Build a Cryptocurrency Dashboard with Elixir and Phoenix LiveView

alvises

Hello everyone!

I’ve almost finished recording my Elixir and LiveView course! It’s packed with hours of in-depth tutorials, tips and app development.

It’s a journey where we go through the full development of a real LiveView application, which gets real-time data from many Cryptocurrency Exchanges and beautifully renders prices and charts on the browser of (potentially) thousands of users.

In this course we’ll see many topics!

The first part is all about the Elixir application

Crypto Exchanges APIs, WebSocket client with Gun and GenServer, Structs, Typespecs and Dialyzer, Behaviours and Callbacks, Macros, Phoenix PubSub, Application Design and Contexts, Protocols, Supervisors, CI/CD with GitHub actions + Gigalixir, Phoenix

Then we move to the web part, where we use LiveView to render the trades on a real-time dashboard

How LiveView works, Layouts, LiveEEx templates, Bindings, Clicks and Form events, Debounce, Live Flash Messages, Live Components.

And then, an advanced part

LiveSocket params, Real-time charts with JS hooks, Live Navigation, Performance and historical trades with queues and ETS.

You can use the ELIXIRFORUM coupon to get a $20 discount!

If you are just interested to the LiveView part, I’ve just released a free Introductory LiveView course. The lessons are free and standalone extracts taken from the full course.

I bought this course and have gone through it. It’s approach is quite different from other LiveView courses in that it builds a complete application with gen servers, APIs with websockets, and UI using LiveView. Highly recommended.

Thanks for the excellent discount

I really love your way of teaching, at least from all the blog post I read until now.

Any special reason why PayPal is not offered as a payment option?

Thank you!

Because on Teachable, the platform where my course is hosted, to get custom payment gateways I should upgrade from the $39/month plan to the $119/month plan … A bit pricey for that extra option But I’ve received some requests about paypal, so I should maybe upgrade the plan…

That’s pricey for sure.

I guess you need to balance how many clients you may be loosing.

I am not a buyer for now due to the lack of time, but I can assure you that I don’t use any other payment that isn’t PayPal.

The reason is not because trust more in PayPal then Stripe, it’s just because I don’t like to spread my personal info and credit card details across providers, and especially I don’t like the fact that Stripe payments are embedded in the page. This makes me to loose all the credibility and trust in making a purchase in said site, because don’t know in how many places my data is ending up.

I wish all the success in your course, because you have talent to teach, and with no doubts you will succeed

Hi all,

I’ve just published the penultimate lesson of this course, it’s about refactoring the Historical with ETS, using protected tables, insert and getting objects with lookup and select with match specifications.

The ELIXIRFORUM coupon to get the $20 discount is still valid, and I will keep it since completion of the course (a few weeks).

The next and last lesson will be about using :queues to efficiently keep a window of recent trades in memory.
