doi-utils
A small utility for validating, normalizing, and extracting DOIs from text strings.
This repository follows the advice of CrossRef for regular expression patterns.
For the 74.9M DOIs we have seen this matches 74.4M of them. If you need to use only one pattern then use this one.
The utility also recognizes URLs that are likely DOIs, and has specific handling for some repositories (e.g. eLife, Zenodo).
Install
npm install doi-utils
Overview & Usage
import doi from 'doi-utils';
const isValid = doi.validate('http://doi.org/10.1016/j.cageo.2015.09.015');
doi.buildUrl('http://dx.doi.org/10.1016/j.cageo.2015.09.015');
doi.buildUrl('http://www.doi.org/10.1016/j.cageo.2015.09.015');
doi.buildUrl('http://doi.org/10.1016/j.cageo.2015.09.015');
doi.buildUrl('doi:10.1016/j.cageo.2015.09.015');
