A very small module to make objects read only. Useful for config objects such as process.ENV or others.

installation

npm install --save read-only-object

usage

Load object

const RO = require("read-only-object")

const config = {
  pass: "1234",
  urls: [
    'http1',
    'http2'
  ]
}

const oRoObj = RO.load(config); // config is now read-only in oRoObj
const oRoObj2 = RO.get(); // will retrieve the loaded config

Value access

console.log(oRoObj.pass) // shows "1234"

oRoObj.a = 1 // Throw an error
oRoObj.urls.push("http3") // throw an error
