Unfreeze

This module simply recursively unfreezes an object that has been frozen using Object.freeze().

But Why?

I wrote it at a time when I wanted to use S3 config values with aws-sdk module.

I was using the amazing config module to manage my configs. If you have used config you would know that it freezes the config object and aws-sdk throws an error when options are frozen.

I think there are other use cases out there so I will leave this here for your benefit 🌟 !

How to use

const unfreeze = require("unfreeze");

// our object
let obj = {
    a: "first val",
    b:2
}
// update value
obj.a = "1st value";
// log
console.log("unfrozen object", obj);

// now freeze object
Object.freeze(obj);
// updating a value should fail
obj.b = "two";
// log
console.log("frozen object", obj);

// now unfreeze object
obj = unfreeze(obj);
// updating a value should fail
obj.b = "two";
// log
console.log("unfrozen object", obj);

This logs:

unfrozen object { a: '1st value', b: 2 }
frozen object { a: '1st value', b: 2 }
unfrozen object { a: '1st value', b: 'two' }

Note: This example uses a simple object. But unfreeze works well even with deeply nested objects!

Enjoy!
