How to fill a word template using js?

Question

JavaScript

There is a ready-made Word template, how can I fill it out on the site using a form into which data is entered created in js? After filling out the form, the completed template is downloaded from the server.

What library is required to perform these tasks? If she's needed.

Answer 1

Read the off.doc of the small software . And so, here is a lib on npm

Answer 2

In the docx template, mark fields for insertion {field1} {field2}, etc. close
In your
docx program, open it as a regular archive, extract the word/document.xml file from it.
Edit with a replacement as plain text. (First, using regular expressions, extra '<.*?>')
For example, I tried directly in JSzip

function isprXML(xmlfile) {
            // //почистить шаблон до правильного вида переменных {field1}
            var re = /({.*?})/sg;
            var re2 = /(<.*?>)/g;;
            let result = xmlfile.match(re) || [];
            let newres = [];
            result.forEach(element => {
                var newel = element.replace(re2, "");
                xmlfile = xmlfile.replace(element, newel);
            });
            return xmlfile;
        }

Then just replace the {field1} fields with your data
xmlfile = xmlfile.replace("field1", data);
word/document.xml - Put back in the archive
Here is an example in JS - works directly in the browser
