Build script only targeted x64 architectures, causing M4 MacBook Air users to hit resource path 'rpg-mcp-server-aarch64-apple-darwin' doesn't exist when integrating with Tauri frontend.

Changes

  • esbuild.config.mjs: Added node20-macos-arm64 to pkg targets and darwin-arm64 to platform mappings. Fixed deployment paths from src-tauri/ to ../src-tauri/ (relative from rpg-mcp repo to frontend). Added separate Intel/ARM64 instructions.

  • README.md: Split macOS sections by architecture (Intel vs Apple Silicon). Added uname -m detection helper. Clarified Quest Keeper AI integration requires relative paths.

  • tests/build/build-config.test.ts: Validates all 4 platforms (win-x64, macos-x64, macos-arm64, linux-x64), prebuild URLs, and Tauri binary name mappings.

  • .gitignore: Changed dist/ and build/ to /dist/ and /build/ to allow tracking tests/build/ directory.

Build Output

bin/
├── rpg-mcp-macos-arm64                # Maps to rpg-mcp-server-aarch64-apple-darwin
├── rpg-mcp-macos                      # Maps to rpg-mcp-server-x86_64-apple-darwin

└── better_sqlite3-macos.node

M4 Mac users can now build and deploy ARM64 binaries with correct Tauri target names.

<issue_description>After installation of dependencies and building of binaries (btw many of the commands on the homepage seem no longer up to date based on paths and filenames), I get this error:

It's unclear where it's looking for that file. After building binaries I got this output:

🎉 Build complete! Files in bin/:

better_sqlite3-linux.node 1.99 MB
better_sqlite3-macos.node 1.82 MB
better_sqlite3-win.node 1.81 MB
better_sqlite3.node 1.81 MB
rpg-mcp-linux 57.95 MB
rpg-mcp-macos 52.26 MB
rpg-mcp-win.exe 44.68 MB

📦 Deployment instructions:

For Tauri (Windows):
copy bin\rpg-mcp-win.exe src-tauri\binaries\rpg-mcp-server-x86_64-pc-windows-msvc.exe
copy bin\better_sqlite3.node src-tauri\binaries\

For Tauri (macOS):
cp bin/rpg-mcp-macos src-tauri/binaries/rpg-mcp-server-x86_64-apple-darwin
cp bin/better_sqlite3-macos.node src-tauri/binaries/better_sqlite3.node

For Tauri (Linux):
cp bin/rpg-mcp-linux src-tauri/binaries/rpg-mcp-server-x86_64-unknown-linux-gnu
cp bin/better_sqlite3-linux.node src-tauri/binaries/better_sqlite3.node

Those paths are not correct (it has to be ../src-tauri/

And as you can see there's no aarch64 file. Also I had to manually create the binaries directory under src-tauri as it wasn't there. I tried renaming the x86_64-apple-darwin to aarch64 (which I wouldn't suspect would work) and it gave me the asme error of not being able to find it, so I don't even know if it's looking in the right place.</issue_description>
