find_chrome: Find path to Chrome or Chromium browser

In chromote: Headless Chrome Web Browser Interface

Find path to Chrome or Chromium browser

Description

chromote requires a Chrome- or Chromium-based browser with support for the Chrome DevTools Protocol. There are many such browser variants, including Google Chrome, Chromium, Microsoft Edge and others.

If you want chromote to use a specific browser, set the CHROMOTE_CHROME environment variable to the full path to the browser's executable. Note that when CHROMOTE_CHROME is set, chromote will use the value without any additional checks. On Mac, for example, one could use Microsoft Edge by setting CHROMOTE_CHROME with the following:

Sys.setenv(
  CHROMOTE_CHROME = "/Applications/Microsoft Edge.app/Contents/MacOS/Microsoft Edge"
)

When CHROMOTE_CHROME is not set, find_chrome() will perform a limited search to find a reasonable executable. On Windows, find_chrome() consults the registry to find chrome.exe. On Mac, it looks for ⁠Google Chrome⁠ in the ⁠/Applications⁠ folder (or tries the same checks as on Linux). On Linux, it searches for several common executable names.

Usage

find_chrome()

Value

A character vector with the value of CHROMOTE_CHROME, or a path to the discovered Chrome executable. If no path to is found, find_chrome() returns NULL.

Examples

find_chrome()
