How to use react-to-print in react.js

Hi, y'all this is probably the simplest way to go when you're trying to add a download page functionality in react.

In this article, I'll be showing you how to implement pdf downloads from your react project using either class or functional components.

Installations

I assume you have your react project installed.

Now go ahead and add the packages

yarn add react-to-print

or

npm i react-to-print

Using functional components

Now we can go to our App.js component or any file you intend to use and import your package like so.

import React, { useRef } from 'react';
import ReactToPrint from 'react-to-print';

const App = () => {
  const componentRef = useRef();

  return (
    <div>
      <div ref={componentRef}>This contains all the files you intend to export[download]</div>
      <ReactToPrint
        trigger={() => <button>Print this out!</button>}
        content={() => componentRef.current}
      />
    </div>
  );
};
export default App;

Voila! However, you might want to be passing the component from another file, then you'll have to pass the ref as a prop.

Using class component

Following the same method as the first approach, go to your desired file and follow the technique below.

import React from "react";
import ReactToPrint from "react-to-print";

class App extends React.Component {
  render() {

    return (
      <div>
        <div ref={(refer) => (this.componentRef = refer)}>Export my HTMl component to a PDF File</div>

        <ReactToPrint
          content={() => this.componentRef}
          trigger={() => (
            <button className="btn btn-primary">Print to PDF!</button>
          )}
        />
      </div>
    );
  }
}

export default Appp;

Note when using an external file you'll just have to pass the ref directly into the component you're calling like so <ImportedComponent ref={(response) => (this.componentRef = response)} /> and yeah you're all good to go.

You're welcome.
