xk6-oauth-pkce

xk6-oauth-pkce is a k6 extension provides the capability to generate OAuth PKCE code verifier and code challenge.

Build

To build a k6 binary with this extension, first ensure you have the prerequisites:

Then:

  1. Download xk6:
$ go install go.k6.io/xk6/cmd/xk6@latest
  1. Build the k6 binary:
$ xk6 build --with github.com/frankhefeng/xk6-oauth-pkce@latest

Example

import pkce from "k6/x/oauth-pkce";

export default function () {
  const verifier = pkce.create("S256");
  console.log(verifier);
  console.log(verifier.verifier);
  console.log(verifier.challenge);
}

Result output:
