Decompile Node.js 22 .jsc Files
Node.js 22 runs on the V8 12.4 line. JSC Decompiler reads the V8 build straight from the bytecode header and turns compiled .jsc files back into readable JavaScript — no matching runtime required.
Bytecode fingerprint
Every .jsc file opens with a 4-byte little-endian magic header that identifies the V8 code-cache format. Node.js 22 files sit on the V8 12.4 line, paired with Electron 28–32 (V8 12.x).

Upload at jscdecompiler.com
Drag and drop your Node.js 22 .jsc file into the web app. Nothing to install.
Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 12.4 deserializer automatically — you never pick a version by hand.

Node.js 22 version notes
- Node 22 launched on V8 12.4 with the 0xC0DE0628 magic (0xC0DE062E is an alternate build); it pairs with Electron 28–32 on the V8 12.x line.
- Later Node 22 patch releases (22.16+) bumped the bundled V8 to the 13.6 line, which carries a different magic (0xC0DE0692) — the decompiler routes each file by its own header.
- Node 22 is the current active LTS, so it is the most common source of fresh .jsc files.
Node.js 22 decompilation FAQ
What V8 version does Node 22 use?
Node 22 launched on V8 12.4. Note that Node 22.16 and later moved to the V8 13.6 line, so confirm with the file header.
Why do two Node 22 files show different V8 versions?
Node 22's bundled V8 changed across patch releases (12.4 early, 13.6 from 22.16). Each .jsc records the V8 build that wrote it.
How is a Node 22 .jsc decompiled?
Upload it; the 0xC0DE0628 or 0xC0DE0692 header selects the matching V8 deserializer automatically.
