In episode 84 of Thinking Elixir, We talk with Chris McCord about the LiveBeats project he created. It’s a high-quality, showcase, open source project that highlights new and powerful features in LiveView. LiveBeats is a social music playing application that challenges current ideas about what LiveView is able to do. It uses presence, new JS features, defines reusable Tailwind styled components, includes accessibility and more! An exciting project that people can actually use in addition to being a great community resource. We also get into what’s coming out in Phoenix 1.7 that may interest people getting ready to start a new project!

Links

• https://github.com/tashirosota/dynamo_migration
• https://hexdocs.pm/dynamo_migration/readme.html

Usage

1. Create migrations table.

   $ mix dynamo.setup

2. Generate and rewrite migration file.

   $ mix dynamo.gen.migration create_tests_table

   # priv/dynamo/migrations/20220130083004_create_tests_table.exs
   defmodule Dynamo.Migrations.CreateTestsTable do
     def change do
       # Rewrite any migration code.
       # Examples.
       ExAws.Dynamo.create_table(
         "Tests",
         [id: :hash],
         %{id: :number},
         1,
         1,
         :provisioned
       )
       |> ExAws.request!()
     end
   end

3. Migrate.

   # Executes `priv/dynamo/migrations/*` if there had not migrated.
   $ mix dynamo.migrate
