Add language server directories to project .gitignore file
# Language server directories
/.elixir_ls/
/.elixir-tools/
Create authentication in Phoenix project:
mix phx.gen.auth Accounts User users --hashing-lib argon2
Add common dependencies
{:credo, "~> 1.7", only: [:dev, :test], runtime: false}
{:mix_unused, "~> 0.4.1", only: [:dev, :test], runtime: false}
{:sobelow, "~> 0.13", only: [:dev, :test], runtime: false}
After installation you need to add :unused as a compiler to the list of Mix compilers in project function
compilers: [:unused] ++ Mix.compilers()
Then you just need to run mix compile or mix compile --force as usual and unused hints will be added to the end of the output.
Run mix hex.audit after adding a dependency or from time to time to check for retired hex package*
