Create a single page web application to manage a task list using plain JavaScript.
The application provides the functionality to view the list of to-do items, create them, and mark them as done. The front-end technology is based on JavaScript / HTML / CSS. Tasks are stored using a Rest service. Please realize data transfer between web client and back-end service.
The server-side implementation is provided and implemented based on Node.js. The API is documented below. Please deliver an appealing, well-crafted and creative solution. You are free to extend the feature set. Try to use as few libraries as possible, we want to see your understanding of standard web technologies and thus plain JavaScript is preferred.
Don't forget to polish your user interface with your flavor of CSS.
The back-end is based on Express, a Node.js web application framework.
To setup the server install Node.js in Version 4.4 or newer from the Node.Js Website. Then run the following command in the project root. This downloads all required dependencies to run the Server.
npm installRun the following command in the project root:
npm startThis is the main entry point, the server delivers the index.html file which is located in the project's public folder. Static files in public are served as well.
