How would you do this the "Elixir Way?"

Questions / Help

Like a recent previous poster, I like to write API clients. (because I consume a lot of APIs)

I have one I use a lot, written in PHP, and I’m trying to rewrite it in Elixir to help me learn. I am very new to Elixir and have only read the Introduction to Elixir book.

My question is this:

As a user of Elixir, how would you expect to interact with an API client like this?

This is a contrived example of how it is done in my PHP library:

<?php

$hubspot = new Hubspot($config);


# Use API client to get all contacts
$response = $hubspot->contacts()->all();


foreach ($response->contacts as $contact) {
    # Use API client to update contact, changing all firstnames to Joe
    $hubspot->contacts()->update($contact->vid, [
        [
            'name' => 'firstname',
            'value' => 'Joe'
        ]
    ]);
}

Using that example, is there an easy comparison?

Here’s an example of pulling some records from AWS’s DynamoDB, and updating each.

Dynamo.scan("users")
|> ExAws.stream!(config)
|> Stream.map(&Dynamo.put_object("users", %{&1 | name: "Joe"} ))
|> Stream.map(&ExAws.request!/1)

One issue with direct comparisons like this though is that I don’t know enough about what’s implied by updating each contact in your case to know at what level of abstraction we’re working. For example, you’ll notice that I explicitly have to mention the users table that we’re using from Dynamo. However I could also wrap that inside some User module, and abstract away explicit ExAws calls so that it looked more like

User
|> DB.stream
|> Stream.map(&User.update(&1, name: "Joe"))
|> DB.perform

There are endless possibilities.

Thanks.

For my example, all the update really does is send an HTTP request using another HTTP client library behind the scenes and returns the response:
