The apt-get version of node is incredibly old, and installing a new copy is a bit of a runaround.

So here's how you can use NVM to quickly get a fresh copy of Node on your new Bash on Windows install

$ touch ~/.bashrc
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
// restart bash
$ nvm install --lts

The Complete Guide to Nested Forms in Phoenix

I recently spent some time dealing with nested forms in Phoenix. Nested forms are great when you want to create multiple database records in a single transaction and associate them with each other. I am new to Phoenix and really struggled to find any resources that helped me with my specific problem. I decided to document what I learned in the process in hopes of helping others that are new to Elixir and Phoenix.

Here is my attempt at a one stop shop to learn everything you will need to know about nested forms. If you would like to view the GitHub repo you can check it out here.

Thanks to Heartbeat and Jose for excellent blog posts on nested forms. Also shoutout to Josh for showing me some examples at Ruby

What's this?

Instructions to obtain ZSH on a windows environment, without the input funny business presented by some other attempted solutions.

The final result is ZSH running on a mintty terminal, emulated by cygwin, and being handled by the popular cmder.

Why is this here?

For the benefit of myself and others. I've already followed these instructions twice. It took me hours to figure all this out, maybe someone else can save a few.

What exactly is covered?

• Installing and setting up cmder

Here's how to make jQuery DataTables work with npm and webpack. This is the simplest way I found to do it.
See the previous revision of this gist for a way to do it with forcing AMD to be disabled if you need that.

Install DT core: npm install datatables.net
Install a DT style: npm install datatables.net-dt

Then to initialize DT in your app, do this in your main entry point:

// you can use import or require
import dt from 'datatables.net';
