Last Friday, we announced a ✨ new default structure ✨ for Kotlin Multiplatform projects. (Nothing like a late Friday afternoon release!) In case you missed that, here’s a quick recap of what’s new! 🧵👇

Someone just shared, out of the blue, my project on another social media! That is the first time it ever happened and I was so happy to see that! Sometimes I wonder if I should ever keep working on it, if ever people are using it or not. It felt heartwarming seeing that, tbh!

Metro is so good! If you haven't tried yet, I strongly suggest you to!! I wish IntelliJ allowed non-bundled K2 compiler plugins to contribute their FIR checkers to the IDE so we could see diagnostics in real-time. Perhaps a Metro IntelliJ plugin could bridge the gap until then

Metro 0.13.0 adds top-level contribution providers, Circuit code gen, and a new @DefaultBinding annotation. This also removes most deprecated APIs as Metro prepares to go stable (!!). If you have runtime API feedback, now is the time! github.com/ZacSweers/me...

Today I’m open-sourcing Dejavu! Testing UI performance in Jetpack Compose is frustrating. We profile and watch tools, yet regressions still creep in. I built Dejavu to make recomposition behavior something you can actually test.

A screenshot of code that reads: // Create a Recomposition Tracking Rule @get:Rule val composeTestRule = createRecompositionTrackingRule() @Test fun incrementCounter_onlyValueRecomposes() { // Perform an action composeTestRule.onNodeWithTag("inc_button") .performClick() // Assert that Composables change like you expect composeTestRule.onNodeWithTag("counter_value") .assertRecompositions(exactly = 1) // Or assert that they remain stable composeTestRule.onNodeWithTag("counter_title") .assertStable() // asserts recompositions = 0 }
