Hapi Auth using JSON Web Tokens (JWT)

The authentication scheme/plugin for Hapi.js apps using JSON Web Tokens

This node.js module (Hapi plugin) lets you use JSON Web Tokens (JWTs) for authentication in your Hapi.js web application.

If you are totally new to JWTs, we wrote an introductory post explaining the concepts & benefits: https://github.com/dwyl/learn-json-web-tokens

If you (or anyone on your team) are unfamiliar with Hapi.js we have a quick guide for that too: https://github.com/dwyl/learn-hapi

Usage

We tried to make this plugin as user (developer) friendly as possible, but if anything is unclear, please submit any questions as issues on GitHub: https://github.com/dwyl/hapi-auth-jwt2/issues

Install from NPM

npm install hapi-auth-jwt2 --save

Example

This basic usage example should help you get started:

const Hapi = require('@hapi/hapi');

const people = { // our "users database"
    1: {
      id: 1,
      name: 'Jen Jones'
    }
};

// bring your own validation function
const validate = async function (decoded, request, h) {

    // do your checks to see if the person is valid
    if (!people[decoded.id]) {
      return { isValid: false };
    }
    else {
      return { isValid: true };
    }
};

const init = async () => {
  const server = new Hapi.server({ port: 8000 });
  // include our module here ↓↓, for example, require('hapi-auth-jwt2')
  await server.register(require('../lib'));
  server.auth.strategy('jwt', 'jwt',
  { key: 'NeverShareYourSecret', // Never Share your secret key
    validate  // validate function defined above
  });

  server.auth.default('jwt');

  server.route([
    {
      method: "GET", path: "/", config: { auth: false },
      handler: function(request, h) {
        return {text: 'Token not required'};
      }
    },
    {
      method: 'GET', path: '/restricted', config: { auth: 'jwt' },
      handler: function(request, h) {
        const response = h.response({text: 'You used a Token!'});
        response.header("Authorization", request.headers.authorization);
        return response;
      }
    }
  ]);
  await server.start();
  return server;
}
init().then(server => {
  console.log('Server running at:', server.info.uri);
})
.catch(err => {
  console.log(err);
});

Quick Demo

Open your terminal and clone this repo:

git clone https://github.com/dwyl/hapi-auth-jwt2.git && cd hapi-auth-jwt2

Run the server with:

npm install && node example/server.js

Now (in a different terminal window) use cURL to access the two routes:

No Token Required

curl -v http://localhost:8000/

Token Required

Try to access the /restricted content without supplying a Token (expect to see a 401 error):

curl -v http://localhost:8000/restricted

or visit: http://localhost:8000/restricted in your web browser. (both requests will be blocked and return a 401 Unauthorized error)

Now access the url using the following format: curl -H "Authorization: <TOKEN>" http://localhost:8000/restricted

A here's a valid token you can use (copy-paste this command):

curl -v -H "Authorization: eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6MSwibmFtZSI6IkFudGhvbnkgVmFsaWQgVXNlciIsImlhdCI6MTQyNTQ3MzUzNX0.KA68l60mjiC8EXaC2odnjFwdIDxE__iDu5RwLdN1F2A" \
http://localhost:8000/restricted

or visit this url in your browser (passing the token in url):

http://localhost:8000/restricted?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6MSwibmFtZSI6IkFudGhvbnkgVmFsaWQgVXNlciIsImlhdCI6MTQyNTQ3MzUzNX0.KA68l60mjiC8EXaC2odnjFwdIDxE__iDu5RwLdN1F2A

That's it.

Now write your own validate with what ever checks you want to perform on the decoded token before allowing the visitor to proceed.

