<template>
  <pdf src="./path/to/static/relativity.pdf"></pdf>
</template>

<script>
import pdf from 'vue-pdf'

export default {
  components: {
    pdf
  }
}
```

## Demo

[vue-pdf demo on jsfiddle](https://jsfiddle.net/fossfiddler/5k4ptmqg/145/)

_TBD: fix the demo_

## API

### Props

#### :src <sup>String / Object - default: ''<sup>
The url of the given pdf. `src` may also be a `string|TypedArray|DocumentInitParameters|PDFDataRangeTransport` for more details, see [`PDFJS.getDocument()`](https://github.com/mozilla/pdf.js/blob/8ff1fbe7f819513e7d0023df961e3d223b35aefa/src/display/api.js#L117).

#### :page <sup>Number - default: 1<sup>
The page number to display.

#### :rotate <sup>Number - default: 0<sup>
The page rotation in degrees, only multiple of 90 are valid.
EG: 90, 180, 270, 360, ...

### Events

#### @password <sup>(updatePassword, reason)<sup>
  * `updatePassword`: The function to call with the pdf password.
  * `reason`: the reason why this function is called `'NEED_PASSWORD'` or `'INCORRECT_PASSWORD'`

#### @progress <sup>Number<sup>
Document loading progress. Range [0, 1].

#### @loaded
Triggers when the document is loaded.

#### @page-loaded <sup>Number<sup>
Triggers when a page is loaded.

#### @num-pages <sup>Number<sup>
The sum of all pages from the given pdf.

#### @error <sup>Object<sup>
Triggers when an error occurs.

#### @link-clicked <sup>Number<sup>
Triggers when an internal link is clicked


### Public methods

#### print(dpi, pageList) * _experimental_ *
  * `dpi`: the print resolution of the document (try 100).
  * `pageList`: the list (array) of pages to print.

### Public static methods

#### createLoadingTask(src[, options])
  * `src`: see `:src` prop  
  * `options`: an object of options. 
  This function creates a PDFJS loading task that can be used and reused as `:src` property.  
  The loading task is a promise that resolves with the PDFJS pdf document that exposes the `numPages` property (see example below).
  
  **beware:** when the component is destroyed, the object returned by `createLoadingTask()` become invalid. 
  
  Supported options:
  * onPassword: Callback that's called when a password protected PDF is being opened.
  * onProgress: Callback return loading progress.
  * withCredentials: Wheter or not to send cookies in the fetch request.


## Examples

##### Example - current page / page count
```vue
<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
```vue
<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.promise.then(pdf => {

			this.numPages = pdf.numPages;
		});
	}
}

</script>
```


##### Example - print all pages
```vue
<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
```vue
<template>
	<button @click="$refs.myPdfComponent.print(100, [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14])">print</button>
	<pdf ref="myPdfComponent" src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"></pdf>
</template>
```


##### Example - get text content
```vue
<template>
	<div>
		<button
			@click="logContent"
		>
			log content
		</button>
		<pdf
			ref="myPdfComponent"
			src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"
		></pdf>
	</div>
</template>

<script>

import pdf from 'vue-pdf'

export default {
	components: {
		pdf
	},
	methods: {
		logContent() {

			this.$refs.myPdfComponent.pdf.forEachPage(function(page) {

				return page.getTextContent()
				.then(function(content) {

					var text = content.items.map(item => item.str);
					console.log(text);
				})
			});
		}
	}
}

</script>
```


##### Example - complete
```vue
<template>
	<div>
		<input type="checkbox" v-model="show">
		<select v-model="src" style="width: 30em">
			<option v-for="item in pdfList" :value="item" v-text="item"></option>
		</select>
		<input v-model.number="page" type="number" style="width: 5em"> /{{numPages}}
		<button @click="rotate += 90">&#x27F3;</button>
		<button @click="rotate -= 90">&#x27F2;</button>
		<button @click="$refs.pdf.print()">print</button>
		<div style="width: 50%">
			<div v-if="loadedRatio > 0 && loadedRatio < 1" style="background-color: green; color: white; text-align: center" :style="{ width: loadedRatio * 100 + '%' }">{{ Math.floor(loadedRatio * 100) }}%</div>
			<pdf v-if="show" ref="pdf" style="border: 1px solid red" :src="src" :page="page" :rotate="rotate" @password="password" @progress="loadedRatio = $event" @error="error" @num-pages="numPages = $event" @link-clicked="page = $event"></pdf>
