From 752cc830147d9f348442ab12f1a34d0e7aea723d Mon Sep 17 00:00:00 2001 From: Ravi Jayaramappa Date: Mon, 10 Jun 2024 17:16:22 -0700 Subject: [PATCH] feat: expose the registered component class as a const declaration to allow hmr hooks for class @W-15890472 (#4271) * feat: export registered component class via an identifier this allow swapComponent() hooks to be placed * test: update snapshot in packages/@lwc/babel-plugin-component/src/__tests__/ * fix: ignore two non-component swap calls * fix: remove lwc-platform as a downstream dependency * fix: apply class id transformation across the board, no need for APIVersioning * fix: address feedback * fix: check exception message --- .nucleus.yaml | 1 - .../expected.js | 5 +++-- .../expected.js | 5 +++-- .../expected.js | 5 +++--
