View Source Ecto.DevLogger

An alternative logger for Ecto queries.

It inlines bindings into the query, so it is easy to copy-paste logged SQL and run it in any IDE for debugging without manual transformation of common elixir terms to string representation (binary UUID, DateTime, Decimal, json, etc). Also, it highlights db time to make slow queries noticeable. Source table and inlined bindings are highlighted as well.

before and after



The package can be installed by adding ecto_dev_logger to your list of dependencies in mix.exs:

def deps do
    {:ecto_dev_logger, "~> 0.4"}

Then disable default logger for your repo in config file for dev mode:

if config_env() == :dev do
  config :my_app, MyApp.Repo, log: false

And install telemetry handler in MyApp.Application:


Telemetry handler will be installed only if log configuration value is set to false.

That's it.
