Backend

I’ve been reviewing a few things recently around how we are not only using Elixir at Sauce, but also how we are deploying and hosting it.

This one’s going to be really quick: We have a list and we want to split it into 2 sublists based on some condition, to work on each of them separately.

Disclaimer: this piece of knowledge might be a flag that you need to restructure your code, but knowledge is power so there you have it.

LiveView provides real-time user interaction within an application. Some use cases where LiveView fit excellently in an application are input validation, button click, autocomplete and live search.

There are times when the we need to convert a list of string IDs into integer. This operations can be handled using the Enum.

There are times when we need to do multiple operations at once on various database tables. For example, when creating a new entity, such as a user, we might want to also insert a related property in some other table, such as a table that holds the preferences of a user.

You’re building an app that needs to present a calendar of the current month to the user, where do you start?

Elixir is confusing. Here’s one of the reasons: iex> true and false and iex> true && false do the same thing.

Sometimes, we’d like to have function calls depending on certain conditions, such as whether the role of a user is admin or just a mere peasant.

CircleCI is a really useful tool for ensuring that your builds go through correctly, that all the libraries and dependencies are accessible and compatible when building clean, and so on.

More often than not when we run our test suites there may be a few tests that fail so we go ahead and modify our code then run the test suite again.
