get-dois

get-dois

A small module that takes a DOM tree and returns all Digital Object Identifiers (DOIs) located in that tree's metadata.

Unfortunately, academic publishers use a wide variety of metadata "standards". This package normalises between Dublin Core, Highwire Press tags, etc., and the different formatting rules used for DOIs.

To use this library outside of a browser context, you can use a library like jsdom.

This project also includes TypeScript type definitions.

Installation

npm install get-dois --save

Usage

import { getDois } from 'get-dois';

const head = document.getElementsByTagName('head').item(0);
const dois = getDois(head);
//=> [ '10.31222/osf.io/796tu' ]

API

getDois(domTree: Document | Element): string[]

Parameter: domTree

Either window.document or an HTML element whose children might include meta tags containing a DOI.

Returns

An array of DOIs. If no DOIs are found, this will return an empty array. Duplicate DOIs will only be listed once. Note that a page might list multiple DOIs.
