get-nonce

just returns a nonce (number used once). No batteries included in those 46 bytes of this library.


  • ✅ build in webpack support via __webpack_nonce__

API

  • getNonce(): string|undefined - returns the current nonce
  • setNonce(newValue) - set's nonce value

Why?

Why we need a library to access __webpack_nonce__? Abstractions!

"I", as a library author, don't want to "predict" the platform "you" going to use. "I", as well, want an easier way to test and control nonce value.

Like - nonce is supported out of the box only by webpack, what you are going to do?

This is why this "man-in-the-middle" was created. Yep, think about left-pad :)

Webpack

https://webpack.js.org/guides/csp/

To activate the feature set a webpack_nonce variable needs to be included in your entry script.

__webpack_nonce__ = uuid(); // for example

Without webpack __webpack_nonce__ is actually just a global variable, which makes it actually bundler independent, however "other bundlers" are able to replicate it only setting it as a global variable (as here in tests) which violates a "secure" nature of nonce.

get-nonce is not global.
