RunKit +

Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including maximize with all npm packages installed. Try it out:

maximize lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

// require("maximize/[??]")

maximize v0.0.1

Unobfuscate and beautify obfuscated/minified JavaScript code with source maps

Maximize - Deobfuscate and beautify JavaScript code with source maps

Maximize will deobfuscate and beautify minified code using source maps. Source maps map compiled code back to the original code, including mangled to original function and variable names. JS Beautifier is used under the hood for beautifying.

This program will fail if source maps are not provided and available. Use JS Beautifier directly for beautifying code without transforming variable and function names.

As an example, see the minified script and the generated maximized script from


npm install -g maximize


usage: maximize.js [-h] [-b BEAUTIFY_OPTS] url

Deobfuscate and beautify JavaScript code with source maps

  -b BEAUTIFY_OPTS, --beautify-opts BEAUTIFY_OPTS
                        JS Beautifier options in JSON format
