Improve documentation around using KVStore from code

[joladev]

There are examples of how to set up bindings using the CLI but nothing for running it programmatically.

Through trial and error I've managed the following

// @ts-ignore
import Cloudworker, { KeyValueStore } from '@dollarshaveclub/cloudworker';
...
  const keyStore = new KeyValueStore();
  store.put('key', 'value');
  const cw = new Cloudworker(script, {
    bindings: {
      STORE: store,
    },
  });

Note that TypeScript errors on that import with has no exported member 'KeyValueStore'. Not sure how to fix that, maybe I'm importing it wrong?

Anyway, if this looks right I can make a PR with a simple example of using the KV Store to the README.

You can make the import using require for CommonJS library, no need to go ES6 style.

const Cloudworker = require('@dollarshaveclub/cloudworker')


const simpleScript = `addEventListener('fetch', event => {
    event.respondWith(handleRequest(event.request))
  })
  
  async function handleRequest(request) {
    const response = await fetch(request)
    console.log(await STORE.get("test"))
    return response
  }`

  const store = new Cloudworker.KeyValueStore();
  store.put("test", "helloWorld");
  
  const req = new Cloudworker.Request('https://www.google.com/')
  const cw = new Cloudworker(simpleScript,  {
    bindings: {
      STORE: store,
    },
  })
  cw.dispatch(req).then((res) => {
    console.log("Response Status: ", res.status)
    res.text().then((body) =>{
      console.log("Response Body: ", body) // 
    })
  })
