Web Interaction Start (Labs)

This node opens a browser session for the web interaction nodes and outputs the session connection for downstream steps.

You can choose the browser, optionally provide a browser executable path, and control headless mode, window maximization, and custom command-line arguments where supported. KNIME proxy settings are applied when available, except Safari ignores them and Firefox does not support authenticated proxies.

Options

Browser Choice

Browser

The browser that will be remote-controlled by KNIME.

Available options:

Executable path

Path to the browser executable e.g. path/to/chrome/chrome.exe.

If not provided, the node will try to find the executable at its default location.

For Windows: Click on the windows logo on the task bar and search for <browser>.exe. Then copy its path.

For Apple: Use Finder to select e.g. Google Chrome.app and copy the path to the binary from the package content.

For Linux: Use 'which <browser>' in the terminal to locate the binary. The 'which' command will not find the binary if the browser was installed through snap or similar tool.

Browser Settings

Command line arguments

Not possible for Safari.

List of command line arguments executed at browser start. E.g. for Chrome : --disable-extensions --mute-audio

Use headless browser

Not possible for Safari.

A headless browser is a web browser without a graphical user interface. The browser might behave different to a regular browser due to detection by the web page provider. To prevent this use command line switches to change user agents.

Maximize window

Opens the browser in a maximized window.

It is recommended to start the browser with this flag in order to guarantee equal results when sharing a workflow.
