[Provide seminars project] Training topics

Let's share what we think should be the focus for training. There are no bad ideas, so don't be shy :)

how to setup a small web server in elixir?

[miriampena]

how does a gen_server work?

how does a gen_server work?

Yes and supervision, supervision, supervision.

how to setup a small web server in elixir?

Yes, but taking that idea further... build a web framework from scratch. No plug, etc. That might be too much depending on time.

Here is some existing work that can be leveraged: https://elixirschool.com/en/

Training focused to use existing tools, kinda the opposite approach of "building from scratch", maybe we call it "use the wheel, use it well" :)

• boot up a webserver
• connect it to a database
• build a release?
• deploy it to Heroku (free) or Gigalixir (free)

@pdgonzalez872 Ahh I see. 👍

I meant setup one web server, not build it . so you just get your endpoint working.

@starbelly , creating your own is also an interesting topic. Not shutting anything down at the moment. Keep them coming!

@pdgonzalez872 haha no worries... I like to take people to the deep end of the pool 😁 But that's not the context here, so no worries.

The ideas we had for the following sessions at NextRoll (the training was interrupted because it was for people in SF and I'm living in Barcelona, Spain now… so we still need to figure out a schedule that works):

• Intro to OTP
  • A bit of history
  • What comes in the box? (i.e. an overview of tools and libraries)
  • Behaviors 1:1 (i.e. recognizing common patterns and abstracting them)
  • Existing behaviors and when to use each
• Deep dive into gen_server
  • When should we use one?
  • Writing tests for a gen_server
  • Required and optional callbacks
• Building a supervision tree
  • What is a supervisor and when to use it?
  • The different restart strategies
  • The different kinds of supervisor
  • The different kinds of children and when to use each one
  • Testing supervisors
  • Supervising supervisors and building supervision trees
  • Tips on how to better build your trees in different scenarios
• Building an application
  • What is an OTP application and when to use it?
  • Required and optional callbacks
  • The application environment (including config files)
  • Managing apps with rebar3 (the basics, including dependencies)
  • Testing applications
  • Distributed applications
• Releases
  • <insert stuff about releases here>
