The Composable Web Proposal

Serverless infrastructure like AWS Lambda and Google Cloud Functions have made it much cheaper for developers to offer server-side code for public consumption without keeping a server always running.

If these functions could be declared as stateless or deterministic, costs can be brought down even more because only the first invocation needs to be executed. Cached response could be returned for future invocations with the same input arguments.

All modern browsers support URL lengths of thousands of characters, even on mobile. A lot of data can be embedded and passed around directly in the URLs (instead of passing identifiers which requires a look-up which costs server time).

So here's a thought:

How to use Discord Webhook

It's a JSON

First, learn JSON. It's not programming language, not even close. Just follow syntax rules and you will be fine.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Strictly Frameworks

Mobiledoc - github.com/bustle/mobiledoc-kit - framework to build editors with a standardized JSON structure
ShareDB - github.com/share/sharedb - framework to sync any JSON document using operational transforms, add real-time collaborative editing to anything else
Bangle.dev - github.com/bangle-io/bangle.dev - toolkit built for building editors, based on prosemirror

Abstracted Editors

These use separate document structures instead of HTML, some are more modular libraries than full editors
