Palabres

Palabres [\pa.labʁ\]
French word, coming from the Spanish word palabra, meaning “parole” & “word”. \

  1. Long & hard discussion to get a precise result.
  2. An interminable and often idle discussion.

Palabres is an opinionated logger, built in Gleam for Gleamlins, targetting both Erlang and JavaScript. Palabres tries to be compatible with the most runtimes possible, so you can expect it to work on BEAM & any flavour of JavaScript — with 100% compatibility while the runtime respect Node.js imports.

Palabres tries to stay simple yet powerful. By using structured data, text messages and potential metadata, Palabres tries to provides a nice and pleasant experience out-of-the-box with few to no configuration and helps to build & monitor complex system.

But what does it look like?

Generally, when you’re starting out a project, you rely on the default logger, with its default abilities. However, in the long run, you probably want to add context, to add advance monitoring, to follow user flows, and much more, in your logs. Outputting plain text in such case can make the task hard. That’s where Palabres comes into play, it helps you to go from

Getting started

To get started, everything you need is to configure your logger, and you’re done! Everything remaining is to use Palabres to create logs!

import palabres
import palabres/options
import palabres/level

pub fn configure_logger() {
  options.defaults()
  |> options.color(True)
  |> options.json(False)
  |> options.output(to: options.stdout())
  |> palabres.configure
}

pub fn log_message() {
  palabres.debug("My debug message")
  |> palabres.string("my_field", "content")
  |> palabres.int("my_other_field", 12)
  |> palabres.log
}
