Example

<template>
  <!-- used `style="height: 100vh;"` because without it in the Firefox 89 and Chrome 91 (June 2021) the `vue-pdf-app` is not rendering on the page, just empty space without any errors (since `vue-pdf-app` does not have height and it is the top tag in the generated markup ) -->
  <!-- or you can just wrap `vue-pdf-app` in <div> tag and set height for it via CSS (like in `Script tag (unpkg)` example below) -->
  <vue-pdf-app style="height: 100vh;" pdf="https://file-examples-com.github.io/uploads/2017/10/file-example_PDF_1MB.pdf"></vue-pdf-app>
</template>

<script>
import VuePdfApp from "vue-pdf-app";
// import this to use default icons for buttons
import "vue-pdf-app/dist/icons/main.css";

export default {
  components: {
    VuePdfApp
  }

^new :id-config

Description: If default toolbar UI doesn't suite you it is possible to build custom toolbar. The prop contains elements ID to which to bind functionality. If element ID is specified in this prop appropriate button will be hidden in a default toolbar. May not work with UI framework components. That is because pdfjs internally manages attributes specific to a certain HTML element (for instance pdfjs toggles disabled attribute of a button but it won't if a div is used instead of a button). So it is better to use native HTML element specified as recommended in ID config specification below. Four slots are specially designed to build custom toolbar (are situated near a pdf page): viewer-header, viewer-prepend, viewer-append, viewer-footer (refer slots API). It is also possible to use other slots or elements outside vue-pdf-app.
Type: ID config (see below)
Required: false
Usage:

<template>
  <div>
    <button :id="idConfig.zoomOut" type="button">Zoom out</button>
    <vue-pdf-app :id-config="idConfig">
      <template #viewer-prepend>
        <div class="viewer-prepend">
          <button :id="idConfig.zoomIn" type="button">Zoom in</button>
        </div>
      </template>
    </vue-pdf-app>
  </div>
</template>

<script>
export default {
  data() {
    return {
      idConfig: { zoomIn: "zoomInId", zoomOut: "zoomOutId" }
    };
  }
};
</script>

Icons customization

To use default icons import "vue-pdf-app/dist/icons/main.css";.

To use custom icons you have to implement icons.css:

.vue-pdf-app-icon::before,
.vue-pdf-app-icon::after {
  font-family: "your font family";
}

.vue-pdf-app-icon.zoom-out::before {
  content: "icon code";
}

Light/dark themes

Algorithm of theme apply

Toggle theme button is not implemented by default. It's up to you to decide where to place it. The button can be implemented with slots:

<vue-pdf-app>
  <template #footer="{ toggleTheme }">
    <button @click="toggleTheme" type="button">Toggle theme</button>
  </template>
</vue-pdf-app>

Localized panel

English is the default language for panel. Use <link rel="resource" type="application/l10n" href="path-to-localization-file"> in your html for localization. See localization file examples.

Examples

Script tag (unpkg)

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta charset="utf-8" />
    <title>Vue-pdf-app demo</title>
    <link
      rel="stylesheet"
      href="https://unpkg.com/[email protected]/dist/icons/main.css"
    />
    <script src="https://unpkg.com/vue"></script>
    <script src="https://unpkg.com/[email protected]"></script>
    <style>
      body,
      html {
        padding: 0;
        margin: 0;
      }
    </style>
  </head>

  <body>
    <div id="app" style="height: 100vh;">
      <vue-pdf-app pdf="/sample.pdf"></vue-pdf-app>
    </div>
    <script>
      new Vue({
        components: {
          VuePdfApp: window["vue-pdf-app"]
        }
      }).$mount("#app");
    </script>
  </body>
</html>

Typescript

<template>
  <div id="app">
    <vue-pdf-app pdf="/sample.pdf"></vue-pdf-app>
  </div>
</template>

<script lang="ts">
import "vue-pdf-app/dist/icons/main.css";
import VuePdfApp from "vue-pdf-app";
import { Component, Vue } from "vue-property-decorator";

@Component({
  components: {
    VuePdfApp
  }
})
export default class App extends Vue {}
</script>

Lazy loading

PDFJS is a huge package (see the library size table above). So use lazy loading to split your bundle into small pieces.

<template>
  <div id="app">
    <vue-pdf-app></vue-pdf-app>
  </div>
</template>

<script>
import "vue-pdf-app/dist/icons/main.css";
import Loader from "./components/Loader.vue";

export default {
  name: "App",
  components: {
    "vue-pdf-app": () => ({
      component: new Promise((res) => {
        return setTimeout(
          () => res(import(/* webpackChunkName: "pdf-viewer" */ "vue-pdf-app")),
          4000
        );
      }),
      loading: Loader
    })
  }
};
</script>

PDFJS interaction

You can interact with pdfjs library when pdf is opened via open event.

<template>
  <div id="app">
    <div id="pdf-wrapper">
      <vue-pdf-app pdf="/sample.pdf" @open="openHandler"></vue-pdf-app>
    </div>
    <div id="info">
      <h1>PDF info:</h1>
      <div v-for="item in info" :key="item.name">
        <span>{{ item.name }}: {{ item.value }}</span>
        <br />
      </div>
    </div>
  </div>
</template>

<script>
import "vue-pdf-app/dist/icons/main.css";
import VuePdfApp from "vue-pdf-app";

export default {
  name: "App",
  components: {
    VuePdfApp
  },
  data() {
    return {
      info: []
    };
  },
  methods: {
    async openHandler(pdfApp) {
      this.info = [];
      const info = await pdfApp.pdfDocument
        .getMetadata()
        .catch(console.error.bind(console));

      if (!info) return;
      const props = Object.keys(info.info);
      props.forEach((prop) => {
        const obj = {
          name: prop,
          value: info.info[prop]
        };
        this.info.push(obj);
      });
    }
  }
};
</script>
