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

WARNING: Doesn’t work for Ambari or Mpack updates

Here are the instructions for "quickly" getting middleware and backend updates without a full-dev rebuild:

1. Run mvn clean install -Dskip from the root of your local metron project
2. From metron-deployment/development/centos6, run vagrant scp ../../../metron-interface/metron-rest/target/metron-rest*.jar /tmp
3. Log into vagrant by navigating into metron-deployment/development/centos6 and running vagrant ssh
4. While ssh'd inside the vagrant machine, run sudo cp /tmp/metron-rest*.jar /usr/metron/$METRON_VERSION/lib
5. Open a browser, visit Ambari (http://node1:8080) and reset (or start) METRON REST

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

The Beginning

Yes...it's true...redux is smart....smarter than you even know. It really does want to help you. It strives to be sane and easy to reason about. With that being said, redux gives you optimizations for free that you probably were completely unaware of.

connect()

connect is the most important thing in redux land IMO. This is where you tie the knot between redux and your underlying components. You usually take state and propogate it down your component hiearchy in the form of props. From there, presentational

gaearon

// connect() is a function that injects Redux-related props into your component.
// You can inject data and callbacks that change that data by dispatching actions.
function connect(mapStateToProps, mapDispatchToProps) {
  // It lets us inject component as the last step so people can use it as a decorator.
  // Generally you don't need to worry about it.
  return function (WrappedComponent) {
    // It returns a component
    return class extends React.Component {
      render() {
        return (

###Redux Egghead Video Notes###

####Introduction:#### Managing state in an application is critical, and is often done haphazardly. Redux provides a state container for JavaScript applications that will help your applications behave consistently.

Redux is an evolution of the ideas presented by Facebook's Flux, avoiding the complexity found in Flux by looking to how applications are built with the Elm language.

####1st principle of Redux:#### Everything that changes in your application including the data and ui options is contained in a single object called the state tree
