js-smr

This application uses names from source map to restore original variable names. It does not use original source code, it only relies on source maps. Also the script does not make code more readable - use prettier for that.

Example

It can convert file from this:

function sum(n,o){return n+o}console.log(sum(10,20));

to this:

function sum(lvalue,rvalue){return lvalue+rvalue}console.log(sum(10,20));

For the reference, original code:

function sum(lvalue, rvalue) {
    return lvalue + rvalue;
}
console.log(sum(10, 20));

Local installation & usage

npm i -prod
npm link
js-smr ./patj/to/file.js

Additional tools - ranges.py

This script recreates directories structures for single concatenated JS file, which uses define('/path/to/file', (...) => ...),... concatenation
