+This guide explains how to integrate the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) into an Angular application that runs in the browser. The generated PDF is downloaded directly from the browser; no server-side PDF rendering is involved.
 
-## Setup Angular Environment
+## Prerequisites
 
-You can use the [Angular CLI](https://github.com/angular/angular-cli) to setup your Angular applications.
-To install the latest Angular CLI globally use the following command.
+Before you begin, make sure you have the following installed:
+
+- Angular 20 or later.
+- Node.js 18 or later.
+- npm 9 or later, or Yarn 1.22 or later.
+- Visual Studio Code or another code editor.
+- A supported browser such as the latest versions of Microsoft Edge, Google Chrome, or Mozilla Firefox.
+
+To verify your Node.js and npm versions, run the following commands:
 
 ```bash
-npm install -g @angular/cli
+node --version
+npm --version
 ```
 
-N> To install a specific Angular CLI version, use: **npm install --save @angular/cli@12.0.2**
+## Project Setup
+
+This guide includes all the steps needed to create and run the sample in an Angular application. You can either create a new project or use an existing one.
+
+### Option A: Create a New Angular Project
+
+If you do not have an Angular project, create one by using the Angular CLI:
+
+```bash
+npm install -g @angular/cli
+ng new my-pdf-app
+cd my-pdf-app
+```
 
-## Create an Angular Application
+### Option B: Use an Existing Angular Project
 
-Start a new Angular application using the Angular CLI command as follows.
+If you already have an Angular project, open its root folder and continue with the package installation steps:
 
 ```bash
-ng new my-app
-cd my-app
+cd path/to/your-existing-app
 ```
 
-## Installing JavaScript PDF package
+## Installing the JavaScript PDF Library package
 
-All Syncfusion<sup>&reg;</sup> JS 2 packages are published in `npmjs.com` registry.
+All Syncfusion<sup>&reg;</sup> JS 2 packages are published in `npmjs.com` registry. The `npm install` command below resolves `@syncfusion/ej2-pdf` to the latest stable version that is compatible with Angular 20 or later.
 
-* To install PDF component, use the following command.
+* To install the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library), use the following command.
 
 ```bash
 npm install @syncfusion/ej2-pdf --save
 ```
-N> For image and data extraction features, you need to install the `@syncfusion/ej2-pdf-data-extract` package as an add-on.
-* Copy the `ej2-pdf-lib` folder from the @syncfusion/ej2-pdf-data-extract package into your project's **public, dist, or assets** directory (where your static files are served).
-* Make sure the `ej2-pdf-lib` folder exists in your final build output if you need to extract images or data from PDF files.
-* Ensure your server serves .wasm files with the **Content-Type: application/wasm** MIME type.
-(Angular’s development server already handles this; configure production servers manually.)
-* This setup is not required for **basic PDF creation**.
 
-## Create a PDF document
+* If you prefer Yarn, use the following command.
+
+```bash
+yarn add @syncfusion/ej2-pdf
+```
+
+N> For image and data extraction features, you need to install the `@syncfusion/ej2-pdf-data-extract` package as an add-on. Note the following:
+- Copy the `ej2-pdf-lib` folder from the `@syncfusion/ej2-pdf-data-extract` package into your project's **public**, **dist**, or **assets** directory (wherever your static files are served).
+- Make sure the `ej2-pdf-lib` folder exists in your final build output if you need to extract images or data from PDF files.
+- Ensure your server serves `.wasm` files with the **Content-Type: application/wasm** MIME type. Angular's development server already handles this; configure production servers manually.
+- This setup is not required for **basic PDF creation**.
+
+## Add the Syncfusion License Key
+
+If your project requires a Syncfusion license, register the license key before using the PDF API. Add the license registration code in your startup file, such as `main.ts`.
 
-* Add a simple button to `app.component.html` and attach a click handler that uses the TypeScript PDF API to create a new PDF document.
+```ts
+import { registerLicense } from '@syncfusion/ej2-base';
+
+registerLicense('YOUR_LICENSE_KEY');
+```
+
+Replace `YOUR_LICENSE_KEY` with the key from your Syncfusion account. For more information, see the [Syncfusion licensing documentation](https://help.syncfusion.com/document-processing/licensing/overview).
+
+## Browser and Environment Compatibility
+
+| Environment | Supported version |
+| --- | --- |
+| Angular | 20 or later |
+| Node.js | 18.x or later |
+| TypeScript | Installed with Angular |
+| Visual Studio Code | Latest version recommended |
+| Chrome | Latest two major versions |
+| Edge | Latest two major versions |
+| Firefox | Latest two major versions |
+
+> For server-side rendering or Angular Universal, create the PDF document only in browser execution paths. The sample in this guide uses a click handler that runs in the browser, so no additional lifecycle handling is required.
+
+## Create a PDF Document
+
+Add a button to the Angular template and attach a click handler that uses the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) to create a new PDF document.

