🌐 Web query:
ffi-rs 1.3.7 package.json source build FreeBSD @yuuang/ffi-rs
💡 Result:
For **`ffi-rs@1.3.7`**, the published `package.json` shows:
- **No FreeBSD target** in its listed N-API triples or optional platform dependencies.
- Build scripts include `build` (`node scripts/build.js`) and `build:c` (`node scripts/compile.js`).
- Platform binaries are supplied as optional `@yuuang/ffi-rs-*` dependencies; the listed targets cover macOS, Linux, Windows, and Android—not FreeBSD. ([github.com](https://github.com/zhangyuang/node-ffi-rs/blob/master/package.json))
So the manifest does **not establish a supported FreeBSD prebuilt binary or a FreeBSD build path**. It doesn’t rule out manually compiling the source on FreeBSD; that would need verification against the version’s build scripts and native source. The GitHub page inspected is `master`, though it displays version 1.3.7; it is not a version-pinned source view. ([github.com](https://github.com/zhangyuang/node-ffi-rs/blob/master/package.json))

🌐 Web query:
ffi-rs 1.3.7 package.json index.js @yuuang FreeBSD native package
💡 Result:
**No—`ffi-rs` 1.3.7 does not list a FreeBSD native package.** Its `package.json` declares platform-specific `@yuuang/ffi-rs-*` optional dependencies for macOS, Linux, Windows, and Android, but none for FreeBSD. Its N-API target list likewise has no FreeBSD target. ([github.com](https://github.com/zhangyuang/node-ffi-rs/blob/master/package.json))
That means the published package does not provide a prebuilt FreeBSD binding. Whether it can be built or made to work on FreeBSD by other means isn’t established by these package files.

Provide a FreeBSD ffi-rs build path before enabling FreeBSD.
The lockfile resolves ffi-rs@1.3.7, but it has no FreeBSD native package. fff-node imports ffi-rs, while FFF_C_LIB only selects the separate libfff_c file. The documented fff_c source-build workaround therefore does not install the required FreeBSD FFI binding. Add and document a supported ffi-rs FreeBSD build/package path, or remove "freebsd" from os until it exists.

[triage-bot] NO CHANGE: keeping freebsd in os.
ffi-rs has no FreeBSD prebuilt. That is true and already documented in packages/fff-node/README.md. But the ffi-rs loader already handles a source-built binding (ffi-rs/index.js:145-154 loads a local ffi-rs.freebsd-x64.node). The reporter in #918 runs exactly that setup. If freebsd comes out of os, npm rejects the install with EBADPLATFORM, and the issue is about removing exactly that block.
Caveat for @dmtrKovalenko: ffi-rs throws Unsupported architecture on FreeBSD: arm64, so in practice only freebsd-x64 works. Not fixable on fff side.

Closes #918
Root cause
packages/fff-node/package.json:32-37leavesfreebsdout ofos.getTriple()throwsUnsupported platform: freebsd(packages/fff-node/src/platform.ts:24).resolveFromNpmPackage()calls it outside itstry(packages/fff-node/src/binary.ts:72), sofindBinary()throws before the dev-build fallback. There is also no override. Result: alibfff_c.sobuilt from source can't be loaded from an npm install. #904 fixed exactly this, but only for fff-bun.Fix
Same change as #904, applied to fff-node:
