freeze-deep
A fast and type safe recursive (deep) object/array/function freeze
Fast, type safe and tested, it always returns the type and value(s) you've feeded it, frozen if freezable.
const freezeDeep = require('freeze-deep');
const MODEL= freezeDeep({
person: {
name: ''
friends: []
}
});
MODEL.person.name= 'Max';
console.log( MODEL.person.name );
// ''
delete MODEL.person.name;
console.log( MODEL.person );
// { name: '', friends: [] }
MODEL.person.friends[0]= 'Jack';
console.log( MODEL.person.friends[0] );
// undefined
// no runtime error on undefined or null
freezeDeep();
freezeDeep( null );
When using with node.js: npm install --save freeze-deep
in the project root.
To run the tests: npm test
at the cli in the project root.
I am always open for feedback and suggestions on how to improve the code.
