short tool for easily creating DOM elements and children (mini OG react :])

Create Element

A short (~50 lines of code) tool that you can use to easily create DOM elements and their children. Similar to the original React way of creating components :]

Simple Example

with config.children using just HTML template strings and a nested config object.

Initial HTML

View jquery-light.js
* 90% of JQuery
* @param {String} cssSelectorString: any valid css selector syntax
* @returns for ID selectors: Element
* @returns for others: Element[] (NodeList)
export const $ = cssSelectorString =>
? document.querySelector(cssSelectorString)
: document.querySelectorAll(cssSelectorString);

Client-side SSL

For excessively paranoid client authentication.

Updated Apr 5 2019:

because this is a gist from 2011 that people stumble into and maybe you should AES instead of 3DES in the year of our lord 2019.

some other notes:

apollo-directives library proposal

apollo-directives library proposal

resources used to learn:

the proposed library aims to resolve this quote, and commonly shared opinion, from the Schema Directives docs:

...some of the examples may seem quite complicated. No matter how many tools and best practices you have at your disposal, it can be difficult to implement a non-trivial schema directive in a reliable, reusable way.

what do the command line notations mean

it can be frustrating but it was likely left out because writing a CLI is predicated by having seen this notation used in the documentation when using a CLI.

to answer your question though (and a bit extra because i was there once too):

when you see $ this is almost always used to indicate that everything after the $ is a single line to paste into the command line (shell) and hit enter. it will usually be in this general form

$ program command <required arg> [optional arg]
