react-pdf-js
provides a component for rendering PDF documents using PDF.js. Written for React 15/16 and ES2015 using the Airbnb style guide.
Usage
Install with npm install react-pdf-js
Use in your app (showing some basic pagination as well):
import React from 'react';
import PDF from 'react-pdf-js';
class MyPdfViewer extends React.Component {
state = {};
onDocumentComplete = (pages) => {
this.setState({ page: 1, pages });
}
onPageComplete = (page) => {
this.setState({ page });
}
handlePrevious = () => {
this.setState({ page: this.state.page - 1 });
}
handleNext = () => {
this.setState({ page: this.state.page + 1 });
}
renderPagination = (page, pages) => {
let previousButton = <li className="previous" onClick={this.handlePrevious}><a href="#"><i className="fa fa-arrow-left"></i> Previous</a></li>;
if (page === 1) {
previousButton = <li className="previous disabled"><a href="#"><i className="fa fa-arrow-left"></i> Previous</a></li>;
}
let nextButton = <li className="next" onClick={this.handleNext}><a href="#">Next <i className="fa fa-arrow-right"></i></a></li>;
if (page === pages) {
nextButton = <li className="next disabled"><a href="#">Next <i className="fa fa-arrow-right"></i></a></li>;
}
return (
<nav>
<ul className="pager">
{previousButton}
{nextButton}
</ul>
</nav>
);
}
render() {
let pagination = null;
if (this.state.pages) {
pagination = this.renderPagination(this.state.page, this.state.pages);
}
return (
<div>
<PDF
file="somefile.pdf"
onDocumentComplete={this.onDocumentComplete}
onPageComplete={this.onPageComplete}
page={this.state.page}
/>
{pagination}
</div>
)
}
}
module.exports = MyPdfViewer;
Scaling
The PDF can be scaled in a couple of different ways.
Stretch to fill width/height
Use the prop fillWidth
to make the PDF stretch to the width of the parent element (generally speaking, this will be the enclosing <div>
), or use fillHeight
to do the same for the height of the PDF. The PDF will be scaled proportionately.
Both fillWidth
and fillHeight
default to false
.
Note: fillWidth
has precedence over fillHeight
. So if you use both, the PDF will stretch to fill the width.
Example:
<div className="parentDivWhoseWidthAndHeightAreUsedToStretchThePdf">
<PDF
file="somefile.pdf"
fillWidth
fillHeight // this will be ignored because fillWidth is also passed
/>
</div>
Set scale directly
You can also set the scale manually by passing the scale
prop. A scale
between 0
and 1
shrinks the PDF, and a scale
greater than 1
enlarges it.
scale
defaults to 1
.
Note: the value of scale
will be ignored if you also use fillWidth
or fillHeight
.
Example:
<div>
<PDF
file="somefile.pdf"
scale={1.5}
/>
</div>
