At the bottom of the hour, I will be a guest on the Talk Python podcast to talk about #eventSourcing. Come join us!

I recently talked with @bbelderbos
about #eventSourcing, #dataStar, and other thoughts that have transformed how I write code today.

Especially considering that the SSE option incrementally updated two separate parts of the page on each loop.

[Chris May @_ChrisMay]

I just ran an experiment rendering a status page that includes a table of 200 items pulled from the database.

Option A: streaming HTML that is generated on the fly

Option B: Load the shell and leverage #DataStar and Server-Sent Events to populate the table and related data.

[Chris May @_ChrisMay]

Lighthouse reports that the SSE version renders in half the time as the streamed HTML.

This is not what I was expecting.

Fascinating to see that in this instance that SSE is so much faster.

Bookmark this top-notch article on htmx and datastar! Code examples, a narrative, and clear writing

My takeaway: If you are using htmx and you feel like you're putting too many of your front-end controls in the html, datastar is probably the perfect hypermedia solution for you

[Chris May @_ChrisMay]

@all__hype Yeah! Excellent. Thanks for your thoughts!

[Chris May @_ChrisMay]

I finally pushed publish on why I moved from HTMX to Datastar.

I'd love to know your thoughts!

@all__hype @ThePrimeagen @aarondfrancis @htmx_org @codegirl007 @atdeastl @typecraft_dev @tonyennis @robbiewagner @duncanthedev @kenwheeler @WarrenInTheBuff @goodtweetsalex @SledgeDev @dennisivy11 @TurnerHoughton Great job selling the audience displeasure of Warren. I was confused listening to the podcast, but the video was a masterpiece.

While I am not using this package in production, I learned a **LOT** from creating toy projects with it.

Let me know what questions you have lingering from my series. I'll answer them in another post.

[Chris May @_ChrisMay]

It's been a few months since I posted, but I just published article 5 of my intro to event sourcing blog series!

In it, I show you how to get started with event sourcing by using the eventsourcing PYPI package.

[Chris May @_ChrisMay]

@all__hype Yeah! It’s great!
And I love the vibe you and Carson have.

[Chris May @_ChrisMay]

@all__hype Let’s face it, every episode

[Chris May @_ChrisMay]

@all__hype Thank you so much!
By the way, I'm really enjoying your latest episode.

[Chris May @_ChrisMay]

My talk at FlaskCon is up!
In this 20-minute talk, I share how three of my favorite attributes of event sourcing can empower reactive web apps that are better than the status quo.

[Datastar Cult Leader @DelaneyGillilan]

Death to SPINNERS! Thanks for the talk!

@masonegger OMG! I needed that laugh.
My condolences for your time on the Severed floor. ;D

[Chris May @_ChrisMay]

I added a duration column and regenerated the view from past events. Seeing the data appear through the #HTMX powered Server-Sent Events connection was fun.

Event sourcing made answering their question simple, going back to the first file we processed.

[Chris May @_ChrisMay]

I had a win highlighting why I have been excited about #eventSourcing.

My project processes files in multiple phases, and I built a status page to track progress. It became apparent that the team needed to know how long each file took.

[Chris May @_ChrisMay]

@all__hype But thanks for sharing your experiences. You helped me connect some dots I hadn't yet with data-star.

[Chris May @_ChrisMay]

@all__hype FWIW, you can also leverage server-sent events with HTMX. I'm doing that on my current project as a step to prepare for trying out data-star.

[Chris May @_ChrisMay]

@all__hype From your interview with Delany, I realized one could return an event stream from any request, so I have an element that tells HTMX to connect to the SSE stream. That function yields HTML updates to that element (in an event stream format) and OOB swaps.
