Upgrade PostgreSQL 9.6.5 to 10.0 using Homebrew (macOS)
After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."
Database files have to be updated before starting the server, here are the steps that had to be followed:
# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install [email protected]
brew unlink [email protected]
brew link postgresql

Alternative to Higher-order Components

React now supports the use of ES6 classes as an alternative to React.createClass().

React's concept of Mixins, however, doesn't have a corollary when using ES6 classes. This left the community without an established pattern for code that both handles cross-cutting concerns and requires access to Component Life Cycle Methods.

In this gist, @sebmarkbage proposed an alternative pattern to React mixins: decorate components with a wrapping "higher order" component that handles whatever lifecycle methods it needs to and then invokes the wrapped component in its render() method, passing through props.

While a viable solution, this has a few drawbacks:

  1. There's no way for the child component to override functionality defined on the higher order component.

Pure Render Mixin in ES6
function pureRenderMixin(Component) {

return !shallowEqual(this.props, nextProps) ||
!shallowEqual(this.state, nextState);
}
return Component;
}
class MyComponent extends React.Component {}

Compilation of questions and answers about Relay from React.js Conf.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

##Step 1 - Homebrew The first thing to do, if you're on a Mac, is to install homebrew from http://mxcl.github.io/homebrew/

The command to type into terminal to install homebrew is:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
