JavaScript Applications Course Repository

The JavaScript Applications course introduces first steps for build web front-end application, using a back-end server (Node.js/Business clouds/etc...). The topics covered include HTTP, AJAX (both native and with frameworks), asynchronous paradigms using callbacks and promises and more...

All homeworks for the course are test-driven, i.e. each task has a predefined set of unit tests. Here you can find information how to setup your machine for local testing

Preparing the local machine for Unit testing with Mocha and Chai

• Install JavaScript I/O
  • Try if it is working by typing in CMD/Terminal $ iojs -v (should produce result)
• Open CMD/Terminal and run $ npm install -g mocha

Preparing for the tests for each homework

• Checkout the repository for the particular homework
• Open CMD/Terminal and navigate to the checked out repository with the homework
• Run npm install in CMD/Terminal
  • A folder node_modules should appear
• You are ready to run the tests

Running the tests

• Navigate to the folder of the particular homework in CMD/Terminal
• Requirements:
  • JavaScript files must be called task-1.js, task-2.js etc..
  • Each .js file must contain module.exports=[name of the object/function]
• Run npm test
  • Test results should appear on the CMD/Terminal

Upload in BGCoder.com

• Go to the specific homework

• Select the task you will be sending

• Wrap your result in:

  function solve() {
      return [your solution object/function];
  }
