package.json / scripts:

  "scripts": {     "debug": "node debug app.js",     "start": "sails lift --prod"   } 

config/env/production:

module.exports = {    models: {     connection: 'mongodbprod'   },    port: 80,    log: {      level: "silent"   }  }; 

any direction appreciated!

you can use specialized buildpack heroku runs grunt tasks on deployment, , turn off grunt in sails production environment. it's bit more work, can become necessary because heroku has own timeout can tripped grunt taking long crunch assets.

we've had success heroku-buildpack-nodejs-grunt. can follow instructions install on heroku app, copy task definition in tasks/register/prod.js include heroku:production task, e.g.:

module.exports = function (grunt) {    grunt.registertask('prod', [     'compileassets',     'concat',     'uglify',     'cssmin',     'sails-linker:prodjs',     'sails-linker:prodstyles',     'sails-linker:devtpl',     'sails-linker:prodjsjade',     'sails-linker:prodstylesjade',     'sails-linker:devtpljade'   ]);    grunt.registertask('heroku:production', [     'compileassets',     'concat',     'uglify',     'cssmin',     'sails-linker:prodjs',     'sails-linker:prodstyles',     'sails-linker:devtpl',     'sails-linker:prodjsjade',     'sails-linker:prodstylesjade',     'sails-linker:devtpljade'   ]);  }; 

then in app.js file, replace

sails.lift(rc('sails')); 

with:

var config = rc('sails'); if (process.env.node_env === 'production') {   config.hooks = config.hooks || {};   config.hooks.grunt = false; } // start server sails.lift(config);
