grunt this site can't be reached - gruntjs

Question

For some reason running grunt from the terminal doesn't work. When I run grunt dev and open http://localhost:8000/ it works, but when I just use grunt it says This site can’t be reached. localhost refused to connect.
Any ideas what I am missing?

Answer 1

Once you execute 'grunt', 'default' command will be executed.
In your case, only 'watch' task is executed.
grunt.registerTask('default', ['watch']);
If you want to reach 'localhost', you need to run 'connect' module.
'watch' task is just watching file changes. not launch web-server.
'connect' is for launching web-server.
Thanks.
