A simple way to freeze JavaScript objects and know of attempted modifications.
Why not just use Object.freeze and Object.isFrozen?
If you use Object.freeze and later set a property on that object, it silently fails unless in strict mode. Also, using this technique gives you the ability to listen for warnings on the warning event.
npm install --save proxy-freeze
object or constructor functionlet obj = {
name: 'jp'
}
let obj2 = proxyFreeze(obj)
obj2.name = 'bob'
process.once('warning', (warning) => {
console.warn(warning.name) // => ProxyFreezeWarning
console.warn(warning.message) // => Trying to set value of property (name) of frozen object.
console.warn(warning.stack)
})
