Hacker Dormitory Application built with React

React: Hacker Dormitory

Given a partially completed React application with the HTML template and few built-in functionalities, your task is to implement a resident directory that makes note of a list of residents in the dormitory.

Certain core React functionalities have already been implemented. Complete the React application as shown below in order to pass all the unit tests.

The application has 3 Components:

  • The Search view, which has two inputs: ‘Student Name’, where the user can type a student’s name, and ‘Joining Date’, a date field denoting when the student will join the dormitory.
  • The ResidentsList view, which shows all the residents’ names.
  • The Error view, which is shown in case of an error.

The studentsList.js file holds the STUDENTS constant, which holds the name and validityDate of all the students who are part of the college. The structure of the STUDENTS variable is as follows:

  • name: The name of the student. <String>
  • validityDate: The last valid day the student can be added to the dormitory. <String> of format <yyyy-mm-dd>

The function checkValidity takes two arguments: joiningDate and validityDate. It needs to be called to check if the student’s joining date is valid.

  • joiningDate: The date when the student will join the dormitory. <String> of format <yyyy-mm-dd>
  • validityDate: The last valid day the student can be added to the dormitory. <String> of format <yyyy-mm-dd>

The app should implement the following functionalities:

  • On providing student’s name and joining date, the following should happen:
    • It should check for the student’s name in the STUDENTS list , without case sensitivity.
    • The checkValidity(…) function needs to be called to check if the student’s joining date is valid.
  • If the student is part of the college and the joining date is valid, then they should be added to the ‘Residents List’ <ul>.
  • If the student  is not part of the college, then show the following error message:
    • “Sorry, <NAME> is not a verified student!”
    • <NAME> represents the name of the student who is being checked if they are part of the college.
  • If the student’s name is valid but the joining date is after the student’s validity date, then show the following error message:
    • “Sorry, <NAME>‘s validity has Expired!”
    • <NAME> represents the name of the student whose validity is being checked for.
  • After adding each student, the form should be cleared out.

Note:

  • Retrieve the list of college students from the studentsList.js file.

The following data-testid attributes are required in the component for the tests to pass:

  • The ‘Student Name’ <input> tag should have the data-testid ‘studentName’.
  • The ‘Joining Date’ <input> tag should have the data-testid ‘joiningDate’.
  • The ‘Add’ <button> tag should have the data-testid ‘addBtn’.
  • The error message <div> tag should have the data-testid ‘errorMsg’.
  • The ‘Residents List’ <ul> should have the data-testid ‘residentsNameList’.

Please note that the component has the above data-testid attributes for test cases. It is advised not to change them.
