I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

owservable core: reactive data protocol, stores and backend interface

owservable

@owservable/core

📖 API Docs · ✅ Coverage

The database-agnostic heart of the owservable reactive stack: the websocket subscription protocol, the reactive stores, and the IObservableBackend interface that database adapters implement.

Pair it with a backend adapter:

@owservable/mongodb — MongoDB change streams via mongoose
@owservable/postgres — PostgreSQL LISTEN/NOTIFY via MikroORM
@owservable/sqlite — SQLite journal-trigger live updates via MikroORM (cross-process capable)

🚀 Features

OwservableClient: per-socket subscription manager speaking the owservable wire protocol (subscribe/unsubscribe/reload, update/increment/total/delete)
Reactive Stores: CollectionStore, DocumentStore, CountStore — RxJS subjects that reload and re-emit when their backend reports relevant changes
IObservableBackend: the interface adapters implement (change feed + query execution); stores never touch a database driver
BackendRegistry: maps observe targets to registered backends, across any number of databases
Actions runtime: cronjobs, workers and watchers wiring via @owservable/actions
Data middlewares: per-channel payload post-processing via DataMiddlewareMap

📦 Installation

npm install @owservable/core

or

pnpm add @owservable/core
