Decompile exe file

[ffbboy30]

Hi,

I'm looking to find a solution to decompile an exe file.
With an Hex editor I can see the file start with MZ and contain node.js or java file.
I've tried to decompress with 7zip.
Do you have some idea ? Thanks

I've made a error with my question .
When I compile it not works the same as norma, it works a little bit speeder than my VS code.
That why I'm looking to go back to compare.
If it is not possible I don't care , it's a tiny problem.

I've another question in the exe I've found
"./node_modules/ws/package.json":[58874,1234]
58874 is the offset ?
1234 the size file ?

What that it means ?

I've another question in the exe I've found
"./node_modules/ws/package.json":[58874,1234]

That line represents an entry in the nexe virtual file system manifest (its an implementation detail, the offset in the blob (not the binary itself) and byte length)

nexe/src/fs/bundle.ts

Line 144 in 0c7b942

this.index[name] = existingEntry || [this.offset, size]

At build time your application's dependencies (on the build machine) are combined into an uncompressed blob and appended to the end of a mostly normal node.js binary.

When I compile it not works the same as norma, it works a little bit speeder than my VS code.

The file system calls are likely faster because the reads can share a descriptor as they seek through the blob.

So if the file are listed correctly in the exe , Is possible to go back from the exe to the project to compare the both code if they are the same ?
Thanks

Yes, it's possible. But the methodology for doing so is not documented and subject to break.