Documentation

key - (required - unless you have a customVerify function) the secret key (or array of potential keys) used to check the signature of the token or a key lookup function with signature async function(decoded) where:
- decoded - the decoded but unverified JWT received from client
- Returns an object { key, extraInfo } where:
  - key - the secret key (or array of keys to try)
  - extraInfo - (optional) any additional information that you would like to use in validate which can be accessed via request.plugins['hapi-auth-jwt2'].extraInfo
- Throws a Boom error when key lookup fails. Refer to this example implementation and its associated test for a working example.
validate - (required) the function which is run once the Token has been decoded with signature async function(decoded, request, h) where:
- decoded - (required) is the decoded and verified JWT received in the request
- request - (required) is the original request received from the client
- h - (required) the response toolkit.
- Returns an object { isValid, credentials, response } where:
  - isValid - true if the JWT was valid, otherwise false.
  - credentials - (optional) alternative credentials to be set instead of decoded.
  - response - (optional) If provided will be used immediately as a takeover response.
  - errorMessage - (optional defaults to 'Invalid credentials') - the error message raised to Boom if the token is invalid (passed to errorFunc as errorContext.message)

Optional Parameters

verifyOptions - (optional defaults to none) settings to define how tokens are verified by the jsonwebtoken library
- ignoreExpiration - ignore expired tokens
- audience - do not enforce token audience
- issuer - do not require the issuer to be valid
- algorithms - list of allowed algorithms
responseFunc - (optional) function called to decorate the response with authentication headers before the response headers or payload is written where:
- request - the request object.
- h- the response toolkit.
errorFunc - (optional defaults to raising the error requested) function called when an error has been raised. It provides an extension point to allow the host the ability to customise the error messages returned. Passed in object follows the following schema:
- errorContext - the error object.
  - errorContext.errorType - required the Boom method to call (eg. unauthorized)
  - errorContext.message - required the message passed into the Boom method call
  - errorContext.schema - the schema passed into the Boom method call
  - errorContext.attributes - the attributes passed into the Boom method call
  - errorContext.error - the exception thrown (optional, if available)
  - errorContext.token - the JWT provided, in string form (optional, if available)
  - The function is expected to return the modified errorContext with all above non-optional fields defined.
- request - the request object.
- h- the response toolkit.
urlKey - (optional defaults to 'token') - if you prefer to pass your token via url, simply add a token url parameter to your request or use a custom parameter by setting urlKey. To disable the url parameter set urlKey to false or ''.
cookieKey - (optional defaults to 'token') - if you prefer to set your own cookie key or your project has a cookie called 'token' for another purpose, you can set a custom key for your cookie by setting options.cookieKey='yourkeyhere'. To disable cookies set cookieKey to false or ''.
headerKey - (optional defaults to 'authorization') - The lowercase name of an HTTP header to read the token from. To disable reading the token from a header, set this to false or ''.
payloadKey - (optional defaults to 'token') - The lowercase name of an HTTP POST body to read the token from. To disable reading the token from a payload, set this to false or ''. Please note, this will not prevent authentication falling through to the payload method unless attemptToExtractTokenInPayload is false
tokenType - (optional defaults to none) - allow custom token type, e.g. Authorization: <tokenType> 12345678.
complete - (optional defaults to false) - set to true to receive the complete token (decoded.header, decoded.payload and decoded.signature) as decoded argument to key lookup and verify callbacks (not validate)
headless - (optional defaults to none) - set to an object containing the header part of the JWT token that should be added to a headless JWT token received. Token's with headers can still be used with this option activated. e.g { alg: 'HS256', typ: 'JWT' }
attemptToExtractTokenInPayload - (optional defaults to false) - set to true to let the authenticate method fall through to the payload method for token extraction
customExtractionFunc - (optional) function called to perform a custom extraction of the JWT where:
- request - the request object.

