How to use this gist

You've got two main options:

Iheanyi,

I realize your app may not be ruby-based, but here's how I've worked with this dilemma in mind in our app. To start, yes, we don't necessarily support custom CSS, but I do have a database field I (as admin) can add custom CSS to a customer's account template (in the case they have "premium support" or something). Our publicly customizable style settings are key:value based and stored as a JSON object in psql as you suggested might be an option. Here's how I make it less unweildy:

Field in the database:

t.json :settings

Ctags with Ruby/Rails

We can ctags lots of programming languages. Here is how to do it for ruby/rails. I really like how RubyMine jumps to the source code (either withing project score or to the gem source). This is really useful for reading source code for those classes, methods, modules etc. But Now that I use vim as My IDE/Editor I really like that functionality to happen in my vim editor. And I found ctags as the solution.

	function dl
	set prev (pwd)
	set songs "$HOME/Documents/Music/Songs"
	cd $songs
	youtube-dl -x --audio-format \"wav\" $argv
	cd $prev
	end

	func CreatePDFFromHTML(inputHTML []byte) ([]byte, error) {
	dirName, err := ioutil.TempDir("", "pdf-generator")
	if err != nil {
	return nil, err
	}

	// remove this and log the dirName if you need to debug the HTML
	defer os.RemoveAll(dirName)
	// log.Println(dirName)

	// Installation:
	// yarn add -D @codemod/cli @babel/plugin-syntax-jsx @babel/generator

	import jsx from '@babel/plugin-syntax-jsx';
	import generate from '@babel/generator';
