skiplistrs VS jsynchronous

Sure - here's a simple fuzzer from a rope (fancy string) library I wrote a few years ago back when I was still learning rust. (Don't judge me!):

https://github.com/josephg/skiplistrs/blob/master/tests/test...

In a loop it simply randomly decides whether to insert, delete or replace some text, and after any action checks that the state is valid (In this case via a call to check2()).

You can go way deeper with this sort of thing if you want, with more complex models, random item generation and simplifiers to help pare down problems to simple test cases. And you can have more complex state - for example, where you also track interaction between multiple items. For example, if your state is a few users, and you also track one user paying another user and verify the total balance across all users is unchanged.

But you don't need to go deep for fuzz testing to be worthwhile. Even something as simple as this little loop is a remarkably effective bug finder.

A data-synchronization library for Node.js

Ever get tired of sending API requests and JSON payloads? Wouldn't it be cool if data just synced between server and client?

Jsynchronous lets you share deeply nested object/arrays between node.js and connected browsers – and any changes made to that variable.

For the very reasons listed in the article, I built:

https://github.com/siriusastrebe/jsynchronous

a library for keeping a javascript variables synchronized between Node.js servers and clients.

Websockets work great for message passing but it struggles with data structures more complicated than what JSON can represent. Jsynchronous syncs any javascript object or array with arbitrarily deep nesting and full support for circular data structures.

If a computer goes to sleep, or disconnects, websocket connections (and their underlying TCP connections) get reset so you lose any data sent while a computer is unavailable. Jsynchronous will re-send any data clients are missing.

There's also a history mode that lets you rewind to past states.

I recently built https://github.com/siriusastrebe/jsynchronous which uses event sourcing to synchronize javascript variables on the server with connected browsers.

You can also replay states using a special “rewind” mode, a core advantage of event sourcing.
