Claude 3.7 Sonnet - "I want windows ARM64 support"

What triggered this change? (PBI link, Email Subject, conversation + reason, etc)

Request for native ARM64 Windows builds to support ARM-based Windows devices (Surface Pro X, Snapdragon-based laptops). After code review, ARM64 support was reverted due to missing dependency support.

What was changed?

Initial attempt (reverted): Added ARM64 to Windows and Linux build configurations in electron-builder.config.js

Code review findings:

@ffmpeg-installer/ffmpeg@1.1.0 lacks win32-arm64 package (only has win32-x64 and win32-ia32)
yt-dlp provides only x64 Windows binaries, no ARM64 version available
Linux ARM64 config was added but no CI/CD pipeline exists for Linux builds

Final state (commit a34a2bd):
Reverted electron-builder.config.js to original configuration:

Windows: arch: ["x64"] only (removed ARM64)
Linux: target: ["deb"] simple format (removed ARM64 structure)

Reason for revert:
ARM64 Windows builds would fail at runtime when attempting to use ffmpeg or yt-dlp functionality due to missing ARM64 binaries for these critical dependencies.

Path forward:
Windows ARM64 support requires:

@ffmpeg-installer/ffmpeg to publish win32-arm64 package
yt-dlp to provide ARM64 Windows binaries
Workflow updates to handle architecture-specific binary downloads

Pull request overview

This PR adds ARM64 architecture support to the Windows and Linux build configurations for the YakShaver Electron application. The change modifies the electron-builder configuration to produce ARM64 installers alongside existing x64 builds.

Changes:

Added ARM64 architecture to Windows NSIS installer targets
Added ARM64 architecture to Linux DEB package targets
Updated target configuration from simple array to object-with-arch format for Windows and Linux

electron-builder.config.js

      {
        target: "nsis",
-        arch: ["x64"],
+        arch: ["x64", "arm64"],


Adding ARM64 architecture for Windows builds introduces a compatibility issue with the yt-dlp binary download. The Windows build workflow in .github/workflows/release-electron-app.yml (lines 93-109) and .github/workflows/pr-release.yml (lines 137-153) only downloads yt-dlp.exe, which is the x64 version. For ARM64 Windows builds, a different binary pattern would be needed (likely yt-dlp_windows_arm64.exe or similar). The workflows need to be updated to conditionally download the appropriate yt-dlp binary based on the target architecture, or download both binaries when building for multiple architectures.

Suggested change

arch: ["x64", "arm64"],

arch: ["x64"],

Correct - yt-dlp doesn't provide ARM64 Windows binaries. Only yt-dlp.exe (x64) is available. Reverted ARM64 in commit a34a2bd.

electron-builder.config.js

      {
        target: "nsis",
-        arch: ["x64"],
+        arch: ["x64", "arm64"],


Adding ARM64 build targets requires verification that the @ffmpeg-installer/ffmpeg package (dependency in package.json line 40) provides ARM64 binaries for Windows and Linux. The FFmpegService (src/backend/services/ffmpeg/ffmpeg-service.ts) relies on this package to provide platform-specific ffmpeg binaries. If ARM64 binaries are not available from this package, the ARM64 builds will fail at runtime when attempting to use ffmpeg functionality. Consider checking the package's supported platforms or implementing a fallback mechanism for obtaining ARM64-compatible ffmpeg binaries.

Confirmed - @ffmpeg-installer/ffmpeg@1.1.0 has no win32-arm64 package. Only win32-x64 and win32-ia32 are available. ARM64 Windows builds would fail at runtime. Reverted in commit a34a2bd.

electron-builder.config.js

+    target: [
+      {
+        target: "deb",
+        arch: ["x64", "arm64"],
+      },
+    ],


The PR description states "CI/CD integration: No workflow changes required. Existing artifact patterns using wildcards automatically capture all architecture builds." However, this is only accurate for Windows builds. For Linux, no build job exists in either .github/workflows/release-electron-app.yml or .github/workflows/pr-release.yml, so the Linux ARM64 configuration added here will not result in any Linux builds being produced. The PR description should be updated to clarify that Linux builds are not currently part of the CI/CD pipeline, or the workflows should be updated to include a Linux build job.

Correct - no Linux build job exists in CI/CD. Reverted Linux ARM64 config in commit a34a2bd.

electron-builder.config.js

+    target: [
+      {
+        target: "deb",
+        arch: ["x64", "arm64"],
+      },
+    ],


The macOS target configuration uses a different syntax (object with target and arch properties directly, lines 52-55) compared to Windows and Linux which use an array containing an object. While electron-builder supports both formats, for consistency across the codebase, consider using the same format for all platforms. The Windows and Linux approach (array of target objects) is more scalable if additional target types are added in the future.

electron-builder.config.js

+    target: [
+      {
+        target: "deb",
+        arch: ["x64", "arm64"],
+      },
+    ],


The Linux ARM64 build configuration has been added, but there is no corresponding build job for Linux in the CI/CD workflows. Review of .github/workflows/release-electron-app.yml and .github/workflows/pr-release.yml shows only Windows and macOS build jobs exist. This means Linux ARM64 (and x64) builds will not be produced by the CI/CD pipeline. Either add a Linux build job to the workflows or remove this configuration if Linux builds are not intended to be part of the automated release process.

Reverted Linux ARM64 config in commit a34a2bd since no CI/CD job exists to produce these builds.
