I'm considering learning Elixir

Fantastic! Elixir is in a unique place in the web development ecosystem. It's both extremely performant as a web server and extremely high-level and productive. Furthermore it inherits some unique concurrency and fault-tolerance super-powers from Erlang.

Elixir's greatest drawback is that it's a relatively young language and while it's well past version 1.0, it doesn't have the incredible library ecosystem of a language like Ruby or PHP. It's best fit is for entrepreneurs and experienced developers looking for a competitive edge, people looking to learn a rock solid concurrency model and early adopters.

I'm an Elixir beginner

Alchemist Camp is especially tailored to beginners. Lesson 1 starts from an assumption that you have done some programming and know what variables and functions are, but that you know no Elixir whatsoever. The first few projects don't use any dependencies and then we gradually start working with Mix, Ecto, HTTPoison, Phoenix and more.

Recommended episodes:

• Lesson 1: The Guessing Game
• Lesson 2: Word Count
• Lesson 3: Minimal Todo P1
• Lesson 4: Minimal Todo P2
• Lesson 5: Mini-Markdown
• Lesson 6: Alchemy Markdown
• Lesson 7: CLI Applications with Escript
• Lesson 8: Game board
• Lesson 9: State Machine through Pattern Matching
• Lesson 10: Finishing Tictac and making a CLI (optional)
• Lesson 11: Finishing Tictac and making a CLI (optional)
• Lesson 11: A worker to log stats (start of StatWatch project)
• Lesson 12: Constructing bitmap files with Elixir
• Lesson 13: Adding Ecto and a Postgres database to StatWatch

After going through these videos you should be comfortable enough with the Elixir language to have a much easier time learning Phoenix or other popular Elixir-based tools and a good idea of what you're interested in next.

I want to learn Phoenix or a specific topic

At the time of this writing there are two full-featured Phoenix projects that have been screencasted in their entirety. Check out the Episodes page and look for episodes tagged StatWatch or CMS

As you may have noticed Alchemist Camp puts more entries into a listing page than even Reddit does. This rejection of card-based design in favor of information density is intentional. If there's a specific topic you're interested in, skim over the page and see if any of the titles or tags look relevant!

I already have experience with Elixir and Phoenix

If you're already experienced, then you'll probably find the most value in the more niche topics, performance tuning and the series that builds a bare-bones framework up from Cowboy.

Recommended episodes:

• Making a site with just the Cowboy server
• Building a router and handling static assets
• Creating a DSL for our router
• Setting up Brotli on Nginx or Phoenix
• Elixir Protocols: a gentle introduction
• Using remote console to access IEx in production
• Caching DB requests with ETS
