react-session-persist v0.0.3

React Session Persist :key: :floppy_disk:

Keep your session sync with your storage and React components.

LIVE EXAMPLE

Installation

yarn: yarn add react-session-persist

npm: npm install react-session-persist --save

Usage

• Wrap your app with the Session component

import { render } from 'react-dom';
import Session from 'react-session-persist';

render(
  <Session>
    <App />
  </Session>,
  document.getElementById('app')
);

• Use the hook to get and handle the session inside React components

import React from 'react';
import { useSession } from 'react-session-persist';

const MyComponent = () => {
  const { authenticated, saveSession } = useSession();
  
  const login = () => {
    saveSession({ token: '123' });
  }
  
  if (authenticated) {
    return <p>User logged in!</p>
  }
  
  return <button onClick={login}>LOG IN</button>
}

• Use the API to handle the session anywhere

import { saveSession } from 'react-session-persist';

const loginUser = (user) => {
  const session = await loginRequest(user);
  await saveSession(session);
}

Session

This component wraps the app to keep the internal session state in sync with the storage.

Props

useSession hook

The hook consumes the session data and methods that the Session component provides through the context.

{
  session, // object with session data
  authenticated, // boolean flag to check if the user is authenticated
  user, // optional object with user data
  saveSession, // promise to save the session
  removeSession, // promise to remove the session
  saveUser, // promise to save optional user data
  loadDataFromStorage // get data directly from the storage
} = useSession()

API

getSession() : object

Returns the current session if exists. Otherwise, it returns undefined.

Example:

import { getSession } from 'react-session-persist';

const session = await getSession();

saveSession(session: object): Promise

Saves the session in the storage and React state. Also, it updates the authenticated flag to true.

removeSession(): Promise

Removes the session from the stores and React state. Also, it updates the authenticated flag to false.

getUser() : object

Returns the optional user data if exists. Otherwise, it returns undefined.

saveUser(user: object): Promise

Saves optional user data (user's name, email, etc) in the storage and React state. Also, it updates the authenticated flag to true.

getAuthenticated(): boolean

Returns a boolean flag that is true if there is a session in the storage.

loadDataFromStorage(): Promise\<object>

Gets the data directly from the storage.

Custom Storage

You can create your own storage just providing an object with 3 methods:

const storage = {
  getItem(key: string): Promise? or object,
  setItem(key: string, data: object): Promise? or void,
  removeItem(key: string): Promise? or void
}

Each method could return a promise or value. If a method returns a promise the storage is consider an async storage.

By default react-redux-persist uses the cache storage.

Async Storage

Check out the async example to use another storage, this example uses localForage.
