_Event-Sourcing Live Coding_

I've been live coding an example #EventSourcing app in #Java (via #TDD) w/o an ES library.

This week I'll continue to code the "Time-Traveling Event Viewer" to view the state at any point in time.

LIVE CODING STREAM THIS WEEK

After an awesome time at #ExploreDDD, I'm back home and ready to continue working on JitterTix, the example #EventSourcing app in #Java, #TDD, a tiny bit of #SpringBoot and no other libraries (well, a few small ones, but not for the EventSourcing).

Ich grübel ja über eine #JUG Tour nach… So ernsthaft mal mit dem Rad durch Deutschland und anbieten, positive darüber zu ranten, warum mir #Java Skripte, Python, HTML + JavaScript ohne Framework-Gescheiß und eine echt coole Datenbank im letzten den Glauben an Software-Engineering ohne AI und Nippes erhalten haben… Würd sich das jemand anhören wollen?

_Event-Sourcing Example App_

Join me in 1 hour (18:00 UTC) as I continue work on JitterTix, an example app demonstrating how to do #EventSourcing in #Java (and #SpringBoot) without ES libraries, but with #TDD.

A screenshot of a Java program that uses the Neo4j JDBC driver to read records from a database, 3 panes, left to right: * On the class path, listing individual imports * On the module path, using preview feature module import declaration (JEP 476), omitting individual imports * On the module path, as implicit declared class, omitting the the java.base import (there by default), and java.sql (required by neo4j jdby anyway)

_JitterTix Event-Sourcing Example_

This week I'll continue working on my JitterTix, an example app for demonstrating how to do #EventSourcing in #Java without any ES libraries.

Join me at 18:00 UTC Mon-Thurs, at https://jitterted.stream. The repo is https://github.com/jitterted/jitterticket-event-sourced

1. Example code for my "TDDing Event-Sourcing" talk (hope it gets accepted at some future conferences!)

2. A platform for experimenting with different ways of implementing event-sourcing in #Java (w/o libraries)

3. Folks in my community asked for an example! (❤️ my community)

_JitterTix Concert Ticketing System_

On my #Java live coding stream this week I've been working on a simple concert event ticketing system that is based on #EventSourcing. I have several reasons I've been doing this (putting my #TDD Game on hold).

People: “Don't use #Lombok’s (At)Data on entities! equals(…) and hashCode() will be wrong!” (For the record: I agree.)

Also people: “Here's how you use #Java records to implement entities.”

🤷‍♂️

Looking forward to visit @JavaLandConf next week. As a start to the program @edburns blogposts are always a joy: https://mastodon.social/@edburns/114071720537653708
