vue-pdfjs-demo

This project demonstrates how a simple PDF viewer could be implemented using Vue and PDF.js. This is not a fully-featured PDF document viewer with sophisticated controls, but could serve as the basis for one.

To learn more, checkout the series of posts describing how this project was implemented.

• Basic page rendering
• Fetching and rendering lazily
• Extracting a data component
• Refactoring to nested abstract components

Setup

To run the project locally:

$ git clone https://github.com/rossta/vue-pdfjs-demo
$ cd vue-pdfjs-demo
$ yarn install
$ yarn serve

Installation

To use the project inside your Vue app :

• Create a .env file at the root directory of your project
• this .env file should contain this : VUE_APP_PDF_URL=https://cors-anywhere.herokuapp.com/YOURURL (cors-anywhere permits to avoid cors failure)
• npm install

Then, copy this code where you want inside you project :

<template>
      <PDFViewer
        class="grey"
        v-bind="{url}"
        @document-errored="onDocumentErrored"
      >
        <PDFUploader
          v-if="enableUploader"
          slot="header"
          :document-error="documentError"
          class="header-item"
          @updated="urlUpdated"
        />
      </PDFViewer>
</template>

<script>
import PDFUploader from 'vue-pdfjs-demo/src/components/PDFUploader.vue'
import PDFViewer from 'vue-pdfjs-demo/src/components/PDFViewer.vue'

export default {
  components: {
    PDFUploader,
    PDFViewer,
  },
  data() {
    return {
      url: process.env.VUE_APP_PDF_URL,
      documentError: undefined,
      enableUploader: process.env.VUE_APP_UPLOAD_ENABLED === 'true',
    };
  },
  methods: {
    urlUpdated(url) {
      this.documentError = undefined;
      this.url = url;
    },
    onDocumentErrored(e) {
      this.documentError = e.text;
    },
  },
}
</script>
