I wrote a blogpost/tutorial around how to build a nest form with LiveView for editing a one-to-many parent schema including all its children. There’s a lot of good reasons why people are strugging with those forms in LiveView, so I hope this is helpful in showing how things can work, but also providing insight into the underlying reasons for how the involved parts work.

Elixir/Phoenix Security: Denial of Service Due to Atom Exhaustion
Wrote a blog post about why creating atoms at runtime is a bad idea, and how to prevent this in your own Phoenix apps.

A while ago, I asked a question about splitting strings on unicode word boundaries. Since then, I actually went on to solve the problem and it turned to be more interesting than I originally thought (spoiler: it ended up involving Rust and a NIF).
This is the end result, in case you are interested: Chunking strings in Elixir: how difficult can it be?

@aochagavia, really enjoyed your post and your findings. As you may recall from our conversations at the time you were looking at unicode_string, the fact that it barfs on invalid UTF8 is definitely an irritant and due to the fact that the unicode break algorithms (line, word, grapheme) are all regex-based. This probably also is the reason the performance is not linear to the length of the string.
Now I feel challenged (in a good way) to do better. And over coffee this morning think I worked out it won’t be too hard to hand-compile the regexes into Elixir pattern matches with sub-binary optimisation. This should make matching more resilient, more performant and more linear.
I’ll report back after I run some experiments!

This one is about how to build forms dynamically without writing a single line of HTML by using JSON Schemas. Just define your form as JSON file and BOOM! It’s live
If you have many forms that differ just slightly, this one is for you!
