Simple todo application with a web frontend and API backend with a datastore.

Specs:

• The back-end is a RESTful API based on Node.js + Express, using MongoDB for the database. The front-end is based on AngularJS and it uses the API to communicate with the backend, not using serverside rendering of templates.
• The UI is separate from the business logic and data layer.
• For unit test coverage, Mocha, the JavaScript test framework (https://mochajs.org/) + Supertest (https://www.npmjs.com/package/supertest) are used. There are a number of unit tests are placed in the app/tests/unit.js file. See the steps below on how to run the tests. Not all possible tests were written for the Todo model.
• For end-to-end test coverage, Protractor, the JavaScript test framework (http://angular.github.io/protractor/#/) + Selenium (http://www.seleniumhq.org/projects/webdriver/) are used. There are a number of e2e tests are placed in the app/tests/e2e.js file. See the steps below on how to run the tests. Not all possible tests were written the app.

Installation instructions:

• Download (if you have Node.js installed ignore this step) and install Node.js from here: https://nodejs.org/en/download/

• Install the project and its dependecies, by opening the terminal and navigating to the project folder: $ cd FOLDER_PATH $ npm install --save

• In the case your environment lacks some modules, you might be requied to install them.

• Run locally when being in the project folder: $ node server.js

• Open the browser and go to the following URL: http://localhost:3000/

• Run the server using Nodemon (automatically restarts the server when there are changes to the files). $ nodemon server

Run the unit tests:

• Open a terminal window (iTerm) and go to the path of the cloned folder using the command: $ cd YOUR_FOLDER_PATH
• Go to the tests folder using the command: $ cd app $ cd tests
• Run the tests using: $ mocha unittests

Run the end-to-end tests:

• Install Protractor and WebDriver Selenium: $ sudo npm install -g protractor $ sudo webdriver-manager update
• While the Node.js server is running, start the webdriver-manager: $ webdriver-manager start
• Open a new tab in the terminal and go to the folder path: $ cd FOLDER_PATH
• Then run: $ protractor protractor.conf.js

See below the steps on how to test the API using Postman:

1. Open Postman

2. For viewing all Todos, use the GET request on the following url after starting the application: http://localhost:3000/todos

3. For creating a todo, use the POST request on the following url: http://localhost:3000/todos
 	In the POST request body choose: x-www-form-urlencoded
 	Add the following Key in the Body of the request: "text". For the defined Key add data that represents the text of the todo.
 	Run the request, a new todo will be created with the inputted data.

5. For updating a todo, use the PUT request on the following url: http://localhost:3000/todos
	In the PUT request body choose: x-www-form-urlencoded
 	Add the following Key in the Body of the request: "text". For the defined Key add data that represents the text of the todo.
 	Add an id key that contains an existing ID of a previously created todo (run GET to view all existent todos).
 	Run the request, the selected todo is now updated with the inputted data.

6. For deleting a todo, use the DEL request on the following url: http://localhost:3000/todos
	In the DEL request body choose: x-www-form-urlencoded
 	Add an id key that contains an existing ID of a previously created todo.
 	Run the request, the selected todo is now deleted.
