xoauth2

XOAuth2 token generation with node.js

Installation

npm install xoauth2

Usage

xoauth2 generates XOAUTH2 login tokens from provided Client and User credentials.

Use xoauth2.createXOAuth2Generator(options) to initialize Token Generator

Possible options values:

• user (Required) User e-mail address
• accessUrl (Optional) Endpoint for token generation (defaults to https://accounts.google.com/o/oauth2/token)
• clientId (Required) Client ID value
• clientSecret (Required) Client secret value
• refreshToken (Required) Refresh token for an user
• accessToken (Optional) initial access token. If not set, a new one will be generated
• timeout (Optional) timestamp for when the initial access token times out. In milliseconds after 1.1.1970.

See https://developers.google.com/accounts/docs/OAuth2WebServer#offline for generating the required credentials

Methods

Request an access token

Use xoauth2obj.getToken(callback) to get an access token. If a cached token is found and it should not be expired yet, the cached value will be used.

Request for generating a new access token

Use xoauth2obj.generateToken(callback) to get an access token. Cache will not be used and a new token is generated.

Update access token values

Use xoauth2obj.updateToken(accessToken, timeout) to set the new value for the xoauth2 access token. This function emits 'token'

Events

If a new token value has been set, 'token' event is emitted.

xoauth2obj.on("token", function(token){
    console.log("User: ", token.user); // e-mail address
    console.log("New access token: ", token.accessToken);
    console.log("New access token timeout: ", token.timeout); // timestamp after 1.1.1970 in seconds
});

Example

var xoauth2 = require("xoauth2"),
    xoauth2gen;

xoauth2gen = xoauth2.createXOAuth2Generator({
    user: "user@gmail.com",
    clientId: "{Client ID}",
    clientSecret: "{Client Secret}",
    refreshToken: "{User Refresh Token}"
});

// SMTP/IMAP
xoauth2gen.getToken(function(err, token){
    if(err){
        return console.log(err);
    }
    console.log("AUTH XOAUTH2 " + token);
});

// HTTP
xoauth2gen.getToken(function(err, token, accessToken){
    if(err){
        return console.log(err);
    }
    console.log("Authorization: Bearer " + accessToken);
});
