urn-parser - Module for URN parsing

Overview

URN-Parser is a module that provides functions for parsing URN (Uniform Resource Name) that is loosly based upon the standard url module within node. Parsing is derived from the excellent parseUri function by Steven Levithan, but stripped down for the urn scheme.

Although the URN-parser is a good start, for a more complete and fully compliant implemnentation I recommend you take a look at the URI Type for javascript module which allows the urn to be inspected as an uri.

What's an URN?

The best place to start if you want to know more about URNs is (of course) the wikipedia article on Uniform Resource Name.

Installation

npm install urn-parser

Using the Module

The 'urn-parser' module is accessed in the standard way by calling require("urn-parser"); and once loaded you have access to the following objects and functions.

Class urn-parser.Parser

The Parser class is a wrapper object class that provides access to an object that can be used to parse urn instances.

This class has the following interface:

Constructor Parser(options)

Creates a new instance with the specified options

Method Parser.parse(urnStr, strictMode)

Parses an URN into components (optionally in strict mode)

Method Parser.complete(obj)

Creates a complete URN definition from its components

Method Parser.format(obj)

Formats an URN definition into a well-formed URN string

Function urn-parser.parse

The parse function is a proxy to the Parser.parse(urnStr, strictMode) method on a singleton Parser instance that is created for the module.

Function urn-parser.complete

The complete function is a proxy to the Parser.complete(obj) method on a singleton Parser instance that is created for the module.

Function urn-parser.format

The format function is a proxy to the Parser.format(obj) method on a singleton Parser instance that is created for the module.
