To implement a PDF preview in Angular, you can use the pdf.js library. Here’s a basic example of how you can do it: Install pdf.js : You can add it to your project using npm: npm install pdfjs-dist Import pdf.js in your component : import * as PDFJS from 'pdfjs-dist'; Fetch the PDF from the API and display it : Assuming you have a function getPdfUrl() that returns the URL of the PDF from your API, you can use the following code to fetch the PDF and display it: let loadingTask = PDFJS.getDocument(this.getPdfUrl()); loadingTask.promise.then(pdf => { console.log('PDF loaded'); // Fetch the first page let pageNumber = 1; pdf.getPage(pageNumber).then(page => { console.log('Page loaded'); let scale = 1.5; let viewport = page.getViewport({scale: scale}); // Prepare canvas using PDF page dimensions let canvas = document.getElementById('the-canvas'); let context = canvas.getContext('2d'); canvas.height = viewport.height; canvas.width = viewport.width; // Render PDF page into canvas context let renderContext = { canvasContext: context, viewport: viewport }; let renderTask = page.render(renderContext); renderTask.promise.then(() => { console.log('Page rendered'); }); }); }, function (reason) { // PDF loading error console.error(reason); }); In this example, replace 'the-canvas' with the id of your canvas element. This code will fetch the PDF from the API, load it, and render the first page to a canvas element. Thanks

I need more information about your setup and goals: 1. Programming Language and Framework: What programming language and framework are you using for your project (e.g., Java/Android, Kotlin/Android, React Native, Flutter, etc.)? Knowing this will help tailor the solution to your environment. 2. API Details: What type of API are you using for the PDF preview? Is it a dedicated PDF preview API, a generic file preview API, or something else? Understanding the API's capabilities and functionalities is essential. How does the API provide the PDF for preview? Does it directly return the PDF content, a URL, or something else? This will determine how to fetch and handle the PDF. 3. Naming Mechanism: How do you intend to use the API-provided name for the PDF preview? For example, do you want to display it alongside the preview, use it to generate a temporary file name, or something else? Clarifying this helps guide the approach.