Useful Features

The encoded JWT (token) is extracted from the request and made available on the request object as request.auth.token, in case you need it later on in the request lifecycle. This feature was requested by @mcortesi in hapi-auth-jwt2/issues/123

Understanding the Request Flow

At the simplest level this is the request flow through a Hapi App using hapi-auth-jwt2:

verifyOptions let you define how to Verify the Tokens (Optional)

example:

server.auth.strategy('jwt', 'jwt', true,
{ key: 'NeverShareYourSecret', // Never Share your secret key
  validate: validate,      // validate function defined above
  verifyOptions: {
    ignoreExpiration: true,    // do not reject expired tokens
    algorithms: [ 'HS256' ]    // specify your secure algorithm
  }
});

Read more about this at: jsonwebtoken verify options

Specify Signing Algorithm (Optional but highly recommended)

For security reasons it is recommended that you specify the allowed algorithms used when signing the tokens:

server.auth.strategy('jwt', 'jwt', true,
{ key: 'YourSuperLongKeyHere', // Never Share your secret key
  validate: validate,      // validate function defined above
  verifyOptions: { algorithms: [ 'HS256' ] }  // only allow HS256 algorithm
});

If you prefer not to use any of these verifyOptions simply do not set them when registering the plugin with your app; they are all optional.

This feature was requested in: issues/29

Using Base64 encoded secret keys

Some authentication services (like Auth0) provide secret keys encoded in base64, To find out if your authentication service is one of these services, please try and experiment with the base64 encoded secret options on the validator at https://jwt.io

If your key is base64 encoded, then for JWT2 to use it you need to convert it to a Buffer. Following is an example of how to do this.

server.auth.strategy('jwt', 'jwt', true,
{ key: Buffer.from('<Your Base64 encoded secret key>', 'base64'), // Never Share your secret key
  validate: validate,      // validate function defined above
  verifyOptions: { algorithms: [ 'HS256' ] }  // only allow HS256 algorithm
});

Authentication Modes

This plugin supports authentication modes on routes.

required - requires JWT to be sent with every request
optional - if no JWT is provided, request will pass with request.auth.isAuthenticated set to false and request.auth.credentials set to null
try - similar to optional, but invalid JWT will pass with request.auth.isAuthenticated set to false and failed credentials provided in request.auth.credentials

Additional notes on keys and key lookup functions

This option to look up a secret key was added to support "multi-tenant" environments. One use case would be companies that white label API services for their customers and cannot use a shared secret key. If the key lookup function needs to use fields from the token header (e.g. x5t header), set option completeToken to true.
The reason why you might want to pass back extraInfo in the callback is because you likely need to do a database call to get the key which also probably returns useful user data. This could save you another call in validate.
The key or value returned by the key lookup function can also be an array of keys to try. Keys will be tried until one of them successfully verifies the signature. The request will only be unauthorized if ALL of the keys fail to verify. This is useful if you want to support multiple valid keys (like continuing to accept a deprecated key while a client switches to a new key).

server.auth.strategy('jwt', 'jwt', true,
{ key: [ 'PrimareSecretKey', 'DeprecatedKeyStillAcceptableForNow' ],
  validate: validate,
  verifyOptions: { algorithms: [ 'HS256' ] }
});

URL (URI) Token

Several people requested the ability pass in JSNOWebTokens in the requested URL: dwyl/hapi-auth-jwt2/issues/19

Usage

Setup your hapi.js server as described above (no special setup for using JWT tokens in urls)

https://yoursite.co/path?token=your.jsonwebtoken.here

You will need to generate/supply a valid tokens for this to work.

const JWT   = require('jsonwebtoken');
const obj   = { id:123,"name":"Charlie" }; // object/info you want to sign
const token = JWT.sign(obj, secret);
const url   = "/path?token="+token;

What if I want to disable the ability to pass JWTs in via the URL? Set your urlKey to false or ''. (added by @bitcloud: issue #146)

Generating Your Secret Key

@skota asked "How to generate secret key?" in: dwyl/hapi-auth-jwt2/issues/48

There are several options for generating secret keys. The easiest way is to run Node's crypto hash in your terminal:

node -e "console.log(require('crypto').randomBytes(256).toString('base64'));"

and copy the resulting base64 key and use it as your JWT secret.

Want to access the JWT token after validation?

@mcortesi requested the ability to access the (raw) JWT token used for authentication. dwyl/hapi-auth-jwt2/issues/123

You can access the extracted JWT token in your handler or any other function within the request lifecycle with the request.auth.token property.

Note that this is the encoded token, and it's only useful if you want to use to make request to other servers using the user's token.

The decoded version of the token, accessible via request.auth.credentials

Want to send/store your JWT in a Cookie?

@benjaminlees requested the ability to send/receive tokens as cookies: dwyl/hapi-auth-jwt2/issues/55 So we added the ability to optionally send/store your tokens in cookies to simplify building your web app.

To enable cookie support in your application all you need to do is add a few lines to your code:

Cookie Options

Firstly set the options you want to apply to your cookie:

const cookie_options = {
  ttl: 365 * 24 * 60 * 60 * 1000, // expires a year from today
  encoding: 'none',    // we already used JWT to encode
  isSecure: true,      // warm & fuzzy feelings
  isHttpOnly: true,    // prevent client alteration
  clearInvalid: false, // remove invalid cookies
  strictHeader: true   // don't allow violations of RFC 6265
}

Set the Cookie on your `reply`

Then, in your authorisation handler

reply({text: 'You have been authenticated!'})
.header("Authorization", token)        // where token is the JWT
.state("token", token, cookie_options) // set the cookie with options

For a detailed example please see: https://github.com/nelsonic/hapi-auth-jwt2-cookie-example

Frequently Asked Questions (FAQ)

Do I need to include `jsonwebtoken` in my project?

Q: Must I include the jsonwebtoken package in my project [given that hapi-auth-jwt2 plugin already includes it] ? asked in hapi-auth-jwt2/issues/32
A: Yes, you need to manually install the jsonwebtoken node module from NPM with npm install jsonwebtoken --save if you want to sign JWTs in your app. Even though hapi-auth-jwt2 includes it as a dependency your app does not know where to find it in the node_modules tree for your project. Unless you include it via relative path e.g: const JWT = require('./node_modules/hapi-auth-jwt2/node_modules/jsonwebtoken'); we recommend including it in your package.json explicitly as a dependency for your project.

Custom Verification ?

Can we supply a Custom Verification function instead of using the JWT.verify method?
asked by both Marcus Stong & Kevin Stewart in issue #120 and issue #130 respectively. Q: Does this module support custom verification function or disabling verification? A: Yes, it does now! (see: "Advanced Usage" below) the inclusion of a verify gives you complete control over the verification of the incoming JWT.

Can I use `hapi-auth-jwt2` with `glue`

Several people asked us if this plugin is compatible with Hapi's "Server Composer" glue

The answer is Yes! For an example of how to do this, see @avanslaars code example: #151 (comment)

How do I invalidate an existing token?

Asked by @SanderElias in hapi-auth-jwt2/issues/126

We store our JWT-based sessions in a Redis datastore and lookup the session (jti) for the given JWT during the validate (validation function) see: https://github.com/dwyl/hapi-auth-jwt2-example/blob/791b0d3906d4deb256daf23fcf8f5021905abe9e/index.js#L25 This means we can invalidate the session in Redis and then reject a request that uses an "old" or invalid JWT. see: https://github.com/dwyl/hapi-auth-jwt2-example/blob/791b0d3906d4deb256daf23fcf8f5021905abe9e/index.js#L25

How do I set JWT Auth to All Routes?

@abeninskibede asked how to set all routes to use JWT Auth in hapi-auth-jwt2/issues/149

We tend to enable hapi-auth-jwt2 for all routes by setting the default strategy to 'jwt' (so its required for all endpoints) because most of the endpoints in our app require the person/user to be authenticated e.g:

server.auth.strategy('jwt', 'jwt', {
  ...
});
server.auth.default('jwt'); // so JWT auth is required for all routes

When you want a particular route to not require JWT auth you simply set config: { auth: false } e.g:

server.route({
  method: 'GET',
  path: '/login',
  handler: login_handler,  // display login/registration form/page
  options: { auth: false } // don't require people to be logged in to see the login page! (duh!)
});

The best place to *understand* everything about Hapi Auth is in the docs: [https://hapi.dev/tutorials/auth/#default](https://hapi.dev/tutorials/auth/#default) But if you have any questions which are not answered there, feel free to [ask!](https://github.com/dwyl/hapi-auth-jwt2/issues)

How to redirect if a token has expired?

