minified pdf-lib : no access to field.constructor.name

[somel-web]

When using the minified version of pdf-lib field.constructor.name return a or e.
So it's impossible to differentiate field type.
No problem with the non-minified version.

Not exactly sure what you're trying to do since you didn't share any code snippets. If you're trying to refine the type of a field, please use instanceof checks. For example:

import { PDFTextField } from 'pdf-lib';

const fields = form.getFields();
fields.forEach(field => {
  if (field instanceof PDFTextField) {
    console.log(field.getText());
  }
});

Using javascript browser code

from the api doc
https://pdf-lib.js.org/docs/api/classes/pdfform#getfields

const form = pdfDoc.getForm()
const fields = form.getFields()
fields.forEach(field => {
  const type = field.constructor.name
  const name = field.getName()
  console.log(`${type}: ${name}`)
})

with minified version
<script src="https://unpkg.com/pdf-lib/dist/pdf-lib.min.js"></script>
....
field.constructor.name return 'a' or 'e'

with non-minified version
<script src="https://unpkg.com/pdf-lib/dist/pdf-lib.js"></script>
....
field.constructor.name return the correct type, eg : PDFTextField

indeed

const {PDFDocument,PDFTextField,PDFButton} = PDFLib
....
const fields = form.getFields();
fields.forEach(field => {
  if (field instanceof PDFTextField) {
    console.log(field.getText());
  }
});

is working well in both case.