+- `drawString(text, font, layoutRect, brush)` — draws the text inside the rectangle defined by `x`, `y`, `width`, and `height`.
+- `save('Output.pdf')` — saves the PDF and triggers a browser download with the specified file name. The file is sent to the browser's default downloads folder.
+- `destroy()` — releases native resources held by the document.
 
-Use the following command to run the application in browser.
+## Run the Application
+
+Use the following command to run the application in the browser:
 
 ```bash
 ng serve --open
 ```
 
-By executing the program, you will get the PDF document as follows.
+When you click **Create PDF document**, the PDF file is generated in the browser and downloaded as `Output.pdf` to your default downloads folder.
+

+
+## Troubleshooting
+
+| Problem | Cause | Resolution |
+|---|---|---|
+| `TS2304: Cannot find name 'PdfDocument'` (or similar) | The import line is missing or the package is not installed | Confirm `npm install @syncfusion/ej2-pdf` ran successfully and that the import is in `app.component.ts` |
+| `Error: Cannot find module '@syncfusion/ej2-pdf'` | The package is not installed | Run `npm install @syncfusion/ej2-pdf --save` |
+| Button click does nothing | The button ID does not match the ID used in `getElementById` | Confirm the button's `id` is `normalButton` |
+| PDF file does not download | The browser blocks the download | Check the browser's download settings and the downloads folder |
+| Build fails with TypeScript errors | The Angular TypeScript version is incompatible with the PDF package | Update Angular to 20 or later and run `npm install` again |
+| `registerLicense` warning at runtime | The license key is missing or invalid | Confirm the key is set in `main.ts` and is the correct key for your Syncfusion account |

+## Additional Configuration
+
+N> For image and data extraction features, install the `@syncfusion/ej2-pdf-data-extract` package as an add-on (NPM approach), then copy the `ej2-pdf-lib` folder from `node_modules/@syncfusion/ej2-pdf-data-extract/dist/ej2-pdf-lib` into a publicly accessible location under `wwwroot/` (for example, `wwwroot/lib/ej2-pdf-lib/`). The folder must contain the required `.js` and `.wasm` files. This setup is not required for **basic PDF creation** as shown in this guide.
+
+## Troubleshooting
 
-Step 8: **Run the project**: Click the Start button (green arrow) or press F5 to run the app.
+| Problem | Cause | Resolution |
+|---|---|---|
+| `ej is not defined` in the browser console | The CDN script tag is missing or blocked | Confirm the `<script>` reference in `_Layout.cshtml` is reachable and not blocked by an ad blocker or network policy |
+| Button click does nothing | The click handler is rendered before the button exists, or `@section Scripts` is missing in the layout | Confirm `_Layout.cshtml` contains `@await RenderSectionAsync("Scripts", required: false)` |
+| `SyntaxError: Unexpected token ':'` | TypeScript annotations were left inside a plain `<script>` block | Remove the `: ej.pdf.PdfType` annotations; the script must be plain JavaScript |
+| `Failed to load resource: 404` on `ej2.min.js` | The CDN version path is incorrect or the network is restricted | Verify the CDN URL and internet access; switch to the [NPM](https://ej2.syncfusion.com/aspnetcore/documentation/common/adding-script-references#node-package-manager-npm) or [CRG](https://ej2.syncfusion.com/aspnetcore/documentation/common/custom-resource-generator) approach if the CDN is not reachable |
+| `output.pdf` does not download | The browser blocks the download | Check the browser's download settings and the downloads folder |
+| `WASM` or `.js` 404s for data extraction | The `ej2-pdf-lib` folder is not under `wwwroot/` | Copy the `ej2-pdf-lib` folder from the `@syncfusion/ej2-pdf-data-extract` package into `wwwroot/lib/` |
+| CDN version mismatch with NuGet/npm packages | The CDN version is out of sync with the installed Syncfusion packages | Use the same Syncfusion version across CDN and NuGet/npm packages |

-Syncfusion<sup>&reg;</sup> JS 2 (global script) is an ES5-formatted [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) that works directly in modern web browsers.
+Syncfusion<sup>&reg;</sup> JS 2 (global script) is an ES5-formatted distribution of the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) that runs directly in any modern web browser without a build step or bundler. The all-in-one `ej2.min.js` bundle exposes the `ej.pdf` namespace, which contains the PDF document, page, graphics, font, and brush classes.
 
-## Component initialization with CDN links
+This guide explains how to integrate the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) into a static HTML page. The generated PDF is downloaded directly from the browser; no server-side PDF rendering is required.
 
-Step 1: Create a folder named `my-app` for your project.
+## Prerequisites
+
+Before you begin, make sure you have the following:
+
+- A modern web browser such as the latest versions of Microsoft Edge, Google Chrome, Mozilla Firefox, or Safari.
+- A static file server. The page must be served over `http://` or `https://` (not opened directly from disk) because the CDN scripts and the PDF download use APIs that are restricted under the `file://` protocol.
+- A text editor such as Visual Studio Code, Code Studio, or Notepad.
+
+Common static-server options include:
+
+- **Node.js** (recommended): `npx serve` (no install required)
+- **Python 3**: `python -m http.server 8000`
+- **VS Code**: the [Live Server](https://marketplace.visualstudio.com/items?itemName=ritwickdey.LiveServer) extension
 
-Step 2: The JS 2 global scripts and styles are hosted on the CDN in the following formats.
+## CDN Syntax

+
+## Code Explanation
+
+- `ej.pdf.PdfDocument` — creates a new PDF document instance.
+- `addPage()` — appends a blank page to the document and returns the `PdfPage` object.
+- `page.graphics` — returns the `PdfGraphics` drawing surface for the page.
+- `embedFont(family, size, style)` — embeds one of the standard PDF font families (here, Helvetica 36pt regular) and returns a `PdfStandardFont` object.
+- `new ej.pdf.PdfBrush({ r, g, b })` — creates a solid color brush from an RGB object (each channel `0`-`255`); here, black.
+- `drawString(text, font, layoutRect, brush)` — draws the text inside the rectangle defined by `x`, `y`, `width`, and `height`. The layout rect is `{ x, y, width, height }`.
+- `graphics.clientSize.width` — the writable width of the page in points.
+- `save('Output.pdf')` — saves the PDF and **triggers a client-side browser download** with the specified file name. The file is sent to the browser's default downloads folder; nothing is written to the server.
+- `destroy()` — releases native resources held by the document.
+
+## Run the Sample
+
+Step 4: Open a terminal in the `my-app` folder and start a static file server.
+
+Using `npx serve` (no install required):
+
+```bash
+npx serve
+```
+
+Or using Python 3:
+
+```bash
+python -m http.server 8000
+```
+
+Step 5: Open the served URL in your browser. For `npx serve`, the default URL is `http://localhost:3000`. For Python, the default URL is `http://localhost:8000`.
+
+Click **Generate PDF document**. The browser downloads `Output.pdf`, which contains a single page with the text "Hello World!!!" drawn at the top-left.
+
+![Output PDF document](Getting_started_images/Output.png)
+
+## Additional Configuration (Optional)
+
+N> The following steps are required **only** if you need image or data extraction features. They are not required for the basic PDF creation shown in this guide.
+
+If you need image and data extraction, install the data-extraction add-on and copy the `ej2-pdf-lib` folder into the served directory.
+
+1. Install the add-on package:
+
+   ```bash
+   npm install @syncfusion/ej2-pdf-data-extract --save
+   ```
+
+2. Copy the `ej2-pdf-lib` folder from `node_modules/@syncfusion/ej2-pdf-data-extract/dist/ej2-pdf-lib` into the same folder as `index.html`. The folder must contain the required `.js` and `.wasm` files.
+
+3. Confirm that the `ej2-pdf-lib` folder is reachable from the served page (for example, at `http://localhost:3000/ej2-pdf-lib/`).
+
+## License Registration
+
+N> This guide uses the CDN distribution of the JavaScript PDF Library. No client-side `registerLicense` call is required when loading the library from the Syncfusion CDN; licensing is handled at the account level. If you switch to the NPM-based packages, add a `registerLicense('YOUR_LICENSE_KEY')` call in your entry script.
+
+## Troubleshooting
+
+| Problem | Cause | Resolution |
+|---|---|---|
+| `ej is not defined` in the browser console | The CDN script tag is missing or blocked | Confirm the `<script src="https://cdn.syncfusion.com/ej2/.../ej2.min.js"></script>` reference is reachable and not blocked by an ad blocker or network policy |
+| `@section Scripts` appears as plain text on the page | The file is a static `.html`, not an ASP.NET view | Replace the Razor block with a plain `<script>` tag inside `<body>` |
+| Button click does nothing | The script runs before the button is in the DOM | Move the `<script>` tag to the end of `<body>`, or wrap the listener in a `DOMContentLoaded` event |
+| `Output.pdf` does not download | The browser blocks the download | Check the browser's download settings and the downloads folder |
+| CORS or `file://` errors | The page is opened directly from disk | Serve the folder over `http://` using `npx serve` or a similar static server |
+| `WASM` or `.js` 404s for data extraction | The `ej2-pdf-lib` folder is not in a public location | Copy the `ej2-pdf-lib` folder from the `@syncfusion/ej2-pdf-data-extract` package into the served folder |
+| CDN version mismatch with other Syncfusion packages | The CDN version is out of sync with installed Syncfusion packages | Use the same Syncfusion version across CDN and any other Syncfusion packages you reference |

