So you've created a React component but would love to give end users the ability to print out the contents of that component. This package aims to solve that by popping up a new print window with CSS styles copied over as well.
npm install --save react-to-print
import React from 'react';
import ReactToPrint from 'react-to-print';
class ComponentToPrint extends React.Component {
render() {
return (
<table>
<thead>
<th>column 1</th>
<th>column 2</th>
<th>column 3</th>
</thead>
<tbody>
<tr>
<td>data 1</td>
<td>data 2</td>
<td>data 3</td>
</tr>
<tr>
<td>data 1</td>
<td>data 2</td>
<td>data 3</td>
</tr>
<tr>
<td>data 1</td>
<td>data 2</td>
<td>data 3</td>
</tr>
</tbody>
</table>
);
}
}
class Example extends React.Component {
render() {
return (
<div>
<ReactToPrint
trigger={() => <a href="#">Print this out!</a>}
content={() => this.componentRef}
/>
<ComponentToPrint ref={el => (this.componentRef = el)} />
</div>
);
}
}
Calling from functional components with hooks
import React, { useRef } from 'react';
import ReactToPrint from 'react-to-print';
class ComponentToPrint extends React.Component {
render() {
return (
<table>
<thead>
<th>column 1</th>
<th>column 2</th>
<th>column 3</th>
</thead>
<tbody>
<tr>
<td>data 1</td>
<td>data 2</td>
<td>data 3</td>
</tr>
<tr>
<td>data 1</td>
<td>data 2</td>
<td>data 3</td>
</tr>
<tr>
<td>data 1</td>
<td>data 2</td>
<td>data 3</td>
</tr>
</tbody>
</table>
);
}
}
const Example = () => {
const componentRef = useRef();
return (
<div>
<ReactToPrint
trigger={() => <button>Print this out!</button>}
content={() => componentRef.current}
/>
<ComponentToPrint ref={componentRef} />
</div>
);
};
NOTE: Node ^8.6 is required to build the library locally. We use Node ^10 for our CLI checks.
The component accepts the following props (note: ?
denotes an optional prop):
Name | Type | Description |
---|---|---|
trigger |
function |
A function that returns a React Component or HTML element |
content |
function |
A function that returns a component reference value. The content of this reference value is then used for print |
copyStyles |
boolean? |
Copy all <style> and <link type="stylesheet" /> tags from <head> inside the parent window into the print window. (default: true ) |
onBeforeGetContent |
function? |
Callback function that triggers before the library gathers the page's content. Either returns void or a Promise. This can be used to change the content on the page before printing. |
onBeforePrint |
function? |
Callback function that triggers before print. Either returns void or a Promise. Note: this function is run immediately prior to printing, but after the page's content has been gathered. To modify content before printing, use onBeforeGetContent instead. |
onAfterPrint |
function? |
Callback function that triggers after print |
onPrintError |
function(errorLocation: string, error: Error)? |
Callback function that will be called if there is a printing error serious enough that printing cannot continue. Currently limited to Promise rejections in onBeforeGetContent or onBeforePrint . Use this to attempt to print again. errorLocation will tell you in which callback the Promise was rejected. |
removeAfterPrint |
boolean? |
Remove the print iframe after action. Defaults to false . |
pageStyle |
string? |
Override default print window styling |
bodyClass |
string? |
Class to pass to the print window body |
Why does react-to-print
skip <link rel="stylesheet" href="">
tags?
<link>
s with empty href
attributes are INVALID HTML. In addition, they can cause all sorts of undesirable behavior. For example, many browsers - including modern ones, when presented with <link href="">
will attempt to load the current page. Some even attempt to load the current page's parent directory.
