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!

NodeJS Security Best Practices
If you use Sequalize, TypeORM or for MongoDB, we have Mongoose these types of ORM tools, then you are safe by default because these help us against the SQL query injection attacks by default.

How to Build & Deploy Scalable Microservices with NodeJS, TypeScript and Docker || A Comprehesive Guide
Our orders microservice will have its own set of teachnologies just like we earlier plotted that is mysql database and sequelize orm. MySQL is an open-source relational database management system (RDBMS) that is widely used for building web applications and managing data. It is a popular choice for many developers and organizations due to its performance, reliability, and ease of use. Sequelize is a popular Object-Relational Mapping (ORM) library for Node.js. It provides a way to interact with relational databases like MySQL, PostgreSQL, SQLite, and MSSQL using JavaScript or TypeScript. It simplifies database operations by allowing developers to use JavaScript objects to represent database tables and records, instead of writing raw SQL queries. In this microservice, we will use it to query our MySQL database.

What Are ORMs & Should You Use Them
However, some ORM operations can’t be translated into a single SQL query that easily. Let’s take Sequelize's findOrInsert. It first sends a SELECT query like this:

Top 6 ORMs for Modern Node.js App Development
Sequelize is an extensively employed ORM for Node.js. It supports relational databases, such as MySQL, PostgreSQL, SQLite, and MSSQL. Sequelize boasts a comprehensive array of features for database modeling and querying. It caters to various coding styles by accommodating both Promise and Callback-based APIs. Moreover, it encompasses advanced functionalities such as transactions, migrations, and associations, making it well-suited for intricate database operations.

Contributing to Tech Communities: How Open-Source can land you a job and get you out of the Skill Paradox 💼
I made a small change to the new documentation for Sequelize! I was just scrolling through the documentation and found this mistake that could lead others to weird debugging sessions, so as soon as I found it, I submitted a PR for them! You can check out the contribution here!

How to connect Next 13.4 application with PostreSQL using Sequelize (or TypeORM)
I tried every solution in this guide https://github.com/sequelize/sequelize/issues/6907 and many others, but I feel that Next 13 is the latest and it is not supporting other ORMs than Prisma. And I am not comfortable working with Prisma due to the absence of migrations, CLI and so much more.

Is this a valid reason to give up node?
I mean I am not really a pro be dev. But there is such tools as https://sequelize.org/ and it can work with different DBs, if your current DB doesn't support this you can always switch to that one which do. Switching to another language doesn't really do much.