 # Create or Generate a PDF File in a Node.js Server Environment
 
-The [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) is used to create, read, and edit PDF documents. The [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) also offers functionality to merge, split, stamp, fill forms, and secure PDF files.

+This guide explains how to integrate the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) into a Node.js server-side application that exposes a PDF generation endpoint and delivers the file to the browser.
 
-## Installing the JavaScript PDF Library package
+## Prerequisites
 
-All Syncfusion JS 2 packages are published in `npmjs.com` registry.
+The following prerequisites are required to complete this guide:
 
-* To install the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library), use the following command.
+- **Node.js** version 18.0 or later
+- **npm** version 9.0 or later
+- A code editor such as Visual Studio Code
+- Basic familiarity with Node.js and the command line
+
+To verify your Node.js and npm versions, run the following commands:
 
 ```bash
-npm install @syncfusion/ej2-pdf --save
+node --version
+npm --version
 ```
 
-N> For data extraction features, you need to install the `@syncfusion/ej2-pdf-data-extract` package as an add-on.
-Image extraction and image‑based redaction features are optimized for browser environments where visual rendering is available. These features rely on browser technologies such as DOM APIs, Canvas, and client‑side rendering, and therefore are not supported in pure Node.js server environments.
+## Create a Node.js Project
+
+Create a new project folder and initialize it with `npm init`. The project uses CommonJS (the default `npm init` setting), so `require` syntax is used in `server.js`.
+
+```bash
+mkdir pdf-node-app
+cd pdf-node-app
+npm init -y
+```
+
+After initialization, the project root (`pdf-node-app`) contains a `package.json` file. The final project structure is:
+
+```text
+pdf-node-app/
+├── public/
+│   └── index.html
+├── server.js
+└── package.json
+```
 
-## Dependencies
+## Install Dependencies
 
-The following list of dependencies are required to use the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) component in your application.
+Install the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) and Express. Express is required to host the HTTP endpoint that generates and serves the PDF.
 
 ```bash
-|-- @syncfusion/ej2-compression
-|-- @syncfusion/ej2-base
+npm install @syncfusion/ej2-pdf express --save
 ```
 
+N> For data extraction features, install the `@syncfusion/ej2-pdf-data-extract` package as an add-on.
+
+N> Image extraction and image-based redaction features are optimized for browser environments where visual rendering is available. These features rely on browser technologies such as DOM APIs, Canvas, and client-side rendering, and therefore are not supported in pure Node.js server environments.
+
+### Required Dependencies
+
+The following packages are required to use the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) in a Node.js application:
+
+- `@syncfusion/ej2-pdf` — the core JavaScript PDF Library
+- `@syncfusion/ej2-base` — base utilities used by the PDF Library
+- `@syncfusion/ej2-compression` — compression support used internally by the PDF Library
+- `express` — HTTP server used to expose the PDF generation endpoint
+
+## License Registration
+
+If you are using a commercial Syncfusion license, register the license key at application startup. Add the following line near the top of `server.js`, before any other Syncfusion imports.
+
+```javascript
+require('@syncfusion/ej2-base').registerLicense('YOUR_LICENSE_KEY');
+```
+
+Replace `YOUR_LICENSE_KEY` with the key from your Syncfusion account. For more information, see the [Syncfusion licensing documentation](https://help.syncfusion.com/document-processing/licensing/overview).

