OpenWebProject DN

Working with Distinguished Name(DN) strings in JavaScript

Installation

npm install owp.dn --save

Usage

import DN from "owp.dn";

const dn = new DN("cn=Andreas Arvidsson,ou=Karlstad,o=Repill Linpro,c=Sweden");

DN Class

Represents the entire DN string.

Members

• value: String containing the entire DN.
• rdns: Array containing instances of RDN in reverse order from the DN string.

const dn = new DN("cn=Andreas,o=Repill Linpro,c=Sweden");
dn.value -> "cn=Andreas,o=Repill Linpro,c=Sweden"
dn.rdns -> [ RDN("c=Sweden"), RDN("o=Repill Linpro"), RDN("cn=Andreas") ]  

RDN Class

Represents a single Relative DN.

Members

• attribute: String containing the entire DN.
• value: String containing the value in raw/unescaped format.
• valueEscaped: String containing the value in escaped format.

import { RDN } from "owp.dn";
const rdn = new RDN("cn", "Arvidsson, Andreas");
rdn.attribute -> "cn"
rdn.value -> "Arvidsson, Andreas"
rdn.valueEscaped -> "Arvidsson\, Andreas"

length

const dn = new DN("cn=Andreas,o=Repill Linpro,c=Sweden");
dn.length() -> 3

equals

const dn = new DN("cn=Andreas");
dn.equals(new DN("cn=Andreas")) -> true
dn.equals("cn=Andreas") -> true

getRDN

const dn = new DN("cn=Andreas,o=Repill Linpro");
dn.getRDN(1) -> RDN("cn=Andreas")

getLastRDN

const dn = new DN("cn=Andreas,o=Repill Linpro");
dn.getLastRDN() -> RDN("cn=Andreas")

getFirstRDN

Find first RDN with the given attribute

const dn = new DN("cn=Andreas,o=Repill Linpro");
dn.getFirstRDN("cn") -> RDN("cn=Andreas")

getFirstIndex

Find index of first RDN with the given attribute

const dn = new DN("cn=Andreas,o=Repill Linpro");
dn.getFirstIndex("cn") -> 1

getParent

const dn = new DN("cn=Andreas,o=Repill Linpro");
dn.getParent() -> DN("o=Repill Linpro")

getParents

const dn = new DN("cn=Andreas,o=Repill Linpro,c=Sweden");
dn.getParents() -> [ DN("o=Repill Linpro,c=Sweden"), DN("c=Sweden") ]

append

const dn = new DN("o=Repill Linpro,c=Sweden");
dn.append("cn", "Andreas") -> DN("cn=Andreas,o=Repill Linpro,c=Sweden")

toString

const dn = new DN("cn=Andreas,o=Repill Linpro");
dn.toString() -> "cn=Andreas,o=Repill Linpro"

compareTo

• Used to sort a list of DNs by RDN.value
• Returns -1, 0, +1

const dns = [
    new DN("cn=Andreas,c=Sweden"),
    new DN("cn=Andreas,o=Repill Linpro"),
    new DN("cn=Arvidsson,o=Repill Linpro")
];
dns.sort((a, b) => a.compareTo(b));
dns -> [
    DN("cn=Andreas,o=Repill Linpro"),
    DN("cn=Arvidsson,o=Repill Linpro"),
    DN("cn=Andreas,c=Sweden")
]
