What is a JSC file?

A JSC file is a JavaScript (.JS) file that has been compiled by the bytenode package for Node.js. It contains JavaScript source code that has been translated from plain text to bytecode. Compiling a JS file to a JSC file allows developers to obscure the source code the JS file contains (preventing others from copying or stealing it).

More Information

Node.js is an open-source JavaScript runtime environment, used to run JavaScript programs on a server. Bytecode is a Node.js package, which developers can add to Node.js and use to compile their program's JS files to JSC files.

Primarily, compiling a JS file to a JSC file is meant to prevent app users and other developers from examining, and potentially stealing or altering, the app's source code. For example, a developer creating a browser-based video game using Node.js may choose to compile the game's JS files to JSC files, to prevent other developers from copying their game's logic.

NOTE: Bytenode also works with Electron, a JavaScript desktop application framework that uses Node.js.

How to open a JSC file

You can use bytenode (multiplatform) to run the compiled script a JSC file contains. To do so, enter the following command:

bytenode --run YourFile.jsc

For complete instructions on how to create and use JSC files with bytenode, refer to bytenode's documentation (linked below).
