React Print is a library that allows you to easily print elements in your React application. With just a few lines of code, you can add print functionality to your application without having to worry about the details of printing.
To install React Print, you can use npm or yarn:
npm install react-print --save
or
yarn add react-print
To use React Print, you need to import the ReactToPrint
component and wrap your component that you want to print with it. Here's an example:
import React from 'react';
import ReactToPrint from 'react-print';
class ComponentToPrint extends React.Component {
render() {
return (
<div>
<h1>Print Me!</h1>
</div>
);
}
}
class PrintComponent extends React.Component {
render() {
return (
<div>
<ReactToPrint
trigger={() => <button>Print</button>}
content={() => this.componentRef}
/>
<ComponentToPrint ref={(el) => (this.componentRef = el)} />
</div>
);
}
}
export default PrintComponent;
In this example, we have a ComponentToPrint
component that we want to print. We create a new PrintComponent
that wraps ComponentToPrint
with the ReactToPrint
component. We pass the ComponentToPrint
as content to the ReactToPrint
component using a ref.
We also specify a trigger
that will trigger the print dialog when clicked. In this case, we're using a button
element.
React Print provides several options to customize the printing experience. Here are some of the options you can use:
copyStyles
: Copies the styles from the element being printed.onBeforeGetContent
: A callback that is called before getting the content to be printed.onAfterPrint
: A callback that is called after the content has been printed.onBeforePrint
: A callback that is called before the content is printed.removeAfterPrint
: Removes the content from the DOM after printing.You can pass these options as props to the ReactToPrint
component, like this:
<ReactToPrint
trigger={() => <button>Print</button>}
content={() => this.componentRef}
copyStyles={true}
onBeforeGetContent={() => console.log('Getting content to print')}
onAfterPrint={() => console.log('Print job has finished')}
onBeforePrint={() => console.log('Print job is starting')}
removeAfterPrint={true}
/>
React Print is a great library for adding print functionality to your React application. It's easy to use and provides a lot of customization options. Give it a try the next time you need to add print functionality to your project.
