hapi-auth-jwt

hapi JSON Web Token (JWT) authentication plugin

JSON Web Token authentication requires verifying a signed token. The 'jwt' scheme takes the following options:

• key - (required) The private key the token was signed with.
• validateFunc - (optional) validation and user lookup function with the signature function(token, callback) where:
  • token - the verified and decoded jwt token
  • callback - a callback function with the signature function(err, isValid, credentials) where:
    • err - an internal error.
    • isValid - true if the token was valid otherwise false.
    • credentials - a credentials object passed back to the application in request.auth.credentials. Typically, credentials are only included when isValid is true, but there are cases when the application needs to know who tried to authenticate even when it fails (e.g. with authentication mode 'try').

See the example folder for an executable example.

var accounts = {
    123: {
      id: 123,
      user: 'john',
      name: 'John Doe',
      scope: ['a', 'b']
    }
};

var validate = function (decodedToken, callback) {

    var account = accounts[decodedToken.accountID];
    if (!account) {
        return callback(null, false);
    }

    callback(err, isValid, {id: account.id, name: account.name });
};

server.pack.register(require('hapi-auth-jwt'), function (err) {
    var privateKey = 'BbZJjyoXAdr8BUZuiKKARWimKfrSmQ6fv8kZ7OFfc';

    server.auth.strategy('token', 'jwt', { key: privatekey,  validateFunc: validate });
    server.route({ method: 'GET', path: '/', config: { auth: 'token' } });
});
