are also fine
    }
}

GET /

{
    "key1": "value",
    "key2": {
        "limit": 10
    }
}

GET /key2

{
    "limit": 10
}

GET /key2?env=production

{
    "limit": 200
}

GET /__raw

Gets the raw configuration file contents.

Install & run the server

npm install -g rest-confidence
rest-confidence <path-to-your-config-json>

It runs on port 8000 by default. You can override it defining a PORT environment variable (e.g. PORT=8000 rest-confidence).
