OAuth Modules for Node.js - Supporting RSA, HMAC, PLAINTEXT, 2-Legged, 3-Legged, 1.0a, Echo, XAuth, and 2.0

If you're looking for the popular OAuth Bible, here it is. It extensively explains the multitude of OAuth flows and how OAuth works.

npm install mashape-oauth

• Handles binary responses
• Handles gzipped responses
• Supports having an empty oauth_token for 1.0a
• Supports Plaintext, HMAC-SHA1, and RSA encryption for 1.0a
• Object based parameter system and supports chaining
• Code has been refactored to be more performant in loops, whiles, and callback structures.
• Intuitive method naming, small footprint, and tested against test suites as well as hundreds of APIs.

Require the library and the one you wish to use.

var OAuth = require('mashape-oauth').OAuth;
var oa = new OAuth({ /* … options … */ }, callback);

• options Object OAuth request options
  • echo Object Optional If it exists we treat the request as OAuth Echo request. See Twitter
    • verifyCredentials String What is the credentials URI to delegate against?
  • realm String Optional Access Authentication Framework Realm Value, Commonly used in Echo Requests, allowed in all however: Section 3.5.1
  • requestUrl String Request Token URL. Section 6.1
  • accessUrl String Access Token URL. Section 6.2
  • callback String URL the Service Provider will use to redirect User back to Consumer after obtaining User Authorization has been completed. Section 6.2.1
  • consumerKey String The Consumer Key
  • consumerSecret String The Consumer Secret
  • version String Optional By spec this is 1.0 by default. Section 6.3.1
  • signatureMethod String Type of signature to generate, must be one of:
    • PLAINTEXT
    • RSA-SHA1
    • HMAC-SHA1
  • nonceLength Number Optional Length of nonce string. Default 32
  • headers Object Optional Headers to be sent along with request, by default these are already set.
  • clientOptions Object Optional Contains requestTokenHttpMethod and accessTokenHttpMethod value.
  • parameterSeperator String Optional Seperator for OAuth header parameters. Default is ,

oa.getOAuthRequestToken({ /* … parameters … */ }, callback);

• parameters Object Optional Additional Headers you might want to pass along.
  • If omitted, you can treat parameters argument as callback and pass along a function as a single parameter.
• callback Function Anonymous Function to be invoked upon response or failure.

oa.getOAuthRequestToken(function (error, oauth_token, oauth_token_secret, results) {
  if (error)
    return res.send('Error getting OAuth Request Token: ' + error, 500);
  else
    // Usually a redirect happens here to the /oauth/authorize stage
    return res.send('Successfully Obtained Token & Secret: ' + oauth_token + ' & ' + oauth_token_secret, 200);
});

oa.getOAuthAccessToken(options, callback);

• options Object
  • oauth_verifier String Verification code tied to the Request Token. Section 2.3
  • oauth_token String Request Token
  • oauth_token_secret String Request Token Secret, used to help generation of signatures.
  • parameters Object Optional Additional headers to be sent along with request.
  • callback Function Optional Method to be invoked upon result, over-ridden by argument if set.
• callback Function Anonymous Function to be invoked upon response or failure, setting this overrides previously set callback inside options object.

oa.getOAuthAccessToken({
  oauth_verifier: 'ssid39b',
  oauth_token: 'request_key',
  oauth_token_secret: 'request_secret'
}, function (error, token, secret, result) {
  if (error)
    return res.send('Error getting Auth Access Token: ' + error, 500);
  else
    // Usually you want to store the token and secret in a session and make your requests after this
    return res.send('Successfully Obtained Token & Secret: ' + token + ' & ' + secret, 200);
});

oa.getXAuthAccessToken(username, password, callback);

• username String XAuth Username credentials of User obtaining a token on behalf of
• password String XAuth Password credentials of User obtaining a token on behalf of
• callback Function Anonymous Function to be invoked upon response or failure.

oa.getXAuthAccessToken('nijikokun', 'abc123', function (error, oauth_token, oauth_token_secret, results) {
  if (error)
    return res.send('Error getting XAuth Access Token: ' + error, 500);
  else
    // Usually you want to store the token and secret in a session and make your requests after this
    return res.send('Successfully Obtained Token & Secret: ' + oauth_token + ' & ' + oauth_token_secret, 200);
});

oa.post(options, callback);
oa.get(options, callback);
oa.delete(options, callback);
oa.patch(options, callback);
oa.put(options, callback);

// Alternatively, you can use the old node-oauth style: (Where method is one of five above.)
oa.method(url, oauth_token, oauth_token_secret, body, type, parameters, callback);

• options Object Contains Request Information
  • url String URL to be requested upon
  • oauth_token String Optional; Dependant upon request step, could be access, or request token.
  • oauth_token_secret String Optional; Dependant upon request step
  • body String Optional; Body information to be sent along with request.
  • type String Optional; Content Request Type
  • parameters Object Optional; Additional headers you wish to pass along with your request.
  • callback Function Optional; Method to be invoked upon result, over-ridden by argument if set.
• callback Function Method to be invoked upon result, over-rides options callback.

var OAuth2 = require('mashape-oauth').OAuth2;
var oa = new OAuth2({ /* … options … */ }, callback);

• options Object OAuth Request Options
  • clientId String Client Identifier
  • clientSecret String Client Secret
  • baseUrl String Base url of OAuth request
  • authorizationUrl String Optional; Authorization endpoint, default is /oauth/authorize
  • authorizationMethod String Optional; Authorization Header Method, default is Bearer