 ## Create a Node.js Server Application to Generate a PDF Document
 
-* Add a simple button to `index.html` and attach a click handler that uses the TypeScript PDF API to create a new PDF document.
+* Create a `public` folder inside the project root. The Express server uses `express.static('public')` to serve files from this folder.
+
+```bash
+mkdir public
+```
+
+* Add a simple button to `public/index.html` and attach a click handler that calls the PDF generation endpoint using the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library).

+### Code Explanation
+
+- `PdfDocument` — creates a new PDF document instance.
+- `addPage()` — appends a blank page and returns the page object.
+- `page.graphics` — exposes the `PdfGraphics` instance used to draw content.
+- `embedFont(family, size, style)` — embeds one of the standard PDF font families. Returns a `PdfFont` object.
+- `PdfFontStyle.regular` — selects the regular (non-bold, non-italic) style.
+- `new PdfBrush({ r, g, b })` — creates a solid color brush from an RGB object (each channel `0`-`255`).
+- `graphics.drawString(text, font, layoutRect, brush)` — draws the text inside the rectangle defined by `x`, `y`, `width`, and `height`.
+- `graphics.clientSize.width` — the writable width of the page in points.
+- `document.save()` — returns the PDF as a `Uint8Array`. In a browser build, `pdf.save('filename')` is a helper that triggers a client download; in Node, you receive the bytes and stream them yourself.
+- `document.destroy()` — releases native resources held by the document.
+- `Buffer.from(pdfBytes)` — copies the `Uint8Array` into a Node `Buffer` for the HTTP response.
+
+## Run the Application
 
-Run the following command to start the Node.js server:
+Run the following command from the project root to start the Node.js server:
 
 ```bash
 node server.js
 ```
 
-This command starts the server and allows you to generate and download the PDF file from the browser.
+The server listens on `http://localhost:3000`. Open this URL in a browser and click **Create PDF** to download the generated file as `Output.pdf`.
+
+N> If the port is already in use, stop the conflicting process or change `PORT` in `server.js` to an available port. The error `EADDRINUSE` indicates a port conflict.
+
+## Output
+
+Clicking **Create PDF** triggers the `fetch('/generate-pdf')` call. The server responds with the PDF bytes and the `Content-Disposition: attachment; filename=Output.pdf` header causes the browser to download the file as `Output.pdf`. The file contains a single page with the text "Hello from Frontend!" drawn at the top-left of the page.
+
+![Output PDF document](Getting_started_images/Output.png)
+
+N> The `Content-Disposition: inline` value can be used instead of `attachment` if you want the PDF to open in a browser tab rather than download.
+
+## Troubleshooting
+
+| Problem | Cause | Resolution |
+|---|---|---|
+| `Error: Cannot find module 'express'` | Express is not installed | Run `npm install express` |
+| `Error: Cannot find module '@syncfusion/ej2-pdf'` | The PDF package is not installed | Run `npm install @syncfusion/ej2-pdf` |
+| `EADDRINUSE` on port 3000 | Another process is using the port | Stop the process or change `PORT` in `server.js` |
+| `require is not defined` | `package.json` has `"type": "module"` | Remove `"type": "module"` or convert `server.js` to ESM (`import` syntax) |
+| PDF opens as a blank file | The server returned an error payload | Check the terminal output and confirm `document.save()` runs without throwing |
+| Browser blocks the download due to CORS | Frontend and backend are on different origins | Install the `cors` package and add `app.use(cors())` to `server.js` |
+| `Output.pdf` does not download | The response headers are missing or incorrect | Confirm `Content-Type` is `application/pdf` and `Content-Disposition` includes `attachment; filename=Output.pdf` |
 
-By executing the program, you will get the PDF document as follows.

-## Installing JavaScript PDF package
+## Prerequisites
 
-All Syncfusion JS 2 packages are published in `npmjs.com` registry.
+Before you begin, make sure you have the following installed:
+
+- Node.js 18 or later.
+- npm 9 or later, or Yarn 1.22 or later.
+- React 18 or later.
+- Visual Studio Code, Code Studio, or another code editor.
+- A supported browser such as the latest versions of Microsoft Edge, Google Chrome, or Mozilla Firefox.
+
+To verify your Node.js and npm versions, run:
+
+```bash
+node --version
+npm --version
+```
+
+## Create a React Project
+
+This guide uses [Vite](https://vitejs.dev/) to scaffold the React project. Run the following command in a terminal:
+
+```bash
+npm create vite@latest my-pdf-app -- --template react
+cd my-pdf-app
+```
+
+After the project is created, install its dependencies:
+
+```bash
+npm install
+```
+
+## Install the JavaScript PDF Library
+
+All Syncfusion<sup>&reg;</sup> JS 2 packages are published in the `npmjs.com` registry. The `npm install` command below resolves `@syncfusion/ej2-pdf` to the latest stable version compatible with React 18 or later.
 
