Simple JWT authentication

Simple JWT authentication allows you to authenticate user on client side based on provided JSON Web Token.

Installation

Install with npm

Run npm install simple-front-jwt-auth to install the library

Usage

• To login user use handleLogin method

import { handleLogin, setLoginCallback } from "simple-front-jwt-auth";

// optionally you can set callback after login
setLoginCallback(() => {
    // do something
});

// login user with token and set token expiration in seconds
handleLogin(token, 3600);

• To auto login user use checkAutologin method. User will be authenticated only if all the required data is available and the token has not expired. Otherwise user will be logged out

import { checkAutologin, setAutologinCallback } from "simple-front-jwt-auth";

// optionally you can set callback after auto login
setAutologinCallback(() => {
    // do something
});

// check if user should be authenticated then log in or log out user
checkAutologin();

• To logout user use handleLogout method

import { handleLogout, setLogoutCallback } from "simple-front-jwt-auth";

// optionally you can set callback after logout
setLogoutCallback(() => {
    // do something
});

// logout user
handleLogout();

• To get user use getUser method. This method returns user if user is authenticated otherwise null

import { getUser } from "simple-front-jwt-auth";

// get user
const user = getUser();
