I am searching for a JavaScript library, which can read .doc - and .docx - files. The focus is only on the text content. I am not interested in pic
You can use docxtemplater for this (even if normally, it is used for templating, it can also just get the text of the document) :
var zip = new JSZip(content);
var doc=new Docxtemplater().loadZip(zip)
var text= doc.getFullText();
console.log(text);
See the Doc for installation information (I'm the maintainer of this project)
However, it only handles docx, not doc
