var toolbar = quill.getModule('toolbar');
toolbar.addHandler('image', showImageUI);
let saveToServer = (file) => {
//get the data
const fd = new FormData();

Tips on how to use a KV namespace with Cloudflare Pages
This gist aims to show you how to use KV datastore using Cloudflare pages. The reason I created this quick guide is it took
me almost 2 weeks to get it working, mainly because it is very new and the documentation is not up fully fleshed out yet
https://developers.cloudflare.com/workers/runtime-apis/kv
https://developers.cloudflare.com/pages/platform/functions
https://blog.cloudflare.com/wrangler-v2-beta/
Steps:
Install wrangler 2

Fetch the files using the Strapi API so we they can be used in our eleventy static site without having to call back to the API.
IN THE ELEVENTY API FILE
const superagent = require('superagent');
let env = require('./env')
//this function gets some date from and API which can be used in the data processing, for simpluicty stakes it is connection to our auctions endpoint so you can see
//it in action

Our frontend websites are simple flat HTML files created in a JAM stack fashion we recently moved Strapi as our back end CMS and it saves assets images in an uploads directory. We wanted to be able to render these images out of content blocks and repurpose them in our static sites without having to call the API each time
//API Data preprocessing can happen here
const superagent = require('superagent');
let env = require('./env')
//this function gets some date from and API which can be used in the data processing, for simpluicty stakes it is connection to our auctions endpoint so you can see
//it in action
