npm run webpack-dev-server -- --open-page example.html#page1
Some applications may consist of multiple pages. During development it may
be useful to directly open a particular page. The page to open may be specified
as the argument to the open-page
option.
The script should open http://localhost:8080/example.html#page1
in your
default browser. You should see the text on the page itself change to read Success!
