Google Reader Auth

Google Reader Auth uses the OAuth module to simplify logging in to Google Reader. It tries to remember the credentials so that the log in process can be automated after the first successfull manual log in.

Exported Functions

authWithGoogle()

Starts the authentication process. You will always want to call this function after setting up your event handlers.

continueAuth(code)

Continues the authentication process after it was stopped because it needed the user to approve that the application was allowed to access the user's data.

The 'code' parameter is the verification code provided by Google. It is needed to be able to continue authenticating.

Generated Events

'authDone' (access_token, access_token_secret)

This is generated when the authentication process is finished. It is now possible to access the user's data.

When catching the envent two parameters are passed along, the oauth access token and the oauth access token secret. They should be used with the functions from the OAuth module, for example 'get()'.

'verificationCodeNeeded' (url)

Generated when no valid access token and access token secret can be found in the configuration file.

Ask the user to go to the url provided (or automatically show them the page at that url). Google will generate a verification code that is needed to complete the authentication. Pass this code to the 'continueAuth(code)' function.

'error' (error)

This event is generated whenever an error occurs.

The parameter is a standard node.js error object with for example a 'stack' property.

Usage Example

Make sure you install the inireader and oauth modules first (for example using npm). Also create a file in the same dir as the example called 'conf.ini' with one single line that says '[auth]' (for example by running 'echo "[auth]" > conf.ini' in your terminal).

Now you're ready to run the following example:

var GoogleAuthorizer = require('googlereaderauth').GoogleAuthorizer;
var googleAuth = new GoogleAuthorizer();

googleAuth.on('authDone', function(access_token, access_token_secret) {
    var unixTimestamp = new Date().getTime();
    var url = 'http://www.google.com/reader/api/0/user-info?client=googlereaderauthexample&ck=' + unixTimestamp;
    googleAuth.oa.get(url, access_token, access_token_secret, function(error, data) {
        console.log(JSON.parse(data));
    });
});

googleAuth.on('verificationCodeNeeded', function(url) {
    console.log('Please go to ' + url);
    console.log('Please enter the verification code:');
    process.stdin.resume();
    process.stdin.once('data', function(code) {
        googleAuth.continueAuth(code.toString().trim());
    });
});

googleAuth.authWithGoogle();
