Illustration: How to Build a Laravel Image Viewer with PSPDFKit

In this post, we provide you with a step-by-step guide outlining how to deploy PSPDFKit’s Laravel image viewer.

Laravel is an MVC framework for PHP. It builds on top of PHP standards and conventions, making it easier for developers to create completely customizable, full-featured apps.

What Is a Laravel Image Viewer?

A Laravel image viewer uses Laravel to render and view image documents in a web browser without the need to download it to your hard drive or use an external application like an image reader.

PSPDFKit Laravel Image Viewer

We offer a commercial Laravel image viewer library that can easily be integrated into your web application. It comes with 30+ features that let you view, annotate, edit, and sign documents directly in your browser. Out of the box, it has a polished and flexible UI that you can extend or simplify based on your unique use case.

  • A prebuilt and polished UI
  • 15+ annotation tools
  • Support for multiple file types
  • Dedicated support from engineers

Example of Our Laravel Image Viewer

To see our image viewer in action, upload a JPG, PNG, or TIFF file by selecting Choose Example > Open Document. Once your image is displayed in the viewer, you can try drawing freehand, adding a note, or applying a crop or an e-signature.

Requirements to Get Started

To get started, you’ll need:

You can install PHP via XAMPP, MAMP, or Homebrew.

Don’t forget to add composer to your path directory:

export PATH="$HOME/.composer/vendor/bin:$PATH"

Creating the Project

  1. Create a new Laravel project:

laravel new pspdfkit-app
  1. Change to the created project directory:

cd pspdfkit-app

Adding PSPDFKit to Your Project

PSPDFKit for Web library files are distributed as an archive that can be extracted manually.

  1. Download the framework here. The download will start immediately and will save a .tar.gz archive like PSPDFKit-Web-binary-2022.2.1.tar.gz to your computer.

  2. Once the download is complete, extract the archive to your computer.

  3. Create a new directory under public called assets, and copy the entire contents of its dist folder to your project’s public/assets folder.

Make sure your assets folder contains the pspdfkit.js file and a pspdfkit-lib directory with the library assets.

Integrating into Your Project

  1. Add the image you want to display to the public folder. You can use our demo image as an example.

  2. Navigate to the resources/views/welcome.blade.php file.

  3. Add an empty <div> element with a defined height to where PSPDFKit will be mounted:

<div id="pspdfkit" style="height: 100vh"></div>
  1. Include pspdfkit.js on the welcome.blade.php file:

<script src="assets/pspdfkit.js"></script>
  1. Initialize PSPDFKit for Web in Laravel by calling PSPDFKit.load():

<script>
	PSPDFKit.load({
		container: "#pspdfkit",
  		document: "image.png" // Add the path to your image here.
	})
	.then(function(instance) {
		console.log("PSPDFKit loaded", instance);
	})
	.catch(function(error) {
		console.error(error.message);
	});
</script>

You can see the full welcome.blade.php file (which is just a plain HTML file):

<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="UTF-8">
		<meta http-equiv="X-UA-Compatible" content="IE=edge">
		<meta name="viewport" content="width=device-width, initial-scale=1.0">
		<title>Document</title>
	</head>
	<body>
 		<!-- Element where PSPDFKit will be mounted. -->
		<div id="pspdfkit" style="height: 100vh"></div>

		<script src="assets/pspdfkit.js"></script>

		<script>
			PSPDFKit.load({
				container: "#pspdfkit",
				document: "image.png", // Add the path to the image here.
			})
			.then(function(instance) {
				console.log("PSPDFKit loaded", instance);
			})
			.catch(function(error) {
				console.error(error.message);
			});
		</script>
	</body>
</html>

Serving Your Website

  1. Go to your terminal and run a server with this command:

php artisan serve
  1. Navigate to http://127.0.0.1:8000 to view the website.
