How do you import Javascript file from node_modules into react using Vite?

Question

How do you load a static asset from node_modules in my case pdf.js (from the build folder of node_modules) so I don't have to set the version every time I update it.

I am migrating from Webpack to Vite, so this is how I use it in my webpack project currently.

<Worker workerUrl="/pdf.worker.bundle.js">

Webpack configuration

'pdf.worker': path.join(__dirname, '../node_modules/pdfjs-dist/build/pdf.worker.js'),

Looking for the Vite equivalent

My Vite configuration file is no different from the stock one.

Things I tried:

• I looked at doing a service worker, but that seems more complex than what I'm looking for.

Answer 1

If you need a URL rather than a worker, my solution was just to import the javascript file from node modules. Vite will handle this

import WorkerPdfJsUrl from 'pdfjs-dist/build/pdf.worker?url'

<Worker workerUrl={WorkerPdfJsUrl} >
  <div
    style={{
      height: '750px',
      width: '900px',
      marginLeft: 'auto',
      marginRight: 'auto',
    }}
  >
    <Viewer
      theme='light'
      fileUrl={pdfFile}
      plugins={[defaultLayoutPluginInstance]}
    />
  </div>
</Worker>
