Serverless plugin author's cheat sheet

This cheat sheet provides a detailed overview of the exposed lifecycle events and available commands (and entrypoints) of the Serverless framework, that can be hooked by plugins (internal and external ones). The document is structured by the commands invoked by the user.

Lifecycle events are shown as the globally available outer events (all providers) and sub lifecycle events that are provider specific in the called order. Currently only the AWS provider is shown. If you have information about the other provider,

provider:

  runtime: nodejs6.10

functions:

    handler: handler.myfunc

Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user

# Don't add passphrase
ssh-keygen -t rsa -b 4096 -m PEM -f jwt.key

openssl rsa -in jwt.key -pubout -outform PEM -out jwt.pub

# remove the jwt.key.pub you don't need it
rm -rf jwt.key.pub

cat jwt.key
cat jwt.pub

NodeJS require concept for local modules

The problem

As your NodeJS app grows bigger, the file structure tends to go 3 to even 5 layers deep. The problem now is as you require local modules you created, you'll have to write them in this way:

const myModule = require('../../../my/module');

Looping through elements

http://jsben.ch/UgRvN

• Accesses length property every loop.
• Accesses length property only once and saves it into a constant.
• Uses forEach method.

How to follow this guide

• Don't type or run anything until I told you so.
• This guide uses linux commands. For windows users, you can use win-bash
  • https://sourceforge.net/projects/win-bash/files/shell-complete/latest/
  • http://win-bash.sourceforge.net/

The problem

I have one computer and two different github accounts. One is for work, the other is for my personal stuff. I can't use the same ssh key twice, so I have to use different ssh key for each of my accounts. How do I do that? How do I switch between these ssh keys?

Fun with strings!

Longest Common Substring & longest consecutive substring

The idea here is to get the longest common substring of two or more strings. For example, given the strings Heeeeeeeelllllloooo and teeeeeeeestoooo, it will return the string eeeeeeee, because it is the longest common string of the two.

• See Javascript implementation.
