This document provides a summary of tools and best practices for developing Node.js applications. It recommends using process managers like PM2 or Forever to prevent apps from crashing. It also suggests tools for debugging like node-inspector. The document then discusses concepts like statelessness, Redis for state, popular frameworks like Express and Hapi, and testing. It emphasizes best practices like horizontal scalability, avoiding recreating existing tools, early testing, and using streams.

7. LET YOUR PROCESS
CRASH
$
npm
install
pm2@latest
-­‐g
pm2
Modern CLI process manager for Node apps with a
builtin load-balancer
$
pm2
start
app.js
$
npm
install
forever
-­‐g
forever
A simple CLI tool for ensuring that a given node
script runs continuously (i.e. forever)
$
forever
start
app.js

8. FIND ISSUES

12. npm versioning
"dependencies":
{
"express":
"*"
}
No
Asterisks
Please for the love don’t use asterisks.
Use proper versioning.
"dependencies":
{
"express":
"4.0"
}

13. LESSONS LEARNED
stateless
Keep your application as stateless as possible
redis
Great tool if you need to keep state

15. API
The natural born use case for Node.js
express
Fast, unopinionated, minimalist web framework
hapi
HTTP Server framework - from the minds at Walmart
restify
REST framework

16. FINAL THOUGHTS
horizontal
scalability
Be stateless or have a thought out solution
don’t
reinvent
the
wheel
unless you want to, npm is there for a reason
start
testing
early
Pick a testing framework and start writing tests
streams
Learn to use them - streams adventure
kiss
Keep it simple stupid
