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.ID config (see below)false<template>

To use default icons import "vue3-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";
}
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>
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.
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 "vue3-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>
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 "vue3-pdf-app/dist/icons/main.css";
import VuePdfApp from "vue3-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>
