jot

hapi JSON Web Token (JWT) authentication plugin

The 'jwt' scheme takes the following options:

Option	Type	Required	Description
secret	string	Yes	Secret key used to compute the signature
algorithms	array		Algorithm(s) allowed to verify tokens. Defaults to ['HS256']. Valid algorithms: ['HS256', 'HS384', 'HS512', 'RS256', 'RS384', 'RS512', 'ES256', 'ES384', 'ES512', 'none']
audience	string		Verify aud claim against this value
cookie	string		Cookie name. Defaults to sid. Works in tandem with hapi-auth-cookie. Must set JWT when the cookie is set. See examples below
issuer	string		Verify iss claim against this value
token	string		Name of the token set in the cookie. Defaults to token
validateFunc	function		Function to validate the decoded token on every request

Note: Storing the token in a cookie is optional, but recommended. You can always send the token in an Authorization header.

/* server.js */
 
 
// Register hapi-auth-cookie
 
server.register(require('hapi-auth-cookie'), (err) => {
 
    server.auth.strategy('session', 'cookie', {
        cookie: 'cookie-name',
        password: 'TheMinimumLengthOfPasswordsIs32!'
    });
});
 
 
// Register jot
 
server.register(require('jot'), (err) => {
 
    server.auth.strategy('jwt', 'jwt', {
        secret: 'ADifferentPasswordAlsoAtLeast32!',
        cookie: 'cookie-name'
    });
 
    server.auth.default({
        strategy: 'jwt',
        scope: ['admin']
    });
});
 
 
/* routes.js */
 
 
// Login route
 
server.route({
    method: 'POST',
    path: '/login',
    config: {
        auth: false,
        handler: (request, reply) => {
 
            // ... validate user credentials, yada yada yada ...
 
            // Set the token inside of the cookie
 
            request.cookieAuth.set(Jwt.sign({
                scope: ['admin']
            }, 'ADifferentPasswordAlsoAtLeast32!', {
                expiresIn: 60 * 60 * 2 // 2 hrs, but can be anything
            }));
 
            reply('ok!');
        }
    }
});
 
 
// Resource
 
server.route({
    method: 'GET',
    path: '/trade-secrets',
    config: {
        handler: (request, reply) => {
 
            // User is already authorized, time to check out those trade secrets
 
            reply('secrets!');
