Describe the Bug
I'm trying to use CE javascript SDK in a React app. I have the following err:

ERROR in ./node_modules/cloudevents/dist/transport/http/index.js 16:31-46

Module not found: Error: Can't resolve 'http' in '/home/ksuszyns/git/openshift-knative-showcase/frontend/node_modules/cloudevents/dist/transport/http'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
	- add a fallback 'resolve.fallback: { "http": require.resolve("stream-http") }'
	- install 'stream-http'
If you don't want to include a polyfill, you can use an empty module like this:
	resolve.fallback: { "http": false }

That error is thrown just after trying to create the CE:

const ce = new CloudEvent({})

I just wanted to parse incoming Server Sent Events data that is in structured-mode CE.

Steps to Reproduce

1. Create React app with: npx create-react-app frontend --template typescript
2. Install CE: npm i --save cloudevents
3. Import CE and attempt to create basic object:

   import { CloudEvent } from 'cloudevents'
   
   const ce = new CloudEvent({})

You can also see this error on this commit: cardil/openshift-knative-showcase@cc8ffe2

Expected Behavior

I just want to create basic CE objects, in React app. And parse them from the JSON text, in the near future. No errors should be thrown.
