PDFSlick is a library that enables viewing of and interaction with PDF documents in React, SolidJS, Svelte and JavaScript apps.
It's build on top of Mozilla's [PDF.js](https://github.com/mozilla/pdf.js), and utilises [Zustand](https://github.com/pmndrs/zustand) to provide a reactive store for the loaded documents.
## PDFSlick for React
To get started with React run:
```shell
npm install @pdfslick/react
# yarn add @pdfslick/react
# pnpm add @pdfslick/react
```
You can start using PDFSlick with the `usePDFSlick()` hook, like with the following basic example:
```jsx
import { usePDFSlick } from "@pdfslick/react";
import PDFNavigation from "./yourcomponents/PDFNavigation";
//
// It is required to include PDFSlick's CSS styles once
// you can do it in your main `App.tsx` for example
//
import "@pdfslick/react/dist/pdf_viewer.css";
type PDFViewerComponentProps = {
pdfFilePath: string,
};
const PDFViewerComponent = ({ pdfFilePath }: PDFViewerComponent) => {
const { viewerRef, usePDFSlickStore, PDFSlickViewer } = usePDFSlick(
pdfFilePath,
{
scaleValue: "page-fit",
}
);
/*
Access the store with `usePDFSlickStore()` hook — you can pass is
as a prop to other components (like with `` below)
Toolbars, Sidebars, components which render thumbnails etc.
and use it as here to get and react on
PDF document's and viewer's properties and changes
*/
const scale = usePDFSlickStore((s) => s.scale);
const numPages = usePDFSlickStore((s) => s.numPages);
const pageNumber = usePDFSlickStore((s) => s.pageNumber);
return (
{/*
Pass PDFSlick's store to your custom components
*/}
{/*
PDFSlick's store values automatically update
*/}
Current scale: {scale}
Current page number: {pageNumber}
Total number of pages: {numPages}
);
};
export default PDFViewerComponent;
```
Provided with the PDF Document path and PDFSlick options object, the `usePDFSlick()` hook returns an object consisting (among the other things) of:
- `PDFSlickViewer` is the PDF Viewer component used for viewing the PDF document
- `viewerRef` is the `ref` callback that is provided as a prop to the `` component
- `usePDFSlickStore` enables using PDFSlick store within your React components

## PDFSlick for SolidJS
To get started with PDFSlick for SolidJS run:
```shell
npm install @pdfslick/solid
# yarn add @pdfslick/solid
# pnpm add @pdfslick/solid
```
You can start using PDFSlick with the `usePDFSlick()` hook, like with the following basic example:
```jsx
import { Component, createSignal } from "solid-js";
import { usePDFSlick } from "@pdfslick/solid";
import PDFNavigation from "./yourcomponents/PDFNavigation";
//
// It is required to include PDFSlick's CSS styles once
// you can do it in your main `App.tsx` for example
//
import "@pdfslick/solid/dist/pdf_viewer.css";
type PDFViewerComponentProps = {
pdfFilePath: string,
};
const PDFViewerComponent: Component = ({
pdfFilePath,
}) => {
const {
viewerRef,
pdfSlickStore: store,
PDFSlickViewer,
} = usePDFSlick(pdfFilePath);
return (
{/*
Pass PDFSlick's store to your custom components (like the `` below) —
Toolbars, Sidebars, components which render thumbnails etc.
and use it as here to get and react on
PDF document and viewer properties and changes
*/}
{/*
PDFSlick's store values automatically update
*/}
Current scale: {store.scale}
Current page number: {store.pageNumber}
Total number of pages: {store.numPages}
);
};
export default PDFViewerComponent;
```
Provided with the PDF Document path and options object, the `usePDFSlick()` hook returns an object consisting (among the other things) of:
- `PDFSlickViewer` is the PDF Viewer component used for viewing the PDF document
- `viewerRef` is the `ref` callback that is provided as a prop to the `` component
- `pdfSlickStore` is the PDFSlick store

## PDFSlick for Svelte
To get started with PDFSlick for Svelte run:
```shell
npm install @pdfslick/core
# yarn add @pdfslick/core
# pnpm add @pdfslick/core
```
You can load a PDF document and subscribe to a portion of or the entire PDFSlick store's state, like in the following basic example:
```html
import type { PDFSlick } from '@pdfslick/core';
import { onMount, onDestroy } from 'svelte';
// ...
/**
* Reference to the PDF Viewer container
*/
let container: HTMLDivElement;
/**
* Reference to the pdfSlick instance
*/
let pdfSlick: PDFSlick;
/**
* Keep PDF Slick state portions we're interested in using in your app
*/
let pageNumber = 1;
let numPages = 0;
onMount(async () => {
/**
* This is all happening on client side, so we'll make sure we only load it there
*/
const { create, PDFSlick } = await import('@pdfslick/core');
/**
* Create the PDF Slick store
*/
const store = create();
pdfSlick = new PDFSlick({
container,
store,
options: {
scaleValue: 'page-fit'
}
});
/**
* Load the PDF document
*/
pdfSlick.loadDocument(url);
store.setState({ pdfSlick });
/**
* Subscribe to state changes, and keep values of interest as reactive Svelte vars,
* (or alternatively we could hook these or entire PDF state into a Svelte store)
*
* Also keep reference of the unsubscribe function we call on component destroy
*/
unsubscribe = store.subscribe((s) => {
pageNumber = s.pageNumber;
numPages = s.numPages;
});
});
onDestroy(() => unsubscribe());
// ...
pdfSlick?.gotoPage(Math.max(pageNumber - 1, 1))}
disabled={pageNumber <= 1}
>
Show Previous Page
pdfSlick?.gotoPage(Math.min(pageNumber + 1, numPages))}
disabled={pageNumber >= numPages}
>
Show Next Page
```

## Motivation
[PDF.js](https://github.com/mozilla/pdf.js) is an amazing piece of software. It is also a very stable and mature one — it powers the PDF viewer in Mozilla Firefox and it's been around since 2011. However, it's all Vanilla JavaScript, and when it comes to using it with libraries like React and SolidJS (although possible) it's a litte bit hard in terms of integrating it in these Component- and reactive-like environments. PDFSlick attempts to wrap all of that fascinating functionality into one that is easier to fit in React and SolidJS worlds — as components and a reactive store.
## Core Concepts
The core of PDFSlick is within the `@pdfslick/core` package. It wraps `PDF.js`'s functionality and links it to the store. This `@pdfslick/core` package is the basis for the React and SolidJS packages, which additionally transform the store and make it suitable for the adequate library, as well as providing components for the PDF viewer and thumbnails.
Depending on your needs, at this you might find it useful to continue with learning more about using PDFSlick with React and SolidJS respsectivelly. However, if really interested you can learn more about using PDFSlick's `@pdfslick/core` package with Vanilla JS apps and with libraries other than React and SolidJS in the sections below.
