Angular-Passport + Ionic app + CORS requests

An AngularJS application that uses Passport, MongoDB. Demonstrating:

• Authentication using Passport
• Account creation and server validation with Mongoose.
• CRUD interface for creating posts with MongoDB
• Client validations for account creation including a directive for validating if a username is available.
• Authorization middleware for checking if you are allowed to edit a post.
• Unit tests for client code *Ionic app consuming Node server

Ionic proxy server

This project is primarily set up to show you how to access API's without CORS using the Ionic proxy server.

How to use angular-passport

Before you continue, make sure you have MongoDB installed http://www.mongodb.org/downloads/.

Setup

Run npm install, followed by bower install to grab the dependencies.

Setup Ionic

Run cd ionic, followed by npm install to grab the dependencies. Run ionic serve, or ionic serve --lab to grab the dependencies.

Running the app

Run grunt server to start the app in development mode with livereload, or run grunt server:dist to run it in a minified and optimized production build.

Manage CORS in IONIC app

There are two parts to this project:

• The Api Server hosted at http://localhost:3000 - node server.js
• The Ionic web server hosted at http://localhost:8100 - ionic serve

We want to make requests to the Api server at localhost:3000 from the Ionic server at localhost:8100 via an AJAX request. This will require CORS and fail due to the Api server not allowing the origin localhost:8100 if we use ionic serve or ionic run -l:

XMLHttpRequest cannot load http://localhost:3000/api/endpoint. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.

Points of reference

See ionic.project for configuring the proxy server. Notice how we set the path to /api - signifying any request to the Ionic server http://localhost:8100/api will retrieve requests to the proxyUrl at http://localhost:3000/api/endpoint.

See www/js/app.js for setting up the Api Endpoint as an AngularJS constant. Notice here the address is pointed at the Ionic server.

See www/js/services.js for using the AngularJS constant.

See www/js/controllers.js for using the AngularJS service.

See gulpfile.js to see how the gulp tasks are set up to replace your URL's in your files.
