OAuth 2.0 provider toolkit for nodeJS with connect/express support. Supports all the four authorization flows: authorization code, implicit, client credentials, password.
One more oAuth 2.0 service provider? Yes!
- Based on the final specification RFC6749
- Fully customizable and extremely flexible
- Test covered
- Contains integration examples
$ npm install oauth20-provider
Look into ."/test/server/ directory" for working example with in-memory and redis storage models.
By default module sets abstract models which should be redefined, library does not force any implementation.
Refresh tokens are credentials used to obtain access tokens. Refresh tokens are issued to the client by the authorization server and are used to obtain a new access token when the current access token becomes invalid or expires, or to obtain additional access tokens with identical or narrower scope (access tokens may have a shorter lifetime and fewer permissions than authorized by the resource owner).

Redefinable functions Look at "./lib/model/refreshToken.js" for further information.
Access tokens are credentials used to access protected resources. An access token is a string representing an authorization issued to the client. The string is usually opaque to the client. Tokens represent specific scopes and durations of access, granted by the resource owner, and enforced by the resource server and authorization server. Read more
Redefinable functions Look at "./lib/model/accessToken.js" for further information.
Before initiating the protocol, the client registers with the authorization server. The means through which the client registers with the authorization server are beyond the scope of this specification but typically involve end-user interaction with an HTML registration form. Read more
Redefinable functions Look at "./lib/model/client.js" for further information.
The authorization code is obtained by using an authorization server as an intermediary between the client and resource owner. User only by authorization code flow, no need to initialize it if one don't use this grant. Read more
Redefinable functions Look at "./lib/model/code.js" for further information.
User is a registered person in the service. Model should contain unique identifier, password and sometimes additional unique key (for example username/email). There is no common scheme for this type of object, feel free to implement it your way.
Redefinable functions Look at "./lib/model/user.js" for further information.
Page is used to ask user whether user agree or not to allow client to access his information with current scope. Controller should return POST form with decision parameter (0 - user does not allow, 1 - user allows).
Redefinable Look at "./controller/authorization/decision.js" for further information.
First of all include and initialize oauth20-provider library:
oauth2lib = require('./oauth20-provider.js');
oauth2 = new oauth2lib({log: {level: 2}});Library is compatible with express/connect servers, inject oauth2 into your server.
server.use(oauth2.inject());Token endpoint
server.post('/token', oauth2.controller.token);Authorization endpoint
server.get('/authorization', isAuthorized, oauth2.controller.authorization, function(req, res) {
// Render our decision page
// Look into ./test/server for further information
res.render('authorization', {layout: false});
});
server.post('/authorization', isAuthorized, oauth2.controller.authorization);Middleware isAuthorized is used to check user login. If user is not logged in - show authorization form instead. Simple implementation:
function isAuthorized(req, res, next) {
if (req.session.authorized) next();
else {
var params = req.query;
params.backUrl = req.path;
res.redirect('/login?' + query.stringify(params));
}
};Your authorization server is ready for work.
- Add examples (mongodb, postgresql)
- Allow multiple flows for single client (only 1 per client works well yet)
- Add refresh token TTL
- Implement proper "TTL" support for accessToken and scope objects
- Add MAC token type
- Allow client authentication via query parameters
- More tests
- More docs
- Build example site
- Check RFC once more
