OAuth 2 Provider for Connect & Express
This is a node.js module for implementing OAuth2 servers (providers) that support server-side (code) and client-side (token) OAuth flows.
It's very customizable, so you can (and currently, must) take care of OAuth token storage and client lists. In the future, a Mongo or Redis backed abstraction will be provided so you don't need to care about any kind of storage at all.
Using it with npm
If you're using this module via npm, please be sure the bracket the
version in your app's package.json
file. Major versions may have an
incompatible API that's not backwards-compatible, so use a safe version
range under dependencies
(eg. for version 1.x):
"oauth2-provider": "1.x"
Quick Start
Install via npm:
npm install oauth2-provider
You can add it to your Connect or Express application as another middleware.
Be sure to enable the bodyParser
and query
middleware.
The OAuth2Provider instance providers two middleware:
oauth()
: OAuth flow entry and access token generationlogin()
: Access control for protected resources
The most important event emitted by OAuth2Provider is access_token
, which
lets you set up the request as if it were authenticated. For example, to
support both cookie-authenticated and OAuth access to protected URLs, you
could populate req.session.user
so that individual URLs don't need to
care about which type of authentication was used.
To support client authentication (sometimes known as xAuth) for trusted
clients, handle the client_auth
event to exchange a username and password
for an access token. See examples/simple_express4/app.js
.
Example
Within the examples sub-folder matching your preferred version of Express (for example, examples/simple_express4
), run npm install
and then run:
node app.js
Visit http://localhost:8081/login to gain access to http://localhost:8081/secret or use OAuth to obtain an access token as a code (default) or a token (in the URL hash):
- code: http://localhost:8081/oauth/authorize?client_id=1&redirect_uri=http://myapp.foo/
- token: http://localhost:8081/oauth/authorize?client_id=1&redirect_uri=http://myapp.foo/&response_type=token
