Installation Guide

Deploy on Linux using PM2:

Production mode:

$ pm2 start production.json
$ pm2 stop production.json
$ pm2 delete production.json
$ pm2 restart production.json

Development mode

$ pm2 start development.json
$ pm2 stop development.json
$ pm2 delete development.json
$ pm2 restart development.json

Test with NODE_ENVIRONMENT

Windows:

set NODE_ENV=production && node app.js

Linux:

NODE_ENV=production node app.js

#Before You Deploy

Before you launch any web application, you should ask yourself a few questions:

  • What is your expected traffic?
  • Are you contractually required to meet any uptime guarantees, e.g. a Service Level Agreement (SLA)?
  • What sorts of front-end apps will be "hitting" your infrastructure?
    • Android apps
    • iOS apps
    • desktop web browsers
    • mobile web browsers (tablets, phones, iPad minis?)
    • tvs, watches, toasters..?
  • And what kinds of things will they be requesting?
    • JSON?
    • HTML?
    • XML?
  • Will you be taking advantage of realtime pubsub features with Socket.io?
    • e.g. chat, realtime analytics, in-app notifications/messages
  • How are you tracking crashes and errors?
    • Take a look at Sails' log config

Deploying On a Single Server

Node.js is pretty darn fast. For many apps, one server is enough to handle the expected traffic-- at least at first.

Configure

  • All your production environment settings are stored in config/env/production.js
  • Configure your app to run on port 80 (if not behind a proxy like nginx). If you're using nginx, be sure to configure it to relay websockets to your app. You can find guidance here in nginx docs WebSocket proxying.
  • Configure the 'production' environment so that all of your css/js gets bundled up, and the internal servers are switched into the appropriate environment (requires linker)
  • Make sure your database is set-up on the production server. This is especially important if you are using a relational database such as MySQL, because sails sets all your models to migrate:safe when run in production, which means no auto-migrations are run on starting up the app. You can set your database up the following way:
    • Create the database on the server and then run your sails app with migrate:alter locally, but configured to use the production server as your db. This will automatically set things up.
    • In case you can't connect to the server remotely, you'll simply dump your local schema and import it into the database server.
  • Enable CSRF protection for your POST, PUT, and DELETE requests
  • Enable SSL
  • IF YOU'RE USING SOCKETS:
    • Configure config/sockets.js to use socket.io's recommended production settings here
      • e.g. enable the flashsocket transport

Deploy

In production, instead of sails lift, you'll want to use forever or PM2 to make sure your app will keep running, even if it crashes.

  • Install forever: sudo npm install -g forever
  • Or install PM2: sudo npm install pm2 -g --unsafe-perm
  • From your app directory, start the server either with forever start app.js --prod or pm2 start app.js -x -- --prod
    • This is the same thing as using sails lift --prod, but if the server crashes, it will be automatically restarted.
