The goal of this assignment is to retrieve news in the RSS format from a remote server and display the contents to a user. It must be solved in node.js.
Implement a view of a RSS news feed, where at least these following fields can be read:
- Title
- Publication date
- Link to each news item in the feed, so that clicking the link will take the end-user to that external news page
- Make the RSS URL editable, so that the end-user is able to change it
- Provide a sort option for the end-user
Make your own ‘Promise’ in Node.js, without use of dependencies.
Implement a validate-function, that fulfills the userstory below:
-
The function should return a validation number that is calculated by adding all digits in the input.
-
If the result of this sum has more than a single digit, another iteration is required, repeat the process until a single digit number is calculated.
-
Example: for the input "444444" the sum of all the digits is 24. Since this is not a single-digit number, 2 and 4 should be added, and the result, 6, is the validation number that the validate function should return.
yarn install
yarn start
Browse it at http://localhost:3000/task-b/:number
curl http://localhost:3000/task-b/444444
will return
{ "history": ["444444", 24, 6], "result": 6 }Meaning, it goes to the process of summation of its sum which called history and the validation is called result.
