Redux WebSocket Middleware: Example

This Gist provides some code examples of how to implement WebSocket stream handling using a Redux middleware. Please be aware that this is only provided as an example and that critical things like exception handling have not been implemented.

A more complete version has been packaged, tested, and is available on GitHub as redux-websocket. This library has also been published to npm at @giantmachines/redux-websocket.

Middleware

This module represents the foundation of the middleware and implements the ideas presented above. The exported function is used during the creation of the Redux store (see the following snippet).

Setting up Vim as your Go IDE

Intro

I've been wanting to do a serious project in Go. One thing holding me back has been a my working environment. As a huge PyCharm user, I was hoping the Go IDE plugin for IntelliJ IDEA would fit my needs. However, it never felt quite right. After a previous experiment a few years ago using Vim, I knew how powerful it could be if I put in the time to make it so. Luckily there are plugins for almost anything you need to do with Go or what you would expect form and IDE. While this is no where near comprehensive, it will get you writing code, building and testing with the power you would expect from Vim.

Getting Started

I'm assuming you're coming with a clean slate. For me this was OSX so I used MacVim. There is nothing in my config files that assumes this is the case.

# first check to see if mongo service is running. you can't delete any files until the service stops so perform a quick check.
launchctl list | grep mongo
  # NOTE: the pipe | symbol means the commands on the right performs on the output from the left
  # grep is a string search utility. `grep mongo` means search for the substring mongo
 
# use the unload command to end the mongo service. this is required to 'unlock' before removing the service.
#    first look for the file to delete
