How Phoenix LiveView Form Auto-Recovery works.

Wed, 13 Mar 2024 12:00:00 GMT

Phoenix LiveView is a server-side frontend framework and with this great power comes great responsibility on the developer. A very common source of frustration is around Forms, their assigns values and connection resets or deploys. In this post we'll discuss how this all works and how it enables F...

What if S3 could be a fast, globally synced, Key Value Store? That's Tigris

Tue, 20 Feb 2024 12:00:00 GMT

We’re Fly.io and we transmute containers into VMs, running them on our hardware around the world. We have fast booting VM’s, so why not take advantage of them?

That said... building applications that span the globe is a ...

Not every Dependency is worth it.

Mon, 22 Jan 2024 12:00:00 GMT

Elixir has been quietly building out a truly impressive list of packages, and while a deep resource of packages that solve common or complex problems is good, for some people it's not enough and want more. Which is to be ...

Using LLama.cpp with Elixir and Rustler

Sun, 5 May 2024 12:00:00 GMT

Recently I started playing with the idea of using LLama.CPP with Elixir as a NIF. Creating C/C++ Nif's in Erlang is kind of a project and you need to be especially careful to not cause memory errors bugs. So I found a Rust Wrapper around LLama.cpp and since I have some GPU or paying for Open AI API access. At the moment, Fly.io's GPUs aren't publicly available, but I still wanted to join ...

DIY Lambda

At Fly.io, we make it super easy to spin up new apps and scale them to Machines distributed around the globe. Also, Elixir is uniquely suited to take advantage of this distributed global network. In this post I am going to show you how to use both to:

Streaming uploads with LiveView

Mon, 21 Aug 2023 12:00:00 GMT

Time to face reality. Sending files over the internet via a web browser is not a solved problem. There has been so many bytes spilled on the varied ways of accepting, uploading, streaming, verifying, storing, backing up, and sharing files from a user. It's 2023, and I realize I'm not getting a fl...

BEAM Clustering made Easy

Mon, 14 Aug 2023 12:00:00 GMT

hello One of the reasons Fly.io is so great for Elixir and Phoenix is that we have servers in nearly every region on the globe, and they are all connected via built in WireGuard networking. As an Elixir developer, this is an incredible opportunity because it means we get to use Erlang Distribution...

Let's search the docs of every Elixir Package!

Tue, 8 Aug 2023 12:00:00 GMT

I love ExDocs, I think they are one of the best parts about the Elixir Ecosystem and I frankly cannot shut up about it. My one complaint is that it can sometimes be hard to find exactly what you are looking for us...

Elixir Docs are Built different

Thu, 6 Jul 2023 12:00:00 GMT

A few common refrains from developers who are new to Elixir are:

"Where are the blog posts?"
"Stack Overflow?"
"Google was no help..."

And I totally get it, if you come from another language ecosystem, you would be right to prioritize tutorials or blog ...

Mon, 26 Jun 2023 12:00:00 GMT

Here is a standard Elixir example, reading from a file, mapping over it, filtering over it, converting it into a map:

Whisper text to speech transcription to your voice chat app and while it works great... the boot times on your deployment have slowed to a crawl. Or maybe you really lo...

Resizing Images With Elixir
Mon, 13 Mar 2023 12:00:00 GMT


        We accept user uploaded images and later want to use them as in our applications. This leads to many questions:

What format will their device upload? Which format do we accept? Which format do we use?
How many bytes is the upload and do we want to pay to serve that?

Single File Elixir Scripts
Wed, 8 Mar 2023 12:00:00 GMT


        Elixir has powerful built in scripting functionality, allowing us to write elixir to a file, say my_script.exs and execute it directly by elixir my_script.exs. The vast majority of production elixir projects should be directly compiled via mix with all available optimizat...

        


Phoenix LiveView and SQLite Autocomplete
Thu, 16 Feb 2023 12:00:00 GMT


        In our last post we saw an example of how we could use the built-in Full Text Search capability, FTS5, of SQLite3 to create a search index and query it with Ecto. We also know it's fast to query and especially so since it is in memory.
Let's see how easy it is to show those results...

        


SQLite3 Full Text Search And Phoenix
Tue, 31 Jan 2023 12:00:00 GMT


        Hello
One of the benefits of Sqlite is that you can lightning quick query times because your database is colocated next to your server. Bonus it also comes with built in Full Text search capabilities! But how does this work with Ecto?
In this Series we will walk through

Copy to Clipboard with Phoenix LiveView
Wed, 25 Jan 2023 12:00:00 GMT


        Problem
When you need to make sure a user copies an important string of text, don't let their mouse and keyboard stand in the way. Give them a button to press so they don't need to manually move a cursor around.
But how might you do this with LiveView? It's not like our servers hav...
