Miniprogram meets Cats Effect

As promised, this is an update from WeApp meets Scala.js leveraging both Scala 3 and Cats Effect

  import Wechat.callback
  val login = for {
    f1 <- Wechat.login
    _  <- IO.println(s"code is ${f1.code}")
    _  <- Wechat.setStorage("code", f1.code)
  } yield ()

  login.unsafeRunAsync(callback => {})

How to use

1. install the customized sbt-less plugin

A customized sbt-less can be found in project/lib, it generates directly .wxss from the .less files, either copy it to your ivy local or add the path in your ~/.sbt/repositories such as

[repositories]
  local
  wechat: file:///{baseDirectory}/project/lib, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]

2. tasks

sbt > fullOptJS
sbt > less
sbt > assets

• fullOptJS compiles scala files to js files
• less compiles less files to wxss files
• assets copies the rest

3. cleanup

Now we have the miniprogram in target after cleanup, Scala.js generates straight ES6 and it fits miniprograms perfectly

shell $ ./cleanup.sh