 * To install the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library), use the following command.
 
 ```bash
 npm install @syncfusion/ej2-pdf --save
 ```
-N> For image and data extraction features, you need to install the `@syncfusion/ej2-pdf-data-extract` package as an add-on.
-* Copy the `ej2-pdf-lib` folder from the @syncfusion/ej2-pdf-data-extract package into your project's **public, dist, or assets** directory (where your static files are served).
-* Make sure the `ej2-pdf-lib` folder exists in your final build output if you need to extract images or data from PDF files.
-* Ensure your server serves .wasm files with the **Content-Type: application/wasm** MIME type.
-* This setup is not required for **basic PDF creation**.
 
-**Create a PDF document**: Add the script in `App.jsx` by creating a button and attaching a click event that uses the JavaScript PDF API to generate a PDF document.
+N> For image and data extraction features, install the `@syncfusion/ej2-pdf-data-extract` package as an add-on. Note the following:
+- Copy the `ej2-pdf-lib` folder from the `@syncfusion/ej2-pdf-data-extract` package into your project's `public/`, `dist/`, or `assets/` directory (wherever your static files are served).
+- Make sure the `ej2-pdf-lib` folder exists in your final build output if you need to extract images or data from PDF files.
+- Ensure your server serves `.wasm` files with the **Content-Type: application/wasm** MIME type. Vite's development server already handles this; configure production servers manually.
+- This setup is not required for **basic PDF creation**.
+
+### Transitive Dependencies
+
+The following packages are included automatically by `@syncfusion/ej2-pdf` and do not need to be installed separately:
+
+- `@syncfusion/ej2-base` — common utilities used by the library.
+- `@syncfusion/ej2-compression` — compression support used by PDF features.
+
+## License Registration
+
+If your project requires a Syncfusion license, register the license key before using the PDF API. Add the following code at the top of `App.jsx`:
+
+```jsx
+import { registerLicense } from '@syncfusion/ej2-base';
+
+registerLicense('YOUR_LICENSE_KEY');
+```
+
+Replace `YOUR_LICENSE_KEY` with the key from your Syncfusion account. For more information, see the [Syncfusion licensing documentation](https://help.syncfusion.com/document-processing/licensing/overview).
+
+## Create a PDF Document
+
+Replace the contents of `App.jsx` with the following code. The file imports the PDF classes as named exports from `@syncfusion/ej2-pdf` and creates a one-page PDF with a click handler.

If you prefer the UMD-style global, load `ej2.min.js` from the Syncfusion CDN in `index.html` instead of importing the npm package.
 
-Now run the `npm run dev` command in the console to start the development server. This command compiles your code and serves the application locally, opening it in the browser.
+## Code Explanation
 
