Write files straight to OS transparent filesystem compression (APFS decmpfs / btrfs / NTFS) in one pass.
Apply the operating system's transparent per-file filesystem compression to a file — smaller on disk, byte-identical on read, decompressed by the kernel at near-native speed. macOS APFS (decmpfs/LZVN), Linux btrfs (zstd→lzo→zlib), Windows NTFS (LZNT1).
This is the Node addon for decmpfs. The
prebuilt native binary ships as an optional dependency per platform
(@decmpfs/<triple>); pnpm installs only the one matching the host.
npm install decmpfs
const { writeDecmpfsFile, copyDecmpfsFile } = require('decmpfs')
// Write bytes straight to an OS-compressed file — one pass, no recompress.
const result = writeDecmpfsFile('data.bin', bytes)
// Compression-preserving copy (clonefile / FICLONE, or recompress).
copyDecmpfsFile('data.bin', 'copy.bin')
See the repository for the full API and the Rust crate.
