![]() 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.

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: Tells Puppeteer to not download during installation.Ĭan be overridden by PUPPETEER_SKIP_DOWNLOAD.ĭefines the directory to be used by Puppeteer for creating temporary files.One of the goals every developer has is to automate as many actions and tasks as possible. Tells Puppeteer to log at the given level. Specifies an executable path to be used in puppeteer.launch.Ĭan be overridden by PUPPETEER_EXECUTABLE_PATH.ĭefines experimental options for Puppeteer. Specifies the path for the downloads folder.Ĭan be overridden by PUPPETEER_DOWNLOAD_PATH. Specifies the URL prefix that is used to download the browser.Ĭan be overridden by PUPPETEER_DOWNLOAD_BASE_URL. Specifies which browser you'd like Puppeteer to use. Path.join(os.homedir(), '.cache', 'puppeteer') See puppeteer.launch on how executable path is inferred.ĭefines the directory to be used by Puppeteer for caching.Ĭan be overridden by PUPPETEER_CACHE_DIR. Specifies a certain version of the browser you'd like Puppeteer to use.Ĭan be overridden by PUPPETEER_BROWSER_REVISION.
