Jwt-react-tools NPM

JWT React Tools

React HOC to make usage of JWT extremely fun

Installation

yarn add jwt-xhr-hook

or npm i --save jwt-xhr-hook if you are still using npm

Usage

This package provides a decorator to add isAuthenticated flag and jwtPayload inside component's props and child context

import React, { Component, PropTypes } from 'react';
import JWT from 'jwt-react-tools';


@JWT()
class Main extends Component {

  render() {
    return (
      <div>foo</div>
    );
  }
}

This will provide isAuthenticated flag and jwtPayload object from token stored in Local Storage by key 'jwt'. If you want to load JWT from another key pass key name through argument.

import React, { Component, PropTypes } from 'react';
import JWT from 'jwt-react-tools';


@JWT('customKey')
class Main extends Component {

  render() {
    return (
      <div>foo</div>
    );
  }
}

Access data inside child context

import React, { PropTypes } from 'react';

const Menu = (props, { isAuthenticated, jwtPayload }) => (
  <nav className={ s.header }>
    <ul>
      <li>
        <IndexLink to="/" activeClassName={ s.active }>JWT</IndexLink>
      </li>
      {isAuthenticated &&
      <li>
        <Link to="/" activeClassName={ s.active }>{jwtPayload.sub}</Link>
      </li>
      }
      {isAuthenticated &&
      <li>
        <Link to="/users" activeClassName={ s.active }>Users</Link>
      </li>
      }
      <li>
        <Link to="/github" activeClassName={ s.active }>GitHub</Link>
      </li>
      {!isAuthenticated &&
      <li>
        <Link to="/sign-in" activeClassName={ s.active }>Sign In</Link>
      </li>
      }
      {!isAuthenticated &&
      <li>
        <Link to="/sign-up" activeClassName={ s.active }>Sign Up</Link>
      </li>
      }
      {isAuthenticated &&
      <li className={ s.pullRight }>
        <button onClick={ onLogout }>Logout</button>
      </li>
      }
    </ul>
  </nav>
);

Menu.contextTypes = {
  isAuthenticated: PropTypes.bool,
  jwtPayload: PropTypes.object,
};
