$ yarn reset
$ yarn start

$ yarn deploy

To create a migration:

$ yarn db-migrate create foobar-baz  # creates migrations/20180411004626-foobar-baz.js

Run the migrations:

$ yarn migrate

Reset migrations (tear down all and re-run):

$ yarn reset

To start the production server, you should use this command:

$ NODE_ENV=production pm2 start /path/to/deploy/dir/current/src/index.js

If that is the command used to start the process, the yarn deploy will work correctly, since all it does is execute pm2 restart all, thus restarting the process originally started.

To troubleshoot and log out stuff from production, try:

$ pm2 delete all
$ NODE_ENV=production nodemon /path/to/deploy/dir/current/src/index.js
