POA Explorer

This is a tool for inspecting and analyzing the POA Network blockchain.

Machine Requirements

  • Erlang/OTP 20.2+
  • Elixir 1.5+
  • Postgres 10.0

Required Accounts

  • Github for code storage

Setup Instructions

Development

To get POA Explorer up and running locally:

  • Set up some default configuration with: $ cp config/dev.secret.exs.example config/dev.secret.exs
  • 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
  • Run the test suite with coverage: $ mix coveralls.html
  • 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
