Install

npm install grunt-foreman --save-dev

Usage

Use as such, if your procfile is called Procfile and you don't need anything else:

grunt.loadNpmTasks("grunt-foreman");

grunt.registerTask("serve", "foreman");

Optionally, you can add configuration (by target, 'dev' as default) for one, many or any of:

• one or more env files
• a Procfile
• the port to use

grunt.initConfig({
    foreman: {
        dev: {
            env: [ "development.env", "application.env" ],
            procfile: "Procfile.dev",
            port: 7000
        } //,
    //  production: {
    //      ...
    //  }
    }        
});

Enjoy!
