Setup Instructions

Development

To get BlockScout up and running locally:

• Install dependencies with $ mix do deps.get, local.rebar, deps.compile, compile
• Create and migrate your database with $ mix ecto.create && mix ecto.migrate
• Run IEx (Interactive Elixir) to access the index and explore: $ iex -S mix

Testing

• Format the Elixir code: $ mix format
• Lint the Elixir code: $ mix credo --strict
• Run the dialyzer: mix dialyzer --halt-exit-status
• Check the Elixir code for vulnerabilities: $ mix sobelow --config

Benchmarking

Explorer.Chain.recent_collated_transactions/0

• Reset the test database: MIX_ENV=test mix do ecto.drop, ecto.create, ecto.migrate
• Change tag in benchmarks/explorer/chain/recent_collated_transactions.exs to a new value, so that it will compare against the old values saved in benchmarks/explorer/chain/recent_collated_transactions.benchee
• Run the benchmark: MIX_ENV=test mix run benchmarks/explorer/chain/recent_collated_transactions.exs
