import { jwtWriter } from "@deanrih/ts-lib-jwt";

const secretKey = "$up3r$3cretK3y7h@7@7l34$t256b1ts";
const tokenResult = jwtWriter({
	iss: "/issuer",

	aud: ["/audience/name-1", "/audience/name-2"],
	azp: ["/party/name-1"],

	typ: "/authorization",
	cse: "/sign-in/request",

	sub: "user-one-account-id",
}).encode();

if (tokenResult.isErr()) {
	console.error(`Failed to generate token`);
	throw tokenResult.error;
}

const tokenSigned = tokenResult.value.sign(secretKey);

console.log("Token:");
console.log(tokenSigned);

import { jwtReader } from "@deanrih/ts-lib-jwt";

const encodedToken = "...";
const secretKey = "$up3r$3cretK3y7h@7@7l34$t256b1ts";
const decodedResult = jwtReader(encoded).decode();

if (decodedResult.isErr()) {
	console.error(`Failed to decode token`);
	throw decodedResult.error;
}

const token = decoded.value;
const validateResult = token.validate(secretKey);

if (validateResult.isErr()) {
	console.error(`Failed to validate token`);
	throw validateResult.error;
}

const validatedToken = validateResult.value;
const header = validatedToken.header;
const payload = validatedToken.payload;

console.log("Subject:");
console.log(payload["sub"]);
