Some examples where we could use a browser automation API are: With browser automation, we can do most of the things we do manually with a web browser. We also have different elements inside a web page that we can interact with: dialogs, downloads, authentication forms, videos, etc. With a browser automation tool, we can simulate interactions using input devices (keyboard, mouse, etc.), or we can verify that visual elements are working and displayed correctly. Its purpose is to achieve efficiency and speed at a certain level that wouldn't be possible if we rely on human interaction. 'Browser automation' is the action of automating the usage of a web browser. In this article, we will see how to implement automatic workflows interacting with a web browser instance. One example of this is the dynamic generation of files and images. We get consistent results over iterations.īesides the benefits that automation brings us, there are some scenarios that couldn't be achieved if we don't execute an automatic process.Some of the reasons why we should try to automate our workflows are: Just call the API and pass in the PDF URLs to join them into a single file and receive the generated result via webhook or via polling.One of the goals every developer has is to automate as many actions and tasks as possible. You can use the API to join your PDFs that are generated using Puppeteer too if they are hosted on a server. Bannerbear has an API to join PDF files when you generate PDFs from templates using Bannerbear’s PDF generation API. If you have multiple PDFs and want to join them into a single PDF, here’s an easy method to do so. to generate PDFs, so feel free to play around with the code.

You can also modify the code to pass in different arguments to the function, eg. Margin: ,ġ-Run node index.js or node index.js url to convert the HTML content of a web page using its URL into a PDF.Ģ-Run node index.js file to convert the content of an HTML file into a PDF.
