jwt-decode

jwt-decode is a small browser library that helps decoding JWTs token which are Base64Url encoded.

IMPORTANT: This library doesn't validate the token, any well formed JWT can be decoded. You should validate the token in your server-side logic by using something like express-jwt, koa-jwt, Owin Bearer JWT, etc.

Installation

Install with npm, bower, or downloading from the build directory of this repository.

Use with AMD, browserify or just include with an script tag.

Usage

var token = 'eyJ0eXAiO.../// jwt token';
 
var decoded = jwt_decode(token);
console.log(decoded);
 
/* prints:
 * { foo: "bar",
 *   exp: 1393286893,
 *   iat: 1393268893  }
 */

Note: A falsy token will throw an error.

Can also be used with browserify or webpack by doing npm install jwt-decode and requiring:

var jwtDecode = require('jwt-decode');
