This package integrates Intertia.js with Phoenix following the Inertia.js protocol. Inertia.js lets you quickly build modern single-page React, Vue and Svelte apps using classic server-side routing and controllers.

Yes, the Elixir. I’ve decided to use the cold February weather, as well as the relative project calm, and see how far I can go with it.
The diamond-square algorithm is a method for generating heightmaps for computer graphics. It is a slightly better algorithm than the three-dimensional implementation of the midpoint displacement algorithm which produces two-dimensional landscapes. It is also known as the random midpoint displacement fractal, the cloud fractal or the plasma fractal, because of the plasma effect produced when applied.
I recently needed to enforce a database constraint similar in spirit to a unique index, however the criteria for what should be considered “unique” was more complex than what a simple unique index in PostgreSQL would be able to deal with. Knowing that Ecto works by intercepting an error raised by the database, I set out to see if I could implement the complex unique constraint logic in the database and still be able to use the Ecto.Changeset.unique_constraint/3 validation without needing to modify any Elixir code.
By the end of this article, we will have a simple Phoenix application that will run tests using CircleCI, then can be deployed by pushing a Git tag to your repository.
After a long week of dealing with servers at my day job I had no urge to do the same with my side projects. I looked at Render.com and decided to try them out. All was well until I decided to add a mix package that built a Rust NIF. The default build container used by Render for Elixir projects didn't include Rust but after chatting with their team on Slack I came up with a solution, Docker.