@traducer & @goncalvesr2 both requested how to redirect after failed Auth in hapi-auth-jwt2/issues/161 and hapi-auth-jwt2/issues/148 respectively

The hapi-error lets you easily redirect to any url you define if the Auth check fails (i.e. statusCode 401) see: https://github.com/dwyl/hapi-error#redirectredirecting-to-another-endpoint (code examples there.)

How do I change my token and re-state it without becoming unauthenticated?

For example:

If the request.auth.credentials object initially added to your / endpoint initial was:

{
  userId: 1,
  permission: 'ADMIN'
}

And you want to change the user's permission to SUPER_ADMIN.

Retrieve the initial session object added as a token to /

const session  = request.auth.credentials;

Change the object

session.permission = 'SUPER_ADMIN';

Sign as a JWT token again

const token = JWT.sign(session, process.env.JWT_SECRET);

Reply as usual whilst re-adding the token to your original endpoint /

reply().state('token', token, { path: '/' }).redirect('/wherever');

How do I support users with JS disabled

An issue can arise when supporting users with JavaScript disabled when JWTs are too large to pass on query strings.

With JS disabled, tokens cannot be added to headers by using redirects from OAuth providers in to the consuming service.

Cloud providers will place limitations on URI lengths

OAuth services may not always sit on a sibling subdomain of the protected service negating the use of a secure cookie

The only way to pass a token in this case is to use either an HTML form with the token in a hidden field and a button with instructions for users to press the button if they have JS disabled and some JS that will submit the form automatically if it is enabled

To configure hapi-auth-jwt to support this scenario, you will need to adapt the following sample configuration

server.auth.strategy('jwt', 'jwt', {
  key: 'NeverShareYourSecret',
  // defining our own validate function lets us do something
  // useful/custom with the decodedToken before reply(ing)
  validate: (decoded, request) => true,
  verifyOptions: { algorithms: [ 'HS256' ] }, // only allow HS256 algorithm
  attemptToExtractTokenInPayload: true,
  // using yar as a session cache to store tokens, see: https://github.com/hapijs/yar
  customExtractionFunc: request => {
    if (request.auth && request.auth.token) {
      request.yar.set('token', request.auth.token)
      return request.auth.token;
    }
    const token = request.yar.get('token');
    if (token) {
      return token;
    }
  }
});

The configuration above will still run the normal token extraction attempts for headers, cookies, query string parameters and custom extraction. However, if there is no token successfully extracted, it will attempt to extract one from POST request bodies

As the authentication phase of a HAPI request will apply scope protection before POST bodies are parsed, you will need to also define the route on which you will handle JWTs with no scope applied or the POST requests with JWT payloads will fail when you globally apply scope as part of your application

server.route([
      {
        method: 'POST',
        path: '/',
        handler: (request, response) => response.redirect('/home'),
        config: {
            auth: {
              strategies: ['jwt'],
              payload: 'required'
            }
          }
        }
      ]);

This route will, when a JWT is posted failover from the authentication phase to the payload authentication phase, extract a JWT, store it in the YAR session cache and redirect the user to the /home path using a standard 302 response. When the handler for /home is JWT protected, the customExtractionFunc defined in the auth strategy will read the JWT from the users session cache and use it for authentication

Advanced/Alternative Usage => Bring Your Own `verify`

While most people using hapi-auth-jwt2 will opt for the simpler use case (using a Validation Function validate - see: Basic Usage example above - which validates the JWT payload after it has been verified...) others may need more control over the verify step.

