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.

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!

Sveltekit SPA Mode: Prevent serverside code
I am using rxdb which internally uses some folder imports like import x from './folder' as opposed to import x from './folder/index.js which is big nono inside node.js environments.

For anyone who wants to not only make jokes but actuall learn something, I recommend to start with exploring the github repo: https://github.com/pubkey/rxdb

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.

[DDD] Tactical Design Patterns Part 3: Presentation/Infrastructure Layer
We decided to use MySQL for a database. and TypeOrm for ORM. The ER diagram is provided below. For example, the task_assignments table holds information about user assignments to tasks. While in DDD, there is a pattern to design denormalized tables that reflect the structure of domain objects more directly, but this time, a more conventional table design was chosen. TypeOrm models:

SQLSync – Stop Building Databases
How does this compare to using directly an ORM lib that supports browser like TypeORM [0] via SQL.js [1]?

Deno Cron
* Patch a third-party library that was setting an HTTP header to `null`. NodeJS handles this case just fine, but Deno throws an error [2].
After all of that work, I finally was able to use Deno in my project. It was really cool! Unfortunately, both VS Code and IntelliJ with Deno are essentially unusable [3]. Or, at least, unacceptably slow compared to what I had with NodeJS.

Authentication part 3 using NestJS and Postgres database neon.tech
We are going to start using TypeORM as an ORM to help us interact with Postgres, but we also have an example of using Prisma in the future and everything that we have to adapt to switch the ORMs if necessary. At the end we are implementing neon.tech as a production database, right? 😉

From Good to Great: Scaling Applications with TypeORM Optimization
TypeORM is a popular Object-Relational Mapping (ORM) library for Node.js. It provides a high-level abstraction over relational databases, making it easy to perform CRUD (Create, Read, Update, Delete) operations.

Top 6 ORMs for Modern Node.js App Development
TypeORM places its focus on TypeScript and JavaScript (ES7+) development. It offers compatibility with various database systems, including MySQL, PostgreSQL, SQLite, and MongoDB. What sets TypeORM apart is its robust integration with TypeScript. It provides a user-friendly experience with a convenient decorator-based syntax for defining entities and relationships. Additionally, TypeORM supports the repository pattern and enables eager loading, enhancing its versatility for developers.

Deep Dive into Google Cloud SQL Connector for Node.js
ᴬ typeorm officially supports mssql@v9, but the support for the custom stream builder was added in mssql@v10. Since mssql is a peer dependency of typeorm, you can force override it and use the Cloud SQL Connector with typeorm. There is an open PR to add support for mssql@v10 in typeorm.
