Change hex i binary file, simple in python & .net but impossible in electron?


Is it possible in some simple way to open a binary file <20 MB and find a specific hex string and change it and save to the file. A simple game patcher thats works on osx/win.

This is very easy in .net and python but impossible or really hard in electron?


Electron relies on Node for its standard library. You may want to search StackOverflow for things tagged with “node.js” to help with questions like this. For example:


Yep, in a browser you’d use a typed array but in Node you’d use a Buffer object. Buffers can easily convert between binary and hex.
