  clientID: 'my-client-id',
  clientSecret: 'my-client-secret',
  tokenPath: '/oauth/token',
  userInfoPath: '/oauth/userinfo',
  accessTokenName: 'token'
};

var accessToken = new AccessToken(options);

var token = accessToken.token(token);

if (token.expired) {

  token.refresh(function (err, newToken) {

    if (err) throw new Error(err);

    // to validate token
    accessToken.valid(newToken, function (err, valid) {
      console.log('Is token valid? ', valid);
    });
  });
}

// get a new token if expired or return the same one

token.get(function (err, token) {

  if (err) throw new Error(err);

  console.log('This should be a valid token', token);
});

// you can also validate the access token against oauth server

token.valid(function(err, valid){
  if (err) throw new Error(err);

  console.log('Is token valid', valid);
});

API

The token format referenced bellow as some methods first argument is an object like this:

var token = {
  access_token: 'access token'
  refresh_token: 'refres token'
  expired_in:  86400 // 24 hours
  expired_at: 1389602392 // specific unix time token will expire
}

AccessToken(config)

Create an AccessToken instance

var accessToken = new AccessToken(config);

or

var accessToken = AccessToken(config);

Configuration options are:

  • site: OAuth provider site.
  • clientID: OAuth client id.
  • clientSecret: OAuth client secret string.
  • tokenPath: OAuth token path (default is /oauth/token).
  • userInfoPath: User information path (default is /oauth/userinfo).
  • accessTokenName: The access token field name (default is access_token).

AccessToken#token(token)

Wrap a token with magic.

var accessToken = AccessToken(config);
var token = accessToken.token(token);

token#expired

Check to see if an access token is expired.

if (token.expired) {
  console.log('Token is expired');
}

token#valid(fn)

token.valid(function (err, valid) {
  if (err) {
    console.log('There was an error validating');
  }

  console.log('Is token valid', valid);
});

Check to see if an access token is valid by requesting the oauth provider server.

token#refresh(fn);

Get a new and fresh access token from the oauth provider.

token.refresh(function (err, newToken) {
  if (err) throw Error(err);
  console.log('New access token is', newToken);
});

token#get(fn);

If the token has expired, it will fetch a new .. one, otherwise it will return the current access token.

token.get(function (err, token) {
  if (err) throw Error(err);
  console.log('This is a valid accesst token', token);
});
