Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: How Can I Make My Front End React to Database Changes in Real-Time?
I'm interested in this problem also!
I think there is a large overlap with projects that market/focus on offline-first experiences.
AFAIK this problem can be solved by:
1) Considering a client-side copy of the database that gets synced with the remote DB. This is an approach [PowerSync](https://www.powersync.com/) and [ElectricSql](https://electric-sql.com/) and [rxdb](https://rxdb.info/) take!

You can't leak users' data if you don't hold it
Hey, after I posted that, I went and gave a second look online to see if I could find something that would allow me to develop a local-first app with offline persistence and syncing capabilities.
I ended up finding some possibilities out there that could potentially help me build stuff. One of them is RxDB [1], which offers WebRTC syncing - you'd still need a signaling server, I suppose, but all sensitive information could be synced E2E-encrypted via WebRTC.
Then there's CRDT's [2], which is a universe that turned out to have multiple possibilities that match (at least partially) my needs. In particular, the next thing I want to take a look at is cr-sqlite [3], which might be just thing I needed to kick-off some side-projects.
I'm posting here cause I just found some hope of not needing to build a traditional client-server app and having to deal with all the hassle involved in securing a server (and with fear that my efforts could be not good enough), and I thought someone else could benefit from getting to know these things.

SignalDB: Bringing Meteor-Like Reactivity to the Modern Age
About a year ago, I discovered a cool offline-first framework called RxDB. Initially, I thought that on the frontend side, this was exactly what I had been searching for over the past years. After tinkering around and even using it in production for some time, I realized that it wasn't well-suited for my intended use. RxDB was initially created as an RxJS layer for PouchDB with a server replication interface. Over time, other storage types besides PouchDB were introduced (e.g., IndexedDB, SQLite) and the replication interface became more sophisticated. The replication interface is really cool and exactly what I wanted. The biggest problem I have with RxDB is that it is so tightly coupled with RxJS. While RxJS is technically very powerful, it offers a dreadful developer experience. It's really hard to understand at first and integrating it into an existing codebase, which isn't using RxJS, is tedious.

Show HN: ElectricSQL, Postgres to SQLite active-active sync for local-first apps
Congrats to the team. Once I’ve tried https://rxdb.info/ and it wasn’t funny at all to do the remote replication (PG) and to deal with conflicts. I do need to check this out!

Understanding SQL vs. NoSQL Databases: A Beginner's Guide
On the other hand, NoSQL databases are non-relational databases. They store data in flexible, JSON-like documents, key-value pairs, or wide-column stores. Examples include MongoDB, Couchbase, and Cassandra.

Using SQLite and AI to generate CouchBase code
In my previous article I wrote about how we implemented vectors-based semantic search in SQLite. Afterwards I asked myself what the best use case for this could be. My conclusion was to use the smallest database on the planet (SQLite) to automatically generate code for the largest database on the planet (CouchBase) 😁

SQL is (almost) always superior to NoSQL
With partial record updates, the problem simply vanishes more or less. To understand why, read the above article for details. Some NoSQL database systems do support partial record updates, such as CouchBase if I remember correctly, but most struggles with these kind of constructs.

A comparison of transaction models in distributed document databases
Couchbase was originally developed by merging Membase, a fork of Memcache with on-disk durability, with CouchDB, a somewhat experimental document database written in Erlang. As such, it has a relatively tortured development history. It has adopted a relatively tortured transaction model as well.
