wkhtmltoimage is just a function, which you call with either a URL or an inline HTML string, and it returns a stream that you can read from or pipe to wherever you like (e.g. a file, or an HTTP response).
There are many options available to wkhtmltoimage. All of the command line options are supported as documented on the page linked to above. The options are camelCased instead-of-dashed as in the command line tool.
There is also an
output option that can be used to write the output directly to a filename, instead of returning a stream.
First, you need to install the wkhtmltoimage (included with wkhtmltopdf) command line tool on your system. The easiest way to do this is to download a prebuilt version for your system.
Then install the node module, use
npm install wkhtmltoimage
wkhtmltoimage is in your PATH when you're done installing. Alternatively, use .setCommand(path) to specify the binary path.
