Next, please visit this guide to learn how to obtain API credentials (Client ID + Client Secret). Again, it’s super simple and you can generate API credentials without any hassle.
Merge JPG Files in Node.js Programmatically
Now, we are all ready to start writing code snippet to merge JPG files in Node.js. For this purpose, we already have uploaded two different JPG images to our API Cloud dashboard. You can upload the files manually or programmatically by calling the UploadFile method.
The following are the steps to combine JPG files programmatically:
- Require the groupdocs-merger-cloud module in your project.
- Get your API credentials from API Cloud Dashboard.
- Invoke the fromKeys method of the DocumentApi class and pass the API credentials.
- Instantiate an object of the JoinItem class that describes the document for the join operation.
- Instantiate an instance of the FileInfo class.
- Set the file path of the source JPG files by invoking the filePath property.
- Create an object of the JoinOptions class.
- Invoke the JoinItems property to assign the source document array.
- Set the output path for generated merged JPG images.
- Initialize an object of the JoinRequest class and pass it into the join method to merge JPG files.
Copy & paste the following code snippet to merge JPG files:
Once you run the server, you will find a new merged jpg file in the “Output” folder in the API Cloud dashboard, you can see the output file in the image below:
Here you can download the generated JPG file manually or programmatically by calling this DownloadFile method.
