From b87ef8cc4718e6f9d5880f8ca78cba4d28a9c08b Mon Sep 17 00:00:00 2001 From: Ben Williams Date: Thu, 18 Dec 2025 23:03:47 -0800 Subject: [PATCH 01/10] Add NAPI-RS pattern support for native module loaders MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements test-driven development support for NAPI-RS auto-generated loaders used by packages like libsql-js. Adds detection and rewriting of: - join(__dirname, 'xxx.node') path patterns (Pattern 6/6b) - require('@scope/package-name') for platform-specific npm packages (Pattern 7) Includes 13 comprehensive test cases covering real-world scenarios. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 --- src/index.ts | 378 ++++++++++++++++++++++++--- test/napi-rs.test.ts | 603 +++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 941 insertions(+), 40 deletions(-) create mode 100644 test/napi-rs.test.ts diff --git a/src/index.ts b/src/index.ts index 464460c..19e604f 100644 --- a/src/index.ts +++ b/src/index.ts @@ -348,6 +348,70 @@ export default function nativeFilePlugin( return null;
