hexpm VS Ruby on Rails

I was thinking of porting this library to Elixir. But first, I searched on hex.pm and Surprising. I found two packages that support merging tailwind classes: twix and tails

I often reference https://github.com/hexpm/hexpm which is the code behind hex.pm.

Feel free to take a look at the package manager and let me know if there are any libraries that you need that are missing. https://hex.pm/

I can assure you I'm not spending my time inventing new libraries. In the past 3 or so years of working in Elixir there have been maybe 2 or 3 cases where I was looking for a library and couldn't find a suitable one. Writing my own code to cover those cases took a few hours. This should hardly be a deal breaker for anyone if you take into account dozens, maybe even hundreds of hours the ecosystem could save you in the long run if your project is a good fit for it.

Before getting started you need to have both Elixir, the Hex package manager, the PostgreSQL relational database server and Node.js installed on your local computer to be able to follow through this guide.

We can then look at that function and see that ultimately it calls Supervisor.start_link(...) on a bunch of children. That means that one process's only job is to start up all those child processes and "supervise" them, meaning if any of them crash it will be notified and be able to handle that. I note that one of the processes runs the code in the module Hexpm.RepoBase which means it's in charge of managing database connections, and one runs the code in the module HexpmWeb.Endpoint which is the process in charge of managing the Phoenix side of things, handling incoming requests, spinning up new processes to handle each one, and directing them to the right controllers and stuff. Then there's a bunch of other modules listed, for things like rate limiting, billing reports, and other stuff. You can look in the codebase for those listed modules if you're interested, but the thing to note is that by putting the module name there, what happens is the supervisor will spawn a new process and run the start_link function of that module within that new process.

I was looking for a solution to run tests automatically every time I save any changes. The best way so far for me is the following hex package:

Now it’s time to decide on a name for your package. In this guide I will be creating a new Ueberauth package. If you were to go on http://hex.pm and look at other Ueberauth packages, you notice there is a certain pattern followed. This will make the decision easy for us on what to call our Uberauth package that will implement the Patreon OAuth flow.

Go to the website https://hex.pm and search for the faker library to grab the latest version, so you can copy that to your mix config file, at the time of the making of this tutorial the latest version is 0.17.0, add the following to your project dependencies inside your mix.exs file:

[0] is a my favorite demonstration of it.

Here's a real life example: Imagine a Ruby on Rails app on which a team of developers are working. The code is hosted on GitLab and all the work is coordinated using GitLab issues. In other words: For every commit, there's an associated issue and the issue number acts as a sort of primary key for documentation, time reporting and so forth. This convention has a few advantages, most notably the ability to easily learn more about how, when and by whom features were implemented as well as how this implementation came to be.

Ruby on Rails is regarded as one of the best ruby frameworks. It was the primary language in developing big projects such as Twitter and helped the language boost the community. Often referred to as “Rails,” Ruby on Rails is a web development framework with an MVC control structure and currently running its 6.1 version. The 16-year-old language has dramatically influenced the web development structures and managing databases, web pages, and other components on a web application.

In Rails 7.1, a new option _instance_methods is introduced, allowing developers to opt-out of the automatic generation of instance methods for enums. When enum is defined with _instance_methods: false, Rails will no longer generate methods like pending?, processed?, etc.

Rails isn't super opinionated about database writes, its mostly left up to developers to discover that for relational DBs you do not want to be doing a bunch of small writes all at once.

That said it specifically has tools to address this that started appearing a few years ago https://github.com/rails/rails/pull/35077

The way my team handles it is to stick Kafka in between whats generating the records (for us, a bunch of web scraping workers) and and a consumer that pulls off the Kafka queue and runs an insert when its internal buffer reaches around 50k rows.

Rails is also looking to add some more direct background type work with https://github.com/basecamp/solid_queue but this is still very new - most larger Rails shops are going to be running a second system and a gem called Sidekiq that pulls jobs out of Redis.

I'm looking forward to see what extractions from this will land on rails. For example: https://github.com/rails/rails/issues/50454

Here is what strict_loading does (source):

Kamal is a wonderfully simple way to deploy your applications anywhere. It will also be included by default in Rails 8. Kamal is trivial, but I don’t recommend using it on your development machine.