-```
+- `registerLicense(key)` — registers the Syncfusion license key at application startup. Required for commercial usage.
+- `PdfDocument` — creates a new PDF document instance.
+- `addPage()` — appends a blank page to the document and returns the `PdfPage` object.
+- `page.graphics` — returns the `PdfGraphics` drawing surface for the page.
+- `embedFont(family, size, style)` — embeds one of the standard PDF font families (here, Helvetica 36pt regular) and returns a `PdfFont` object.

 ```
-By executing the program, you will get the PDF document as follows.
+
+Vite serves the application at `http://localhost:5173`. Open this URL in a browser and click **Create PDF document** to download the generated file as `Output.pdf`.

+The generated PDF contains a single page with the text "Hello World!!!" drawn at the top-left.
 
 ![Output PDF document](Getting_started_images/Output.png)
+
+N> If you used Create-React-App instead of Vite, the run command is `npm start` and the default URL is `http://localhost:3000`.
+
+## Troubleshooting
+
+| Problem | Cause | Resolution |
+|---|---|---|
+| `ReferenceError: ej is not defined` | The code uses the global `ej.pdf` namespace but the npm package does not expose it | Switch to named imports: `import { PdfDocument, ... } from '@syncfusion/ej2-pdf'` |
+| `SyntaxError: Unexpected token ':'` in `App.jsx` | TypeScript type annotations were left in a `.jsx` file | Remove the `: ej.pdf.PdfType` annotations, or rename `App.jsx` to `App.tsx` and add TypeScript |
+| `Error: Cannot find module '@syncfusion/ej2-pdf'` | The package is not installed | Run `npm install @syncfusion/ej2-pdf --save` |
+| Button click does nothing | The click handler is not wired | Confirm the button uses `onClick={createPdf}` and that `createPdf` is defined in the same component |
+| `WASM` 404 or MIME type error | The `ej2-pdf-lib` folder is missing or not served with the right MIME type | Copy the `ej2-pdf-lib` folder from the `@syncfusion/ej2-pdf-data-extract` package into `public/` and confirm the server serves `.wasm` as `application/wasm` |
+| `Output.pdf` does not download | The browser blocks the download | Check the browser's download settings and the downloads folder |
+| `registerLicense` warning at runtime | The license key is missing or invalid | Confirm the key is set in `App.jsx` and is the correct key for your Syncfusion account |
+| Vite dev server fails to start | Port `5173` is in use | Stop the conflicting process or change the port in `vite.config.js` |

+This guide explains how to integrate the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) into a TypeScript application that runs in the browser. The generated PDF is downloaded directly from the browser; no server-side PDF rendering is required.
 
-## Installing the Syncfusion TypeScript PDF package
+## Prerequisites
 
-All Syncfusion JS 2 packages are published in `npmjs.com` registry.
+Before you begin, make sure you have the following installed:
+
+- Node.js 18 or later.
+- npm 9 or later, or Yarn 1.22 or later.
+- TypeScript 4.5 or later.
+- Code Studio, Visual Studio Code, or another code editor.
+- A browser-based bundler or dev server.
+
+To verify your Node.js and npm versions, run:
+
+```bash
+node --version
+npm --version
+```
+
+## Project Setup
+
+Create a new project folder and initialize it:
+
+```bash
+mkdir pdf-typescript-app
+cd pdf-typescript-app
+npm init -y
+```
+
+Install TypeScript and the Vite dev server as development dependencies:
+
+```bash
+npm install typescript vite --save-dev
+```
+
+Initialize the TypeScript configuration:
+
+```bash
+npx tsc --init
+```
+
+The following minimal configuration is sufficient for this guide:
+
+```json
+{
+  "compilerOptions": {
+    "target": "ES2020",
+    "module": "ESNext",
+    "lib": ["DOM", "ES2020"],
+    "strict": true,
+    "moduleResolution": "bundler"
+  }
+}
+```
+
+N> The `outDir` setting is ignored by Vite; the bundled output is emitted to `dist/` automatically.
+
+## Configure the Start Script
+
+Add a `start` script to `package.json` so you can launch the Vite dev server with `npm start`:
+
+```json
+{
+  "scripts": {
+    "start": "vite",
+    "build": "vite build",
+    "preview": "vite preview"
+  }
+}
+```
+
+## Install the JavaScript PDF Library
+
+All Syncfusion<sup>&reg;</sup> JS 2 packages are published in the `npmjs.com` registry. The `npm install` command below resolves `@syncfusion/ej2-pdf` to the latest stable version compatible with TypeScript 4.5 or later.
 
 * To install the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library), use the following command.
 
 ```bash
 npm install @syncfusion/ej2-pdf --save
 ```
-N> For image and data extraction features, you need to install the `@syncfusion/ej2-pdf-data-extract` package as an add-on.
-Ensure that your application includes an `ej2-pdf-lib` folder within a publicly accessible static directory (such as wwwroot, public, or dist). This folder must contain the required `.js` and `.wasm` files needed for image and data extraction. This setup is not required for **basic PDF creation**.
 
-## Dependencies
+N> For image and data extraction features, install the `@syncfusion/ej2-pdf-data-extract` package as an add-on. Note the following:
+- Ensure that your application includes an `ej2-pdf-lib` folder within a publicly accessible static directory (such as `public/`, `dist/`, or `wwwroot/`).
+- This folder must contain the required `.js` and `.wasm` files needed for image and data extraction.
+- This setup is not required for **basic PDF creation**.
 
-The following list of dependencies are required to use the [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) component in your application.
+### Transitive Dependencies
 
-```bash
-|-- @syncfusion/ej2-compression
-|-- @syncfusion/ej2-base
+The following packages are included automatically by `@syncfusion/ej2-pdf` and do not need to be installed separately:
+
+- `@syncfusion/ej2-base` — common utilities used by the library.
+- `@syncfusion/ej2-compression` — compression support used by PDF features.
+
+## License Registration
+
+If your project requires a Syncfusion license, register the license key before using the PDF API. Add the following code at the top of your entry point (e.g., `index.ts`):
+
+```ts
+import { registerLicense } from '@syncfusion/ej2-base';
+
+registerLicense('YOUR_LICENSE_KEY');
 ```
 
