A JavaScript environment for Scala.js (a JSEnv) running playwright

Add the following line to your project/plugins.sbt

// For Scala.js 1.x libraryDependencies += "io.github.gmkumar2005" %% "scala-js-env-playwright" % "0.1.8"

Add the following line to your build.sbt

Test / jsEnv := new PWEnv( browserName = "chrome", headless = true, showLogs = true )

• This is a very early version. It may not work for all projects. It is tested on chrome/chromium and firefox.
• Few test cases are failing on webkit. Keep a watch on this space for updates.
• It works only with Scala.js 1.x
• Make sure the project is set up to use ModuleKind.ESModule in the Scala.js project.

   // For Scala.js 1.x scalaJSLinkerConfig ~= { _.withModuleKind(ModuleKind.ESModule) }

• Some projects which may need to use both Selenium and Playwright. If it runs into google exception, add the following line to your plugins.sbt

libraryDependencies += "com.google.guava" % "guava" % "33.0.0-jre"

• chrome
• chromium (same as chrome)
• firefox
• webkit (experimental)

jsEnv := new jsenv.playwright.PWEnv( browserName = "chrome", headless = true, showLogs = false, )

lazy val pwenvConfig = Def.setting { jsenv.playwright.PWEnv .Config() .withKeepAlive(false) } jsEnv := new jsenv.playwright.PWEnv( browserName = "chrome", headless = true, showLogs = true, pwenvConfig.value, )

• Add examples to demonstrate how to use LaunchOptions
• Add feature to keepAlive the browser
• Optimize to use a single browser instance for all tests by creating multiple tabs
• Configure github actions to test this project
• Configure github actions to publish to maven central
• Verify debug mode works
• Verify other test frameworks work
• Verify it works on windows and Linux
