pdfjs uses a web worker to process the most tasks which take time such as parsing and rendering a PDF document.The web worker is loaded via the `workerUrl` parameter:
It's very important to note that the worker version and the `pdfjs` package (mentioned in the Install pdfjs librarysection of Getting started) have to be the same.
This guide uses the pdfjs v3.4.120.Otherwise, you will see the error message like this:
TheAPI version "3.4.120" does not match the Worker version "2.6.347"
at Worker.MessageHandler._onComObjOnMessage(pdf.js:6846)
However, if you use the Webpack bundler, setting the same version for both worker and the `pdfjs-dist` package can be automated.There are two ways to archive that:
When the worker is ready, it's time to use the viewer component. To display a PDF document, you have to pass its URL tothe viewer's `fileUrl` parameter:
The `fileUrl` accepts various sources of documents, including a base 64 string, an array of bytes, or a URL.It's possible to view a document from a remote server as long as the server allows us to access the document.
By default, the viewer will take the full size of its container. Hence you have to indicate the height of element that you wouldlike to display the document:
Congratulation! Now you know how to use the main viewer component to display a PDF document.
By default, the `Viewer` component does not come with other parts such as toolbar and sidebar.If you want to have a full features viewer, please use the default-layout plugin.
There's no need to call StyleSheet.create in order to style components. You can also just pass a plain JS object to the style prop and react-pdf will get the job done.
A PDF Reader is a software program that allows you to open and view PDF (Portable Document Format) files. The most basic function of a PDF reader is to present the content of a PDF file in a readable format. This includes text, images, links, and all other elements that might be included in a PDF.
As a rule of thumb for our team at Finnovate.io, if a React component has more than 200 lines of code, then it is too big. Big components are difficult to read, difficult to maintain and nearly impossible to unit test. Fortunately, it is not so hard to abstract code away from components with a few pointers.
React apps are easy to scale thanks to modular nature — components are easy to extract, merge, and reuse. React's modular architecture simplifies its maintenance.
import React from 'react'; import Pdf from './Pdf' const App = ()=> { return ( <div className="App"> //Rendering a pdf component <Pdf /> </div> ); } export default App; After creating a pdf component your project directory will look like this. Step 4: In this section, we load the PDF and render it on your app.
React-PDF is a unique library that provides powerful functionality for creating PDF files using React components. Instead of manually writing your document structure in a JavaScript object, you can create your PDF just like you would build a typical React application - using reusable components and props.
The simplest way to display a PDF document in React is by using the `<iframe>` element. You can embed the PDF file within an `<iframe>` tag and set the source to the URL of the PDF file.
Using an iframe tag is the second way to embed a pdf file in an HTML web page. In web development, web developers use the iframe tag to embed files in various formats and even other websites within a web page. Due to its wide compatibility, the iframe tag is widely used for embedding pdf.
Using the React File Viewer in your project is straightforward. First, you need to import the library into your project. Once you've imported the React File Viewer, you can use it to render files. You simply need to pass the file and its type as parameters to the FileViewer component.
