Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.
The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows
the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir
and you are good to go.
Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to
a specific version, you will need to compile it yourself. Then asdf
is your best friend.
This document is a collection of concepts and strategies to make large Elm projects modular and extensible.
We will start by thinking about the structure of signals in our program. Broadly speaking, your application state should live in one big foldp
. You will probably merge
a bunch of input signals into a single stream of updates. This sounds a bit crazy at first, but it is in the same ballpark as Om or Facebook's Flux. There are a couple major benefits to having a centralized home for your application state:
