Servinator

Reads a config file and starts a server with it.

function servinate(serverGenerator, configArgName, configEnvVar)

This will first attempt to read a configuration, by looking for an argument passed to the node process, specified by configArgName, or an environment variable, specified by configEnvVar, that contains the file name of a JSON file containing the config.

The configuration file that is specified *must* contain a "port" variable, which specifies what port the server should listen on.

For example, if configArgName is set to "wizzlemubs", and the process was started with node server --wizzlemubs ~/scary/mubs.json, the configuration would be read from ~/scary/mubs.json.

configArgName takes precedence over configEnvVar.

• serverGenerator required — a function which takes a single argument - a configuration object - and returns an http server.
• configArgName optional - the name of the process argument which specifies the location of the config json file. defaults to "config".
• configEnvVar optional - the name of the environment variable which specifies the location of the config json file. defaults to "CONFIG_FILE".

Example server.js

require('servinator')(require('./my_amazing_server'), 'amazement');

Which would be run with

node server --amazement ./amazing.json
