Example Usage

webpack.config.ts

import CopyPlugin from "copy-webpack-plugin";

...

const config = {
  ...
  plugins: [
    ...
    new CopyPlugin({
      patterns: [
        {
          from: "PATH/TO/NODE_MODULES/document-viewer/dist/worker/pdf.worker.min.js",
          to: "PATH/TO/WORKER/FILE"
        }
      ]
    }
  ]
}

With HTML and Vanilla JS

Call the init script in the root of your JS application using the path to your worker file.

index.js

import { init } from 'document-viewer'

init("PATH/TO/WORKER/FILE");

Wherever you want to include a document viewer in the HTML, include a <div /> with class="viewer-container" and id being some unique key (on the page) and data-document-url being the url of the document you want to display. Also make sure you're importing styles.css from the package in your HTML head.

index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <script src="./index.js"></script>
    <link rel="stylesheet" href="../node_modules/document-viewer/dist/styles/styles.css"></link>
  </head>
  <body>
    <div class="viewer-container" id="doc-1" data-document-url="https://raw.githubusercontent.com/mozilla/pdf.js/ba2edeae/web/compressed.tracemonkey-pldi-09.pdf"></div>
  </body>
</html>

With React

Import the Viewer component and call it with the proper documentId, documentUrl, and workerSrc props. Also make sure to import styles.css in your app.

index.jsx

import React from 'react'
import { Viewer } from 'document-viewer'
export default () =>
  <Viewer
    documentId="doc-1"
    documentUrl="https://raw.githubusercontent.com/mozilla/pdf.js/ba2edeae/web/compressed.tracemonkey-pldi-09.pdf"
    workerSrc="PATH/TO/WORKER/FILE"
  />
