How to access payload's iss on 1.0.0 on validateJwt() ?

Hello, im new and not used to this library, and im trying to port from djwt 0.9.0 to 1.0.0.

On 0.9.0 i could use validateJwt to get the payload and therefore the iss data stored there as the following:

const data = await validateJwt(
    jwt,
    secret,
    { isThrowing: false},
  );

console.log(data.payload.iss);

but now i can’t, and i can’t find any updated example on the docs.

How can i access the iss data from a decripted jwt token on 1.0.0? Sorry for any inconvenience.

Best regards!

Hi @Frenzoid It seems like the validateJwt function had breaking changes rom 0.9.0 to 1.0.0.

Instead of { isThrowing: false} you now need to specify the algorithm { algorithm: "HS256" }

As the documentation states “The function validateJwt returns a promise. This promise resolves to an object with a union type where the boolean property isValid serves as discriminant.” This means you need to check if the JWT is valid to get access to the payload.

const data = await validateJwt(
    jwt,
    secret,
    { algorithm: "HS256" },
  );

if (data.isValid) {
    console.log(data.payload.iss);
}

Have a look at issue #25. The suggested solution should fix your problem, too.
