pdf2doi

This is a node.js tool to find the DOI of pdf scientific articles. It tries to first find it in the document, and also search for information with the CrossRef api.

Install:

npm i pdf2doi

Usage:

const pdf2doi = require("pdf2doi.js");
const doi2bib = require('doi2bib');
 
pdf2doi.fromFile("./497514.pdf").then((doi)=>{
  console.log(doi);
  if(doi.doi) doi2bib.getCitation(doi.doi).then(console.log);
})

It returns an obj with the most trusted DOI information, between the alternatives found in the file, and by the CrossRef search.

{
  doi: '10.1155/2014/497514',
  inFileDOI: '10.1155/2014/497514',
  crossRefDOI: '10.1155/2014/497514'
}

The doi2bib package can be used to return the full information of the founded DOI.
