node-cmd-switch

node-cmd-input

Process command line input switches for a node script

How to Install

This is meant to be a library utilized in your project. So, run this from your project folder's root.

npm install node-cmd-input

How to Setup

Require the library at the top of your main script.

var cmdl = require("node-cmd-switch");

How to Use

This will recognize two different kind of commandline switches. You will need to specify what you have. Create the object like this.

//name, description, tag, hasValue
cmdl.addToList("server","Name of  the server to use","-s",true);

Now, the script will check for this on the commandline.

node.exe scriptName.js -s ServerName

Or, maybe you just want to use a simple switch like this.

//name, description, tag, hasValue
cmdl.addToList("recursive","Run the process recursively","-r",false);

And now, the script will check for this.

node.exe scriptName.js -r

Full sample script

Note that the result object is the object returned from the callback. The names are appended to the result object with all the values available. From there, if you added a -s with a serverName, you will be able to use result.serverName to get all the values. This includes the original object as {"name":name, "description": description, "tag": tag, "hasValue": hasValue} and the appended properties of isPresent and valueFound.

So, you can use an if statement to see if a property is there on isPresent and if the property has a value, you will find it in the valueFound property. The original object properties are included for reference.

var cmdl = require("node-cmd-switch");

console.log(cmdl);
cmdl.addToList("server","Name of  the server to use","-s",true);
cmdl.addToList("recursive","Run the process recursively","-r",false);

cmdl.process(function(result){
	console.log(result.server.valueFound);
});