The internals of hapi-auth-jwt2 use the jsonwebtoken.verify method to verify if the JWT was signed using the JWT_SECRET (secret key).

If you prefer specifying your own verification logic instead of having a validate, simply define a verify instead when initializing the plugin.

verify - (optional) the function which is run once the Token has been decoded (instead of a validate) with signature async function(decoded, request) where:
- decoded - (required) is the decoded but unverified JWT received in the request.
- request - (required) is the original request received from the client
- Returns an object { isValid, credentials } where:
  - isValid - true if the JWT was valid, otherwise false.
  - credentials - (optional) alternative credentials to be set instead of decoded.

The advantage of this approach is that it allows people to write a custom verification function or to bypass the JWT.verify completely. For more detail, see: use-case discussion in #120

Note: nobody has requested the ability to use both a validate and verify. This should not be necessary because with a verify you can incorporate your own custom-logic.

Compatibility

hapi-auth-jwt2 version 10.x.x is an optional upgrade that includes a breaking change. Several users of the plugin requested that the artifacts returned on successful authentication be an Object instead of a String. Sadly this is a breaking change, hence the new major release.

hapi-auth-jwt2 version 9.x.x is compatible with Hapi.js 19.x.x which only supports Node.js 12+. While hapi-auth-jwt2 version 9.0.0 does not have any code changes from v8.8.1 (so there should not be any need to update your code that uses this plugin), we felt it was prudent to make it clear to people that Hapi.js (the core framework) has dropped support for Node.js 10 and people should treat this package as no longer supporting the older versions of Node.

hapi-auth-jwt2 version 8.x.x is compatible with Hapi.js version 17.x.x - 19.x.x

hapi-auth-jwt2 version 7.x.x is compatible with 16.x.x 15.x.x 14.x.x 13.x.x 12.x.x 11.x.x 10.x.x 9.x.x and 8.x.x Hapi 17.x.x is a major rewrite that's why version 8.x.x of the plugin is not backward compatible!

However in the interest of security/performance we recommend using the latest version of Hapi.

Production-ready Examples?

Using PostgreSQL?

See: https://github.com/dwyl/hapi-login-example-postgres

Using Redis

Redis is perfect for storing session data that needs to be checked on every authenticated request.

If you are unfamiliar with Redis or anyone on your team needs a refresher, please checkout: https://github.com/dwyl/learn-redis

The code is at: https://github.com/dwyl/hapi-auth-jwt2-example and with tests. please ask additional questions if unclear!

Having a more real-world example was seconded by @manonthemat see: hapi-auth-jwt2/issues/9

Real World Example ?

If you would like to see a "real world example" of this plugin in use in a production web app (API) please see: https://github.com/dwyl/time/tree/main/api/lib

app.js registering the hapi-auth-jwt2 plugin: app.js#L13
telling app.js where to find our validate Function: app.js#L21
validate Function (how we check the JWT is still valid): api/lib/auth_jwt_validate.js looks up the person's session in our ElasticSearch Database if the session record is found (valid) and not ended we allow the person to see the restricted content.
Signing your JWTs: in your app you need a method to sign the JWTs (and put them in a database if that's how you are verifying your sessions) ours is: api/lib/auth_jwt_sign.js

If you have any questions on this please post an issue/question on GitHub: https://github.com/dwyl/hapi-auth-jwt2/issues (we are here to help get you started on your journey to hapiness!)

Motivation

While making Time we want to ensure our app (and API) is as simple as possible to use. This lead us to using JSON Web Tokens for Stateless Authentication.

We did a extensive research into existing modules that might solve our problem; there are many on NPM:

but they were invariably too complicated, poorly documented and had useless (non-real-world) "examples"!

Also, none of the existing modules exposed the request object to the validate which we thought might be handy.

So we decided to write our own module addressing all these issues.

Don't take our word for it, do your own homework and decide which module you prefer.

Why hapi-auth-jwt2 ?

The name we wanted was taken. Think of our module as the "new, simplified and actively maintained version"
