In this article, we delve into how you can effectively use the using Node JS. ApyHub Video Watermarking API To add an image watermark to a video using Node.js, follow the step-by-step tutorial below: 1. Install the required libraries: To install all the required dependencies, run this command on the terminal of your project folder. npm install axios fs Once we run `npm install` in the terminal, the command triggers the installation of the specified dependencies listed in the project's `package.json` file. The following dependencies are commonly installed. : A popular HTTP client library for making HTTP requests in Node.js. It simplifies the process of sending HTTP requests and handling responses. In this case, axios is used to make a POST request to the Video Watermarking API, sending the video URL and watermark image URL. axios : A built-in module in Node.js that provides functionalities for working with the file system. In this context, fs is used to create a write stream and save the watermarked video file. The `createWriteStream` function allows you to write the response data from the API request directly to a file on the local file system. fs (File System) 2. Create a new file: The next step is to create a new file; for example, create a file `videoWatermark.js` and add the following code to import the required libraries we installed.: const axios = require('axios'); const fs = require('fs'); 3. Define a function to add the image watermark to the video: This function encapsulates the logic for making the API request to add the image watermark to the video, saving the watermarked video to a file using a write stream, and handling potential errors during the process. We will need `apytoken` which you can find from [ApyHub Video Watermarking API documentation](https://apyhub.com/utility/watermark-video). async function addWatermark(videoURL, watermarkImageURL, outputFileName) { const apiURL= 'https://api.apyhub.com/generate/video/watermark/url/file?output=${outputFileName}.mp4' const requestData = { video_url: videoURL, watermark_image_url: watermarkImageURL }; try { const response = await axios.post(apiURL, requestData, { headers: { 'Content-Type': 'application/json', 'apy-token': '**** ADD-YOUR-SECRET-APY-TOKEN-HERE ****' }, responseType: 'stream' // To get the response as a stream }) const writeStream = fs.createWriteStream('${outputFileName}.mp4'); // Path where the watermarked video will be saved response.data.pipe(writeStream); return new Promise((resolve, reject) => { writeStream.on('finish', resolve); // Resolve the promise when writing is finished writeStream.on('error', reject);  // Reject the promise if an error occurs }); } catch (error) { throw new Error('Failed to add watermark. ' + error.response.data.error.message); } } 4. Invoke the addWatermark function After invoking the function, pass the video URL and the watermark image URL as arguments. This function sends a request to the Video Watermarking API, which adds the watermark to the video and streams the watermarked video as a response. The response is then saved to a file using a write stream. addWatermark const videoURL = '***** PROVIDE THE URL OF VIDEO *****'; const watermarkImageURL = '***** PROVIDE THE URL OF IMAGE *****'; const outputFilename = '***** PROVIDE THE OUTPUT FILE NAME *****'; addWatermark(videoURL, watermarkImageURL, outputFilename) .then(() => { console.log('Watermark added successfully!'); })     .catch((error) => { console.error('Error:', error.message); }); 5. Save file and execute script Save the file and open your terminal, navigate to the project directory, and run the following command to execute the script: node videoWatermark.js 6. Send a request to the API The script will send a request to the API, download the watermarked video, and save it as provided file name in your project directory. That's it! You have successfully added an image watermark to a video using Node.js. ${outputFileName}.mp4 You can use the ApyHub video watermarking tool to effectively watermark your video content, whether in the form of files or URLs.
