Node.JS Easy 3rd party OAuth & REST API Consumer
Make consuming RESTful apis waaaaay easier in Node.js
Ever notice how all of these APIs seem to have a high degree of consistency? They're just a bunch of URLs that accept different parameters you pass to it. So the thing is what's the point of creating a lib for each and every API and endpoint, making each url call involve a different class or method name? This means that in addition to learning the API you have to learn the lib API too. And what happens if the API updates? You're stuck waiting for the lib to incorporate the changes before you can actually leverage the new features.
So with so much repetition from one API to another, I built a way to 'map' APIs. This means that updating and adding new APIs is ridiculously easy, and the only documentation you need to refer to is the native APIs, and even that is kept to a minimum. All methods calls are extremely simple and consistent. Just specify the CRUD action, the resource name and pass the parameters you have available to you. The mapper will figure out what url it needs to use to get the job done, leaving you to make much more versatile code without knowing every nuance of every API.
$ npm install resteasy
var resteasy = require'resteasy';
loginkey (appId) and a
passkey (appSecret). You can optionally pass the
oauth_token_secretif you stored it and want to reuse the session
// Instantiate an instance with config valuesvar keys = login: '[appId]' pass: '[appSecret]' ;//You must pass the full URL to where the callback is locatedvar callbackUrl = 'url';// var provider = resteasy('./providers/myprovider', ...);var github = resteasy'resteasy/lib/providers/github' keys callbackUrl;
...redirects user to API for authentication which then forwards to callbackUrl...
githubcallback// Store auth credentials;
You can either use the general-purpose
github.request() function to build your own queries if you are too lazy to
supplement a provider, but the preferred method is as follows:
var tokens =oauth_token: your stored tokenoauth_token_secret: your stored token secret;githubreadtokens 'repos' user: 'ProLoser' callback;
The syntax is identical for
.del(). The provider map will be searched until a path with all
of the REQUIRED params are matched is found. It will then proceed to use that endpoint.
You may need to pass fields, to get back the desired data.
To do this create an object and pass true for every field type you want.
var setFields ='first-name' : true'last-name' : true'positions' : true'educations' : true;
All it takes to add your own provider is a hashmap containing the specific API's endpoints in an organized manner.
To refer to your provider, just pass the path as the first argument (
github above) as if you were passing it directly to
Use this template and check out the other providers for examples:
