Middleware implementation of JWT for Lux.
This module lets you authenticate HTTP requests using JWT tokens in your Lux applications. JWTs are typically used to protect (stateless) API endpoints.
$ npm i --save lux-jwt
The JWT authentication middleware authenticates callers using a JWT.
If the token is valid, request.user will be set with the JSON object decoded
to be used by later middleware for authorization and access control.
An example usage of using lux-jwt is shown below.
Secret can also be an Array of multiple valid secrets. A good use case for this is when you use automatically refreshed secrets. This way the previous secret is still valid so the token isn't immediately invalidated when the secret is refreshed. See Heroku Secure Key for more information.
import {Controller} from 'lux-framework';
import jwt from 'lux-jwt';
import unless from 'lux-unless';
class ApplicationController extends Controller {
beforeAction = [
jwt({secret: 'shhhhhhared-secret'})
];
}lux-unless can be used to keep certain endpoints from being authorized by lux-jwt.
import {Controller} from 'lux-framework';
import jwt from 'lux-jwt';
import unless from 'lux-unless';
class ApplicationController extends Controller {
beforeAction = [
unless({path: ['/users/login']}, jwt({secret: 'shhhhhhared-secret'}))
];
}This module also exposes the jsonwebtoken API. Currently this means the following functions are exposed:
sign(payload, secretOrPrivateKey, options)- Create and sign a JWT.verify(token, secretOrPublicKey, [options])- Verify whether or not the passed JWT is valid.decode(token, [options])- Decode the contents of the JWT.
For detailed documentation on these functions please refer to the jsonwebtoken README.
import {sign, verify, decode} from 'lux-jwt'An object containing the following options must be passed:
secret- A string or buffer containing either the secret for HMAC algorithms, or the PEM encoded public key for RSA and ECDSA. Can also be an array with multiple valid secrets.requestProperty(optional) - The key on which the payload of the JWT will be made available.isRevoked(request, decodedAccessToken)(optional) - A function returning whether or not the token was revoked.audience(optional) - The expected audience (aud) to be present in the token.issuer(optional) - The expected issuer (iss) of the token.clockTolerance(optional) - Number of seconds to tolerate when checking the nbf and exp claims, to deal with small clock differences among different servers.algorithms(optional) - A list of strings with the names of the allowed algorithms. For instance,["HS256", "HS384"].
- jsonwebtoken — JSON Web Token sign and verification.
- lux-unless - Conditionally skip a middleware.
