Grunt watch: only upload files that have changed

I was able to set up a Grunt task to SFTP files up to my dev server using grunt-ssh:

sftp: {
    dev: {
        files: {
            './': ['**','!{node_modules,artifacts,sql,logs}/**'],
        },
        options: {
            path: '/path/to/project',
            privateKey: grunt.file.read(process.env.HOME+'/.ssh/id_rsa'),
            host: '111.111.111.111',
            port: 22,
            username: 'marksthebest',
        }
    }
},

But this uploads everything when I run it. There are thousands of files. I don't have time to wait for them to upload one-by-one every time I modify a file.

How can I set up a watch to upload only the files I've changed, as soon as I've changed them?

(For the curious, the server is a VM on the local network. It runs on a different OS and the setup is more similar to production than my local machine. Uploads should be lightning quick if I can get this working correctly)

What you need is grunt-newer, a task designed especially to update the configuration of any task depending on what file just changed, then run it. An example configuration could look like the following:

watch: {
  all: {
    files: ['**','!{node_modules,artifacts,sql,logs}/**'],
    tasks: ['newer:sftp:dev']
  }
}
