Step-by-step guide for adding PDF viewing, editing, and annotation features." --- # Add PDF viewing and editing to Vue applications Nutrient Web SDK is a JavaScript PDF library for viewing, annotating, and editing PDFs directly in the browser. Use it to add PDF capabilities to any web app. This guide walks you through the steps to integrate Nutrient Web SDK into your project. By the end, you’ll be able to render a PDF document in the user interface (UI). **Test without installing** You can test the SDK capabilities in our playground.

Nutrient maintains the CDN for customers, and it’s our recommended way to get started. For more control and flexibility, use the local installation option. #### Note: Creating a new project (optional) If you don’t yet have a Vue project set up, create one with Vite: ```sh pnpm create vite nutrient-vue-example --template vue ``` ### CDN installation **Steps:** 1. Add the following in your `index.html` file: ```html // index.html Vite App

``` 2. You’re now ready to use Nutrient Web SDK and reference `window.NutrientViewer` in the client-side code. ### Install via package manager **Steps:** 1. Add the Nutrient Web SDK (`@nutrient-sdk/viewer`) dependency: ```bash npm install @nutrient-sdk/viewer # or yarn add @nutrient-sdk/viewer # or pnpm install @nutrient-sdk/viewer ``` 2. If you tried CDN installation first, make sure to remove the script tag: ```html

``` 3. You’re now ready to use Nutrient Web SDK locally in your Vue + Vite app. ## Rendering a PDF ### CDN installation **Steps:** 1. Load the PDF file in `App.vue`: ```vue // App.vue ``` 2. Start the development server: ```bash npm run dev # or yarn dev # or pnpm dev ``` 3. You’ll see the PDF rendered in the Nutrient Web SDK user interface (UI). ### Install via package manager **Steps:** 1. With package manager installation, access the Nutrient Web SDK module directly. Update your `App.vue` to load the PDF file as shown below: ```vue // App.vue ``` > **Note:** Adding `useCDN: true` will load the SDK assets from the CDN if `baseUrl` isn’t provided. This flag was introduced in version 1.9.0. If your setup relies on the previous behavior of autodetecting the assets without `baseUrl`, you can omit this flag for now, but be aware that this behavior is deprecated. In future versions, loading from CDN will become a default when `baseUrl` isn’t explicitly provided. `useCDN: true` has no effect if `baseUrl` is set. **Optional**: If you decide to self-host the Nutrient Web SDK assets as [described in this guide](https://www.nutrient.io/guides/web/self-host-assets.md), make sure to provide a `baseUrl` in your configuration, as shown below: ```vue NutrientViewer.load({ container, useCDN: true, document: "https://www.nutrient.io/downloads/nutrient-web-demo.pdf", baseUrl: `${window.location.protocol}//${window.location.host}/${ import.meta.env.PUBLIC_URL?? "" // Usually empty for Vite, but supports custom deployments. }`, }); ``` 2. Start the development server: ```bash npm run dev # or yarn dev # or pnpm dev ``` ## Next steps This section outlines additional steps for setting up your project. ### TypeScript with CDN installation Nutrient Web SDK comes with built-in support for TypeScript. This should work out of the box for the package manager installation. For the CDN installation, follow the steps below. **Steps:** 1. Add the Nutrient Web SDK dependency, if not done previously. You need the package installed locally to reference the types: ```bash npm install @nutrient-sdk/viewer # or yarn add @nutrient-sdk/viewer # or pnpm install @nutrient-sdk/viewer ``` 2. Create a module for custom typings — for example, `global.d.ts` in the `src` directory — to reference the built-in typings for the SDK: ```ts // src/global.d.ts import NutrientViewer from "@nutrient-sdk/viewer"; declare global { interface Window { // Nutrient Web SDK will be available on `window.NutrientViewer` once loaded. NutrientViewer?: typeof NutrientViewer; } } ``` 3. Restart the TypeScript server or your editor, if needed. ### Optimizing the CDN installation If you use the CDN installation approach in production, we recommend considering optimizations such as [prefetching](https://developer.mozilla.org/en-US/docs/Glossary/Prefetch). ### Optimizing load performance If your app doesn't open a PDF immediately — for example, the user navigates to a viewer on a different page — call [`NutrientViewer.preloadWorker()`](https://www.nutrient.io/api/web/functions/NutrientViewer.preloadWorker.html) early in your app to fetch and compile the WebAssembly artifacts in the background. When `NutrientViewer.load()` runs later, it can start rendering without waiting for them. ```js // Call early — for example, on app init or after login. NutrientViewer.preloadWorker(); ``` Refer to the [performance best practices](https://www.nutrient.io/guides/web/best-practices/performance.md) guide for more optimization techniques. ## Troubleshooting If you encounter issues, refer to the [common issues](https://www.nutrient.io/guides/web/troubleshooting/common-issues.md) guide. > **Note for developers using AI coding assistants**: To get accurate troubleshooting help, copy the content from the [troubleshooting](https://www.nutrient.io/guides/web/troubleshooting/common-issues.md) guide and include it in your prompt, along with your specific error. **Test without installing** You can test the SDK capabilities in our playground.
