usage

Under construction. See release notes and tests for examples.

The recommended way of making use of this module is to create your own "effects" package giving you seemless pure-functional scala experience without import confusion. It's for developers who realized that you can't really write any production apps without treating cats, cats-effect, fs2 as being standard library.

package myapp

import busymachines.pureharm

package object effects extends pureharm.effects.PureharmEffectsAliases with pureharm.effects.PureharmEffectsSyntax {
  //write your own custom opiniated things here!
}

//everywhere else in your code just do:
import myapp.effects._

//instead of:
import cats._
import cats.syntax.all._
import cats.effect._
import cats.effect.syntax.all._
import cats.effect.std._
import cats.effect.std.syntax.all._
import fs2._
import retry._
import retry.syntax.all._
