How to deal with JWT expiration?

First of all, please note that token expiration and revoking are two different things.

  1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
  2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

An Easier Way to Enforce Required Parameters in ES6

An Easier Way to Enforce Required Parameters in ES6

Expands on Handling required parameters in ECMAScript 6 by Axel Rauschmayer.

const throwIfMissing () => { throw new Error('Missing parameter') }
