• src: see :src prop
  This function creates a PDFJS loading task that can be used and reused as :src property.

Examples

Example - current page / page count

<template>
  <div>
    {{ currentPage }} / {{ pageCount }}
    <pdf
      src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"
      @num-pages="pageCount = $event"
      @page-loaded="currentPage = $event"
    ></pdf>
  </div>
</template>

<script>
import pdf from 'vue-pdf';

export default {
  components: {
    pdf,
  },
  data() {
    return {
      currentPage: 0,
      pageCount: 0,
    };
  },
};
</script>

Example - display multiple pages of the same pdf document

<template>
  <div>
    <pdf
      v-for="i in numPages"
      :key="i"
      :src="src"
      :page="i"
      style="display: inline-block; width: 25%"
    ></pdf>
  </div>
</template>

<script>
import pdf from 'vue-pdf';

var loadingTask = pdf.createLoadingTask(
  'https://cdn.mozilla.net/pdfjs/tracemonkey.pdf'
);

export default {
  components: {
    pdf,
  },
  data() {
    return {
      src: loadingTask,
      numPages: undefined,
    };
  },
  mounted() {
    this.src.then((pdf) => {
      this.numPages = pdf.numPages;
    });
  },
};
</script>

Example - print all pages

<template>
  <button @click="$refs.myPdfComponent.print()">print</button>
  <pdf
    ref="myPdfComponent"
    src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"
  ></pdf>
</template>

Example - print multiple pages
