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:

go build compile and build executable and move it to the destination where you run the command

go install compile and move executable to $GOBIN directory, and cache all non-main packages which imported for the package you installed, it will be used in your next compile if not changed yet.

Redux higher order components

Sometimes we need to share props and behaviour between multiple components/containers. For that we can do a higher order component. Example:

Decorator component

Higher Order Component that will decorate other component:

Redux Selector Pattern

Imagine we have a reducer to control a list of items:

function listOfItems(state: Array<Object> = [], action: Object = {}): Array<Object> {
  switch(action.type) {
    case 'SHOW_ALL_ITEMS':
      return action.data.items
    default:

function mapValues(obj, fn) {
  return Object.keys(obj).reduce((result, key) => {
    result[key] = fn(obj[key], key);
    return result;
  }, {});
}

function pick(obj, fn) {
  return Object.keys(obj).reduce((result, key) => {
    if (fn(obj[key])) {