+Replace `YOUR_LICENSE_KEY` with the key from your Syncfusion account. For more information, see the [Syncfusion licensing documentation](https://help.syncfusion.com/document-processing/licensing/overview).
+
 ## Create a PDF document using TypeScript
 
-* Add a simple button to `index.html` and attach a click handler that uses the TypeScript PDF API to create a new PDF document.
+This sample is intended for **browser-based** TypeScript applications. It is not designed for server-side rendering or Node.js-only execution.
+
+* Add a simple button to `index.html` and a `<script type="module">` tag that loads `index.ts`. The button must exist before the click handler in `index.ts` runs.

+| `TS2304: Cannot find name 'PdfDocument'` (or similar) | The import line is missing | Confirm the `import` block at the top of `index.ts` is present |
+| Button click does nothing | The button ID does not match | Confirm the button's `id` is `normalButton` |
+| `Failed to resolve import "@syncfusion/ej2-pdf"` | The bundler cannot resolve the package | Confirm `node_modules/` exists and that you ran `npm install` |
+| `ReferenceError: document is not defined` | The code ran in a Node-only context (e.g., SSR) | This sample is browser-only; run it in a browser via `npm start` |
+| `Cannot GET /` | The dev server is not running | Run `npm start` and wait for "Local: http://localhost:5173/" |
+| PDF does not download | The browser blocks the download | Check the browser's download settings and downloads folder |
+| `registerLicense` warning at runtime | The license key is missing or invalid | Confirm the key is set in `index.ts` and is the correct key for your Syncfusion account |

-## Run the project
+N> This sample uses **named imports** from the npm package (`import { PdfDocument, ... } from '@syncfusion/ej2-pdf'`). The npm package does not expose a global `ej` namespace; using `ej.pdf.PdfDocument` without an import will throw `ReferenceError: ej is not defined` in a Vite or Vue CLI build. If you prefer the UMD-style global, load `ej2.min.js` from the Syncfusion CDN in `index.html` (or `public/index.html`) instead of importing the npm package.
+
+N> A click handler is used in this example, so no additional setup is required. The PDF classes load when the import runs at module evaluation time, which happens before any user interaction.
 
-To run the project, use the following command:

+
+## Troubleshooting
+
+| Problem | Cause | Resolution |
+|---|---|---|
+| `ReferenceError: ej is not defined` | The code uses the global `ej.pdf` namespace but the npm package does not expose it | Switch to named imports: `import { PdfDocument, ... } from '@syncfusion/ej2-pdf'` |
+| `SyntaxError: Unexpected token ':'` in `App.vue` | TypeScript type annotations were left in a plain `<script>` block | Remove the `: ej.pdf.PdfType` annotations, or add `lang="ts"` to the `<script>` tag and configure TypeScript in the project |
+| `Error: Cannot find module '@syncfusion/ej2-pdf'` | The package is not installed | Run `npm install @syncfusion/ej2-pdf --save` |
+| Button click does nothing | The click handler is not wired | Confirm the button uses `@click="createPdf"` and that `createPdf` is defined in the `methods` block |
+| `WASM` 404 or MIME type error | The `ej2-pdf-lib` folder is missing or not served with the right MIME type | Copy the `ej2-pdf-lib` folder from the `@syncfusion/ej2-pdf-data-extract` package into `public/` and confirm the server serves `.wasm` as `application/wasm` |
+| `Output.pdf` does not download | The browser blocks the download | Check the browser's download settings and the downloads folder |
+| `registerLicense` warning at runtime | The license key is missing or invalid | Confirm the key is set in `App.vue` and is the correct key for your Syncfusion account |
+| Port already in use (`5173` or `8080`) | Another process is using the port | Stop the conflicting process or change the port in `vite.config.js` / `vue.config.js` |
+| `npm install` warns about deprecated packages on Vue 2 | Vue 2 and `@vue/cli` are in maintenance / EOL | Migrate to Vue 3 using `npm create vue@latest` |
