Decompile Node.js 10 .jsc Files
Node.js 10 runs on the V8 6.x 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 10 files sit on the V8 6.x line, paired with Electron 4–6 (legacy).
No single magic is pinned for Node.js 10. The decompiler reads the exact V8 version string from the file header instead. Not sure what you have? Analyze the header.
How to decompile a Node.js 10 .jsc file
Upload at jscdecompiler.com
Drag and drop your Node.js 10 .jsc file into the web app. Nothing to install.
Auto-detect the version
JSC Decompiler reads the magic header and selects the V8 6.x deserializer automatically — you never pick a version by hand.

Node.js 10 version notes
- Node 10 tracked the V8 6.x line for its whole lifetime (V8 6.6 at launch through 6.8), sharing the pre-2018 SharedFunctionInfo code-cache layout with Node 8.
- Node 10 reached end-of-life on 2021-04-30; surviving .jsc files are typically legacy bytenode bundles.
- The V8 6.x deserializer rejects caches written by any newer line, so a Node 10 file cannot be re-run on a modern runtime to recover its source.
Node.js 10 decompilation FAQ
Which V8 version is in Node 10?
Node 10 uses the V8 6.x line (6.6 to 6.8). The decompiler reads the exact build from the header.
Is Node 10 still supported by the decompiler?
Yes. JSC Decompiler handles legacy Node 10 .jsc files even though Node 10 itself is end-of-life.
