Welcome to Apryse. This guide will help you integrate a free trial of WebViewer into Svelte applications on the browser. It will help you clone the Svelte sample repository, walk through the project structure, and show you how to call other WebViewer API. Your free trial includes unlimited trial usage and support from solution engineers.

Get the Svelte sample source code here

• Node.js and npm

1. Clone the Svelte sample by executing

   git clone https://github.com/PDFTron/webviewer-svelte-sample.git

2. Once cloned, navigate into the webviewer-svelte-sample folder and install all the required dependencies by executing

   npm install

npm will also download the Apryse WebViewer and extract it to /public/lib.

You are now ready to run the sample or use more WebViewer APIs.

After initial setup, your webviewer-svelte -sample directory should be laid out like this:

webviewer-svelte-sample
├── LICENSE
├── node_modules
│   └── ...
├── package.json
├── package-lock.json
├── public
│   ├── bundle.css
│   ├── bundle.css.map
│   ├── bundle.js
│   ├── bundle.js.map
│   ├── favicon.png
│   ├── global.css
│   ├── index.html
│   └── lib
├── README.md
├── rollup.config.js
└── src
    ├── App.svelte
    ├── main.js
    └── WebViewer.svelte

Notable files and directories include:

To run the sample, navigate to your /webviewer-svelte-sample directory and execute

npm run dev

Then navigate to http://localhost:5000. You should see WebViewer start up and load the sample PDF. Note it will change in real time if you edit any of the source files.

To call more WebViewer API's, navigate to /src/WebViewer.svelte and add the API calls in the callback of the WebViewer constructor(you may need to make one if it is not provided).

const ele = document.getElementById('viewer');
window.WebViewer({
  path: '/lib'
}, ele)
  .then(instance => {
    // In this callback WebViewer will be initialized, so you can call WebViewer API here.
    instance.UI.setTheme('dark');
  });

If your Svelte application is already running, you should see the theme change right away. Otherwise execute npm run dev again, then navigate to http://localhost:5000 and you should see that the theme has changed.
