## Get Started

1. **Set Up Environment**: Ensure that [Node.js 20 LTS](https://nodejs.org/) is installed on your system.

2. **Get the Code**: Clone or download this repository.

   ```bash
   git clone git@github.com:groupdocs-viewer/GroupDocs.Viewer-for-Node.js-via-Java.git
   ```

3. **Navigate to the `Examples` Folder**

   ```bash
   cd ./GroupDocs.Viewer-for-Node.js-via-Java/Examples
   ```

4. **Install Package**: To install the package, run `npm install`. We typically keep the package up to date with the latest version. If you need to use a different package version, you can update the package.json file accordingly.

   Alternatively, you can download the `tgz` file from the official [GroupDocs Releases](https://releases.groupdocs.com/viewer/nodejs-java/#direct-download) website. To install the package manually, copy the tgz file to the `Examples` directory and run the following command:
   
   ```bash
   npm install ./groupdocs.viewer-*.tgz
   ```

5. **Configure License (Optional)**: If you have a license file, you can set the license path in the `run_all_examples.js` file. By default, GroupDocs.Viewer for Node.js via Java checks for the `GROUPDOCS_LICENSE_PATH` environment variable or looks for files with the `.lic` extension in the project's root directory. You can also [get a temporary license](https://purchase.groupdocs.com/temporary-license) to test all the features.

6. **Run the Examples**: To run all the examples, execute the following command:

   ```bash
   npm start
   ```

   You can also run individual examples by navigating to the folder containing the example script and running it. Output files are placed in the same folder as the script file.
